calculator

http://www.mk5cortinaestate.co.uk/calculator4.php Just a neat little gizmo. I know its not going to be super accurate, but gives you a quick reference point. 140 hp vmax = 113 hp at the wheels..... so its not really far off.

Is there a gearing calculator out there for the Vmax? I've been using: http://www.endtuning.com/gearratios.html Putting in my wheel diameter, width, and aspect ratio. Plugging in the gear ratios, but seem to fall short on the diff ratio. If there isn't a specific gear ratio calculator out...

I like this one because you can view a lot of sizes at the same time. If you don't see what sizes you want, just type them in. If you need more rows to calculate just drag the formula straight down to add as many rows as you want.

Very useful when considering different tire sizes or setting a digital speed that requires inputting tire circumference. http://www.discounttireshopper.com/calculator.htm
