I am getting an 07 shelby gt and Im trying to get an idea of what to get? I have been around old shelbys forever and I dont want to do any visual upgrades to the car but I do want to pump out some more HP. what is the best for the money? I have been thinking about a nice kenne bell supercharger but I would like to get some feedback. Thanks
What cya gonna do with it? I bet you can get close to 700+ hp outta the 2 1/2 pipes on there now - throw on some axle backs to change the radio station a little bit but other than sound they should be good.
The stock short block won't last long at those horsepower levels. Keep it under 500 and it should last for years. Stock 4.6's have weak rods and the pistons don't like much detonation. Good luck.
