I was seeing 14psi with 9.3 compression and pump gas. 8:1 will be a dog until you get into lots of boost. You have a centrifigual sc so you need the compression till you get into some decent boost. There are no issues with higher compression as long as you have a good tune
Mine is by no means a dog with 8:1. On the street it is very powerful with 1/2 throttle. Full throttle is non existent on the street.

ok maybe dog was the wrong term but the idea behind low compression pistons in boosted aplicatons is starting to change. Twin screw or roots style blowers are a different situation.

especially if you have aluminum heads since they decrease the chances of detonation.
True, I don't mind the extra safety margin. I will give up a few HP for that.

Its all in the tune. Chris got mine done in no time once the little bugs were worked out. Only took him about an hour to get my meth tune done and not much more for my tune without meth. Its sweet to have a good tuner that less than 2 hours away.
True, did pretty good job with mine and Amber. Only took about an hour to get Amber done.
