They're really not that quick. I had a p71 I put a trick flow upper plenum on, a bigger T.B, kooks longtubes, high flow cats, and midpipe... and got walked by an 05 jetta 1.8t with an Intake lol. From a roll or a dead stop... walked by the stupid Hitler mobile. So disappointing.
It sounded good, and did one hell of a burnout.. but certainly not a fast car. The P.I model vics only put about 215hp to the wheels from the factory.
They are super reliable though.. theres a reason every taxi in the states was a panther platform lol.
