e85 vs race gas dyno. Jump to Latest Follow It's a waste of money. A reduced quantity of E85 is necessary to run a race engine previously set up for methanol. The octane is unregulated so it is all over the place from one fill to another , do a lot of reading and understanding before you for your own. Legally, 2% water is allowed in the fuel. Race gas is fantastic in it's properties and consistency, easier to flow than E85 as well with less side effects like o2 fowling and injector . Jump to Latest Follow 1 - 10 of 10 Posts. Custom blended racing E85 fuel would benefit from using anhydrous (dry) ethanol. E30 and 100 octane dyno graphs are pretty close. No point in mixing race gas and e85. 80 race gas in the car, it does make you giggle a little tho. 1; 2; 3; First 3 of 3 Go to page. But, I can tell you E85 will make more power then 110 easily. Just suck to lose gas mileage because of it (for those that drive the car regularly). "The difference between the two air/fuel ratios is. If jetted properly need feedback on any power loss or gains using gasoline 100% vs 90% gas + 10% ethanol. its a street driven car i just woukd feel safer gaining a little more from race fuel. Typically, similar setups are fuel system-limited by ethanol blended fuels before this power level. just looking for some input on benefits and cons of these and which one i should go with. Unfortunately the main reason that our customers started switching to E85 was due to the cost savings when compared to. E85 is a highly oxygenated fuel consisting of 85% ethanol and 15% gasoline. That's great for the environment, but if you're interested in performance the real value of E85 is that it provides race-fuel. Pump E85 is commonly used as a "poor man's" racing fuel, but the percentage of ethanol in pump E85 can vary quite a bit depending on the time of year and the blend provided by the distributor. E85 is the designation for an ethanol-blended fuel where ethanol makes up 85-percent of the content, and gasoline 15-percent. E85 difference: The fuel economy of our Tahoe on E85 under these conditions was 26. As you indicated it is much more stable than pump E85. By blending gasoline and ethanol at an 85/15 percent ratio (E85), the fuel becomes thirty percent less powerful. E85 fuel can give you a significant boost in power and torque without breaking the bank for racing fuels. 73 corrected cost of E85 x 5 gallons = $13. Same with 113, just go from 180 to 190 main, and gain a couple hp from the oxygenated fuel. The test doesn't just highlight dyno numbers and power/torque curves, but focuses on intricacies of tuning and. This is mainly due to E85 working with the LT1's high compression. Many say it is equivalent to 105-110 octane, meaning it has much higher knock-resistant properties than pump gas and is usually substantially cheaper. Cold starting on 2% of gasoline does not sound fun when most of us have a hard time with 30% (E-70) winter blend. On top of that, turbo response and midrange torque are even better on pump E85 than on race gas. It should pull a lot harder after shifts now in the 5000-5500 range. He also has the Lingenfelter Pump and injectors, you know how much that cost. Had a chance to get one the dyno yesterday with Adam from ZFG Racing working on the keyboard. I run 91 in my small block Nova, best of 11. Lets use this thread as a central repository for all of our dyno sheets. Butt dyno says slightly improved acceleration and faster revving. Gasoline and the physical differences…. Based on the results of the two dyno graph comparisons, you can see that with the same engine, tuner, and turbo combination this 1. A gallon of E85 is around 75K BTU vs. By Steve Turner April 14, 2017. Not big dyno numbers but this is what the car picked up by switching to E85. It's easy to make up the price of a fuel system paying for e85 vs race gas. It now has enough power for low 10-second and possibly high-9-second performance. 0:10 Pump E-85 Dyno Results0:34 Our . The 340 and 408 were faster on pump 93, the 434 made 30 more hp on the dyno on pump 93 than crate 98 race gas. Countless dyno results have proven to show, C85 makes 5% more than pump gas and the V8 supercar blend. 5" dual cat back exhaust with X-pipe (featuring GESI GSport 300 cell catalytic converters) Exxon 93 pump gas VS Sunoco 93 pump gas VS e30/93 octane ethanol blend; Testing Methodology. A good street gasoline is designed to burn efficiently from idle to 3,000 RPM which is the highest speed most engines see during the EPA test for exhaust emissions. The tune is still an E85 tune, but you will be able to apply obscene amounts of power to it. by wheels » Tue Mar 27, 2012 1:12 pm. " Why not try a gallon of Sunoco 103 Racing fuel or "Sunoco 100" Sunoco SS 100 is an unleaded high octane gasoline that is street-legal in California. E98 is the same price as E85 here which is basically the same price as pump gas. E85 can be perfect for the high horsepower or high compression build, as long as it is readily available in your area. VP offers its own version of E85, called C85. (stock 345 Hemi @370HP) again that is just a guess. RACE GAS has been tested and proven to increase the octane of pump gas to as high as 100 to 105 AKI, (R+M/2), when blended with gasoline as specified in our blend chart. 80 per gallon and adding ACES IV made the total price $4. E85 race fuels have an 85% ethanol concentration every time. The two 87 and 93 octane E10 fuels were sourced from the QuikTrip station in Suwanee, Georgia; the remaining fuels came from Hyperfuels, a dealer for Shell, VP and Sunoco race fuels. as far as using it for a daily driver, and getting cheaper gas. Can you access 100 octane as easily as E30/E85? Last time I checked, 100 octane was still quite a bit more expensive and the gains over ethanol are marginal. Here are the results! Pump gas results: 218whp/190wtq. That is one of the reasons the Mustang is not a Flexfuel car. This is a great case study on the main benefit of E85 as a fuel source when compared to pump gas. On the racing circuits that I follow and attend (Indy and CART), race fuel is now 100% ethanol or 90/10 ethanol/methanol. E85 e85 vs 93 DYNO RESULTS!!! Massive Difference. I have a local Exxon/Mobil Gas Station that offers 90 OCTANE ETHANOL FREE GAS AT A PREMIUM OF $4. The e85 took about an additional ~6 degrees of timing to make its best power. Back to Back Dyno testing has shown that E70 makes power near that of 105 octane race fuel, we also discovered that E85s power is near that of 114-116 octane race fuel, and the over all best blend we have found to work is E87, this has enough Gasoline in it to start the burn process but yet retains enough Ethanol to keep the cooling effects of. Because you want the power and safety of race gas daily, but without the $10/gallon price tag and be able to get it at many normal gas stations. Our racing Pro E85 does not contain pump gas or refinery drippings. With higher quality pure components, C85 is superior to E85 products. Customers will be supplied with video of their engine's dyno, along with the dyno and build sheets. I had a funco tuned on E80 and it used about 1-1/2 time the fuel of the race gas car. 7 witch is about right but it says im making 189 whp my car is stock but that seams off know i the pocket dyno says i pulled a 14. Hands down E-85 is the worst pump fuel you can buy the the Ethanol is not water free and the filtration at the pump does not include proper water removal systems. Well you are still using 15% Gasoline. definitely a good alternative to race fuel. Compare an edgy race gas tune to an E85 tune, identical EGT's, and I predict spool would be very similar. Results can obviously vary for different engines with different compression rations (and boost), but in this case, every single fuel except E85 resulted in basically same power and torque. i run 91 now and make 63hp/51tq with a 12-1 cp non corrected deck and +5 crank. E85 has about 75-80% of the BTUs as gasoline. 20, almost a dollar difference, so I want to be. In the case of E85 the difference is about a 20%-30% increase in exhaust gas volume on max power rich mixtures if I recall correctly, because you have to burn about 30% more fuel to get the same effective combustion mixture. Simply stated, this means that a gallon of ethanol has only 61 percent of the energy of a gallon of gasoline. Update: June 5 2014 - Stock FRS/BRZ with our E85 tune runs a 14. On my 23 degree 427 SBC E85 is worth at least. and I agree, if your looking for the best MPG, do not use fuel with ethanol as my personal experience is approx a 3-5% loss in mileage. Also, make sure your tank is completely empty and use the local Arco fuel without any additives for the tune. "I don't quote power numbers due to the huge variables from dyno to dyno. 0:10 Pump E-85 Dyno Results0:34 Our last champ up to thi. We tested E85 vs E10 in a FlexFuel Buick Regal Turbo and experienced a 12% drop in gas mileage. While mixing 85 percent 108-octane ethanol with 15 percent 93 octane would yield something in the 102 octane range, the fact is that most manufacturers mix it with 84 octane or lower. But compression is going to be set to 13. We have E70 here in the winter and the car adapts to this on the E85 tune, but I've been using the SCT Pro Racer Package to change the fuel stoich to 10. Add 100+ Horsepower for less than $100. 00 a gallon and we get 15mpg on E. The purpose behind e85 is cheap race gas(the impressive cooling ability is just a great bonus. The quantities needed are different: more E85 is needed than gasoline, typically 20- to 35-percent more. The E85 fuel around here (East central Indiana, West central Ohio) is too inconsistent. It's easy to say the next generation of an engine was better than its predecessor. “Pump fuels vary widely in tolerance. the E85 likes about 45% more fuel. Pump E85 is commonly used as a “poor man’s” racing fuel, but the percentage of ethanol in pump E85 can vary quite a bit depending on the time of year and the blend provided by the distributor. That’s great for the environment, but if you’re interested in performance the real value of E85 is that it provides race-fuel. Results were an impressive 418rw, only 8-10rw down from the 49% meth results! E85 really is the poor mans race gas. 4L HEMI in about an hour with no tuning required.

After jetting the blower carbs for E85, the power output jumped to 700. ly/2KlAS2T Check out this preview of Engine Masters Episode 30, . For those of you that have dyno'd both e85 and, say, 114 race fuel, (in an apples to apples comparison), what were your mods and how much of a difference did the dyno show? I'm up for a tune this weekend, not enough dyno time to tune for pump, e85, and 114. Because of E85s increased resistance to detonation, it allows for more power without the cost of expensive race fuels. We are lucky to be enjoying such a great platform. This is what gives is an advantage over petroleum based fuels despite a slightly lower energy density. I have these mods: GTC 3 intakes GTC downpipes GTC Titan full exhaust ASNU 1050cc injectors ASNU drop-in pumps Visconti Flex Fuel kit Ecutek e-tune by Ben The car made 530WHP on a mustang dyno running on E80 (per zeitronix), compared to a 430WHP baseline stock run, a. Do I need to change anything on my car to run E85? Usually you need to use larger fuel injectors than you would normally run and get the car dyno tuned. Unlike gas station blends that can legally range from 51%-85% ethanol, Ignite E85 is blended 85% ethanol with 15% denaturant. 0 is a flex fuel vehicle and the mustang gt is not? 12th gen at least as far as the f150 goes. a gallon of, say, 93 gasoline, is at about 115k BTU. This is our 2016 Twin Turbo V6 Dodge Challenger on our in house dyno running both 93 octane and E85. One of the problems with tuning E85 is that you really never know if your lean or fat until you test it with an wideband O2, reading the plugs doesn't always work because ethanol is a cleaning fuel and your plugs could look. The car is full bolt ons using a JB4 G4 15 ohm board (unless noted) with 91 octane fuel + 1 can of octane booster. I think it's impractical for a dd car. looks like i need to do some injector research for whats available. Using an E85 calibration with pump gasoline or race gas may result in engine damage. This fuel is not a straight tip in. My question: Is it better to run 90 Octane Ethanol free gas vs. Dyno room temps were in the 90s so we definitely were not going for any records, but did want to evaluate the general power differences between 49% meth (boost juice) vs. FrankenTurbo F21 on E85 (Dynapack Dyno) And some results of the F21's on 91 octane fuel. And of course, we love to compare to the 8th gen pump gas vs pump gas, same dyno. Supercharged LS1, stroked to 383 cubes. Also, it used about 35% more fuel when on E85 vs race gas. Race fuel will make more power then E85. Wanted to get some feedback on race fuel to run in my zx10.

The fuel brings a dramatic improvement to the timing of a car without the use of methanol or race gas. Answer (1 of 13): Performance difference of the fuels? Or the performance differences of an engine using each? They answer changes depending on the question. Patti states, "E85 (or flex fuel) is an industry term that refers to ethanol-gasoline blends containing 51- to 83-percent ethanol, depending on geography and season. The jump from a Gen 1 (2011-'14) to Gen 2 (2015-'17. To ensure a level playing field, they used Rockett Brand's 114-octane race gas and 112-octane E85 racing fuel. Until very recently they ran 100% methanol. Plan is get a very conservative 93 tune that is safe to run on pump gas when needed, and then create tunes for E85 and 100 octane race gas for when things can be rowdy. Although efficiency gains can be realized by slightly reducing the timing advance when running E85. E85 is 85% ethanol, so is less dense as a fuel so more has to be burnt to create the same power. FBO E85 vs Stock Dyno Results - posted in Power and Drivetrain: Hey guys, Just got back from the dyno with my 2015 FBO E85 car. How Does Ethanol Affect Gas Mileage?. With the right tuning, it is possible to make nearly 100w HP difference on E85. While power itself is never a clear comparison across different dynos, hopefully this will eventually allow us to. On the other hand, when the Indy Car League converted from methanol to straight ethanol, dynamometer tests revealed a reduction in power after the conversion. Gasoline Comparison Test Marvel Mystery Oil or ATF work well. Because ethanol requires more energy to burn, your vehicle will have to work harder. I'm running full E85 and other then the tune the truck has 0 power mods. On this set up, running E85 produced big gains over using 114 octane race gas. Because my competitor uses THIS forum i believe going to keep some spec hidden lol. My car dyno'd 360hp @ 16psi on e-85. It has a base octane rating of 105 . 05 in the 1/8 over non oxygenated race gas, however Q16 is worth about. I didn’t want to mess with testing pump E85 to make sure it’s correct and adding 91 to get it right, draining the tank at the end of the season, using more fuel and having to haul more fuel. “It made more power on E85,” confirms R&R’s Ron Quarnstrom. Run a clean tank of gas do a dyno then do a 10% mix run on the dyno. You need 15% more of ethanol, but because ethanol doesn't flow as well as normal fuell. E85 Conversion & Tuning Info. 8:1 on the dyno but well see what she likes on the street, was about 6-8% difference between 93 vs mr12. 2:1 compression ratio, crate engine, done by Wheel to Wheel Powertrain in Madison Heights Michigan. With these cars in N/a form, being able to run more timing from e85 will make the motor work more efficient. The biggest difference will be the amount of fuel needed. E85 dyno testing Bikeland member Wrongway stopped by with his zx14 to do a little dyno testing today His zx14 has nothing but slip ons and a PVC. VP Racing Fuels also claims that C85 is superior to E85 in terms of cooling effect, resistance to detonation and corrosion. A: It has been our experience that E85 with its 105 octane rating and high tolerance to detonation is superior to premium pump gas and equal to and in most cases better than 110 octane race gas. I guess if there is enough interest I could redyno my car with 93 and 110 octane; however I practically need to take out a loan for race gas these days. They've ran LS3 on engine dyno with 87, 91 pump gas, 110 and 113 race gas and E85 - adjusting timing and AFR for max power/torque. Not spraying nitrous but thinking bout tuning. The company says it provides a more consistent blend than gas stations, which offers varying percentages of ethanol. 2 engine, and recently dyno'ed my 461 SB2. The "dry" in Avgas means it is certified to contain much less water, which will freeze.

On this episode of Engine Masters presented by AMSOIL, we test the power differences between 118-octane race gas and Rockett Brand E85 ethanol-blended fuel. One reason E85 can make [ a little ] more power than race gas is because it is so heavily oxygenated (30%+ oxygen by weight). Incidentally, my engine picked up power on the E85 fuel (runs 10. E85 fuels, an ethanol fuel blend containing up to 85% denatured ethanol and gasoline or other hydrocarbons, have become increasingly more common on roadways as flex-fuel vehicles take advantage of the improved emissions, lower price-per-gallon, and an increase in octane rating that effectively reduces engine heat and wear and improves horsepower. Dyno Test 100% Gas vs 10% Ethanol Gas. 0-liter engine and forced induction has become one of the most popular duos in the world of Ford performance. Fuel economy becomes like 15mpg though so you end up spending a lot more time at gas stations. Contrary to what most people say, mileage would not be effected much, maybe 10%. For example, on my pro charged TA with 7psi I only gained about 25 hp with e85 vs premium. The biggest advantage is that e85 has an insane oxygenation level, far better than the best race gas. "However, E85 (85% ethanol) and other fuels containing more than 15% ethanol must not be used in vehicles that were not designed for those fuels. Unless you've been hiding under a rock, you'll probably know that E85 is a fuel containing 85 per cent ethanol and 15 per cent gasoline. You might 'think' you feel a difference, but I've dyno'd fuel injected and direct injected vehicles and there is no difference without a tune. All done in a climate controlled dyno cell under reliable conditions. At Red Earth it’s at the pump $8.

C85 makes up to 4% more power and torque than conventional E85. com) The demand for a consistent ethanol/gas mixture is apparent and pump "e85" can have as much as at 20% variant either way (70%-90% ethanol) also all fuel grade ethanol is denatured with a very low octane cheap natural gasoline (86 or below). But that's pure ethanol, not E85. Many E85 fans tune their streeters on pump E85 for tooling around the streets and switch to a race E85 tune for the track. One Ethanol S is a fantastic product to bridge the gap between pump E85 and One Ethanol R. This primary usage of E85 does not take advantage of any of its potential performance advantages. 0L Coyote Dyno Test: CAI & E85 Tune Makes 532 HP. E85 fuel cleans the ports, combustions chamber and fuel system. With a very low Reid Vapor Pressure (a measure of the volatility of gasoline) it doesn’t turn into a vapor for burning easily, and required 24 degrees of spark advance. as far as simplicity, yes i had it tuned with E85, and it runs great. I started an Ethanol racing fuel company based out of Sacramento CA PRONOL Racing Fuel (pronolracingfuel. You've heard that E85 is all the rage at the pump, . Some racers report more power from E85 than from methanol. The purpose of this is to raise the Reid Vapor Pressure of the fuel for cold starts in flex. E85 will require significantly more fuel flow to achieve the proper AFR. Surpassing most other fuels, MRX02 is effective in delivering up to 7 percent more power than pump gas or any basic non-oxygenated race fuel. Fuel economy, E85 vs 87 gas vs 91/93 high octane gas. C16 is the slowest burning fuel of the bunch – but still king of the non-ethanol based race fuels. Plan is to break-in the engine, gather data for the 93 base, then tune for 93, then create the 100 octane, and then do the same for E85. This will give you a global of lets say -40%. The difference is that an E85 blend is designed with this in mind vs pure Ethanol. With use of E85 ethanol and appropriate tuning, we saw a net gain of 64 WHP & 38 WTQ over 93 octane gasoline! The gains do not stop there either. In drag racing they commonly use nitromethane in the top fuel dragsters, and years ago they added nitrous oxide. My thoughts or posts in this thread were aimed more at the increased MPG you get by running 100% gasoline vs a gas ethanol blend, and less about the octane you are running. HAHAV8 said: C16 is on a completely different level than E85. Currently E85 sells for around $2. Here is the 598 on 91 octane pump fuel + ACES IV. If you take a stock gas farm tractor & run it back to back on the dyno, only changing fuel from pump gas to 104 racing fuel to E85 you will see no significant power increase from pump to 104 & then unless it it was running extreemly rich on the gas, it will burn the pistons on the E85 from being lean. I'm sure that Phil or someone could chime in with the particulars of E85 vs. E85 will make more power than a traditional race fuel 110, 112 ect. However, there were some tradeoffs. For this reason, a number of companies have introduced E85 and E90 racing fuels that are blended to exact specifications. How much HP gain from 93 to e85, let's find out on the dyno! Stock vs 93 vs e85 with long tube headers on the 93 & e. It is around 10:1 as well and as a matter of fact the car picked up going down from 93.

Renegade Pro E85 is not blended with pump gas, it is made with premium race grade components and premium grade ethanol which produces high quality, consistent blend racing fuels that eliminates the need for testing and changing tune-ups. E85 is a combination of ethanol and low octane gasoline. Available in 5 gallon pails and 54 gallon drums. Unitronic strongly recommends the use of an Ethanol Content Analyzer, to ensure Ethanol content levels are within the permissible range. E85's cooling effect equals lower inlet temperatures, this added with its greater knock resistance allows racers to creep up boost levels higher than traditional gasoline blends. And It take energy, coal natural gas, oil, to make E85. Also the one part ethanol to two part gas ratio is easy to remember and easy to factor when I go to fill up the car (this assumes the ethanol pump is E85, not E70 or lower, so do test your fuel sources). One college did some testing on E85. my concerns are what will it do to the fuel system if it sets in the car. E85 has a higher octane rating (which is an anti-knock or "combustion under pressure" rating) than pump gas. I prefer to run E85 in my truck in order to get the horsepower boost from 355 to 380, especially when towing my travel trailer.

P600 Vs FK8 Turbocharger (Accord) While wildly popular (and for good reason), ethanol blended fuels do tax fuel systems harder to achieve the same power level as gasoline fuel. Since we have ethanol plants here, I can get E85 at just about every other gas station (about $1 cheaper than 87 at the moment). E85 is a fuel that is made of 85 % ethanol, and 15% gasoline. I do use a lot more of it than gasoline (approx 25% more at cruise and 35-40% more at WOT) but it seems to be a good alternative for me at this point (it runs 50 cents cheaper per gallon than pump premium gasoline octane and is $2 cheaper than race gasoline). At very high boost levels E85/E98 can be problematic and you can quite possibly still end up with knock occurring which at high specific power levels can very quickly destroy your engine. If you compare the performance of gasoline and E85, the latter undoubtedly produces more power. Quick Fuel E85 street & race carburetors have been dyno tested to produce optimum power and tested on numerous vehicles to validate calibration. The X85 module’s job is to command the fuel injectors to feed the car more fuel when it detects a higher blend of ethanol, as ethanol burns quicker than gasoline. Ignite Orange E85: The Ignite E85 blend is perfect for those with mid-range horsepower levels, crate motor applications, and carbureted applications. If I can find data that proves XX% of ethanol is best for power in a blown LS3 set up that's what I'll run. Normal gasoline contains toluene (2-3%)- some commercial racing fuel (100-105 octane), up to 25% + added lubricants. This fuel has certain advantageous attributes that make it a popular fuel for performance and racing. levels such as when running an Ethanol based fuel or race gas. Might have gained some back leaning it and taking timing out. XDI has two versions of the fuel pump; the 35% more capacity, 200bar/2900psi and the 60% more capacity, 250bar / 3625psi. E85, like race gas, is for those of us who are pushing cylinder pressures to the limit of detonation. What “potentially” makes it better than race gas is the price. E85 takes a lot more fuel system vs 110, . With a very low Reid Vapor Pressure (a measure of the volatility of gasoline) it doesn't turn into a vapor for burning easily, and required 24 degrees of spark advance. We picked up a tenth of a second and 2 to 3 miles per hour in the eighth mile after switching to E85 from 110 race gas and our engine runs 20 degrees. RACE-GAS ULTRA is a much different formula than original RACE-GAS. E-10 is 90% gasoline and 10% ethanol. When I ran 12 psi I gained about 55hp, again most of that is. 2015 Ingot Silver GT PP Beefcake Special Black Paxton 3. with a small block hi rpm combo-- if you took the same engine[ obvious jet change ] and ran back to back dyno test with each type fuel, . You run E85 until you are about out, then you run gas, or vice versa. This Tech Tuesday we’re doing an in-depth update to an old video. A motorist filling up and comparing the prices of regular gas and E85. So we went about getting this car set-up for Flex fuel and a new tune. In every case the fuel gauge on the dyno reads about double in #/hr burned and the A/F Ratio is about . Any glycol in the fuel is to inhibit any water it does contain from freezing. However, this quality and consistency come at a high price. Uses for E85 Because of the alcohol/gasoline mixture, E85 has a rough estimate octane rating of between 105-113 octane depending on the mixture. It DOES NOT have the same octane rating as 100 octane race gas. However, E85 has a 27% lower heating value than E0 gasoline, meaning you have to use more of it to get the same BTUs. The air/fuel ratio on the dyno meter read 11. Availble in 20 litre kegs, and 210 & 250 litre drums. Race gas?
