I couldn't see much difference in the actual supercharger setup other than a ratio change for the drive of the supercharger, so that extra $8 000 went into the drive line.This 1988 Ford Thunderbird Turbo Coupe shows 9,400 miles and is finished in black over a red cloth interior. My vehicle weighs roughly the same as a full size pickup and the 400'ish hp I have is sufficient, I had little use for another 100 let alone 250hp. The Stage One had no drive line changes, but the Stage Two had drive line modifications. The first was a paltry 100hp to the wheels (12 000AUD)and the second was 250hp to the wheels ($20 000 (engine didn't rev harder so torque was significantly increased)). Harrop offered two stages of performance.

I looked at a Harrop supercharger for my vehicle.
