compression ratios
Monday, May 25, 2015 9:00 AM
Hey guys, I'm currently running a .020 forged motor with the Hahn 20g stage 2 setup. I'm about to pull her apart for some freshening up and I'm thinking about bumping my pistons up from 8.9:1 to 10.1:1. I'm also wanting to go with a much bigger turbo too. I'm also switching over to e85 fuel. Do you think this is too much compression for 25+psi or do you think it should be fine? I know a bunch of ricers in my area with 10.1:1 pistons but I'm just about the only ecotec around besides a few cobalts on stock internals with turbos so I have nothing to go on. Any input would be much appreciated. I guess I should talked to wiseco or diamond pistons also and get their input. Thanks

WHAT DO YOU MEAN I NEED TO TUNE MY CAR?

As long as it can be tuned well you won't regret raising the compression.
