itsblown93 Posted January 24, 2014 Report Share Posted January 24, 2014 I was wondering what's the highest compression that you can run safely with E85 and a turbo? I was think 10.0:1 or maybe 10.5:1. I'm planning on doing a higher compression turbo 2v motor. Link to comment Share on other sites More sharing options...
MaximumRisk Posted January 24, 2014 Report Share Posted January 24, 2014 there are a few variables that have to be taken into account, what is your power goal? what size turbo? displacement? Link to comment Share on other sites More sharing options...
itsblown93 Posted January 24, 2014 Author Report Share Posted January 24, 2014 power goals will be anywhere from 700-900. turbo will be 76mm-88mm. and the displacement will be stroked out to 302+ci Link to comment Share on other sites More sharing options...
WildWillyWalker Posted January 24, 2014 Report Share Posted January 24, 2014 modularfords.com bud. Quite a few of them are running e85. I mainly just read about 4v stuff though. Link to comment Share on other sites More sharing options...
Sleeperstang1994 Posted January 24, 2014 Report Share Posted January 24, 2014 as previously stated more information is needed. Dont let compression be the only factory hear. you have to keep in mind when you are going to be coming into boost and what temperatures are you going to be running in? are you willing to run meth with e85? Streetability? Link to comment Share on other sites More sharing options...
copmagnet Posted January 25, 2014 Report Share Posted January 25, 2014 There was an e85 2v on nodded mustangs with a 13:1 compression with an f1. Link to comment Share on other sites More sharing options...
blwnbyu Posted January 25, 2014 Report Share Posted January 25, 2014 The cams will be a huge determining factor Link to comment Share on other sites More sharing options...
Sleeperstang1994 Posted January 25, 2014 Report Share Posted January 25, 2014 There was an e85 2v on nodded mustangs with a 13:1 compression with an f1.its a balancing point. i imagine driveability has been severyly diminished Link to comment Share on other sites More sharing options...
01yellercobra Posted January 26, 2014 Report Share Posted January 26, 2014 its a balancing point. i imagine driveability has been severyly diminished<br /><br />Unless the cams were extremely big I bet the driveability improved. More compression gives better off boost throttle response and gives more low end torque before boost hits. That's why guys with centris are starting run 10:1 compression on pump gas.<br /><br /><br /><br />Misspelling brought to you by tapatalk<br /><br /> Link to comment Share on other sites More sharing options...

01yellercobra Posted January 26, 2014 Report Share Posted January 26, 2014 9.5 here.. be 10 on my new motor with meth<br /><br />My first round was 9:1. This time I went 9.5:1. I should've followed my gut and at least went with stock.<br /><br />Misspelling brought to you by tapatalk<br /><br /> Link to comment Share on other sites More sharing options...
