So I was using 100 octane fuel with 720/1300. I made 378 @ about 17 psi. Since then I've thrashed my turbo and now using a GT35 with .82 ar hotside and just picked up 2 ID2000 for my sec. I'm heading out to get retuned within a couple weeks. I'm thinking of switching it up since 100 octane runs about $9-10/gal. I'm expecting something in the low 400s. This car is my designated drift **** and won't see the road cause I live in commy California. What can you suggest? E85? Stick with my 100 octane? Any help suggestion are much appreciated

 

if you can run E85 it would be a good move as road racing/drifting is the most difficult challenge for our small yet powerful engines. heat cumulates and you are running a smallish turbo w a small hotside. this creates both higher intake air temps and higher retained exhaust into the intake phase for the motor.

alcohol is the heat destroyer. while there are associated costs, the cost of melted motors from gasoline is also real.

your only other option would be gas w a very good water meth system.

Thanks for the input. Looks like E85 it is. Now if I run E85 on my current tune with 100 octane, will the motor still start and idle? I'm just looking at how much tuning will be needed.

 

At minmum I would suggest moving the 1300cc to the primary and ID2000cc secondary. The tune will change quite a bit it should start on but of course the fuel map is going to change. Usually E85 consumes 30% more fuel...
