Hey everyone, I know the stock 0-60 on an 03 GT is around 5.7. I have a 03 GT with a P1SC Procharger on it that makes about 320 hp to the tires (supposedly said by previous owner). Now mine is an auto, but I can only clock nothing lower than 5.4-6.0 sec on my 0-60 times. I'm using track addict app to time it, and it doesn't seem to make much sense to me how it could be any slower than stock. I was wondering if the autos are just that slow or should I actually be looking in to something being wrong that's putting me down on power.

Any suggestions or help would be appreciated.

 

Something is off somewhere. My 280 something (wheel) horsepower ( a guess) v6 (2011 automatic) does 0 to 60 in the low 5's with a lot of tire spin . With 320 wheel horsepower you should be complaining about traction problems

 

The P1SC car, even an automatic, should beat a stock GT all day long. Are you experiencing a lot of well spin? I do know that that particular transmission really bogs down on the 3rd to 4th upshift, but it should still beat a stocker, plus I would think 60 would come up long before that shift.

 

No wheelspin whatsoever, the car has 295's on the rear (granted they are all seasons) but the only time I can get the wheels to spin is when I footbrake it and do a burnout on purpose.

 

Thats what I'm confused about, the car seems to run just fine, but it is not doing 0-60 near what it should be.

 

I have Track Addict app that I use on the road track, and I notice that it is very dependent on the GPS signal, which sometimes is not very good. Sometimes it shows me going off the track, which I definitely did not do . . . . so I wonder if the data you are getting from the app is bad?

 

Well my GPS signal was good it said, and after I got like a 6.3 sec reading from the app, I timed it myself with a stopwatch, and it got about the same.
