2015 Mustang Clutch Upgrade:

2015 Mustang Clutch Upgrade:

The Trouble with Supercharging. Adrian Gomez, an industrious 27-year old who manages Mak Performance, a Miami specialty shop established in 1995, bought a 2015 Mustang 5.0 and with fewer than 7,000 miles on the clock installed a ProCharger centrifugal supercharger. Power instantly jumped from 376 rwhp to 600 rwhp, an impressive sixty-percent improvement for the mathematicians out there. Doubtless it was tempting to ascertain just how long the original factory clutch might support the additional horsepower, which didn’t take long to find out.

Weight Watching: Shedding 15lbs from your rotating assembly

Weight Watching: Shedding 15lbs from your rotating assembly

By Sam Logan, Images from Moore Good Ink: The chief advantage of an aluminum high-performance flywheel is saving weight. For weight savings, aluminum is the most potent medium we have available in flywheel manufacture. Take a tour of Ram Clutches’ facility to see how they manufacture aluminum flywheels and clutches for the performance-minded enthusiast. Read the full story...
How to make a Street Stock racing clutch survive

How to make a Street Stock racing clutch survive

By Freddie Heaney. Courtesy of Speedway Illustrated, Photos by Moore Good Ink: Racers frequently face the inconvenient fact that some clutch-flywheel assemblies are so light they fail prematurely, often during the taxing process of getting the car into the trailer. Curiously, most professional clutch makers agree that you quickly reach a point where the ultra light clutch unit has no advantage at all and instead its arch attribute, lightness, undermines the process bringing decreased durability. A stroke of marketing brilliance some might say! Racer purchases ultra light clutch, racer quickly destroys ultra light clutch, racer purchases successive ultra light clutch. You may think racers would resent these dubious practices, but there is no evidence to suggest they do. In all likelihood if you added a little strength to the unit you would probably gain 50 percent greater clutch longevity without any perceptible loss in power. In either case, to reduce these often unnecessary costs here are a few tips intended to prolong the life of the racing clutch.  Read Speedway Illustrated’s story...
Ovality and other guarded racing piston matters

Ovality and other guarded racing piston matters

Below their ring lands, pistons are neither round nor do they have parallel sides, instead they have a larger diameter towards the bottom, usually between the base of the piston and the piston pin hole, and become progressively smaller toward the top of the piston. This design logic allows for greater expansion of the piston crown because it’s the region closest to the heat source. Read the full story courtesy of Drag Racer Magazine...
Kaase P-38; the better Windsor performance head

Kaase P-38; the better Windsor performance head

Engine philosopher Jon Kaase (Jon Kaase Racing Engines, Winder, Georgia) had an idea, an idea that nagged. For too many years, he’d watched the ubiquitous 302 amass part upon improved part, but observed nary a deviation from the original cylinder head configuration. He thought he could produce cylinder head castings that looked like ordinary Windsor 302/351 parts on the outside but inside would be entirely different from the original blueprint. Being a racer, he knew the value of stealth. But more importantly, being an engine builder he knew the prime advantages of canting the valves to open towards the center of the cylinders and so mitigate the natural shrouding effect of the cylinder wall.

Real Racing Head Gaskets

Real Racing Head Gaskets

Current engine design is being transformed by the arrival of GDI (Gasoline Direct Injection). GDI requires high-pressure injectors to inject gasoline directly into the cylinder rather than the intake port. In so doing they improve fuel atomization, promote cleaner burn, boost fuel efficiency, and more importantly for the racing brain, improve performance. Twenty-four years ago a similar transformation took place in head gasket design when the term MLS entered our speech. The revolutionary multi-layer steel gaskets featured… View the full article as it appeared in Australia’s Street Fords magazine – click...
