[Fot] TR6 Harmonic Dampener

[Joe Boruch]

 Bob, I don't know TR6s that well, but here's a different approach. Is there anyway to notch the front cross member and put spacers to move the steering rack?  On Honda S2000s it's a common practice to make the front cross member removable to make pulling the engine easier.  That did not make the change the structural integrity.  Notching it can be done without reducing integrity.  JoeB

 Hi,
After I got my frame straightened last year, I've noticed that the clearance between the ATI harmonic dampener and the front cross member and the steering rack seems tighter than what I previously had. Granted how much metal had been bent in the crash, I'm not surprised.
So, I have a question for the hive - to compensate, I plan to push the engine back a tad, maybe 1/4" or so using the "usual method" of installing a metal plate in the engine mount to frame interface. The question: in moving the engine back in small increments, will I have to "shorten" the driveshaft or is the driveshaft length (stock driveshaft and stock 4-speed TR6 transmission) already able to compensate for moving the engine back.
I'm not planning to go wild and make the car "mid-engined". I'm just looking to compensate for some "rearranged metal" in the front of the car. That and I also had to switch back to "stock" rubber motor mounts as opposed to the HD units that TRF used to sell. Else, if there's a source for stiffer stock-type TR6 engine mounts, I'm all ears. The softer stock units allow a LOT of motion in both axis of motion.
After two broken cranks this season and reviewing my in-car vids, it looks like I'm not abusing the self-imposed redline of 6000 except occasional hell-toe blips on downshifts (Hi Christian!!) that I need to smooth out. But I think the crank is hitting the frame while spinning and that's adding more stress to the snout of the crank.
TIA
