Kinetic energy and wind resistance ... A- Posted by Kevin K [Email] (#374) [Profile/Gallery] (more from Kevin K) on Thu, 5 Apr 2001 21:32:49 In Reply to: Kinetic energy and wind resistance, TS, Thu, 5 Apr 2001 18:34:13 Members do not see ads below this line. - Help Keep This Site Online - Signup |
slight correction, the 'push' due to drag is related to V^2, so at 90, you have to push 4X as much as at 45. The hp req'd to maintain speed is bases on 'push' times velocity, so it takes 9 times as much hp to stay at 90, vs 45.
For Jason, note that it is hard to load the turbo in 1st to get max engine torque. And 2nd gear ratio is lower than upper gears, and with turbo loaded, the tractive force that pulls the car will be highest in 2nd, for generally highest perceived or measured acceleration. Plus less drag in 2nd as TS noted.
