How to keep your poise when installing a gearbox with an upgraded clutch

Installation Tips from Ram Clutches: Disengaging the quick-connect feed line when installing a new clutch system with an existing internal slave cylinder/bearing, ensures the bearing assembly remains partially filled with fluid. As a result the release bearing compresses against the clutch fingers as the transmission is being installed and requires more force to slide it in place than desirable. To avoid this hardship, alleviate the unwanted pressure by reconnecting the feed line before sliding the transmission fully into position. Thus the fluid trapped in the bearing can now return to the master cylinder. As the transmission is installed the bearing is preloaded into place.

First upgraded dual-disc clutch for 2010-‘13 Camaro

By Archie Bosman Photographs by Moore Good Ink Columbia, SC: Alas, there is no pilot bearing in the crankshaft of GM’s V6 Camaro 2010-‘13. The input shaft ends where the clutch splines begin. But to create an upgraded dual-disc clutch assembly, one that is capable of transmitting 700ft lbs of rear-wheel torque, Ram Clutches made fundamental changes following their initial tests using the original layout. Fundamental Changes First, to support the input shaft they invented a 26-spline bushing integrated with a needle roller bearing and incorporated it at the center of their new aluminum flywheel. This acts as both a pilot bushing and an added support to prevent excessive motion or run-out in the input shaft. In addition, Ram incorporates sprung hubs in both clutch discs with six springs in each. The extra springs reduce transmission noise and any harmonic concerns; they also provide the added cushioning for a smoother drive. Higher Clamping Forces Known as the Force 9.5, Ram’s new dual-disc system provides a clamping force of 1,800 to 1,900lbs without discernible increase in pedal pressure. Perhaps more importantly, the pedal feel is more linear and consistent than the stock arrangement. Finally, weighing 37lbs, this flywheel-clutch assembly tips the scales 13lbs lighter than the original. Even more appealing, because attention was paid to the installed height of the original clutch this is a direct bolt-in. Complying with SFI standards, the price of Ram’s Force 9.5 starts at $1100. For higher torque capacities, it is also available with Ram’s more aggressive 900-series clutch discs at $1175.   For further information contact: RAM Automotive Company 201 Business Park Blvd. Columbia,...

Best and worst aspects of HTD belt-drive systems for racing engines

Best and worst aspects of HTD belt-drive systems for racing engines

By Bertie Scott Brown Photographs by Moore Good Ink Kennesaw, GA: KRC Power Steering employs an ingenious locking system for HTD (High Torque Drive) belt-drive pulleys: it is called the R-Lok. The R-lok accommodates an adapter, a series of pulleys—HTD or Serpentine or V-Belt—and an end nut to interlock with the harmonic balancer. The advantage is that all components share a common axis with the balancer, each one registers precisely. In addition, part # KRC 38140500 as shown here, allows all the components to be secured by a shorter than normal bolt for added strength. Thus the need for keyways and keys is eliminated. When secured in the recess of the harmonic balancer, the black register hub centralizes the pulley assembly and in turn holds the damper in place. The red adapter is secured to the balancer by three bolts and the remaining HTD pulleys are secured to the red adapter. The end nut allows the engine to be turned over. Equally interesting from KRC is the emergence of the C-Lok. This is a clever, quick-lock device created to secure pulleys to dry-sump pump shafts. Devised in the form of an expanding collet, the C-Lok expands in the bore of the pulley while simultaneously tightening onto the shaft with just a few turns of its hexagon nut. C-Lok: Gone are the ancient keyways, keys and setscrews that risk becoming seized or scarring the shaft when tightened. The principal advantage of KRC’s unique 17-spline pulley drive featured on their power steering pumps is its convenience: pulleys secured by a nut and washer slip off with just the touch of finger and thumb....

Atom race season opens at VIR.

By Freddie Heaney Photos by Moore Good Ink TMI Autotech recently hosted the opening races of their 2013 Spec Race Atom season. Using the 1.650-mile South Course at Virginia International Raceway, twenty-two Atoms took to the track. In Saturday’s first practice session Tyson Bytzek recorded a 1:12.947—the fastest time of the weekend. Christian Shield and Frank Ward completed the top three slots. On the second practice session, Bytzek again ran the fastest time followed by Shield and David Chen. But on Sunday’s qualifying Chen claimed pole position, one tenth of a second separating him from Bytzek.  In Race One, David Chen set fastest lap with a time of 1:14.550 while Bztzek took victory. Chen, Shield, Bruce Duff and James Williams claimed the remaining podium positions.   In Race Two, Christian Shield triumphed ahead of David Chen and Bytzek. James Williams and John Williams drove to 4th and 5th places See practice, qualifying and race results at: http://www.mylaps.com/en/events/906921 Afterwards Tyson, who set fastest lap in race two at 1:14.38, said “To me, the best part of racing the Atom is its seat-of-the-pants driving sensation.”   “For my birthdays, I’d treat myself to two racing weekends each year, the total cost of which was around $10,000. Not surprisingly, my Spec Race Atom program gives me a lot more racing for a lot less money.” Brian Yates   Tyson Bytzek (40) enjoys a busy career and is not always able to devote unlimited time to the sport, so the Spec Race Atom series has been the perfect balance. “I knew if I didn’t do this now I would never race, he says.
