A friend of mine knows a buddy who took a paxton super charger off of his 94 chevy truck. It's a 350..5.7 liter engine. Anyone know if this would work on my car? I think it would being they're the same engines maybe but i know nothing about superchargers.

 

The supercharger units are the same. Mounting brackets and piping are different. Stay away from old 'ball drive' paxton units.

 

how old and how do you know if its a ball unit?

 

Paxton NOVI is good with the gear drive.





Paxton SN series is the units to stay away from. They have the pulley in the center of the housing.

 

That sux. i am looking at buying one. i spent about 4 hours last nite reading and trying to find info on SN. i did see others talk about problems with paxton but don't recall specifics.

will you let me know what kind of problems they have, how often they occur and if anything can be done about it?

does it help if the unit is "new" i.e. never been used?

also, with 5-6lbs of pressure what kind of additional hp are we talking about? that being without a custom chip, just larger injector and higher volume fuel pump.

appreciated!!

 

Alot of info at www.superchargerhelp.com

 

It does not have a 'real' gearbox. It is built like a ball bearing. The outer ring (16) is fixed. The inner ring is connected to the impeller. By spinning the ball 'cage' (13) that is connected to the pulley the impeller is spinning faster than the pulley.

This works as long as the ball drive has enough friction. Once you transfer too much power to the impeller the ***** will start to slip on the inner or outer 'bearing surface' ... when they do, that ball drive is history and you have to buy one of these.

It is nothing you can do to improve the design.

 

thanks for the education.

so if i am understanding your point, this SC works ok on lower powered engines but does not work well on modified ones. i.e. it will spin the SC up to fast for the design.

well, you just saved me bucks and headaches.

what a shame i was dreaming of 525+hp.

 

Yes, As long as you are not using high boost or pushing lage volumes of air the ball drive works.

 

Another opinion I have it that the Paxton kit has a stupid piping lauout. Every bend is a restriction and a shorter radius is worse. The Paxton SN has a very tight 90 degree bend at the compressor outlet. To get to the throttle they have to add two tight 180 degree bends. That is a total of 450 degrees of tight bends in a very short distance.

(I found these pictuers on the forum)



Compare with the Vortech setup. That is more or less one 90 degree bend. Much straighter air path.

 

well, i passed it up. with your information it sure looks like the right choice.

while all the bends in the pipe have a detrimental effect on air flo it does look better than the vortec. shame they cannot dress the vortec up a bit.

thanks agian for the help!!
