Orangeburg off

     Usually, it's a problem with the car that keeps it from racing. In this case, it's the other essential part of the equation: the driver. Paul Gibbs says he has had back problems off and on since his 20s, and on Monday it went out big time. When I talked with him Thursday, he was confident that the worst of it was over, and that he would be pretty much back to normal in a few days. He's getting more treatments for it today and tomorrow. So, no trip to Orangeburg this weekend, which would have been an interesting race from a competition standpoint (no screw blowers) and history (a return to the track where the Beast crashed and came close to burning up a couple of years ago).
    Meanwhile, Paul has been talking a lot with other pro mod folks about how they've dealt with backfiring problems, and will try a new tack: different spark plugs. These are NGK plugs Paul ran years ago; they cost $7 each, and are replaced after each run. Paul switched to a less expensive NGK plug (about $2) that offered the same performance. But the design is different, and another racer said that design can lead to backfiring. Paul remembered that the Beast never backfired on the more expensive plugs, so they are going back in. With this move, Paul said he won't change his valve spring pressure.
    When his back gets better, Paul will be back in the shop to replace a piston in the Beast's hemi (likely connected to the backfiring problem) and install a device called a crank trigger that is designed to keep the engine's timing more consistent during a run.
    So, if all goes well, car and driver will be healthy, and the Beast will be back at Huntsville in a couple of weeks. The last race there produced the best run of the year, but the Beast should be in position to better that, and maybe break into the 3's.

Huntsville recap, and a weekend off

   

    Last weekend's race at Huntsville was a pretty good one for the Cuda Beast in terms of performance and knowledge gained. Paul ran a 4.17, a season's best, to take seventh in a tough 8-car field that had the fastest cars running 3.70. He went out in the first round against the No. 2 qualifier and blew a burst panel at the finish line.
    Some of the times for the weekend were definitely suspicious, but the track assured Paul that his 4.17 was good, and Paul said he could really feel the G-forces in the driver's seat. Most interesting was a 60-foot .095, which is essential to sub-4 times. But 100-150 feet out, the tires smoked just a bit, and the Beast then hazed the tires the rest of the run, leaving two black strips down the track. So, a 4.17 with the tires not fully hooked up for most of the run was definitely encouraging.
    The blown burst panel brought back the backfiring problem that Paul had hoped he had solved with a new distributor cap. This latest episode got him to thinking about what happens deep inside the engine. He said he's never run a lot of valve spring pressure to keep from breaking parts, but the backfiring indicates that valves aren't fully closed when they should be. Plus, blower boost acts to reduce the actual valve spring pressure. After discussing the situation with his valve spring supplier, Paul said he's going to bump up the valve spring pressure for the next race.
    About the next race, Paul had this weekend's SOT event at Montgomery on the calendar, but he's passing (and weather may cancel it, anyway) it up to work on the engine and get ready for a race next weekend at Orangeburg, S.C. The engine passed a leak-down test after the latest backfire, but Paul says oil from the No. 8 cylinder indicates a ring problem, so No. 8 is getting a new piston and rings this weekend.
    Returning to Orangeburg after a couple of years brings up memories of a crash and fire, but Paul says that's all just history. The appeal of the race is that no screw blowers are allowed, which levels the racing field. More and more ADRL-spec cars are turning up at the races the Beast attends now, which means its 3.90s capability would still not be competitive. Though the payout at Orangeburg isn't as much, the chance to win it is much better without screw cars in the field.
    In fact, racing in the Carolinas next year is a definite possibility because of the ban on screws. Paul says he would be ready to go to a screw setup, but that would require sponsorship, which he doesn't have. We'll preview Orangeburg next week.        

Goin' back to Huntsville, Huntsville, Huntsville . . .

      Not exactly the same effect of the old Dean Martin lyric, but Paul and the Cuda Beast team are hoping for big hits this weekend at the Bama Nationals. The last outing for the Beast was also Huntsville, where it eked into the field and lost in the first round to top qualifier/track record holder/eventual winner Dwayne Watkins. At that race, the Beast was basically running as a six-cylinder, as Paul found blown head gaskets in a postrace engine check, with two cylinders leaking badly.
     All that has been fixed, and a backfiring problem has also been dealt with by a new, extra large distributor cap. With all of those factors cleared up, the Beast will run with its current torque converter setup to see how it takes the healthy engine. Paul said the team will arrive today and set up, and hopes to make a couple of test passes Saturday afternoon, before the evening qualifying sessions. Paul said he hopes to hit the track soon after it opens for testing and a few cars go down.
    This race is an eight-car field, and has drawn some criticism for its scheduling across two days, qualifying Saturday evening and racing on Sunday afternoon. There have been indications that some racers may pass this one up, so it's hard to say how large and tough the field will be. I'm not sure what the coverage will be online, but check the message board at www.promodifieds,us , and if I hear anything from Paul, I'll try to pass it along. Next weekend will be Montgomery and the Southern Outlaw Tour. Safe, fast racing for all.

Good hunch

    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.   

Huntsville recap

       This time last weekend, Paul and the Cuda Beast were at Huntsville, with a drivetrain all at 100 percent, a good feel for the tuneup and high hopes for some 3-second passes.  Alas, it was more time spent on the learning curve, and the realization that the torque converter, though mechanically fit, lacked the right configuration.
     The first qualifying run, a 4.49 at only 135 mph, was because the car wasn't shifting into high gear. The team went through the drivetrain and found the Lenco out of adjustment. Subsequent passes, the computer data revealed weak 60-foot times, Paul said, a best of .101 when the ideal would be down in the .0990s. Plus, the .101s couldn't even be repeated. "We had tried all the starting line procedures we could try -- more aggressive, less aggressive," Paul said, with no improvement, which all pointed to the torque converter. "We were driving right through it."
    Strong 60-foot times usually yield strong runs, so the converter is going back to PTC for a makeover, and the Beast will be back at Huntsville in two weeks for the Bama Nationals (eight-car field), and then the weekend after that at Montgomery.
    Still, the 4.49 got Paul into the race at the 16th spot, apparently when a quicker car had mechanical problems. That put him against No. 1 qualifier and new Huntsville track record-holder Dwayne Watkins, who had a new hemi engine under the hood and ran 3.70s at more than 200 mph. Paul got him at the line and the Beast ran a 4.36, but Watkins took over quickly, shutting off early for a 3.91. He went on to win the event. Paul said Watkins' new motor was a proven 3.60s piece bought from ADRL hitter Bubba Stanton, who sold it with just a 3.80s tuneup, leaving Watkins to figure out the rest of it. Looks like he's on his way.
    Paul said the growing presence of "screw" blowers may force him to evaluate his setup for next year. As currently configured, the Beast easily has sub-4-sec. potential, even high 3.80s, but the expensive screw setups are bringing 3.70s to the southern outlaw arena, so 3.90s likely won't get it done. This equipment escalation may have lots of teams trying to figure out what to do, and whether, lacking sponsorhip, they can afford it.
      We'll be back before the next race in two weeks with info on the torque converter situation.  

Cuda Beast to staging

   That's right -- finally, there will be racing this weekend. Huntsville Dragway is the site -- historically one of the Beast's best tracks -- with 16 cars going for $5,000. The field of competitors will likely be huge, and could include cars that run occasionally, if not regularly, in ADRL. The weather is looking good, though it will be hot, and the track record is in definite jeopardy.
   (FRIDAY MORNING UPDATE: Got a call from Paul, passing through Chattanooga en route to Huntsville. The plan is to try to make a test run this evening -- testing is open from 5-11 p.m.-- which would be useful for the first two rounds of qualifying on Saturday night. Paul said if he looks like he's solidly in the field after rounds one and two, he'll forgo the final qualifying round Sunday morning.)
    Paul has the transmission/torque converter back in proper working order, and is ready for his first 3-second pass. He has just one race on his new Mickey Thompson tires, but says they are by far the best he's ever run.
   After this race, here is the rest of the Beast's 2013 schedule:
   

September

Sat 14 & Sunday 15 - Bama Nationals @ Huntsville  

Fri 20 & Sat 21 - Montgomery SOT  

October

Fri 11, Sat 12 & Sun 13 - Huntsville Rocket City Nationals 

Fri 25 & Sat 26 - Montgomery SOT  
   
    September will be busy with back-to-back weekends, but they are both excellent tracks and promise exciting racing. As for this weekend, you can find the complete flier for the race on the message board at www.promodifieds.us with all of the information you need to know. Also, Brian C. should be there to provide his sterling coverage, so check the message board for updates if you can't make the race.
    Be safe, and be fast.

Next race

    The Cuda Beast is parked this weekend, and will not race until Huntsville, in two weeks. Paul said he's glad to have a bit of a break to recharge and catch up on work. If he still had a shot at the Central Alabama Pro Mod Series points title, he probably would be racing next weekend at Lassiter Mountain and Holiday Beach, but Tim Segars pretty much has that locked up.
    We'll preview Huntsville closer to the race date. Meanwhile, Brian C. of  www.promodifieds.us is at today's U.S. 43 race in middle Tennessee, so can go to that site's message board and follow his peerless coverage and some of the Cuda Beast's competition.
