Just wondering if anyone has a calculator that can take weight, power and peak torque and give an estimate of 0-100km and 1/4 mile times.

I've kind of decided to aim for enough power to put a Skyline GTS-T (stock) in its place now, which I think is quite do-able.. Here are the figures:

Skyline: 1370kg kerb weight, 186kW @ engine

My car when modified: 1560kg (EA Fairmont Ghia.. I'm pretty sure thats about what it weighs atm), 140rwkW (estimated to be ~220kw at the fly)...

Also, peak torque for the skyline is 294Nm at 4800rpm, while my car has 338 from something like 2500 onwards (from memory).

I know gearing is an issue, but I am pretty sure the 4spd auto combined with the 3.23 diff should give me a competitive takeoff..

So, if anyone knows of a calculator to determine those values, it would be much appreciated :)

Sorry mate... you will need to do better with your gearing if you want a quick take off... thats a start.

yep go 3.9's if ur auto ur take off will be comparable to some manual falcs running round then.

cheers.joe.

140rwkw is more like 200kw at the crank.
As the others have said, you'll also ned to change your gearing, I prefer 3.5's or thereabouts, with 3.7 being the lowest I'd go.

Ohh well.. just found an online calculator of some description, and after putting in various values for power, wheel height (I assume that means from one side of tyre to other, not just the rim) and final RPM, I got the results:
14.7s 1/4 mile (perhaps a little generous, not sure), 88.57MPH final speed, ideal gear ratio: 3.23 and 1/8th time of 9.36 seconds...

That was with: weight 3440lb, power 186rwhp, final RPM 4800 and tyre height 20"..

download cartest
it lets u put heaaaaaaaaaps of details in
weight, power, aspiration, ratios, heaps of stuff :)
ends up fairly accurate if u can work out ya fwkw

is your 140rwkw from a dyno?
140 rwkw = 187 hp which would estimate around 185fwkw, pretty much on par with the skyline, and you have the weight disadvantage.

Although I've driven a stock GTS-T and it aint anything special.

140rwkw is not 185fwkw, it is more like 195-200.
Most 200fwkw AUXR8's produce between 140 and 145rwkw.
The 185fwkw XR8's produce around 130rwkw.
