:lol:i was at the shop the other day when a buddy of mine just happend to show up and put his car on the dyno because he want more power. he has a stock gsr in there now and i sware he wants to blow it up before he puts in his built motor because they straped his car up and took it to 11psi and were at 327whp when i went back up front and they were still adjusting the timing before i left ahh those crazy tunnerspsi doesnt mean that much. your whp is what matters. a stock gsr block can take about 300-320whp if tuned properly. obvioiusly if you beat on it everyday, that will shorten the time it will last. if you want it to last a really long time, keep it around 250-270.
