I made my second trip to the track since building the motor. Air was really nice for my area today, We saw negative DA which almost never happens during the racing season. I got 6 runs in today, and despite the awesome air I did not hit my 10.9 ET goal. I was very close though..
Here is the build in short
11.85:1 383 pump gas
LE 215cc Trickflow heads
Jones Racing cams solid roller ..
259 - 260 .68x/.67x lift on a 110
The drivetrain is in my signature.
Rear suspension is all tubular, adjustable torque arm, MWC anti roll bar and weld in subframe connectors.
6 passes total today, making small changes to AF and spark advance. Last two passes I bumped timing 1 degree on each pass - picking up MPH on each.
DA -200 ft, 2nd pass
34* advance 12.5:1 AFR
1,55 60 ft
7.05 @ 98.71
11.06 @ 122.88
DA +400 ft last pass
36* advance 12.5:1 AFR
1.56 60 ft
7.06 @ 98.75
11.07 @ 123.05
Other times were 11.08, 11.08, 11.12, and 11.27. Pretty consistent.. The 60 ft stayed at 1.55 consistently, with some variation due to wheel spin.
The stock shocks and springs have to go.. A restall on the converter after a dyno tune, and maybe I can get some high 10 second passes..
