The Blower Shop
With the success of our 192 and 250 Low Profile Superchargers, we felt the next logical step was to incorporate the same state-of-the-art machining technique and high-quality material in the development of our larger 6-71 through 14-71 blowers. The use of this material allows us to CNC-machine it to a much closer tolerance than a cast case would allow.

Castings are susceptible to a few undesirable traits: distortion, core shifts, and porosity. Bar stock, having a longitudinal grain structure, provides a more stable and consistent property, which not only provides greater strength, but resists distortion during the machining process. Plus, this lack of porosity allows a polished finish far superior to a casting. This case, combined with our proven Billet bearing plates and front cover, produces a solid piece of machinery that truly looks as well as it works. Options, including full Teflon or O.D. strips in rotors, are available. Please call (661) 229-5483 for price and availability.

Nitrous HP Camshaft Series
Nitrous HP cams, as the name would imply, are designed to greatly enhance the performance of nitrous-assisted and boosted (supercharged and/or turbocharged) engines. COMP Cams engineers created these camshafts to pack a denser air/fuel mixture into the combustion chamber, yet still do a great job of removing the spent exhaust charge after ignition.

Nitrous HP cams feature increased duration to help optimize exhaust scavenging under boost or when nitrous oxide is used. By opening the exhaust valve several crankshaft degrees earlier, the engine is better able to scavenge larger amounts of the exhaust gases resulting from added fuel and nitrous oxide. In addition, the camshaft's reduced overlap design increases engine vacuum, a critical requirement with street-based engines where power brakes and other add-on accessories require vacuum to operate. Best of all, engines equipped with Nitrous HP camshafts sound great--the other critical requirement with street-bound performance applications--resulting from the camshaft's earlier exhaust opening and longer duration. For more information about Nitrous HP cams or any COMP Cams products, call our toll-free CAM HELP tech line at (800) 999-0853.

Demon Blow-through Carburetor
The Mighty Demon Blow-through carburetor is developed for turbocharged and centrifugally supercharged applications. With an innovative throttle-shaft sealing arrangement, this carburetor is suited for pressurized environments, and is used in conjunction with the carburetor bonnets or enclosures from all leading forced-induction manufacturers. It features pressure-sealed throttle shafts with fuel curve and metering circuits calibrated specifically for turbo and supercharged applications. Mechanically operated secondaries provide instant response. Solid fuel floats permit the use of all racing and street gasoline, as well as methanol, without the risk of deterioration or distortion under boost. Patented streamlined air entries and concentric venturii provide excellent fuel distribution and consistent air-fuel ratios to each cylinder. Four-corner idle, large float-bowl windows, IdleEze valve, replaceable air bleeds, and idle-feed restrictors make tuning quick and easy. For more information, contact Barry Grant, Inc. at (706) 864-8544, or visit www.barrygrant.com.

Pypes '64-87 El Camino/Chevelle Performance Exhaust System
High-performance Chevys need high-performance exhaust. These "header back" systems feature aluminized, seam-coated, mandrel-bent 16-gauge steel and come complete with a Pypes Siamese-design X crossover kit, a pair of Pypes mufflers (Street-Pros are standard), tailpipes, cad-plated clamps, hangers, and a lifetime warranty. The combination of Pypes crossovers and selection of mufflers delivers a perfect balance of sound and performance, and it is not uncommon to gain 25-50 hp over conventional compression-bent systems. Pypes also went the extra mile by providing single- piece tailpipes preferred for easier installation--and owners with factory manifolds can add our optional mandrel-bent downpipes for both small-block and big-block applications. Systems are available in both 2.5- and 3-inch. Pro V and Race Pro Mufflers may be substituted depending on your sound and performance requirements. Slip-fit OEM-style polished stainless tips are also available.

Pypes '67-81 Camaro Performance Crossflow System
Sometimes you have to think outside the box. With the new popularity of lowered Camaros, how about if a OEM-style transverse-mounted crossflow system could be designed for incredible ground clearance, but with an ultra high-flow crossflow muffler (Pypes Race Pro) that doesn't sound like a 747 taking off? Add the fact that the system includes the only horsepower-generating X-pipe kit specifically designed to run in the driveshaft tunnel for extra ground clearance, and you have the Pypes SGF70 header back system, which can increase horsepower by as much as 25-40 hp over conventional compression-bent systems. The system is made of 2.5-inch aluminized seam-coated, mandrel-bent 16-gauge steel, and comes with a lifetime warranty. Pypes also went the extra mile by providing owners with factory manifolds and optional mandrel-bent downpipes for both small-block and big-block applications. A variety of slip-fit polished stainless tips are also available.

ZEX V-8 Spark Plugs
For engine tuners serious about performance, ZEX has two new spark plugs custom-tailored for your V-8 performance engine. You've heard the hype about platinum and iridium. While these materials are durable, there's a performance trade-off due to their high electrical and thermal resistance. ZEX Igniter Core technology uses a copper electrode surrounded by a durable nickel shell to conduct electricity and heat over five times better than platinum and nearly three times better than iridium. The result is more horsepower-producing spark energy and greater detonation resistance. As an added benefit, groundbreaking Clean Fire technology uses the spark from three additional ground straps to super-clean the center electrode and burn off excess carbon, ensuring maximum ignition power and superior resistance to fouling.

For engines with bolt-on performance parts and computer tuning up to 400hp, the Power Tune plug is ideal. For engines with nitrous, blowers, or turbos, the Power Racer plug will maximize performance in engines up to 700hp. Available for normally aspirated, nitrous, and forced-induction applications, there's a plug available for any level of modifications you may have. For more information, contact ZEX at (888) 817-1008, or visit www.zex.com.

PN 82070 (Power Tune plug, single); PN 82070-8 (Power Tune plug, 8-pack); PN 82071 (Power Racer plug, single); PN 82071-8 (Power Racer plug, 8-pack)
