Some people have smoked the pistons on a stock 03-04 cobra due to tight wall clearance. It is all in what you want. My wife can tell yuou that my car is my baby. But I want more. This is a chance that I am taking. Right now I have 513 RWHP & 484 RWTQ. This was done with a Steg. Stage 4 port and 2.8 upper.
Also, NO matter what anybody tells you, IT IS IN THE TUNE. If your tune sucks, the you run the chance of blowing up your car. I went with another fellow 03 cobra owner to a dyno to get our a/f check and whe he found out his car made 40 RWHP less then mine he got a bit mad. We both had the same set-up's, but he lost the 40 in his side pipes.
He had the guy at the dyno mess with his tune and after he got it off the dyno, he could not start it. Then on the way home, the fan's quit working and it overheated. He kept having the problem until he had the computer replaced. But it all started when the guy at the dyno messed with his tune. You can ask U1arunit about this.
So if you are willing to take that chance, just make sure you have all the supporting mods and a GREAT TUNER. I have learned a lot by asking the guys have done the mods. This is how I make up my mind on what I want to do. If you are unsure, just ask before you do.
Just remeber, it is all in fun & there will always be someone faster then you. Jeff and Mark are faster then me, but I am playing catch-up.....![]()
