i know headers, chip, intake, and exhaust is worth the cash but are pullies, fan, ignition system, and tb spacers really worth it?? does the cash i lay down for these on another truck really get a bang for my buck???
The pullies and fan will help your bottom end. The throttle body helps from about 2400 RPM and up, try to find one used. The ignition depends on the mods to your engine - e.g., supercharger, NO vs normally aspirated.
It was the first SC for the +98 S-trucks and I installed the Wynjammer in 1999. It's similar to the Powerdyne in that there is no oil line and mounts on the left side with no drive accessory relocation. It's about a 6 lb SC with a bypass valve and boost gauge - runs fine. I will probably go to a smaller pulley shortly. They are no longer in business because Powerdyne decided to sue them.
