    Power Master 30 amp fuse keeps blowing

    Try putting an ad in the “Parts wanted” section for the powermaster motor. You might find someone who has it. Richard Clark may also rebuild them as well. However, replacing the whole Powermaster with a vacuum brake setup is by far the least expensive route to take.

    Carnage from GS Nationals !!

    Do you think a Girdle on the block would have helped prevent it cracking like that ?

    Meziere H2O pump

    There are many members here including myself run the Chrysler Intrepid dual fans from early 90’s. They require simple mods to mount them and electrical harness adapter and relay. Do a search and you’ll find plenty of info.

    Meziere H2O pump

    Before you try a new water pump, replace the stock fan with a dual fan setup. That should help a lot especially with front mount inter coolers.

    Fuel sender connector burnt ?

    Sure, those contacts are tiny. I’m guessing that they would not handle 5 or so amps per circuit. So, you’re probably exceeding that especially at 60 psi. Amperage draw is higher. That would explain the melt down as well.

    Fuel sender connector burnt ?

    That connector melted due to high resistance through the male pin/female contact. Corrosion on the plating of the contacts or “loose” female contacts which affects the spring force on the pin. Those are common failure modes. Additionally, when using 2 pins to apply power (splitting) sounds like...

    Here’s a pic of a replacement for a 84/85

    84/85 injector wire harness vs 86/87?

    They are not interchangeable as they have different connector setups. The 84/85 used 2 connectors while the 86/87 uses a single connector.

    Motortrend GM Muscle Car History

    Very well written article with a lot of information on these cars. The one thing I’m wondering is on the development of the GNX. Did they actually modify or replace the cylinder heads ? I was always under the impression that they did not.

    GN's built in Pontiac MI per day?

    Great info, Thank you. Interesting they upped the Turbo Engines to 125 builds a day. They were also setting up stock for Pontiac ASM for Grand National extensions. Which would be the 1500 Pontiac Turbo Trans Ams in 1989.

    GN's built in Pontiac MI per day?

    If you pull the rear seat out there should be a build sheet in there. Mine was dated 10/27 which is the date of Fischer body build. Final production was done on the following day. That’s my understanding at least.

    GREMLIN CONTINUES TO BE PRESENT MAKING DRIVING UNSAFE

    Use your scan tool and post the numbers at warm idle. MAF, BLM, INT, BAT, etc. A Powelogger file would be very helpful otherwise it’s a guessing game.

    how's your wheel size

    The tire selection for 16x8 rims is almost non existent. There are no 255x50x16 street tires available in my searches. Just some drag radials or 275 versions.

    GN1 72mm T/body

    It’s great looking piece, but it’s very pricey. If you have stock plenum adding an RJC power plate will improve the air distribution for considerably less. GN1 claims there plenum improves air distribution, but I haven’t seen any data published verifying that. The gain here is you don’t lean out...
