Re: TurboTPI upgrade....Finally
Mine is the quietest at the track usually. The only problem is it can be impossible to hear what our own cars are doing next to a lot of cars. I do love outrunning those obnoxious open header trailer cars on occasion though! Long live the silent hissers!

Got a cool sticker for under my hood. It should really confuse people at car shows that catch it. haha

Re: TurboTPI upgrade....Finally
Well, the trans started acting up in 3rd and 4th. It would slip in either gear if i get into boost. So i figured the 3/4 clutch is just finally worn out after years of abuse. It was fine during normal driving. None the less, i figured i should quit driving it just incase something lets loose. Didnt drive it for a week, then had to move it out of the garage for my sons 3rd b-day party, took it for a short drive and got on it in 2nd gear and pop. Car acted like its in neutral. Stopped it, nothing in any gear, no trans fluid leaking, and it make a whining noise when reving it in any gear. So hopefully, ill get it apart to see what happened this weekend. Thinking input shaft?

Re: TurboTPI upgrade....Finally
I forgot I had this thread going. Its been awhile. Well, where I left off, the input drum exploded in my 700r4. The car sat in the garage almost 2 years before I did anything to it. Between work, 2 kids, messing with my new daily driver, I finally got another trans put together. Its not built the way I really wanted, but I couldn't afford that at the time. So its pretty much the same setup I had. It lasted along time before, so I figure I'd be ok for awhile. So I get the trans in, go to fire it up, she starts like it ran the day before. I love this car, it just works. Its been together a couple months now and I've been driving it a lot. Trans feels good, all shifts are nice and firm. I'm planning on a trip back to the track in two weeks. I'm excited as I haven't been back to the track since the 76mm turbo has been on. Update to come.

Heading to Union Grove or Joliet? I think I saw you run close to ten years ago at the Grove. Your car is awesome.

Re: TurboTPI upgrade....Finally
I should be there the 18th (Next weekend) with a group of cars. Hopefully the weather cooperates.

Re: TurboTPI upgrade....Finally
awesome car. and love the videos.
i have referenced your car here: https://www.thirdgen.org/forums/auto...ng-appearance/ btw. i hope you dont mind.
i've been really wanting to do something like this with my car ('89 Formula 350). i read in your (Pontiac HP?) article that you had a forged, low compression block on hand for your turbo build. mine is about a 9.5:1 with hyper-eutectic pistons. is that something that you can throw forced induction on?

Re: TurboTPI upgrade....Finally
You can run forced induction without a problem at 9.5:1. Obviously youll have to be alittle conservative on boost, but it can be done no problem. A matter of fact, my buick regal has higher compression pistons than stock, it is the same 9.5:1 that you have. With an m90 blower without intercooling i'm running about 10lbs of boost without detonation problems.
