Anyone on here bracket race and run E85 and notice car runs more consistent. Notice in when weather gets hotter car slows down which is normal but some runs intake may be hotter or little weather change and car slows down. I’ve heard people say when running E85 it’s not much of a change like pump gas. Evening thinking of making car run on E85 but don’t want to pay for new tune, injectors and fuel pump to find out it doesn’t really make much difference. And I’ve read on here where if tuned on E85 and fall/spring fuel is more E60-70 it still will run fine on the E85 tube just little more rich.

 

I run E85, and bracket race...and if that wasn't enough, it's a turbo car, lol.

Mine pretty much will run, all day/night, whatever it runs 1st pass. The only changes in ET/MPH are self inflicted with me & driver error.
My car will run easy 9's, but isn't NHRA legal to, so I run like 3-4# of boost, and a very lazy footbrake launch to slow it down into the 11's. That also helps keep my coolant and IAT down a bunch.

I do run a flex fuel sensor though, so my tune will adjust itself around any ethanol percentage variations.

I converted from gas only, about 2 and a half years ago. When I first started using E85, I was running N/A and used a 200 shot of nitrous, as my "scramble" button, or sandbagger equalizer near the traps.
Did my daily (Silverado) at same time. The car and the truck both run (& sound) noticeably smoother when I have at least 1/2 E-85 in their tanks.

 

Are you a seroius bracket guy. Like dialing to dead on? I have been bracket racing for several years. Been on E for the last 3. If I cant dial dead on I get frustrated.

My take gas and E are a wash. I use an ET prediction software. I believe the software works better at predicting on gas than it does on E.However E does move a little less than gas. I got tired of E picking up more than expected and moved to M1. For some reason as the weather gets better it will all of a sudden pick up 4 or 5 numbers. I have not been able to figure out why.
Also getting a batch of e90 one week and e85 the next makes it harder to get in tune with your car. 90 tends to move a little less than 85.

To answer your question. It is more consistant. As long as the weather dosent move alot.

 

I try to dial 1 above from what I think car is gonna run and usually works but ever once in a while it may slow up by 3 out of no where. Car usually runs consistent for the most part. But on gas it can pick up by .15 from mid day til night time. Was hoping that on e85 it would kinda stay a little closer though our whole day

 

Worth a shot to try. I have never moved a tenth during to day unless the air moved over 1500. So it might work for you.
