RE: More RPM from my 390 |

The only reason for your car to go slower with slicks and a tighter gear is; 1. too much air in the slicks and you had too much slippage or; 2. too little air in the slicks and you had more traction than your engine could provide power for. These are critical areas much like engine tuning and it takes several runs to get close to the potential that your car has when running slicks. When I raced a '57 Fairlne 500 with a low riser 427 I ran 4.83 or 5.14 gears with 9" Goodyear slicks, 26.5" diameter and was turning 11.9 elapsed times at 118 mph. My slicks got stolen and before I could recover them I cut my fenders and used a friends 14' X 32" funny car slicks and the tire growth slowed me into the mid to high 13s. The tire growth changed my gear ratio dramatically, I only made about 3 runs and gave up in disgust. Ruined a beautiful car too. |
