10.5:1 compression 408 with s91 turbo

would the compression be too high for a 10.5 :1 408/l92 setup on E85 with alky injection? i was 9:1 for pump and will be rebuilding. 20-22psi max.

Should work good long as the tune up is good. I just wouldn't get crazy with the boost with those heads. 14~15psi should make a ton of power...

You might not need alky.

Well in that case give it hell

The alky will still be a help, make more power, and help with distrubution.
