    Last month start up.......

    I have a question. I replaced the inner torque limiter inner clutch (2011 Busa) with a billet clutch. It turns out that the billet clutch is designed for a lock up style clutch and the spring retaining arms are short causing the springs to coil bind. I can simply put spacers in there but now it's got me thinking of a lock up style clutch. Have any of you guys used the lock up clutch or is that just a drag racing application? With the added weight of the car and a turbo I'm thinking the clutch needs a little help especially on hard launches on pavement. Thoughts...

    Thanks

    Congrats AK! Badass!

    That's not what I pictured the frame looking like but OK, I can see where your going.

    Watch That master switch! The big red paddle one. They are not made like the old school ones. I had one fail almost immediately in the Briggs. I ended up taking the new and old one apart and making one good one.

    I think I bought mine from Longacre? I had pics on here of the difference inside, I'll see if I can find them.

    EDIT: cant find the pics. If you start having electrical problems, look at that switch.

    Can you swap out the towers from the original setup? They are red loctited in, btw.

    No need for a lockup clutch on a stock or near stock motor, they are meant more for racing where you can adjust their slip, and make them grab at a certain rpm for consistent hits. I assume you are asking about a single stage.

    The busa clutch is pretty robust as is. I didn't bother to take the back torque limiter out since it only acts on engine braking, and the sand really slows the vehicle down, and I'm never in a situation where the engine is being forced to a high rpm.

    Oh, didn't see you were going to turbo it. Heavy springs may be enough in that case.

    Billet basket and HD springs. Later yr Busa have a better basket already, but billet is still a good idea w turbo.

    I thought the Gen II Busa's don't turbo as well as the Gen I because of the higher compression?
    Awesome project as usual for Ak.

    Properly built, either one will turbo just fine, but the gen 1 can take a few more pounds of boost with less octane.

    I've heard the gen 1 cases are a little beefier in some sections, and some of the guys pushing the limits go back to gen 1 cases with the gen 2 crank and head. Maybe it was just the cylinders....

    The gen 2 ecu is far more capable though. Addition of boost is easily accommodated without a fuel pressure regulator.

    I've seen 6lbs for a gen 1 and 4 lbs for a gen 2 before you need to open it up for mods. I would be careful with boost on a stock motor though, these heavy vehicles definitely tax the motor harder and longer than a bike.
