Well I had the pleasure of driving an SP63 equipped 6 speed at Bradenton Memorial Dragstrip this past sunday. The car had the above mentioned SP63 (first time driving one ) mounted on an HKS header, with an HKS wg and what appeared to be an SP dual feed fuel system, VPC, GCC, Profec b, and Arizona clutch (first time driving one
with a B&M short shifter (first time again)
I arrived with et streets on ccw's to meet the owner, we only used the backs (no skinnies)
Well the first run was used to set the boost level and feel out the clutch, turbo and shifter. The run felt good, but the launch wasn't all there....10.9 @ 129 1.68 60', boost ended up around 1.7 kg and 670c egt's with probe mounted in dp (rich)
The second run turned it up a bit and went out again, the launch was about the same (both runs let the clutch out a bit too early with the revs too low) 10.8 @ 130 1.68 60' , boost was about 1.9 and egt's about the same.
Third run I felt more comfortable with the clutch and luanched it much better....but missed third !shit!. 11.00 @ 131 1.59 60' , Same boost and egt's
Fourth run, nailed the launch and hit the gears pretty well and went 10.7 @ 131 with a 1.55 60'
Fifth run was hotlapped and nailed the launch really well but missed second as the clutch was a bit reluctant to go into gear
would not go in until the third or fourth try. This run was an 11.6 @ 130 1.54 60' (remember 2nd gear is still within the 60')
Anyways, with the car tuned a bit better and getting the 60's that I got at the end the car should have no problem doing 10.40's at around 134-135 and if the temps were better ( they were in the upper 80's easily) the car would go faster still.
I had to cut it short to make an appointment, but I will try to set up another outing. Te owner was very happy as he had only hoped for 11's this first outing.
