Drag Strip performance:
I took the car out to Bremerton Raceways in Bremerton, Washington on a Friday
night after work to get a few runs in on the last day of "Test &
Tune" to see how the new ported heads performed. Much to my
disappointment traction with street tires was terrible, especially between the
100' mark and about 300' out. My 60' time was actually one of my fastest
to date thanks to the 4.10 gears, however, once the RPM got past ~4500 RPM in
1st gear the tires just started roasting. I could not shift the car hard
into 2nd gear without just about losing it entirely as the rear tires violently
broke loose. And to top matters off, when I finally was able to control
the traction a bit better, the new found horsepower caused the clutch to begin
losing its grip and started slipping while shifting from 2nd to 3rd and then 3rd
to 4th gear. The following run represents the best traction/clutch limited
run of the evening:
60' | 2.099 |
330' | 5.590 |
1/8 | 8.372 |
MPH | 90.23 |
1000 | 10.733 |
1/4 | 12.684 |
MPH | 115.88 |
This time only represents a -0.03 ET improvement and +2 MPH gain due to the poor run. Overall I certainly can't complain at the fact that even with these times the car still just flat rips for street tires and closed exhaust. I know that the car has so much more potential that I will have to tweak this combo a bit more. I guess there's always next season with a new clutch a few suspension mods and stickier tires! It's time to put a new clutch in next month :>(
