How much boost are some of you guys running on E85 and how aggressive are you going on timing? Thanks

With alky?

Yes, I am spraying Meth (dual nozzles) to add fuel because I only have 65# injectors. The Meth/E-85 mix works great for my car. I NEVER get any knock retard like I used to with just Meth and 91 octane (at only 24PSI).
Also, I just ran my car through emissions down here with a E-85 mix and no cat and it had no problem passing.

I am going to run E85 and dual M15 nozzles as well. Do you think E85 meth combo is as good as running E98?

Not sure who crispy chicken is, but I may know. Anyway, I just heard of a guy here in town who was running 35 psi plus with a 70mm turbo on e-85.

This is an old thread but I thought id dig it up and see how things have progressed in the e85 tuning world.
Where are you guys at these days with your boost/timing/afrs? Im at 24psi / 23.5deg timing with 10.5 afr and it loves it. Care to share?
