Message	: Does it mean you can't go faster than that !?? : Matt assuming that you have a twin turbo (3.69 final drive) 5 speed: 1st 3.21 2nd 1.93 3rd 1.30 4th 1.00 5th 0.75 Rear tire size 245/45/16 The formula is: [Engine RPM X Tire Circumference (in feet)] DIVIDED BY [ Gear Ratio X Final Drive X 88] So if you're figuring top speed... Tire Circumference of a 245/45/16 is 6.47 Feet Top Gear is 0.75 Final Drive is 3.69 Assuming you have a 7000 RPM limit.. [ 7000 X 6.47] DIV [ 0.75 X 3.69 X 88 ] = 185.965 MPH -> gearing limited Later, Phuong Pics of ECZA D.C. Meet, 9/30/00 are up ICQ - 59084049 GR Racing When in doubt, mumble. When asked to clarify, say "Trust me".
