Fuel for all—including machines with demanding appetites!

Written by Moore Good Ink Fort Lauderdale, Florida: Since Wilson’s new D-rails were revealed to the racing and performance markets last November, two new, valuable attributes have emerged. First, it was discovered that racers and enthusiasts would experiment with E85 or switch to methanol and therefore require substantially more fuel. Interestingly, even four-cylinder EVO turbo teams when they switched to E-85 to cool the charge encountered fuel delivery shortages. Compared with OEM and other aftermarket fuel rails, Wilson’s D-rails have 50 percent greater capacity. Second, Pro Mod cars and Bonneville cars and other vehicles with twin turbos and twin injectors have benefited from the D-rail’s greater volume (capacity), greater flow (gallons per hour), and better distribution. Pro Mod cars making 3,500 horsepower with two injectors per cylinder (16 injectors) feed off just two D-rails (one per side), each rail supporting 1700-1800 horsepower. These D-rails also solve the problem of unequal distribution. Often, injectors and cylinders are robbed of fuel as it rushes past the injector ports in the fuel rails, and in some instances, fuel is actually siphoned out of the injector ports.  Most recently, the D-rail’s ability to improve volume, flow, and distribution was demonstrated on the Daytona Prototypes, where engine power is strictly regulated. Whether GM, Pontiac, or Porsche motors, they all picked-up power with Wilson’s D-rails.      For further information contact: Wilson Manifolds, 4700 NE 11th Avenue, Fort Lauderdale, FL 33334 Telephone (954) 771-6216 or Fax (954) 771-3413 or visit Wilson Manifolds’ website...

Ram’s Powergrip clutch: Greater clamping pressures without sacrificing drivability

Written by Moore Good Ink Columbia, SC: RAM Automotive has extended its Powergrip HD clutch series to include a new high performance kit for 4.6 liter Mustangs, 2001-2004. Established in 1972 and one of the most knowing of all clutch makers, RAM has designed their new clutch set for properly geared applications of up to 650 horsepower at the wheels, and designated it #98951 HD. The Kit This new 11-inch setup includes a cover assembly with clamping load increases in the order of 60%-80% over stock, a clutch plate incorporating the superior Marcel carrier, and a release bearing of RAM’s own design, sealed and with a hardened face. The Clutch Plate To provide aggressive 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 eight urethane-encapsulated springs in the 11-spline clutch hub.  To overcome chatter troubles, the clutch disc incorporates a Marcel carrier as opposed to the 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 coated. Compared to the stock style, the RAM combination contributes approximately four times greater resistance to compression loadings.  The cost...
