Re: Jensen Healey Race Shakedown.....and Failure

I think the motor is fine in this case. As far as the diff, no, that didn't cause this issue I don't think. I know guys that run those on track with much more powerful cars (just read Mark Donahue and crew were running welded diff Hewlands in some of their cars back in the day) and say they are dead reliable, and this one was done by a fellow that has done many, many, many welded diffs. There is something funny up with the transmission/driveshaft I think in this case. More inspection will reveal the answer I think, but for now that joker is staying on the trailer. I don't know if I want to rebuild the car or not. Sort of down about it right now, but that might pass.

Part of the "problem" I have in not getting excited about it was performance. This car has to compete with some serious machines in ITS - second gen RX7s (and if you don't know what Mazda has been up to for the last 20 years, as I didn't, you'll find their "average" sports cars are fantastic racers), BMW 325s, Z cars, etc. - and I'm not sure it can. The motor build is a serious build and is IT max legal, but she's about 25 to 40 rear wheel hp shy, at least, from being in the hunt on power to weight with the class winners. And handling was "okay" out of the box, I know it'll get better with development, but I don't know if it'll get to the levels it needs to be. Have to think on it.
