    Original Road Test from Turbo and Hi-Tech Magazine link

    Thanks, I thought everyone would get a kick out of that article. I had to dig through the archives to find it ;-) I did like the references to GN and GNX vs. TTA power differences when dead stock (and new!), I know there are threads at length discussing that topic. :D I am planning on taking...

    Original Road Test from Turbo and Hi-Tech Magazine link

    Hey all, In the process of putting information about my TTA online to assist with its sale I've posted all of the pages from Turbo and Hi-Tech Performance with the original road test and dyno session. I haven't seen this posted anywhere else, so I thought it may be of interest to everyone...

    Spark Blowout on Alky - What Gap are you running?

    OK after slacking for some time I finally put the PAC in the car. I've never run higher than 17PSI or so before, and while tuning the system this weekend I'm hitting a bit of a wall around 20PSI. Car falls flat on its face, feels like typical lack of spark (O2's are ok, no knock, plugs look...

    SMC vs. PAC / My personal experience

    You want to know some pain? Install the PAC when your car already has a preluber installed ;-) The original owner installed one, and it's right in the same space you're supposed to mount the alcohol pump. But it can be done :cool: The fit is pretty tight, but I finally got it all wired...

    porsche 928 s4 thoughts

    I would kill to have my 88 S4 back - grr. Go visit www.devek.net - that's the place to call for upgrades. Their white car is a 210mph land missle. BTW the cars sound bad as hell with headers and exhaust.

    Is the THDP for the TTA supposed to have a O2 bung?

    Yeah I went out this morning and slapped my forehead. Every other car I've had put the O2 on the downpipe, and when I unpacked the THDP it just struck me as odd. It will be my first real mod to the car (other mods on it, but all by previous owner...)

    Is the THDP for the TTA supposed to have a O2 bung?

    I recently got one from John's Performance, and there's no bung, and I'm wondering if this is normal, an oversight (it was drop shipped from TH directly), or an extra I should have asked for. ?

    History Channel Airing Trans Am Show

    I guess they made a show in '95 with the complete history of the trans am. I was flipping channels this morning and came across the end of the show, and they have a section about the TTA and some footage from Indy. They speak very kindly about the car ;-) You can order the car from the history...

    ZF-6 in a TTA?

    Man, I'd love to do that to my TTA. I wonder how hard that really is... (road race instructor, but not with the TTA ;-))

    Exhaust question for you guys...

    Can someone post a part number to this exhaust system? I need to buy a cat-back to mate up with a THDP and that one sounds like the ticket to me. (don't ask, previous owner welded the whole exhaust together, PITA hack job) "My SLP 3" cat back "single dual" system works well, and sounds pretty...

    Tranny HP losses -- FWIW

    It's not a straight power loss, i.e. "just 10HP" if you want to get technical. Frictional losses through the drivetrain increase under load, yaddah yaddah yaddah. But that's getting picky. Most nascar techs I've dealt with throw around percentages, and they lose about 8% through their...
