Looks nice, I think he'd be better off putting it back to stock and selling off all the parts seperately.

223 is ok but why not turbo? I never understand that.

 

$15,475?
Bwhahaha, you can get a 3rd gen + mod it some for that price!

 

my 12 second FD was only $11.5k

 

THe supercharger gives you more low end torque and responds instantly when you press the gas pedal since it's belt driven. It's the best streetable increase in performance as it makes the engine feel bigger/more powerful (vs a boost above 3500 rpms).

I'd imagine it would do better in the parkinglot and autocross races.

Keep in mind the GTU is a great sport car to start with a the supercharger makes it a supercar

His GTU-S is even better (and rarer).

I was thinking of adding a supercharger to a converitble setup and swapping in the TII gearing and transmission.

 

That horsepower is at the wheels. So, if you assume 20% power loss through the drivetrain, it's pushing about 278 at the flywheel. For a car that only had 160 at the flywheel to begin with that's pretty good, it's a 75% increase in power.

 

That car has been up for sale forever. I like it though. Don't know about the price seems awfully high.

 

Yeah for that price you'd think it would be a Mariah rx-7 conversion or 3 rotor.
