Kaase expands P-51 head sales to include complete engines

Written by Moore Good Ink Kaase’s Boss Nine may be the aristocrat of big-block Ford circles, but it is his P-51 that is the outstanding star. You may have thought Kaase’s ambitions for his P-51 aftermarket cylinder heads were a bold maneuver, but they weren’t. In the early nineteen-nineties Jon Kaase helped Ford Motorsports with the port design of their original aftermarket Cobra Jet aluminum cylinder heads. Approximately ten years later it was he who designed their replacement: the innovative Super Cobra Jet. Then, following the shock of finding a clause within his 15-page contract, the Detroit conglomerate precluded him from supplying the heads he so carefully nurtured. In response, Kaase, an agreeable, kindly man applied his considerable talents to his own new big-block Ford head: the P-51. It was a compelling proposition and one he addressed with much anticipation, for he had the advantage of knowing what had preceded it. P-51 succeeds with attention to valve angles, port and valve bowl shapes, and short-turn widths. Winder GA: Jon Kaase Racing Engines, four-time winner of the Engine Masters Challenge, has expanded its P-51 cylinder head sales for big-block Fords to include the assembly of complete P-51 engines. For five years Kaase has been supplying their wondrously effective P-51 cylinder heads to engine builders, both professional and amateur. Predictably, the heads have been the most persuasive advocates for extending the line to encompass complete custom engine builds. They are now available from 520 to 600cu in. “You might be able to replicate the P-51’s short turn on a Super Cobra Jet head,” says Kaase, “but there’s a chance you’ll hit water.”...
First belt system for LS engines with Magnuson or Edelbrock superchargers

First belt system for LS engines with Magnuson or Edelbrock superchargers

Written by Moore Good Ink If you ask hot rodders of their greatest disappointment with aftermarket serpentine belt systems you will often find it lies not with the system’s appearance but with its fitting. Its beauty is often obscured by the fact it doesn’t fit very well. Belt system manufacturer Concept One maintains that it is quality that has sustained their business through this economic downturn. A beguiling appearance is crucial but a system’s real potency lies in its ease of fitment.     First 8-rib forced induction system of its type.  A/C compressor moved for easy installation in early chassis. Cumming GA: Concept One has released a new serpentine single-belt system for LS engines with Magnuson or Edelbrock superchargers. Utilizing a high traction 8-rib pulley/belt arrangement, they believe it to be the first aftermarket design of its type. The chief impediment when installing an LS engine in an early chassis is the location of the A/C compressor, which is located lower right. In its original position it often interferes with chassis parts, not least the cross-member. Concept One has overcome these imminent troubles by relocating the compressor on the upper right. Created to function with all Gen III & Gen IV LS engines with Magnuson or Edelbrock superchargers, this kit provides a compact, polished Sanden® SD-7 compressor as well as a new Delphi® aluminum power steering pump. As standard equipment the pump is provided with Concept One’s exclusive billet Mini Reservoir. Also included are a cast aluminum water pump and a 105-amp polished Powermaster® one-wire alternator. Other key components include a heavy-duty tensioner and Goodyear Gatorback® belt together...
Why introduce metallic-sintered materials to a regular clutch assemblies?

Why introduce metallic-sintered materials to a regular clutch assemblies?

Written by Moore Good Ink Columbia, SC: Launched in 2010, Ram’s Force 9.5 dual-disc units are not new. What is new, however, is by combining it with their 900 series friction disc, the clutch assembly’s capacity is increased from handling around 700hp to around 950hp. These new clutches fit all popular applications, including Corvette, Camaro, Mustang, and early muscle cars. Using a metallic-sintered iron-based material that is compressed under high heat to bond it to the backing plate, the 900 series disc has a higher coefficient of friction than the standard organic materials. Thus it combats heat better and offers increased holding power. Also relevant is its light weight and that it operates with a six-spring hub instead of eight. The Force 9.5 is small and remarkably light—weighing approximately 38lbs compared with, for example, the standard LS arrangement, which weighs around 57lbs and measures 11.750in. This combination of compact size and light weight hastens engine response. The effects of faster acceleration and deceleration are unmistakable. Devised as an economical, entry-level unit, Ram’s Force 9.5 is guaranteed to meet the exact height dimensions of the original factory clutch-flywheel assembly, thus it’s a direct bolt-in fit. The Force 9.5 cover assembly with metallic-sintered 900-series clutch plate is priced around $1175 while the organic version is $950.

750 Street Demon carb adds capacity

By Ben Mozart Dawsonville GA: The recent 750cfm Street Demon carburetor’s additional capacity was created to suit more powerful engines. When the original 625 Street Demon was launched in May 2012, it was greeted with much approval—the only thing conspicuously missing, said some, was greater flow capacity. In appearance the bigger 750 looks identical to its forerunner, except for the size of its primary throttle valves, which have been enlarged in diameter from 1-3/8th to 1-11/16th. The main venturii diameter has also been enlarged. Predictably the calibrations have also been increased. The secondary throttles, which are controlled by the Goggle valve, remain unaltered. An innovative device located at the bottom of the secondary bores, the Goggle valve delivers over twice the air flow of the primary bores. It maintains an invigorating effect that can be both felt and heard. Located at the air horn is an adjustable torsion spring-controlled air valve. Its function is to ensure uninterrupted primary-to-secondary throttle response, regardless of the throttle opening rate. In common with its predecessor, the 750 accommodates square- or spread-bore intake manifolds with an adaptor plate supplied in the drop kit. It also benefits from the 625’s unique fuel bowl that is integrated with the main body. Available in either aluminum construction or in an exclusive automotive-spec composite, the composite bowl demonstrates its drivability credentials particularly in hot stop-start conditions. Because it reduces heat transfer by as much as 20 degrees Fahrenheit, it contributes to faster hot restarts. To virtually guarantee a leak-proof bowl Demon created it without any plugged passages. Reassuringly, the bowl gasket is placed above the fuel level. Perhaps the...
How to cure carburetor calibration swings with a fuel pressure regulator

How to cure carburetor calibration swings with a fuel pressure regulator

Written by Moore Good Ink It’s not generally known that carburetor calibration is often dependent on the fuel pressure that enters the fuel bowl. The higher the fuel pressure, the higher the fuel level in the carburetor bowl, and vice versa the lower the pressure, the lower the fuel level. Fluctuations in fuel pressure affect the air-fuel ratios that the carburetor meters. Though the aim is to minimize the pressure drop, maintaining constant, precise fuel level is not strictly possible. As the demand increases the level drops as does the fuel pressure. So there is a balancing act to maintaining good calibration and the chief challenge is how to minimize the pressure drop across the pump’s dynamic flow range.   What Demon found when it upgraded its regulators Initially, the work was necessary because of extra pumping performance they extracted from their fuel pumps: the 400, the 280, the 220 Hot Road, and the 220PS. Moreover, the pumps’ materials were altered to accept a greater variety of fuels, which included gasoline, racing fuels, methanol, ethanol, diesel, and so on. As a consequence the original materials used in the regulators and filters had to be altered accordingly.   But now we get to the really good bit To address the pumps’ increased flow rates Demon purchased the “Best-in-Class” regulators available on the market. They then used those targets as benchmarks for their regulators, which are formerly the BG 2- and 4-port designs as well as the original BG diaphragm-bypass breed. The first priority was to increase the diaphragm’s effective area in all of the regulators to make them more sensitive...
