Not really. The car and the Paxton installation Joe was talking about were not stock. Forged pistons,Vec II - done before he changed the pulley. It was surprising to me that the stock Paxton fuel system held up at this HP level. I still think an AEM install with a better fuel system would be the better, and safer, way to go at the HP levels mentioned. I'd like to see how the car Joe mentions performs under varying outside temperatures. It is clear from Joe's post that these numbers are not safely obtainable with the stock pistons.
"I am posting this for people wondering what a paxton set on kill would do to a semi stock SRT 10. This is a 05 srt with a set of forged pistons, cat back exhaust,and a vec 2. Everything else is stock...heads, cam, manifolds, cats...etc. I tuned the car a year or so ago and it made 726 to the wheels...I thought that was pretty good, well add a 3.25 pulley and watch out. I added the pulley and used 93 octane fuel with no other adders (water/**** or nitrous)and made 866 and 812 to the wheels. I have a very mild tune in the car and there is more left, but the stock/paxton fuel system is maxed out. I think with a 255 in the tank with a return and a regulator this car can make over 900 easy. Here is the dyno sheet for now, we will see what happens in the morning.
See ya,
Joe"
