    OK I'll play this game... What bloody cars?

    Links or reputable references required of course.

    OK I'll say it. It's not humanly possible to pull 6G's (forces needed to stop in 2 meters from 60km/h) without blacking out and suffering internal injuries. You talk so much shit I'm not surprised people talk to you like you're one

    Can't believe this skidmark dude just keeps on going!!

    As i said before, the only thing that's stopping from 60kph that fast is a fucking fist through your gob mate. That is it.

    60^2/254(1G stop right near front lock up) = 14.17m

    -14m flat in perfect conditions and surface is the fastest you are ever gonna stop on your dunlop gpra10's dude.

    -Motogp bike will do it in 10m.

    ya have to be pulling exactly 7G to stop from 60k's in 2m. An F1 car can pull 3.5g from high speeds (300kmh) where aerodynamic forces help it brake. So having said this, you're not seriously fucking persisting you can do it?
    ...Full throttle till you see god, then brake.

    I'm sure. They'd have to, all the riders are 5'4" 45kilo guys that probably need a barstool or a segway to talk face to face... hehehee

    man you have to be taking the piss, the magnitude of your piss taking is very high, what your saying equals to me stating that me on my spada out-drag any nitro crotch rocket, out handle any moto-gp machine, and is more reliable than any 24hr racer.. AAAAAAAAAAHAHAHAHAHAHAHAHA

    Good question, I just had to find it out eh.

    I've been watching quite a few motogp onboard videos quite closely and i came up with some figures from taking speed and time measurements to calculate forces and shit...

    Basically, I look at the REALLY long straights and big braking points that are quite level such as Sepang start/finish straight into turn 1 and Shanghai's back straight which is a fucking monster. I also looked at Catalunya's main straight although i think that is on a bit of a downhill and some other tracks.

    What i found was hard out braking between 13.5 and 13.9 meters a sec decceleration which turns out to be from something like 1.39g to 1.43g (got the exact figures down somewhere)

    Using the same methods i calculated some other stuff:

    F1 cars at around 3.5g.

    Japanese JGTC race cars (calsonic skyline, castrol supra, mugen NSX etc) at nearly 2g

    Look what I found

    Resistance to "negative" (In this case, braking) or upward gees, which drive blood to the head, is much less. This limit is typically in the -2 to -3 g (-20 m/sē to -30 m/sē) range. The vision goes red and is also referred to as a red out. This is probably due to capillaries in the eyes swelling or bursting under the increased blood pressure
    Translation: Your eyes will pop. Soon. Maybe.

    P.S. Theres gotta be a video of some sort of a military G Force deceleration test that can prove how -2g looks like...


    If you can make it on Kiwibiker you can make it anywhere.

    Its ok, before he told me he could stop from 240kmh in 80m on a ZX10R. When i started going through the maths he then changed it to 180kmh in 80m which is still a hard ask. Seems he's been smoking the buds again.

    where opinion holds more weight than fact.

    It's better to not pass and know that you could have than to pass and find out that you can't. Wait for the straight.
