    1/4 mile time

    For some reason I believe I should be getting better than 13.65 to 13.88 range. And I'm only topping out at 99 to 103. Is this typical? Mods below

    Did you spin a lot coming off the line? What kind of tires were you running?

    Your 60' time is where you need to improve, but overall nice run. A lot of F-body's on stock set-up are able to get their 60' time down around 2.0. Some even in the 1.9Xs range.

    I understand the GTO is set-up differently though so that may be a contributing factor.

    With that said, for every 0.1 second you reduce off your 60' time, you will reduce your 1/4 mile time by 0.2. So, the ratio is 2:1.

    Example: If you were to run again and get a 2.0 (reduced by 0.218) 60' time, your 1/4 mile time would be roughly 13.28 (reduced by 0.436).

    Yes, but how do I improve on that time? I'm guessing this has a lot to do with traction, which i am not getting much of right now. Do you think drag bAgs would make much of a difference?

    Practice mainly. Leave at different RPM's. Use different tire pressures. Try burn out. No burn out.

    You have to get a feel for the car as it leaves. This is much easier with an automatic trans. What stall are you running. You should have 3400 to 3600 rpm stall. If you can hook and get it into the 1.9's I can see 12's in your near future.

    Remove your front swaybar that will give you more weight transfer to the rear wheels.

    Get some adjustable shocks to help with weight transfer.

    Run with 1/4 to 1/2 tank of premium.

    Get everything thats not nailed down out of the car,spare,jack ect.

    Get some Mickey Thompson Drag Radials they are the best hooking street tire.

    Once you learn to harness the power you have and start getting 2.0 and 1.9 60fts or better get a 3600 stall converter and cooler for your trans.

    You won't believe its the same car

    Forgot to mention this earlier. That will destroy your rear end relatively fast.

    GTO's are notoriously tough to launch. It takes practice. Get that 60 down and your times will fall into line. My 04 went 13.69 on Kuhmo's with just a tune. My brother ran 13.40 in his 06 bone stock on street tires. Granted...those were both automatics so much easier to launch than your M6.

    Remove sway bar? I don't know... Anyone else try this? Anyway, flooring it as soon as the tree lights isn't a good idea until I can harness it. Ideas?

    stall it up using the brake and then roll into the throttle...just try different things to get your best 60'

    Most people don't remove the sway bar. They just unbolt the one end so it becomes ineffective. As mentioned, this helps with weight transfer (allowing the rear to squat more during your launch). I don't recommend driving the car around without it though.
