    Cadillac DeVille 1985 to 2005 including:1985-1992
    Gentleman, my humble apologies for the delay in getting my vehicles tested and on the dyno. In the world of making electricity spare time is not an option. On to other things of interest.

  5. Thoughts on the original SRX in preparation for testing the 2010

    Cadillac SRX First Generation Forum 2004-2009
    I'm headed to the Cadillac of Crossovers drive event this weekend to see how the 2010 SRX matches up against the BMW X5, MB GLK, and Lexus RX. It spurred me to write a bit about why I like the original SRX so much. It's a quandry - I like the 04-09 because of qualities that the 2010 doesn't...
  6. Gforce axle testing conclusions

    2004-2007 Cadillac CTS-V Performance Mods
    After some testing and brainstorming with dannboss and Whisler151 (2 great guys to deal with BTW) it's been determined that the 04-05 CTS-V's needs the big passenger side axle to stop the wheel hop. The 06-07 CTS-V's need a small drivers side axle to stop the wheel hop. The trick is to vary...

    I have four Northstar engines sitting on the floor in the garage. These engines have come out of parts cars, and have not been started. What's the best way to determine whether the HG's are any good. I've filled the engine with coolant (as best I could without a radiator), and charged each...

  18. Testing a Fan Control Module?

    Electrical Technical Information
    '87 DeVille. I'm pretty-sure I have a bad module. I tested the fan-outputs for voltage and each shows less than 6v. Neither fan runs, both are good, and power to the module is present. I'm trying to find a good used-module, #1641400, since I can not afford new. Is this voltage test correct...
  19. Perfect way to add Aux in to '04 SRX - here's how

    Cadillac SRX First Generation Forum 2004-2009
    I've been lurking here for about a week since we purchased our '04 early build SRX with Nav/Bose/No XM. This one has the analog squiggly antenna and no XM module, so from everything I read here adding fun stuff like the ipod and xm or sirius is next to impossible without taking it to GM for the...
