    INSTALLED and initial driving impressions.


    Compared to my McLeod Twin RXT.
    1. Engagement point is higher (release pedal and pull foot back further before car moves)
    2. Engagement window is smaller (from start of car moving to full engagement)
    3. Reduced chatter.
    4. Reduced driveline vibration and "clunking".
    5. Pedal is stiffer. I attribute this to change to Tick stainless steel clutch line, which was done at same time.
    6. My wife, after test driving, says the car is smoother, not as jerky.
    7. The car is overall more enjoyable to drive.

    Nice.
    Did you happen to weigh it?
    And see if the advertised weight is true.

    I regret getting the 28lb flywheel.
    But monster said they wouldn't sell the 15lb one for a street car. The clutch is so small the inertia is very low compared to a large diameter pressure plate.

    That looks top quality for sure.

    I have the 28 lb flywheel, and it runs great imo.

    I wish I had weighed it, but I did not.

    You'll be hearing from me more in the next couple weeks now that I have my car back. Some guy in AZ stole my all-motor 6-speed record I need to get it back.

    As promised, I'm reporting back with my experience with the RPS/Street Slayer BC2.

    I did achieve my personal goal of an 11 second quarter mile http://youtu.be/0GUgFJ0TXwk.
    Timeslip here:
    Also ran a good 1/8 mile time as well.

    And, finally, this is how I drive it at the drag strip (this was an 1/8 mile pass, thus no 4th gear: http://youtu.be/ZWWIR-JjbF4

    The clutch is no longer a weak link in my setup. I know this because my last pass at Gateway I broke an Axle (a 750hp GForce1320 axle at that). Everything else: clutch, trans, driveshaft, diff, all intact.

    Furthermore, I have had zero missed shifts, shifting at around 6800 RPM's. My light goes on at 6400, and I get the clutch pedal in by around 6800 in 1st gear. I attribute this to the clutch disengaging properly and reliably at high engine speed, even when hot, whereas my McLeod RXT twin did not.
