She made three passes last Sat. I don't have the timeslips in front of me for the full run down but here are the basics off the top of my head.
1st pass:
60' - 2.00
1/8 - 98mph
11.57@119 (16lbs. of boost)
2nd pass:
60' - 1.98
1/8 - 100.6mph
11.39@120 (17lbs)
First pass during eliminations:
60' - 1.86
1/8 - 97mph
1/4 - 11.87@104 (~15lbs. of boost)(lost the carb hat gasket :x, and she was lifting to not break out.) Dial-in was 11.50.
The DA was hovering around 4690 ft.
According to www.speedworldmotorplex.com the HP at the flywheel was 446. There was approx. 378 hp at the tires. We need to get around 500hp at the crank to make the 10's! The car weighs 2805lbs. with Kelly in it.
We've determined that the crappy 60' times are due to the larger port sizes in the Oz head/intake vs. the log head. This same setup but using the log head proved to make more low end torque to get the car moving. Her best 60' time using the log head was 1.67, with an average of around 1.76 or so. I also changed to a early model timing chain installed straight up. The old chain was a later model one that normally would be 8* retarded but I skipped a tooth with it so it was 2* advanced. So that too may play in with the slower 60'.
We could change the converter, raise the lauch RPM etc. to help this out, but for now we'll leave it like it is until we can test the ClassicInlines aluminum head.
Later,
Will
