I have a 05 saleen it has a saleen supercharger on it running 3.4 pulley 8.6 of boost.It makes 480 to rear wheels can i go to 11 of boost on stock bottem end.How much is safe.

 

from what i see alot of guys are running 450-500rwhp on stock 3v bottom ends.

 

no, you are around the max HP before your motor will go bye bye. unless the saleens are forged in anyway over the gt's.

 

buy a forged shortblock from one of the 3v specialists before you bump the boost any. You'll probably find a few people running 11-14lbs on a stock bottom end. Those same guys aren't shy about slapping a new block in. Remember... there's just getting away with it and then there's having it reliable.

realistically.. you're making about as much power as is useful on the street.
