Default 10.5 Cr/ 18 psi/ E85

Thoughts on 10.5 cr with E85 and a alky control kit? Looking to be around 18psi with a procharger. Found a set of heads for a decent price that are 58cc. Looks like a -11cc pistons will put me around 10.4. Anyone else running higher compression with e85 and boost?

e85 you can run 11-11.5 compression with boost. I like to see a minimum of 10:1 on a boosted motor if its going to run e85.
We have a forged 370 with 10.7 compression with no intercooler and a TC78, kit spraying washer fluid just to knock down IATs and can run 14psi on it all day with no problems

Wish I had E85 in my area

10.5:1 will work nicely...especially if you spray some meth to help lower IAT's and combat knock

I have. 14lbs on a d1sc. Never skipped a beat. Ran with no meth for a while to. Then added meth and upped the timing a touch...

Not trying to hijack your thread but I had a question myself? How much boost on a forged bottom-end 383 running 11:1. Using the D1sc
