Prototype Sprintex Supercharger Kit
Please read all the details on the sale of this kit before deciding to purchase it.
Comes with everything shown plus the longer belt which is not shown. I am also including a GM wiring harness pigtail for the intake temperature sensor that came installed in the manifold. The originally included exhaust header wrap is NOT included as it was cheap fiberglass wrap and had to be destroyed to remove it.

Intake manifold has the underside wrapped in DEI heat reflective aluminum tape. It has some red paint on the fuel rail mounting seats that came off the fuel rail. It can be picked with fingers or a brushing if desired.

I am leaving the brass pipe and vacuum fittings on the supercharger that I installed. They were not originally included and required a bit of tinkering to figure out how to run the vacuum lines.

Hardware has been sorted and taped together with blue painter's tape. A replacement manifold o-ring has been included.

Under 10 miles on all parts. $2,500 plus shipping; firm. I originally paid $3,000 plus shipping for this kit. Expect shipping to be expensive as the supercharger is heavy and the manifold requires additional padding; in the $100 to $200 range for the 48 continental United States.

Please be aware:
  • Not recommend at all for engines with increased displacement.(Strokers) This is why I am selling this kit.
  • This is NOT a bolt on kit for beginners. Sprintex provided dealer only instructions and you will need to be comfortable tearing apart the left side of the engine.
  • Exhaust header wrap is required. I recommend DEI's Titanium wrap and stainless steel pipe clamps.
  • Computer tuning and a 2 bar MAP is required.
  • It is your responsibility to double check supercharger oil level before running. The supercharger still contains the factory fill. Per Sprintex, "Use Redline 75W90 NS gear oil or equivalent. It is critical not to overfill gearbox as damage will occur. Fill with exactly 100 millilitres or 3.38 US fluid ounces."
  • It is possible to accidentally crush the supercharger to manifold o-ring when installing the supercharger. A new o-ring is included and I recommend contacting Sprintex to purchase spares for future servicing.
  • A custom fuel line from the frame hard line to the fuel rail may be required if you do not plan on using the seventh injector setup.

Painless 68mm 65301 Throttle Body
Gasket included. This is a really nice throttle body. Note: The aftermarket replacement IAC motor on my 1997 needed to a slightly different o-ring to work on this throttle body. I will include this o-ring in case you run into this issue. All the loose hardware has been removed and properly bagged since taking the pictures.

$400 shipped to the 48 continental United States.

There is already an interested buyer in the Sprintex kit. I am posting it here to be accountable for my sale and if the buyer decides to pass.
 
What kind of gains are we talking about on a stock engine?

Sprintex claims 275 horsepower at the crankshaft. Around an 85 horsepower increase.

Assuming non-ideal conditions on a stock engine running their stated maximum 6 PSI I would expect more around 250 to 260 horsepower at the crankshaft.

I would really recommend a water methanol injection setup to compliment this kit if it will be ran hard on hot 100ºF+ days.
