Chuck, If, or (when) I get around to converting my 88 Red Devil to 4 link, is it mandatory to relocate the countershaft from rear of engine to in front of the engine, like your old car is now? And if it is mandatory, why so? Inquiring minds...... Bill Schmidt 88 RD Kawi
>>> "Chuck McAbee" <[EMAIL PROTECTED]> 04/02/07 3:03 PM >>> First question - What is the distance between your Jackshaft and Final Drive gear. On my 86 Red Devil, in it's original configuration the drive and driven belt gears were almost as close together as was physically possible. With this near mounting of the gears, the belt had no more than 3 or 4 teeth of engagement on the drive gear...in racing this was no problem, unless I spun and then tried to stand on the throttle while still rolling backwards. For 2 seconds it sounded like a Ferrari at full song, as the teeth were ripped off the belt. The same Ferrari sound would occur at an Auto-X, for the same reason....trying to pass too much power through too few teeth of engagement. Once the car was converted to a trailing arm, 4 link rear suspension and the drive gear and the driven gear were separated by about 22 inches (which required a longer belt, just slightly less than 1/2 of the drive gear was captured by the belt and thus had 15/18 teeth of engagement and I never had another drive belt problem under any circumstance.

It broke somewhere near the start... I'd guess on a rational level that it broke on the launch, but I swear I had power for at least the 1st 20 feet, and I did get up enough speed to coast well off the course. Anyway, I have a spare belt, so I can replace that, but I'm wondering if there is any autox specific trick that should be employed to keep this from happening again. Different tension? Driver adjustments?
