OK, my car can be seen here - http://www.corral.net/forums/showthread.php?t=925968

With the standard HP Turbo kit and a Precision PT76GTS turbo, it put down right at 730rwhp. Well, I wanted to upgrade the turbo, but realized that this would require me doing some additional work to the downpipe and cold side pipes. In fact, I tried to do it last year with a PT88, but found the length of that turbo to be prohibitive. Then I came across this Borg Warner ST80. I have read nothing but great things about this turbo. In fact, there is a guy on LS1Tech that made over 120rwhp more when he switched from a pt76gts to this ST80 unit - at the same boost level of 20#'s. I'm hoping for those same results... We will see. The car is supposed to be dynoed today. I'll let you know how it goes.

Here are some pictures...



I had to do some additional trimming in the fender area to make this turbo fit... Also, I had to have a larger downpipe made because the outlet on the hotside of the ST80 is 4inches.... We just remade the top part of the downpipe and slipped it over the existing part, which is 3.5inches down by the header. Additionally, the new part is made out of 304 stainless steel.



You will notice also that I added a 50mm Tial blow-off valve as well.



Here you can see the aluminum pipes. We reversed the direction that the pipes go into the intercooler. Now the pipe going from the turbo goes into the TOP of the intercooler and the pipe sending the air to the throttlebody now exits at the bottom of the intercooler. This makes for a cleaner look in my opinion. Also, we put a v-band clamp connecting the pipe going to the throttlebody and the pipe coming out of the intercooler. I had some problems with this area before because the hose coupler would blow off under big boost, and it was really hard to get at it in the fender. Well, problem solved with the v-band.



Big thanks goes out to my friends at C.A.R.S. High Performance in Waterford, MI for doing the great work. Sean is the man. check out their website - www.carshighperformance.com

OK, the car is on the dyno as I'm typing. Here's where we are so far...

1. The car just made a tad over 700rwhp @ 16lbs of boost. Keep in mind, it made 730rwhp @ 21lbs of boost with the pt76gts. So, it looks like this thing is going to make quite a bit more steam.

2. The car is breaking up above 6000rpms right now. We are trying to determine why...We think that it may possibly be the TFI module on the distributor. We have a call in to AEM right now (since its still early afternoon in California where they are) to see if we can by-pass the TFI altogether and just run a signal directly to the MSD box. Sean thinks that the AEM box is capable of doing this. We will see.

3. My converter is still waaaaayyyyyy to loose. Doing the math, it appears that it is slipping about 22% right now, which is just ridiculous. It irks me because I just had this thing restalled, too.

I'll report back when we know more.

Well just got back from Milan Dragway today and came back with a new personal best. Car ran really good all day. I definately need an anti-rollbar now. But non-the-less, I'm pretty happy with my AOD-equipped street car that I can lazily loaf down the expressway to Woodward tonight.

I want to personally thank Sean for coming to the track and helping me out today. Definately didn't have to do that, but I appreciate the way Sean takes a personal interest in his customers. Every time we get the car out it seems to go a little faster thanks to Sean's tuning. More of you need to take advantage of this guy's knowledge and ability!

ps. still lovin' the converter Mike (of Ridings Automatics) and thanks for calling me to see what it ran. I appreciate the personal interest you've shown in helping me get the car to go this fast. Still chasing an 8.99 before the snow falls!
