Probes Kit Rod
what is the best vortech supercharger for 99-04 pi mustang gt?
I have a 1996 Mustang gt. I have been building a motor for my car this past year and so far I have a 4.6L block bored .020, with a crank thats rated at about 600 hp (its not forged) with forged H-beam rods and Forged Probe pistons. I will soon be buying the 99-04 PI head kit. I have decided that the vortech supercharger is going to be the best for me (I wish I could afford a kenne bell but the price just seems out of the question) so my question is what vortech supercharger kit would get me around 450 hp. I see only one on American Muscle that gives around 405hp but that does not seem like a smart choice buying a supercharger from AM. Also with my bottom end what would be a safe psi to run,and i want the SC to really scream. I know I have a lot of questions; when it finally comes to buying a supercharger I really want it to be the right one. links would be awesome.
Note: running stock compression for 99-04 GT
There's nothing wrong with buying a supercharger from American Muscle. If the price is good it's a great choice. They're a huge Mustang supplier. Don't go by how much hp it says it will make. That is not a written in stone factual rating. Go by the size of the compressor and how much boost(psi) range it has. A smaller compressor will be working harder and spinning faster to produce the same amount of boost a larger one will. A medium sized compressor is advised for street use with a medium amount of hp over stock(about 100-200hp over).
You didn't mention the compression you're running. That's important. A supercharger needs relatively lower compression. If the compression is too high then you will fry the engine. And in general the more boost you run the greater the chance for doing major engine damage regardless of compression. If you have the bottom end to support it(ALL forged parts is recommended for supercharged applications especially at high hp levels) and you KNOW that the rebuild is absolutely perfect then running 10 psi is fine for the street. Any higher than that and you're pushing the limits of reliability and safety for your engine especially with a cast crank. They sell different pulleys to adjust the boost the compressor puts out so getting the right compressor is important.
Go on Summit Racing to get a better idea of what's out there. Also, go on the Vortech and Paxton websites to see what is actually made for your application. Then, do a general internet search to find the sites with the best deal while making sure they are a good reliable seller to buy from.
