HPP Racing Tuned my car

[davidsk5018]

I drove to HPP racing in Lewisville, Texas to have my car tuned and my dry kit converted to a wet kit on Thursday and also spent Friday there have some issues worked out. While on the dyno, among other problems, they noticed the car was going lean, and the voltage was also dropping. The alternator had to be replaced, and along with putting an overdrive pulley on, it should be good now. I would recommend that for anyone using a smaller pulley. Lesson learned. In short, the guys at HPP did an awesome job, the coolest guys I have met in a while.

I just wanted to let everyone know that the HPP guys know their stuff for the 03/04 cobras.

Nice numbers. That will be a blast to drive.

Just for future reference, were you using a 3.2" with your 4# lower or the OEM?

The 3.2" alt/4# combo will underspin the alt by 8% (versus all OEM) and the OEM alt/4# will overspin the alt by 13%. Based on your comments, you probably had a 3.2" and went back to OEM (2.6") to get higher alt speeds.

BTW, I think you have the alt pulley size backwards...smaller makes the alt spin faster (overdrives the alt).

The upper is a 2.8, the alternator pulley was OEM. I now have a larger pulley on it to keep it from overspinning. Sorry, I did get it backwards.

Sorry, Tony....My car will never look as good as yours, at least unless I get some non-stock wheels. Call me when you get back into Lubbock.

That is why I trailered my car 1000 miles from S. Ga. to HPP....

and am anxious to pick it up finished and trailer it back another 1000 miles next week!

You're not alone. They're one of those vendors that you can always trust your car to. Awesome numbers!! :beer:

While on the dyno, among other problems, they noticed the car was going lean, and the voltage was also dropping. The alternator had to be replaced, and along with putting an overdrive pulley on, it should be good now. I am using a 2.8 pulley and a 4lb lower, and I thought I didn't need a larger pulley for the alternator, but it turns out I did. I would recommend that for anyone using a smaller pulley. Lesson learned. In short, the guys at HPP did an awesome job, the coolest guys I have met in a while. On spray it made 631 HP/ 691 torque (on different runs, the torque went as high as 750).

I will post the graph later, but I just wanted to let everyone know that the HPP guys know their stuff for the 03/04 cobras.

(I know they have a 214 area code # as well but it's at work. Hopefully this # is still good for them)
I talked to Manny yesterday about some upgrades in two weeks and can hardly wait. Santa may come early for the humble little DSG 'vert.

Yeah HPP rocks, manny and the boys hooked me up. I made 621 and 680 I believe and backed it up with a 10.64 at 132 mph spinning. These guys rock.

 

[davidsk5018]

Yeah, are you the guy with the vert that they were talking about? They said they thought I could beat that because you have a convertible.....we will see. You ran that on ET streets? Thats what they said.

 

[SWEET03COBRA]
