Just like the topic says has anyone boosted their g up to 15psi. All I've seen is up to 8 psi. And pushing out around 400 to 450 whp. I'm about to boosted mines up to 15psi and was wondering what kind of problems if any are u guys having.

If your block isn't built for the higher boost levels, you might as well kiss it good-bye now. The reason you see the low boost numbers is because that is all the reliability you are going to get on a stock block.

plenty of people have boosted that high but with forged rods, pistons valves, springs, etc

Just gotta build it and it'll do just fine.
