Ok, how accurate is this?

Miles Off. 500hp 2700 lbs (predicted 14.bla) actual 10.50

Dont know,,,but i just ran a 3.57,using only 16000 horsepower and about 750 kgs ,then got bored went back on the porn.........................................bill

For me it wasn't far away.It predicted 7.53 at 1550kg and 2350hp.I ran 7.41 with that HP..

Reasonably accurate for me (with the usual caveats -- the engine hasn't been on a dyno and the car hasn't been on scales, so I'm using estimates for both)

[liner33]

Doesnt allow for traction issues either

[veryoldfart]

it says it refers to recorded runs, maybe not just mathematical formulae

Crap

Cannot beat getting your arze on the start line.
The timing slip will give you your answer.

I use this...

Ive found its quite accurate for my car (TVR Chimaera with nitrous and Mickey Ts)
But i use it more as a comparison tool to see how my nitrous system is performing.
ie enter the numbers to match a non gas run then see the power difference on the gas run. Its help me tweek my nitrous system and get the most out of it.
Its also very useful to work out how much more grunt you need to reach a certain 1/4 time. (ie 10.99 for me) Its quite a lot!

Hmmm, never know with these things, according to this it took us 2800 HP to run the 6.42 as were heavy at 1100kgs and that was a 1000 foot pass.

[MotorPsycho]

without taking into account tyres sizes, gearing and such like you'll never get an accurate picture, for some cars though it does seem to give a rough estimate

ive just found what i need HP-wise for my minibus to run a 5...

Miles out I found, according to that it took 3500+ bhp to wring a 6.23 out of Graham's Superbird lol. Looks like our mission to stuff screw rotors in to a roots case worked ha ha
