Compression Ratio On E85

[iplen]

I've got a 4age 20v for a rally car, and if my Gtr stops breaking stuff I will be rebuilding it, I have had a quick search, but came up with various conflicting answers, so:

Given I cannot turbo it, just how much compression can I get away with? On 98 pump we were already running about 11.5 so the head design etc is clearly fairly good.

Any one that has gone this way, what issues have you had? More importantly, what results did you get!!?

Switch over now, should make more power

If it doesn't go for as much comp as you can without ruining the chamber squish.

Can you find anyone running methanol of the same type of motor, copy what they did but maybe back the comp off a little

Doesn't matter what you put in it, without a head it won't make squat I had only been search for general results, hadn't thought to be specific about a 4a, thanks for searching for me

Ive got a soft spot for 4AGE motors, I had a nice one in my old AW11, only ran on 98 though, still it loved to scream at high RPM.
