Up for sale is a recently rebuilt Comptech whipple supercharger (CTSC) kit off of my 91. It includes both 9psi and 6.5psi pulleys and made 392whp on my car at 9psi. This is a very complete kit including install manual and all hardware, all you need is engine management. $7500 plus shipping
The supercharger itself was rebuilt in April / May 2023 by Jon Bond performance. Both rotors were replaced and coated, all bearings replaced, etc. It has roughly 500 miles on the rebuild and it has 0 miles since its last visit to the rebuilder in Oct 2024 where they disassembled, inspected, cleaned and re powdercoated the case (see rebuild note below for details). Note that the rotors did graze the case at some point after the initial rebuild, there are scratches in the rotor coating, see the pic below. This is unfortunate but only cosmetic. On the last visit to the Jon Bond, they felt that the scratches did not impact how the blower functions at all, and it still made ~9psi on the car
It comes with:
Rebuild note: In Oct 2024 it went back to the rebuilder as they forgot to drill a vent hole in the case. This caused it to weep a very small amount of oil out of the drive snout bearing. They fixed it, and in this trip it was also re-powdercoated, cleaned, and the mounting face was decked. They noted the scratches on the rotors and decided they did not impact the functioning of the blower so did not re-coat the rotors. It is fresh and has not been installed since the Oct 2024 visit.
