Race Car Acceleration Rates??? Hi There, I have been on the web for two weeks now trying to find an answer to my situation. There are no calculators that I can input the numbers below in to find out what is best. The rule in road racing is he who can accelerate the hardest out of the corner and down the strait will win the race. First my question then I will supply some information. Which will accelerate my race car faster? Being at a lower RPM with a higher torque rating but less HP or being at a higher RPM less torque rating but more HP. INFORMATION: Car: Mazda 1.3 Liter Rotary RX-7 5 Speed Weight with driver: 2425 lbs Tire Diameter: Choice number one 24.5” Choice number two 25.7 Final gear ratios: 1st 17.868 2nd 10.337 3rd 7.136 4th 5.13 5th 3.909 Rear end ratio: 5.13 (Note 4th gear in transmission is direct drive 1 to 1) Power Range: @ 5000 RPM 79.6 HP 85 Ft lbs Torque to 7750 RPM 163.8 HP 111 Ft lbs Torque to 9000 RPM 174.1 and 101.6 lbs Torque. Note Torque on this engine @ 5750 RPM is 100 ft lbs and peeks @7750 RPM 111 ft lbs and drops back to 100 ft lbs at 9100 RPM. So for 3350 RPM the average torque is rated at 105 ft lbs (A very flat torque curve in this area) . Engine Dyno Ratings based on 4th gear test: Test #1 Road speed 120 MPH 8424RPM 168.4HP 105 ft lbs of Torque. Load at rear tires.226g. Tire diameter 24.5” Test #2 Road speed 120 MPH 8027 RPM 165HP 108 ft lbs of Torque. Load at rear tires .244g. Tire diameter 25.7” From every thing that I could figure out I believe I have enough information to solve my problem but do not know how. Please help and send the proper formula that relates to this problem. In this way I can work things out at a later date after making changes to my car. Waiting for a positive reply thanks guys.
