I took off the exhaust side of the turbo and am going to add a pulley on the other side. I am trying to figure out if it will spin fast enough to generate enough boost and how much? Please, if somebody has insight on this, please let me know.

Dyno Numbers
My best dyno was 253 HP and 304 torque; however, I had them graph it with the STD HP/Torque option which I understand is less accurate than SAE. I'm going back on Thursday for a second dyno session. I'll ask them to do a SAE graph next time. I'll attach the graph once I figure how to.

I bought the kit from another site member. He originally purchased the kit from the following company:
Need For Speed
1936-A Sherwood Street
Clearwater Florida 33765
727-539-7733
My final dyno numbers are 280 RWHP and 316 rear wheel torgue.

Hi all. Ive been away for a while. Ive made a change to my twin supercharger idea. Im only running a single. Im almost complete with the supercharger. I am using a planetary gear box from a warn winch and running it in reverse and using only the first stage. Im still curious how it will turn out. If my math is correct just the first stage planetary should spin the impeller at a rediculous speed. I guess well have to see what happens. Stay tuned for more.

It's possible, but a Ford Cobra puts out 390 HP and 390 torque at the flywheel. If you managed to beat a Cobra, I'd pay money to see the look on the driver's face.

Well, Im a little edgy as far as using the gear drive. It seems to work the way I expect it to, but its a little choppy, but that could be because nothing is completley connected yet. I also decided on an optional reduction gear box utilizing a 5" pulley and an 1 and 1/2" pulley. If this works the way I hope, it should spin anywhere between 20-and 50000 rpms. The bonus to that is its way cheaper to replace the belt and it uses ball bearings for smoothness and an open gear box for cooling. I saw a similar design on the gator supercharger setup. Either way I will still save the planetary gearbox for possible switch or other superchargers. Hey check out my album, I added more pictures. Till soon.

Oh, by the way, the 390 HP you mention is a conservitive figure given by the factory. I know for a fact that a 2003 Cobra will put out over 410 HP on the dyno un modified. I saw it almost four years ago. Sorry didnt want to step on your tail.

to all you guys and girls out there who want to add a supercharger to your 4.2l you better do some internal work to your motor as well oh dont add a superccharger to a motor with alot of miles on it and it better be in good running condition for starters you will need a higher capacity fuel pump 255lph is a great start headres a re a must a camshaft is also a must a bigger throttle body a bonus and you better add at least 24#hr if not 30#hr fuel injectors a mass air meter for the extra air delivery 85mm works great and a flash burner to calibrate your fuel curve you mass air meter and your fuel injectors ill give you the names of the manufacturers also to help you all out
jba makes the headers fordmotorsports makes the injectors need for speed has the supercharger kit bbk had the throttle body and fuel pump rpm_mustangs has the camshaft and rollerrockers sctflash has the flash burner and you better use a copper cored spark plug with around .35 to .45 air gap any other questions just post one
