Good 60ft + shit MPH = good ET??? WHY?

Why does it everytime i land a good 60ft my MPH suffers...

The shitter my 60ft the better my MPH...

Does it sound weird.. or am i driving strangly..

I have notice this on other peoples runs too.:thumbsup:

when i ran a shitter 60ft, my mph was higher, because i had higher psi in tyres. the higher psi makes it harder to launch (shit 60ft), then once you're on the roll, for hte next 380metres, your car will have less drag coz you got higher psi in tyres. hence ! the better mph

my theory is.. if you can master a sick ass launch on high psi, your ET will be hektikk with a sick ass mph.

hmzsz... i was running 20psi and got 2.3 60ft @ 159kmph
18 psi and got 2.2 60ft @ 151kmph

the lower 60ft time worked out alot better

every 0.1 off your 60ft equates to about 0.2 off your et

that's only true if u maintain ur mph, and if u drop psi, ur mph wont be as high.

basically everything zco said summed it up

When you load the motor with a good launch, you lose MPH. It's unavoidable.

untrue..not always the case. i have made 2 diff launches. same mph diff 60ft times.

if you get your 60ft time lower, then obviously, your mph at that instant will be faster, but for the remaining 380metres, your mph will gradually become lower... it all comes back down to psi in tyres

That couldn't be more incorrect. It has absolutely nothing to do with tyre pressures. Its all about traction off the line, leading to better 60' times and then mph at the finish line. Tyre pressures may influence your traction but it is not because of tyre pressures your mph will change.

This is exactly what i am saying, its a weird debate..


Zico.. look at your slips man: http://www.ozhonda.com/forum/showthread.php?t=52395

your 2nd shitty run had a higher mp/h than your best run (ET 14.8)
were u running the same tyre pressure?

so you're saying, if you dont launch, taking off slowly, at 5psi on tyres, you can get a higher mph than on 40psi ? i dont think so.

no. i was runninng diff psi on tyres. that is why my 60ft time was better (coz i lowered it) and getting a lower mph.

you gotta factor in the way you drive for the runs. i drove the same way, and launched the same on the last 2 runs. so if you compare the last 2 runs, then what i sed is correct. if you look at your time slips,(keeping in mind you drove/launched the same way on those runs) you will see that what im saying is true.

that is the only logical explanation
