i think your right, as with many things the application of the motor is going to determine what we want to acheive with its performance, and like you said huge torque is great for drag and also towing, one thing that may confuse you though is that rallycars have torque figures around 400-500Nm and although this seems to disagree with the formulas a Hp figure of 250 or so, though im not sure what revs it figure is at and this probably holds the answer

might have to reasrch that one!

Thanks, I allways liked phisics and I was learning how to work with java so I added a bit of datto and that came out, it's online since 1997 but it was hided deep in my first home page.

Hope you all like it
Many dream test runs were run on that. Now we have the engine but we lack the time.

youve put the info for your car as standard as the initial values, but the temprature is 70 degress celcius, thats damn hot, is it supposed to be in faranheight (or however you spell that word)?

1200rallycar

The actual operating temp for an A series is 82 degrees celsius or 179 degrees fahrenheit. Remember, 100 degrees celsius is boiling, so 82 degrees is just hot.

1200rallycar 70 degrees Celcius isn't that hot for an engine!
You will find most car with automatic electric fans they come on around 65 - 85 degrees Celcius!

sorry i see now, i was thinking of ambient temprature (atmosphere) not running temp

Quote:That's a good one. Maybe I'll add it to my signature haha.

Quote:That's about 300-370 lb-ft. Which sounds about right for a production 250hp 5.7 liter engine. If the rallycar has an engine half this size, it's probably un-naturally aspirated ...

It is ambient temperature Damn! 5 years later you found a bug, the bad news is that I lost the source code in a hard disk crash so it would be hard to fix.
