I'm doing a n/a build and one of the things I'm looking to do is increase the RPM range. I'll be possibly looking into shimless buckets, knife edging the crank, some porting, and itbs. Not sure how much of this will actually make it into the car but it's all on the list of wants. I'm not trying to increase the rpm range just because, I'd like it to be useful. So I suppose my question is who has done mods to move past the 7.5 redline and were they able to get any benefits from it.
