He claims 330hp

$ 7 000 CDN tops.... :?

Mods dont really affect the KBB or black book value at all

hmm, not bad I quess... hows his questimate on hp? way off base???

No not way off...bout 300 -330hp....at the engine not wheels.

-Magnuson Supercharger Nose drive assembally NO GAIN
-Good-year Gator-back belt NO GAIN
-Catalytic converter removed NO GAIN (maybe 5 tops)
-Replaced with a off-road pipe/O2 simulator NO GAIN
-Borla dual 2" round pipes NO GAIN
-After market ECU WHAT ECU?
-ACDelco Platinum plugs NO GAIN
-Accel 8.5mm Performance plug wires NO GAIN


I agree, the other mods might make 300 hp at the crank, but not the wheels.

I do not think he could be that high up there with the HP. I estimate a tad under 300 at the crank. All he really has are headers, 3.25 pulley, intake and exhaust. I really doubt he could get to 330.

The pulley and headers are a good combo. The exhaust on the GP isn't so hot, i'm assuming he has a U bend removal as well. I'd say around 300, but his torque is much better now.

His torque would probably go down do to the race pipe, and no cat.

Not on a blown 3800 with a pulley upgrade.

Hmm, so with a muffler and downpipe upgrade, does not having a cat boost performance? On a blown 3800, that is.
