    need HVAC diagram

    Does anyone have a diagram of the vacuum lines for the HVAC system for 1987? Also on the HVAC panel, which lever functions should cause the heater valve to open and let coolant into the heater core? Thanks.

    running E85 w/91 oct chip

    I have a chip for running 91 octane and alky, but am curious if I can run E85 on this chip without having to have an E85 specific chip burnt. The motor has 124lb injectors that the previous owner ran E85 with, 8an feed/6an return Racetronix fuel lines, and a 525lph Hellcat fuel pump. Thanks.

    Pure Stock Drags late 80s/early 90s

    This really puts into perspective just how much of a beating the turbo Buicks put on the modern muscle of the time. Wish I were old enough to have seen this in person, but this video is the next best thing. Seems Lawrence Conley had a really fast GN in the low 13s.

    how would you fix this-hood latch support

    The metal looks too thin to weld, so I'm thinking about using some sort of panel bond or adhesive. Not sure how that'd hold up though, so I'm looking for suggestions on how to fix this.

    coolant spray on drivers side head

    I'm trying to find the source of this coolant spray on the drivers side head. Before you ask, yes it is coolant...or what's left of it. The cooling system was left in pretty terrible shape by the previous owner. Any ideas where this could come from? The headgasket looks fine and the nearest...

    Husek built transmission, core trans/w converters, and drag wheels/tires/Mickeys

    Up for sale is a sub 500 mile LU trans built by David Husek and is rated for a 9.80 ET. Not sure what went wrong as I haven't opened it up, but the front seal is leaking badly and the forward gears feel like they're binding up. Reverse worked fine. This happened after a pass at the drag strip...

    head studs won't loosen

    I'm going to be replacing both headgaskets and in trying to loosen the studs, am afraid to break the allen wrench on the stud. Short of removing the engine to replace the head gaskets, is there an easier way? How about removing the heater box and brake booster(vac brakes)? Any tips to try to...

    new tax law coming Jan 1

    Has anyone heard about the new tax law of reporting profits of $600 or more on private transactions? Maybe I'm reading this wrong, but this sounds like some serious over reach. So...if I sell a car for over $600, then I have to report that gain on my taxes, correct? If so, that is utterly...

    intake manifold gasket problems

    I replaced the intake manifold gasket a couple months ago and have slowly discovered the oil is slightly becoming contaminated with water(no antifreeze). No oil in the radiator. I initially thought the oil might be milking due to too much methanol being sprayed, but ruled that out after turning...

    If this is a real GNX...sigh!

    Just appeared on YouTube. Looks like 021...anyone know the history on it? Also looks like the rear wheels don't have the deep offset like factory GNX wheels. Clone or the real thing? If real...jeez this reminds me of #239(or maybe it was #237) that was on Columbus, GA Craigslist several years ago.

    200psi transducer

    I'm going to be logging alky pressure and am looking at 200psi transducers, but see a wide range of prices. $20 up to a $150 Holley unit and beyond. Anyone have experience with the cheaper ones? Also, how do they hold up when exposed to methanol?

    PL file critique please-suspect false knock

    I've gotten everything pretty much wrapped up with the new combo, and here is a log of where things stand as of now. Something is setting off the knock sensor in the low gears, but 3rd(no downshift) looks pretty clean. Fuel pressure(100psi sensor logged in the place of "volt 4") looks great and...

    Tuning based on alky pressure

    I'm thinking about starting to log alky pump pressure. Besides knowing what psi the pump is putting out, is there any way to use this info for tuning?

    Fuel Pressure gauge & Powerlogger reading

    I've just wired up the Powerlogger to log fuel pressure and there is a difference between the two readings. The fuel pressure gauge is an Autometer with electric sending unit. Not sure if I'm going about this right, but in the .INI file for the Powerlogger, I've modified the...

    PAC alky control install issue

    Just wanted to bring this thread back for anyone considering using an older controller. It's not worth using an old controller when so much is at stake(your motor). Not to mention, the older kit had 3 components that all had to work together(PAC, small box with relay built in, and a square deal...

    cylinder 1 spark plug oddity

    After putting some miles on a set of new Autolite 23s gapped at .025, it looks like there's a problem with cylinder #1. Take a look at the pic. I'm running dual nozzle alky, so is that why the other plugs are so clean? Also, running an RJC power plate. Does it look like the alky isn't making its...

    need TR6 info-no start

    This TR6 came with an engine/trans combo I picked up a while back, so the switch settings were set according to the way he had everything set up. I'm only looking to use the 2 step by applying 12v and not ground. I've switched modes 1-8 all OFF except for Mode 4 and 8 are ON. All the config...

    Average repaint cost?

    I've been chasing my tail on a WOT issue where the car will just fall on it's face and won't shift into the next gear. It's mainly on the WOT 1-2 shift, but it sometimes does it when WOT downshifting as well. I suspect it may be weak valve springs in some reading here about the issue. As shown...

    coolant temp reading-PL or gauge?

    Between the coolant temp in Powerlogger vs the Autometer gauge, there is about a 15 degree difference. Which do you think is more trustworthy? The Autometer gauge/sending unit is of unknown age, FWIW. It's an electric gauge. edit* The reading in powerlogger is the higher one. Gauge shows about...

    late 1-2 shift at light throttle and none @ WOT

    At mid throttle, all shifts are nice and firm but at light throttle, the 1-2 shift occurs around 2800 which is a neck snapper. The 2-3 and 3-4 shifts are a little late but nothing major. At WOT, it won't go into 2nd gear and will just take a nosedive until I get off the throttle. It has an FTS...
