E85
How many of you are running e85 with boost? What's the combo and amount of boost and are you intercooled?

EFI, Turbo, air / water intercooler, 8 to 1 compression, been running up to 18 psi on the street with E85 for 3 years.
Lately the boost controller has been acting up and boost has been 25psi in and out of the throttle, engine is still just fine. |

Seems to me you really wouldn't need an intercooler with E85.

Under 15psi and carbureted with E85 I wouldn't worry about an intercooler unless you really plan on pushing it. Just my opinion. Hoping to log my IAT next year.

E85, 20PSI measured in the manifold below the hat injectors, and before the ports - about a 50/50 split.

Whipple charger - no intercooler. Yes that was my take-away too.

Timing and boost
Ok I are you guy running your timing locked out or are you pulling timing with a retard box gradually?

I control timing with a Power Grid, RPM based. With the positive displacement supercharger boost response, for practical purposes in my application, is instantaneous. Therefore I have no need to ramp versus boost rise. Your application could be different.
