I should restate that with the V8's obviously dropping the compression ratio and new pistons and rods there are some pushing 10-15 pound range... of course more with intercooling... as most know there is NO room to add to much under that hood...
Depending on the heat in in Southern CA I generally am making anywhere from 480 - 522 horses.
A couple folks have asked how I've made the transistion , I still have the Vette, but LOVE my Xfire and look forward to growing with the market and the car as well... it is quite snappy!
