yo! new3 here but been around the block with my fords. but still i have never supercharged a car. i have a 2002 gt 4.6 2v looking to supercharge it ASAP cant decide wether to go kenne bell, procharger, or vortec??? also ont know if a supercharge would be safe with all stock internal engine components. any ideas??
2002 mustang gt: underdrive pulleys, 75mm plenum, 75mm throttle body, 90mm mass air, 24lb injectors, maccold air,diablosport custom tune, bbk headers, upr off road x-pipe, slp loudmouth catback, pro 5.0 short shifter, 3.90 gears, alunimum driveshaft, steeda springs, sub frame connectors
guys supercharge them all the time...they tune them to around 390rwhp which is a safe tune for your internals...your probly going to make the same amount of h/p no mater what supercharger you pick. by the way nice times!
i like procharger. all three are good superchargers. with a procharger you do not have to tap your oil pan, and they offer a nice 3 core intercooler which is not like the water to air like vortec has. but that is just my opinion. kenne bell is expensive and over rated IMO. everyone says ahhhhh kenne bell!!! because they see all the KB cobra videos online.

i have a vortech and quite a few other people on this forum also. now most have their opinions on which is the best. ima break it down for you. the KB is a great blower. makes good power, but unless you have the suspension and tires to support you gonna basically spin all day long. a vortech, procharger, or paxton are great DD blowers that are very similar to turbos. we call em centrifugal blowers. with my vortech i didnt lose any gas mileage on the highway, and about 2 mpg in the city when out of boost, when in boost it gets into the single digits. i paid just a bit over 4000 for my entire Vortech kit, which included everything from the powerpipe, fuel pump, spark plugs etc. and that also included installation, good luck getting that done with a new KB. IMO your better off with a centri blower, any will do, and just go with what your wallet will provide.
and by the way your rods and pistons begin to fail at around 450rwhp depending on your motor, but i have seen many 2vs go over that on the stock bottom end and have no problems. just beware that when you get close to the 450rwhp mark something could fail
I prefer the instant torque and waaaaaaaaaaaay cleaner lookof a KB myself. The banshee wail at full boost is the icing on the cake. Centri's sound like *** to me, almost like a idler with a toasted bearing.

ooh but KB puts out sick numbers, but youll definitely need more than just that blower to go fast, youll need a buitl suspension and sticky tires. i break my tires loose in 2nd and 3rd, and mines not instant. i can only imagine the KB boost. theyre both great both ill take a centri
I use a Procharger PSC1 with 3-core intercooler. I like the self-cooled approach Procharger takes. No issue with the other brands; they're fine. With a 12 lb pulley and forged internals (H-rods, pistons, crank)42lb injectors, Bullitt intake, MSD ignition, chip tune, headers, some head work, etc. you can make over 500rwhp. I tried it with stock internals and it exploded like a bomb. Forced induction will get you into detonation territory and stock internals will not last if you boost much at all. I'm busy re-building with the forged parts mentioned above.
but costs more and takes more to get to the ground
If you add up everything you get with KB kit its a good value for example new aluminum intake, boost a pump, a reliably tuned chip. Basically everything you need minus sprk plugs, antifreeze and guages.
9 psi is the most on stock internals. should get u up to bout 425 horses. 2 valves are wimpy i realize it more everyday. invest in a 460 stoke it to a 477.
Not really .. it depends on the blower .. TUNE .. intercooled .. non intercooled etc ... really what you need to be concerned with is what are you building the car to do .. and what are you power goals ... then you can start breaking down weather you wanna go twin screw centri or turbo .. $ and supporting mods all play a roll in the decision ...
good point then, what if i just want a bad *** street stang and on the trak side i want respectable numbers. but mainly just street. also, instead of a charger should i just build the motor for the same price???i dont know.
