I havent red lined it yet...I really dont want to...but at 5 rpm I was at 115. I'm boosting at 14psi and have 391hp to the wheels so I figured I should get a higher speed. Plus it has a stage 3 ecu... I'm sure if I redlined I could get it to 130-140 but that's not going to be fun if something fucks up at redline haha
