    i see that Chris went .934. How are they doing this? Assuming a low gear of around 1.60. What clutch, timing, lean-outs, wheelie bar height would they be running.

    What you are asking for is a good chunk of his tune up.

    There are competitive cars running anywhere from 1.56 to 1.76 low gears.

    Some cars run a base heavy with a little counterweight and some run a base light deal with a bunch of counter.

    Some cars pull a lot of timing out, some cars pull a little.

    I've heard of tire pressures from 4.5 to 6. Wheelie bar will be from 1.5 to 2.5 to the bottom of the wheel.

    Marshall has a MBR engine combo, and an S&W chassis (single diagonal in clutch bay) so what works for his car won't work for another. With all of the different head combinations, different camshafts out there, etc., there's a wide array of torque curves from one car to the other.

    So even if Chris got on here and said he took 5 degrees out at .xx to 1.xx and opened a 50 jet at .xx to Z.yy, that's all very relative to his combo and car.

    The idea with pulling power out is to get enough power out of it to fix the shake zone without making changes to it that will effect the whole run.

    You have torque at the flywheel & load at the track. In order to accelerate at TAFC performance levels, something has to give. Give happens at the tire & the clutch. Of course the torque & load are variable by conditions & tuning (not to mention lucky tires). It is a simple equation:

    Mike; trouble is only a few sit down and think anymore. Monkey see/Monkey do ! Every car out there is different, figure out what YOUR car is doing and fix it! It's easier than sorting out bad info!
    One small case in point : NO racer would run his valve springs at near coil bind, but over 50% run their clutch springs right at bind with three times the heat.....and never even thought about it.

    Not seeing why these numbers are such big deal. We had .94 and .95's constantly way back in early 90's. As much power as motor could make and control it with clutch.

    As stated by Will earlier. We ran low static and heavy weight. Back then the blowers where nowhere near as good and the tires where lacking some too.

    .93 60 foot is not that big deal it's what you can ran at the 330 and 660 what matters.You can do it many way's and with out a lean out system active.We ran 5.50 on the main yet
