I'm finally getting close to the 10 second mark with my '00 GTS. The track was prepped pretty well, but elevation is about 2700'. The Density Altitude was above 5000' due to heat and pressure. I was on BFG Drag radials, launching at about 3500 rpm. I was using a 91 Octane tune - no 93 octane in Boise My results were: 60' - 1.584 1/8 - 7.159 MPH - 99.65 1/4 - 11.101 MPH - 126.05 Mods are GG Heads and Comp Cam, 1.7 RR, Belanger Headers, HF Cats, SCT Tune, 3.55 gears, etc. I'm a little disappointed in the trap speed. I am hoping for a 10.xx at 130. Maybe when the DA improves in Sept or Oct.
