    I agree, that's a awesome tranny... can't say the same for the SMG transmissions though. My buddy Russel went through 3 of them in 60k miles... he sold the car. lol

I put down about 350 lb-ft of tq to the wheels, and at the drag strip I launch at 7k and I've done over 400 passes (have the bag of time slips to prove it, lol). Stock tranny, stock axles, sometimes a VLSD, others a KAAZ 1.5 way. And I have NEVER broken anything. I will stick with the stock SR trans until it does break. Hoping to have over 400 lb-ft of tq with my new setup, so we'll see!

    That was not arguing the m3 tranny thing you posted or anything, just popped into my head. Ha ha. Does suck that it has to weigh that much though!

    Keep in mind that 55 lb tranny survives just fine behind a 3.2 L I6 even when turbo'd. 500-600 ft lbs of tq at the wheels isn't that uncommon for them.

    Here's a little burnout video I did for fun (getting rid of some old tires I had, lol). Too bad it was a windy day...

    Second gear btw: http://www.youtube.com/watch?v=S8oss1RAqOQ

    When I pull the KA out of the Convertible, I'll weight that tranny as well, lol.

    26x8.5x15 Mickey Thompson ET Drag Slicks running 13 psi of tire pressure (warm). 60' are 1.61 to 1.65 on avg. Trying to get in the 1.5s or even 1.4s, but my lighter flywheel and lack of boost off the line is hurting me, lol.

    98lbs? I thought it was closer to 75?

    Huh my ka trans don't feel that heavy. They suppose to be the exact same right? I mean other then bolt patterns and minor stuff like that.

    SR transmission with little to no oil or shifter (mounting plate included), but with throw out bearing and clutch fork; weighs 93.8 lbs consistently. I have a digital scale that calibrates it self every time, and I did it 5 times with the same result every time. The tranny was completely on the scale; it was not touching the ground or myself in any way.
    Sounds about right... that thing is a heavy SOB.


    Kinda sucks that something like an E36 M3 trans which can probably handle just as much power (or more) weighs like 55 lbs it feels like. Seriously lightweight.

    You can do an engine with two bathroom scales (should be below the 250-300 lbs each can go up to).
    I'll have to grab one more then, lol. My scale goes to 350, but two scales will be easier I think.

    Thanks man.
    Ahh totally, I got ya. When I get close to finishing everything (I'll keep this thread updated), just remind me, ha ha.
