GMC Syclone Prototype Number 15 has PAS 001 on the side windows and the front of the rear-view mirror.

INTERIOR:
  • Center console is a yellow color, made out of a prototyping plastic
  • Syclone seats with embroidered logo
  • The interior carpeting is still the 4×4 carpet, with the hole in the carpet for the 4×4 shifter.
  • It does not have the Sunbird Turbo dash, instead it has some other Pontiac dash.
  • It has a turbo gauge, tach, 140mph speedo, and all the other things.
  • SLE badge on the glovebox door
ENGINE:

The engine is basically that of a stock Syclone, with a few exceptions:

  • The cam is slightly larger, the pistons are from a turbo 350, and the turbo is a Garret, instead of Mitsubishi.
  • The intercooler is all custom, built by Garret.
  • The ECM sits in the glove box, and is entirely custom. It can be reprogrammed on the fly, using a laptop computer
  • The chip stores “defaults” and can be replaced

The engine has been modified from PAS from its original form. It is believed that the intake, turbo, and intercooler have been replaced with semi ‘stock’ parts. The originals are believed to be in Marty McGuire’s possession.

EXTERIOR:
  • The vehicle does not have any ground effects and has S-15 steel bumpers.
  • There is an estimated 350 lb weight welded to the rear bumper to keep the rear end down while pulling a Towing Dyno.
  • In the bed of the truck there is a gas cooler box. This cools the gas using NOS.
  • SLE badge on the cab
  • Production Syclone rims and center caps
DRIVETRAIN:
  • The transfer case came out of the AWD GMC Astro van, the front propshaft was developed at GKN in Auburn Hills, Michigan.
  • The front differential is not that of a Bravada, it is a normal 4×4 diff, that has had the shift mechanisms removed.

We believe this truck was donated to a church group, which then raffled the truck off.
