right now im at 11.2:1 compression....I wanted to get some opinions of the great ITR crowd about going to 13:1 compression and what type of power increase would i be feeling? thanks!

1) Is this your daily driver?

2) Is runing 103 octane a problem for you?

Well I run 12.5:1 CR on a daily driven ITR. If you have big enough cams, and the right tune it will run fine.....But I wouldn't go over 12.5:1 on 93. Pinging is always a problem with such high compression.
