After I had my headers modified so I could remove transmission without removing the headers to have the torque converter made looser (higher rpm for launch) off the foot brake. Went to Gainesville raceway for test & tune ( only
open for drag radials and slicks) NO STREET TIRES! I was able to make 3 runs about every 30-40 min between runs. Temp 94+ deg ,they did drag the track prior to making runs. Before I had the converter made looser I could only launch at 1800-1900 rpm. with the looser converter I started out leaving at 2300 rpm first pass. Each run tires were set at front 40lbs, rear set at 18lbs Run 1 LEAVING @ 2300 RPM R/T .157 - 60FT 1.642 -330 4.848 1/8 7.527 @ 91.00MPH 1/4 11.891 @111.70 Run 2 LEAVING @ 2500 RPM R/T .037 - 60FT 1.606 - 330' 4.788 - 1/8 7.458 @ 91.14 - 1/4 11.849 @ 105.47 Run 3 Leaving @ 2700 rpm R/T .080 - 60FT 1.628 - 330' 4.814 1/8 7.489@ 90.58 1/4 11.858 @ 112.01 ( TRACK GOING AWAY SPUN) Run 4 Leaving @ 2700 spun real bad abort run I even tried dropping rear tires to 17lbs No sense beaten car up if I'm losing traction. So I set the tires for the drive home. Well i found that I can leave at a higher rpm off the foot brake, just need more seat time in the car. Next test and tune (NO STREET TIRES) AUG 14th ORLANDO SPEED WORLD |
