Ok, I installed the DHP and didn't have a problem (i'm going to go get a case learn in the morning).

I also intalled the Thraser modular system, but now i havea really high pitched whine that sounds almost like it's coming from the alternator. It changes pitch with throttle pressure, even if no boost is shown. So my question is, what would this more than likely be? Alternator, or new pulley?

could be a tensioner pulley going bad, take the belt off and turn all pullies by hand and see if any are going bad

KX2000GTP · #18 10-18-2005, 09:47 PM

how would i know if they were going bad? i'm assuming they wouldn't turn smoothly?

Ripn12s · #19 10-18-2005, 10:15 PM

yup, when a bearing is going bad it will catch or grind

KX2000GTP · #20 10-18-2005, 10:30 PM

I will do that in the morning, Thanks!

I have a question i was wandering how hard it would be to install a ls1 throttle body on my 97 gtp and what are the gains I can expect to recieve from this conversion?

Did you install a new Goodyear Gatorback belt when you did the pulley change? You are in the same area as I am located, we have a 5000 sq ft shop nearby with scanners, welders, lift and some Series II knowledge. BTW, we can run our cars side by side on Hwy-78 to see how they are doing. If you want to drop by, send me a PM.

It depends on what other mods you have or plan on getting. Just the LS1 TB conversion will do nothing spectacular especially without a reprogrammed PCM module.
