I just finished tuning my first PTK turbo kit on a 99 mustang GT 4.6 2v.. She uses a Garrett GT40 50 trim turbo @9lbs boost, 42lb squirters, and a lightning MAF. The only other modification that i did was enlarge the turbo inlet piping from 3.5" to 4" to match the MAF. The engine is COMPLETELY stock. The tune is very conservative (11.6 a/f ratio 16 degrees total timing) for engine longevity.
In comparison, the typical centrifical supercharger @ 8lbs on the same car nets 330-350rwhp, and 350-370rwtq on tecmotion's md600 dyno.
After tuning the car on the md600, i took her over to concept1 to spin the rollers on a dynojet to get a comparison. There's a 14.3% difference on hp, but no accurate torque #'s, as it maxed out their dyno at 500rwtq.
We overlayed the dyno curves over a 7.3 powerstroke diesel f250, and the mustang made 100rwhp and 30rwtq more that the truck...
Kinda makes me want to sell my novi1000.....

Just a minor correction, assuming you are talking about the overlay I provided, it was against a 2003 6.0L Powerstroke, and I'm pretty sure that the truck made 30 ft-lbs more than the car, but it was pretty darned close, and considering the ultra-conservative tune on the car, I wouldn't be surprised to see it equal or even best the 6.0L Powerstroke!

I do have to say that this car makes me think really hard about a turbo project.
