In reference to the inconsistency. For us south east coast guys we don't have to worry so much about e85 "winter" "summer" blend.The whole year is always winter blend for florida and the southeast US.
I can't find the thread but it has the dates listed for when the blends of e85 change.

From what I know about e85, good fuel lines is recommended and a strong high flowing fuel system is needed. Because the gas burns cooler you can run more timing meaning "faster spool" and more Psi. although you need more of the fuel to run the same numbers as q16 or c16 it's still the preferred option for a lot of tuners.

I would be happy around 400+/-

I am huge into autox and looking this summer to start taking classes to get my HPDE racing license. So i dont want a crazy amount of power.

 

Ive seen numbers close to 500 with e85 the right tune and all stock parts including head gasket. I reacently moved from MN and 35% of all tuners there run it all the time.Ive seen 3 ap1 and 2 ap2 that DD and run e85 with no problem. I am in the process of tuning my ap1 on e85 only bc my scion tc was and produced better results then i could have ever imagined. The guys at Full Blown Motorports in apple valley MN do it all the time with constant good results. Here in ND e85 is quite common and alot of subaru and evo guys have made the swich

 

^ 567whp with E85 18psi tuned by Fullblown Motorsports stock engine. Yes E85 is great stuff and I run it all the time in the summer. E85 is harder to start in the winter time and that is why they switch to E70 blend.

 

You shouldn't even be considering E85. Just get the used ID720 injectors that AngerMan has for sale, get a walbro 255 fuel pump, your choice of EMS, and you will be all set.

 

Wat? HPDE is not racing. Either you meant Club Racing license (unlikely as you need a fully caged car) or a Time Trial license which requires making it through HPDE levels. Or you meant racing school like Skip Barber to get your Club Racing license so you can do HPDE at higher levels in your own car.

If you're heavy into autocross, let me tell you not to go supercharged. Buy suspension and a diff and go STR. Your wallet will thank you.

 

Sorry thats what i meant going through the 4 levels to do time trials. I cant race STR im stuck in BSP becuase i made the choice of modifying the head with supertech valvetrain a couple years back when i floated a valve. BSP is a hard class and dont think moving into SSM is going to be any better. Really just want to move on and try something else like HPDE, Plus i have always hoped to SC the S and now i have the chance, got to try it atleast once.
