RAM’s new high performance clutch for the Corvette C6 and C6 ZO6.

Written by Moore Good Ink RAM Automotive has announced a new twin-plate high performance clutch and flywheel assembly for the Corvette C6 and C6 ZO6.  They have christened it the DirectFit StreetDual and have allocated its part number as 90-2100.   Designed for use in street applications with healthy increases in power (via blowers, turbos, or nitrous), this new clutch arrangement is a true bolt-in twin-plate replacement assembly.  Similar in dimensions to the original, its overall height is 3.0 to 3.1 inches (measured from the crankshaft flange to the finger tips of the cover assembly) and its diameter is 10.5 inches.   The DirectFit StreetDual clutch is equipped with a strong, 2400-pound clamp-load diaphragm cover, a nodular pressure ring for strength, and RAM 300 series organic disc friction material. The chief advantage of using organic friction material is its superior holding power and improved driveability without chatter on takeoff.   The clutch disc springs are also stiffer. By encasing them in urethane, their compression rate increases approximately four times that of an uncoated spring. As a result, this RAM clutch assembly distinguishes itself by not only having the capacity to handle up to 1000 horsepower at the rear wheels but also providing stock driveability.   Since this clutch has to combat greater rotational forces, steel friction backing is added (see accompanying image with call-outs).  The facing is riveted steel-to-steel, in contrast with factory non-backed facings.   To complete the assembly, the flywheel is constructed of billet aluminum and contains a ¼-inch thick steel friction insert.  This insert (regarded as the thickest in the industry) contributes sufficient mass to dissipate...

The Wilson Thrasher intake manifold: very big news for 5.9L ’03–’07 Cummins turbo diesels

Written by Moore Good Ink Wilson, a leading name in performance and racing induction systems, has expanded its repertoire and announced an amazing new intake system for all 5.9 liter common-rail Cummins engines from 2003-2007. Depending upon the state of tune, the Thrasher can generate in excess of 300 extra ft-lb of torque, or with lighter throttle use, the equivalent in fuel savings. In contrast with the OEM arrangement, this new induction system provides greater equality of air-fuel distribution, especially in the cruise zone of 2,000 to 2,250 rpm.  As a result, the Thrasher generates not only amazing gains in both torque and fuel economy but also improves horsepower output, lowers exhaust gas temperatures, reduces exhaust emissions, and improves drivability. Check out the results from the strict disciplines of the dynamometer graphs above. One graph demonstrates the gains in both torque and horsepower of the Wilson Thrasher manifold when compared with the OEM manifold, both of which are tested with a standard ECU. In the other, both are tested with an aftermarket ECU. What is more, the greater the power improvements made to this engine, the greater the performance or economy benefits of the Thrasher.  In simple terms, the Thrasher requires less accelerator pedal action to pull, tow, or cruise; therefore, it uses less fuel. The Wilson Thrasher kit contains a cast alloy elbow, billet baseplate, stainless/Viton rubber gasket, and all necessary fasteners.  Installation takes about two hours.

High aspirations for this weekend’s Rockingham Ram runners

Written by Moore Good Ink This weekend at Rockingham, NC, RAM customers in IHRA Pro Stock will shoot for the stars!  Pete Berner holds a slight 25-point edge over Jeff Dobbins and 101 points over John Montecalvo in the points standings. Berner is aiming to secure his second World Championship in the class.  He’ll have a tough battle as this IHRA Pro Stock class is the tightest competition ever.   Also at Rockingham this weekend, the final round of the $100,000 Torco Pro Stock Challenge will take place, which pits Berner against John Montecalvo for the $50,000 payday.   In Pro Modified, RAM customer Mike Castellana is trailing Kenny Lang by just 21 points and is looking to secure his second Pro Modified championship.  Castellana has been the class of the Pro Mod nitrous contingent lately, running as fast as 6.000 in IHRA legal trim.   Next weekend marks the ADRL ‘Battle for the belts’ in Dallas Texas.  In the Pro Nitrous division, points leader Billy Harper will attempt to secure the championship belt.  Harper has been a strong challenger this year, reaching the finals four times and claiming three wins.  He has run as fast as 3.92 and is closely followed by teammate Dennis Radford.  RAM: FLYWHEELS, PRESSURE PLATES, CLUTCH DISCS, and...

Wilson Winners’ Update

Written by Moore Good Ink Sunday, Oct 12, 2008: Cameron Coble not only won the NMCA Xtreme Street race at Memphis, TN, this past weekend but also claimed the Xtreme Street Championship for 2008 and lowered the track record to 7.85 @ 176 mph.  Driving his 2004 Mustang, this is Coble’s second Extreme Street championship win and third consecutive championship win for NPF.  The 41 year old Coble succeeded with an NPF single-stage direct-port nitrous kit. In common with Cameron Coble, runner-up Danny Shemwell also runs an NPF single-stage direct-port nitrous system. Sunday, Oct 12, 2008: NPF (Nitrous Pro Flow) runner Jeff Knox won the NMCA Tremec True Street events at Bowling Green, Atlanta, and Memphis and in so doing seized the 2008 championship.  At all three venues, Knox set track records.  His Nova runs an NPF single-stage direct port, single-stage plate with 15 lb NPF bottles and an NPF 2-stage nitrous controller. His was the first true street car to run in the 7-second zone. Sunday, Oct 12, 2008: John Urist claimed his third consecutive NMCA Super Street Outlaw championship (his fourth championship wins overall).  Urist, on the recommendation of his engine builder Jim Kuntz, has used a Wilson throttle body, elbow, intake manifold, and fuel rails during his remarkable three-year winning spree. Sunday, Oct 12, 2008: Using a Wilson throttle body and Billet elbow, Spiro Pappas won the 2008 NMCA Super Street championship, while the 2008 Hot Street championship winner, Charlie Booze, won with a Wilson competition-ported intake manifold.  Click image for a bigger view of Wilson throttle body and elbow.
