tonight I ran my 97gt for the second time. Last week I ran 14.8xs at 95mph at San Antonio Raceway, Stock.
Tonight, I went to the track again. The car is a 1997gt, with 150,XXX miles on it. It has 2.73 gears in it. Since last week, I installed a set of steeda pullies, an h pipe, and drag radials.
I headed out to Houston Motorsports Park, an 1/8 track tonight..
run 1
2.17
6.18
9.46(1/8)
74.70mph
run 2
2.30
6.21
9.44(1/8)
75.85mph
both runs the tire pressure was set at 11.5-12psi. I launched the car at 4800rpm's, and both times, the car just bogged. It fell flat on its face. BFG's hook way, way more than nittos that Im used to running on.
run 3
2.06
6.01
9.24(1/8)
75.67mph
run 4
2.02
6.56
9.19(1/8)
75.77
both runs 3 and 4 were with the same tire pressure. I launched the car at 5800rpm! Ive ran drag radials for years, but couldnt imagine launching at redline on 275/40-17 inch drag radials. I guess (est) 200-215rwhp and 2.73's has a bit do with being able to launch that high. However, the car still bogged but the sixty foot did pick up a bit. Suggestions are welcomed.
