I’m running corn in the summer. I’m sure a lot of combos work well, you’ll just need bigger injectors and potentially better pumps depending how much power you want to make.

I more interested in if people are using pump e85 and what their combo is on their car. Real world experience, not the general info.

I switched to a flex tune in October, LOVE the added power. Added a solid 5 mph to my 1/4 trap speeds, here’s dyno graph of 93 and e85. Negative is car guzzles the stuff but I’m never easy on it, I think my avg is like 7 mph. M6 even in this cold of Pa I’m doing mid 11’s on cold asphalt. Fuel system if I’d but again I’d really look at Steve White Motors dual 285 drop in set up tat still utilizes a fuel bucket around the pumps as 1/4 tank really needs to be treated like empty as far as aggressive driving goes as the fuel pickups do get uncovered leading to a loss of fuel pressure. Yes, I use it from the pump, all Sumer while I was testing if every few weeks deciding if I was going to try it or not, it tested 83-85% all summer, tested 2 weeks ago was 75%. I purchased a 55 gallon drum of e98 that I mix 50/50 with the 75 to get 85 but I think the 75 would fair just fine on it own.

E85 is like crack for your car.

I run a 2.79 for daily use on a flex fuel tune and a 2.50 on a more aggressive E85 only race tune.

I've ran both on pump 85 for almost 2 full seasons now. On the race tune I've found 75-80% ethanol (as tested via tube - not the car's reading) is the absolute lowest it'll tolerate.

I've had the full Dusterhoff stage 4 setup for 13k miles total so far. 0 issues that I havent caused myself. Curt is only ever 24hrs away and when we did need to make adjustments...from datalog to new tune during the week was 24hrs or less typically.

I use pump E-85 for street use. I test it every time I fill up. If car hits the dyno and track I use Torco 85. Soon might be egnite 90 for the track. Pushing 1100rwhp and 1010 torque right. 1700cc and a triple pump fuel system. Looking to push more power it’s always best to run better fuel when you smash the gas.

Presently myself with guidance from close friends who have been doing such for years but my car is a manual and the engine portion of tuning is MUCH simpler then auto’s are. Auto Trans tuning and matching such to the engine tune is a art best left to the pro’s for sure. My tune on e85 is mild at the moment, more tweaking is needed come spring and track days.

What are your goals? E85 in these cars has been done extensively just depends on what you're ultimately looking for.

I talked to Frank today. We talked about doing a 2.85 pulley and e85. I would like to be around 800-850 hp with good drivability on pump e85.

Ya typically a 2.85 on e85 will make around 830 to the tire. if you have any other questions let me know.
