For sale is a used paxton centrifugal supercharger kit for 85, 86, and 87 TPI camaros, firebird formulas, and trans ams. This kit is out of production, but was a direct bolt on kit designed specifically for these cars. This kit could be used on an 88-92 car provided you swapped the accessories over (they are not included in the sale).
It could also be installed on most any SBC engine (or the 4.3 V6 engines) from the mid 70's up to the late 80's, as they all use similar accessories, but you would need to customize the install.
This kit is designed to produce 7 - 9 lbs of boost on a stock TPI 305 or 350 engine, which is good for approximately 50% more power than naturally aspirated. On a TPI 350, this kit should easily be good for 350 horsepower and near 500 ft-lbs of torque at the crankshaft.
I can assure you, you will feel a drastic difference driving.
My car went about a full second faster in the quarter mile with this installed, and that was with a severely slipping transmission (the extra power did not agree with it), and some belt slippage problems, not to mention a severe traction problem.
You will need to find a way to deliver extra fuel and/or adjust timing on your vehicle to compensate for the compressed air. Running any engine lean can cause damage.
Included is the instruction manual, and all parts needed to install, as well as a number of extra parts, as two sets of aluminum intake elbows (one with ribbing, one smooth with paxton text), extra connection tubing, etc.
This kit is a weekend install - it's much simpler than many other supercharger kits due to the simplicity of the kit, and the fact that you do not need to run engine oil into the charger. It uses it's own fluid, and includes a pump to cycle it, and it's own radiator. Also, much of the kit is still installed on my car, so if you want to purchase it, you're welcome to come and take pictures of the bracketry as I remove it to facilitate the install on your own car.
NOTE: Ideally I'd like to sell this in person, cash sale. I may potentially ship, but local buyers will be given first preference, unless you make it worth my while. It will most definitely not be an easy item to package properly and ship.
Free bump. Are those 3 individual belts or a single 3 groove v belt. I am asking becuase i have the exact same kit but i havnt bought the belt(s) yet. Any info on the belts would be appreciated. Good luck on the sale
Sorry, i'm not interested in just selling any intake elbows. I'd rather let the next owner decide which he would rather use.
Jay, I purchased this kit used myself, so I can't say about total mileage, but I've put less than 10,000 on it personally. the kit is in great shape, and the blower itself has tight bearings, etc, and it's always been parked filled with fluid.
As for the price - this seems to be going rate on this paxton kit as best I can tell. I paid roughly the same for it when I purchased it, and I've seen others go in the same ballpark.
Jay, i've seen other paxtons go for about the same.
Is there any way to change the pully on the kit so that it works with serpentine? I really want the kit, but I don't think I want to swap to an inferior accessory system.

toehead,
the supercharger and the pulley on the crank are separate belts altogether. you would not need to swap pulleys or belts to run with a serpentine setup. the reason this kit would not work on an 88-up is because the paxton sits right where the air conditioning compressor is. if you aren't running AC, or you don't mind removing it, it would probably not be too difficult to alter this kit to work on an 88-92 tpi car. or you could make or find a bracket to locate the supercharger to the driver's side of the engine bay. That's what the 88-92 kit does.
EDIT:
also, adding onto that, I don't know how familiar you are with the 87 model year stuff specifically, but if you look closely at my accessories in the pictures I posted, the alternator and water pump do use a multi-rib serpentine belt, and the higher amperage alternator of the later models. it's a crossover year. my power steering pump still uses a v-belt, and i'm not even sure what AC and the smog pump used honestly, i pulled them off the car so long ago. Either way, an 87 setup is not nearly as bad as 85 and 86 when compared to serpentine

86 and 87 use the same belt set up. My 86 has a multi rib serpentine belt and the rest of the system is v belt. just like your 87.

Curtis, I actually believe that's partially true. I think they switched over to the "87" setup sometime during the 86 model year. I personally have seen and worked on multiple 86's with the earlier setup, but yours isn't the first I've heard of that has the later setup either.
but yes, if someone did want to do an accessory swap to use this supercharger kit, the ideal way to go would be to find the later 86 and 87 kit

Hmm. Mines a very early 86 model (Augest) and its all original. The only thing I can think of, is the TPI cars and TBI cars had it. and Carbed cars had the old style v belt.
