THey have been proven to hold 1000rwhp....just not very long. I remember reading about a guy who ran his car for two seasons on 1000hp before he finally bent a stock rod. But that is VERY dependent on tune and TONS of other variables. I am just going to run these until I blow it up, then have my built motor ready to swap in.

I do have some JE pistons, but the rods are the weak link, not the pistons. I did however use ARP rod bolts, but again, the actual ROD is the weakest part of the stock 2J motor IF you don't detonate. I only added the pistons to pevent breaking due to detonation. The pistons are actually hurting me HP wide and I would have run more with less boost on stock pistons. Car sounded 100% better with the High compression too. The original #6 had some pitting from a foreign object so I just replaced them all with spare USED parts I had laying around.

Higher compression. Better thermal efficiency. Boost would aslo come on much sooner.
I remember the first time I started my car with the X-trim wheel and 272's on 9.3:1. It sounded awsome. The pressure coming from the exhaust was insane even at idle. I had to pull the motor apart shortly after that due to a BHG(from welding on head and not resurfacing) and put it back together with the 8.5:1 pistons. So now I am at like 8.3:1 and possibly lower. The exhaust not is VERY LAZY now and doesn't sound near as good.
My race motor will be 11.5:1.
