Performance:

I ran the  dyno on 5/21/00 at Passen Motorsports in central Ohio.  I was a bit nervous, as my digital tachometer can't be trusted to provide reliable reading on the engine's rpm's.  I asked the guy running it to back off short of its peak, as I would rather have lower numbers than a blown engine.  (just a little overprotective, I guess)  So he did, and it provided the following numbers:

127HP   and   148fp torque at the wheels  -  Not bad for a 17 year old car with minimal engine mods so far..

The real performance is in the driving of this car, though.  It loves to chew up winding country roads!
