Hi All
just google / search for online speed calculator
but here is a good site with plenty of links
also you can find excell sheets
The best program to use is 1/4jr & dyno these are older dos programs, for windows you can use dyno 2000
they may turn up on a google search or a torrent, but they are commercial ( bought / paid ) programs , i am just pointing you in the right direction not telling you to do something illegal, there may be limited or trial versions available.
For free online simulators / calculators i use this site with a fair few web pages listed
Wallace Racing - Automotive Calculators
you may also need a metric to imperial calculator, use a online one, but there are some good utilities you can download
But the results are not perfect, instructions are vague, so some may be for rear wheel HP, but dont actually say , others ( usually USA ) like to use engine flywheel HP as a example
So some stats for a VT SS
We know the weight is 1643kg ( hmm my rego papers say my VT SS 304 is 1504 )
so 1643kg = 3662 pounds
We know it is rated 179kw , this is 243 HP ( roughly we use 1/3 to go HP to KW , also as a coincidence we also use 1/3 to go from engine KW to rear wheel HP as driveline loss is about 1/3 , so sort of funny a 180kw engine , should show 180 hp rear wheel dyno as a guide )
the maths in some 1/4 programs came back as follows - best time 14.33 , which is think is a bit high , i dont have any proper trustworthy articles here but i would be suprised that the Gen3 would be a 14.3 car , the 304 to me would be a 15.5 -16.0 car
Power to Weight Ratio: 14.91
60 Foot E.T. : 1.99
1/8 Mile E.T. : 9.04
1/8 Mile Trap Speed : 75.15
1/4 Mile E.T. : 14.33
1/4 Mile Trap Speed : 93
1/4 Mile Trap RPM : 3,985
