TR-6 Crankshaft Damper Assembly (Harmonic Damper Kits):

Richard Good has come up with a new complete crankshaft damper assembly for the TR-6. It smoothes out the frequency vibrations of the crankshaft and allows higher revs and more power even on a stock engine. More information can be found on his GoodParts.com website.
"Installing this damper on my high performance street TR6 engine was the best thing I have done for it in a long time. Everything was meticulously balanced and the stock damper looked fine but apparently there were some nasty torsional vibrations going on that the stock damper could not deal with. After installing this damper the engine is noticeably smoother and the effective power range is extended by 600-800 rpm. Previously the engine could run to 6000 rpm but shifting at 5500 was about as effective. Now it pulls strong through 6500 rpm and I estimate that it is putting out at least 10 more horsepower."
The kit includes: Damper, hub, fan extension replacer and bolt, new water pump, anodized aluminum pulleys for crank, pump and alternator, belt, hardware and torque tool. It is also available with fan extension for stock fan. Damper has engraved timing marks and zinc chromate finish.


Spitfire Axles and Hubs:

These parts and additional nice pieces for the Spitfire and GT-6 are available from Chequered Flag Racing (of which the owner, Joseph Siam, is a top flight racer of Spitfires himself). Pictured below is the Axle Bearing Kit, Racing Axle Upgrade and Alloy Front Hubs. More information can be found on his Chequeredflagracing.net website.
