Written by Moore Good Ink Columbia, SC: Ram announces a new high performance clutch set for all LS1 and LS6 engines ’97-’04. Assigned with part number 98931HD this new clutch set is now available from their Powergip HD clutch series, a genre of clutch sets designed for properly geared applications with up to 650 rear-wheel horsepower. When combined with a RAM flywheel (PN 1550 steel or 2550 aluminum), this new clutch can also be installed on ’05-’09 LS2 and LS7 engines. The LS Kit: This new 11-inch clutch set includes a cover assembly and a clutch plate. It provides clamping pressures of 2,900 lb compared to 1,700 to 2,100 lb of the original, depending upon the model. The Clutch Plate: To provide solid street/strip performance yet agreeable drivability, Ram combined their 900 series organic friction material, similar to that used on high horsepower drag racing applications, with poly-coil springs in an eight-spring 26-spline clutch hub. To obtain a smooth engagement, the clutch disc incorporates the superior marcel carrier as opposed to the ageing paddle-style clutch disc. The Marcel Feature: To cushion engagement, sixteen metallic pads (eight per side) are riveted to the marcel carrier. The marcel carrier has a slight spring wave measuring approximately .020 inches. As the clutch is engaged on take-off, the marcel compresses and reduces the potential for chatter and the effects of aggressive engagement, unlike similar clutch material used on a flat carrier without the marcel wave. The Clutch Hub: Stock hubs usually feature five or six compression springs in contrast to RAM’s eight, which are urethane encapsulated. Compared to the... by admin | Jun 19, 2009 | Press Releases |
Written by Moore Good Ink Cleveland, OH: Weldon Racing Pumps has launched its new continuous-duty 1100-A flow-through fuel pump. This all-metallic design follows their successful, smaller 600-A pump, and like it, serves both carbureted and fuel injected applications. While the 600-A was designed to be quiet in operation and support 600-plus horsepower, the 1100-A is also quiet but easily provides fuel for 1000 horsepower. At carburetor pressure, the 1100-A flows 157 gallons per hour @ 30 PSI while drawing 7.8 amps. For fuel injected applications, the 1100-A generates 80 PSI while flowing 110 gallons per hour and drawing only 14.8 amps. (See attached graph illustrating fuel flow and amperage draw while under pressure.) Combinations: With fuel injected applications, the 1100-A should be combined with a bypassing regulator such as Weldon’s A120. For carbureted machines, the 1100-A should be used in conjunction with both a bypassing regulator, (like a Weldon A15 or A30) and a blocking regulator (Weldon A2046). With either system Weldon recommend the installation of two fuel filters: a 100-micron filter before the pump and a 10-micron filter after the pump. Internals: The internals of the 1100-A are contained within Weldon’s familiar stainless steel type 304 housing with clear-coat anodized end caps made of 6061 billet aluminum. The fuel-cooled motor drives the pump element by spline engagement. The pump element is located at the inlet end and is sandwiched between top and bottom 0-ringed housings made of 6061 hard-coated anodized billet aluminum. The pump element (ring, blades & rotor) are all constructed of steel, and like all the moving components within this pump they are precision-lapped.
