This kit was originally designed for the LS1 GTO platform from Magnacharger. Magnacharger never offered a 4th gen F-body kit due to clearance issues with the cowl. However, I have seen a few people install them on 4th gen F-bodies with some modifications. The belt drive accessories will line up for either platform. It will not work on the corvette or truck front accessories. This kit will come complete as it does from Magnacharger minus the crank pinning kit. It has the complete blower unit, 46lbs green top injectors, front mount heat exchanger, pump and tank. Also included is the upgraded HD tensioner and belt.
This kit currently has about 8K miles on it. When I ordered it, I had a couple upgrades installed on it. The rear drive pulleys were changed to a 1:1 ratio. This allows a larger front pulley to be run to eliminate belt slip. It works really well. I have never experienced any slip. Also, it includes a $600 custom billet Nick Williams throttle body. The throttle body uses a remote mount IAC valve. By doing this, you gain some extra hood clearance. This unit fits under the stock hood of my IROC.
On my bone stock LS1 motor, this blower made about 6.5lbs of boost and produced 440hp/441tq through a 6 speed and a ford 9” rear. While the peak power numbers are on the low side, the real benefit to these style blowers is all the low end power you gain under the curve. The motor made over 420lbs/tq starting at 2500rpm which makes for a very fun street car.
The only reason I am selling this is so I can try a new form of forced induction power.
This unit is in next to new condition. If you were to buy this new, it would cost around $6500. I’m looking for $4200 plus shipping from 49331 (MI)
This was what it looked like brand new out of the box.
Is there a way to increase boost? Wouldn't numbers improve with better heads and cam? I'm sure Thay would. Let me know if anybody you has done these mods with one. Thanks
