Computers are a huge help to drag racers, giving them a complete picture of the performance of all the systems on a race car during a run down the track. However, seat-of-the-pants intuition remains essential.
As the Cuda Beast's lagging 60-foot times pointed to the need for a different torque converter configuration, Paul also suspected from the driver's seat that the engine seemed weak. Last weekend, Paul decided to perform a leakdown test on the motor, and found that cylinders 1 and 8 were leaking, 8 especially. Paul said normal leakdown on his motor is no more than 6-7 percent; cylinder 8 was 35 percent, enough that air could be heard and felt. That indicated a blown head gasket -- detected early enough that the Beast dodged damage to the head and/or block that would have ended the season. Paul had new head gaskets on hand, and at the end of a long day in the shop, the Beast's hemi passed a new leakdown test with flying colors.
Still, the Beast will have new computer info available at the next race, back at Huntsville, with a new device that will give a readout on engine boost for the entire run. Also, the fuel management system will be all in for the race. "We're going to throw everything we've got at it, all the technology we've invested in," he said. If all the pieces fall into place in the next few races and the Beast starts to meet its potential consistently -- 3.90s and even high 3.80s -- Paul said he would be likely to keep his roots blower setup and forgo a switch to a costly screw blower. Nailing the torque converter configuration will yield big gains. The Beast had .098 60-foot times with its old clutch setup; Paul said the converter should drop that to .094 or better.
The schedule is Huntsville and Montgomery this month and next month, for a total of four races to wind up the season.
