Okay, I've stated before that I'm pretty new here to the Charger website because I'm in the process of selling my 01 mustang to get an SRT8 charger. BUT, I have been doing quite a bit of research and trying to put some things together. I'm hoping maybe you seasoned dodge guys can help me. GS motorsports has the 6.1 supercharger kit and states that it gets 500 to the wheels and 507 pounds of torque with the 6psi kit. I know on mustangs...if you pretty much JUST get like a 6 pound kit and tune it right (plus throw on the aftercooler) they run pretty safe for years with no bottom end mods. Now I know the SRT8 has all the urgraded rods, pistons and a forged crank shaft AND the intercooler. BUT, it's already rated at 425 (probably 375 or so RWHP) and so it's got quite a bit of pressure on it where a stock mustang even with a 6psi iboost is only getting about 330 to the tires. Quite a difference in the the engine power before you put the supercharger on it for this SRT8. So, if I put this 6.1 kit on my SRT8, will it hold up without blowing a piston? Is this SRT8 upgrade able to handle that? One of the biggest concerns for me is that the pistons are rated at like 10 to 1 compression...that's pretty high compression and ANY boost on an application like that is usually kind of dangerous. If I don't use any more than the 6psi kit will the car hold up without any problems? Normally an SRT version (for mustangs it's the SVT Cobras) are set up to hold up to more boost and abuse than the RT (GT models for mustangs). I don't see anything on GS motorsport that really talks about whether they've had problems with the kit not holding up with the 6psi. 6psi is plenty for me...I don't need any more than 500 around here. That's what my mustang is pushing right now and so far not much around here can take it in a red light to red light or top end race. Oh, and another thing...anyone know anywhere in the GA area where I can get the supercharger installed? Not too many people around here familiar with Dodge's that much...mostly just chevy's and Fords. Oh, sorry...one more thing..does this 6.1 kit come already tuned? So all you do is drop it in the car and drive it off or does it NEED to be tuned after install? Sorry about all the questions but after the problems I had with my mustang I want to get this right. Thanks again.
