Are the builders doing that at the expense of the family? farm? bank? Seems like a lot of money for a few minutes of glory on the track. [Reply]  [No Email]

Many of the rigs are junyard parts- Six Shooter has four turbos- two pushing into two, for about 120 pounds or so of boost. I think it's the first two that came from end dump quarry truck motors into a Ford truck block on steroids. It pushes 1000 HP. The two Allisons on Hot Damn came from an old fighter, and it's the second machine they have built. This one is 'new' and has most of the bugs worked out. The first Hot Damn had both mills fore and aft rather than SXS. In the pulls, there are twelve prizes, ranging from about $50 or $60 to about $800 or so. but the big prize is points for the Nationals. More points, bigger payday later. If you really look at these rigs, there is nothing near a tractor you see in the field. The wheels leave the line at about 50 or 60 mph, and the rig hopefully has enough ponies to keep them spinning for a good chunk of dirt. Weight distribution, track conditions, horsepower and even the driver all make a difference in the outcome. But these rigs are cobbled together by some real, honest to Gawd, funloving geniuses who just like to tinker with an engine out of a junkyard and see how many more rpms they can come up with. Aircraft turbines and pistons are fun. A friend of the SIL's is working on a radial rig from a B-26 bomber. I saw one some years back that had 7 engines on it. What a driveshaft! Heckuva neat hobby- just the boys and bigger toys! [Reply]  [No Email]

It has 2 intake valves and 2 exhaust valves per cylinder. Plus, it has 2-exhaust ports per cylinder. So, you end up with 24 exhaust pipes, 12 on each side. [Reply]  [No Email]
