I rebuilt my stock 87 930 with 98mm mahle cylinders and RUF 7.5 to 1 pistons. The higher compression and the high displacement can easily be felt. There is a noticeable difference in the low end torque.
On the track there is a lot more acceleration coming out of the corners. I am running a max of .9 on the boost. My car also has a ring and pinon installed, but it has been on the car for years. The only drawback is the car runs a little hotter than it use to. I've never seen the temp gauge in the red, but on 95 deg days I have to come off the track before the end of a 20 min session.
