PRO/RACE Under Drive Damper

Pro-Race Under Drive Damper

Under Drive Damper by PRO/RACE ®.

Accessory drive systems have been made more compact on Late Model V8 engines like the Ford 4.6L and the GM LS1 by machining serpentine belt grooves on the OD of the crankshaft damper. The crankshaft damper functions as a combination crank damper and crank pulley on these engines.

Under drive dampers are smaller in diameter than stock production crank dampers which slows the speed of the accessories and reduces the HP required to drive them. Since performance and racing engine applications generally run at higher RPM, the water pump, alternator and power steering pump speeds can be reduced to save HP and still meet engine cooling, electrical and vehicle steering requirements.

Features:

  • High quality at an affordable price
  • Expertly made from premium materials
  • Built to match your exact requirements

The trick is to reduce the crank damper diameter without losing the torsion control capability required to prevent engine vibration and possible damage. The PRO/SPORT Under Drive dampers have been specially tuned to control crankshaft torsional vibration to stock production levels.

Dynamometer tests of the PRO/SPORT 25% under drive damper on a 2005 Mustang 4.6L 3V engine at Livernois Motorsports in Dearborn Heights, Michigan produced a 13 HP gain over a stock production damper.

WHAT IS TORSIONAL VIBRATION?

PRO RACE Torsional Vibration

Each crankshaft has a natural frequency. If a crankshaft is held stationary at one end and a rotating load is applied to the other end, a twisting stress is created in the crankshaft. If the rotating load is released, the crankshaft springs back past its at-rest position and a twisting stress is briefly present  in the opposite direction.

The crankshaft again springs back past its at-rest position. This oscillation continues, in reducing amounts, until the crankshaft stops oscillating. The rate of the oscillation is referred to as the crankshaft’s natural frequency.

Torsional Vibration

In the engine, each power impulse imparts a torque, or rotating force to the crankshaft. Because one end of the crankshaft resists this rotation, full-power torque impulses can overcome the inherent stiffness of the crankshaft, causing it to twist. As the power pulse ceases, the crankshaft springs back in the opposite direction to “undo” the twist. It springs back past its at-rest position and a twisting stress or torsion is briefly present in the opposite direction.

 

PRO/RACE All Steel Crankshaft Vibration Damper

PRO/RACE All Steel Crankshaft Vibration Damper

The PRO/RACE “All Steel” Crankshaft Vibration Damper has a precision machined inner bore which requires special attention prior to installing.

It is also important to note that your PRO/RACE Damper is supplied “IN BALANCE” condition, therefore, if any balancing operations are to be carried out on the engine, weight must be added or removed from the crankshaft only.

Pro Race Graham Withers is Australia’s Premier Drag Racing Champion from the 1960’s and 1970’s.

During his racing career Graham broke every outright speed and elapsed time record at every drag racing strip across Australia, and was Australian Champion on three Occasion in a race car that he himself built.

After retiring in the mid 70’s Graham turned his attention to business with the same passion, drive and commitments he displayed during his racing career.  Capitalizing on his racing experience and know how, he established a retailing operation for high performance automotive components.

Graham Withers – 75 Years Young & Still Going ……

In August of this year Graham Withers will turn 75 years young and is still heavily involved in business and his love for Drag Racing. I speak to many people who revisit the ‘Good Old Days’ of the antics that they and Graham would get up to whether it was racing to work in their ‘pride and joy’ cars of that era or at the Riverside Raceway back in mid 1960’s. Others reminisce about the days that they grew up with Graham visiting him at his speed shop in Cheltenham or watching him on the various tracks in Australia in the ‘Ampol GT’ or his funny car ‘Demons Disciple’ which not only did he race ‘aswell as other drivers’, Graham also built the chassis for the funny car. Till my next blog J.

2016 is bringing many new things to Pro-Race & Graham Withers so where do I start ? Well its already June, yes half the year has gone already….. So what has the first half of the year brought Pro-Race?

Well firstly I have had Nicole Coughlin Senior Online Producer, Institute of Online Business Pty Ltd upgrade the Pro-Race website & I will be doing weekly blogs which hopefully everyone in cyber land will enjoy! The Facebook page is going well with many lively conversations, I attempt to post one or two new pictures a week and then share to the Australian Drag Racing History & Memorabilia Facebook page.

Pro-Race has Geoff ‘Mr G’ working hard in Sydney to get us more presence in the NSW market and this will then increase our Australian market client base.

 

Murray Anderson – The Real Wizard of Oz

Outside of North America, the other great “hot spot” for drag racing in the world is the continent of Australia. For years many professional, and some not quite so professional, racers from the U.S. took advantage of the opposite seasons and traveled “down under” to supplement their incomes by match racing and putting on exhibitions during the Australian summer. It was during the preliminary stages of one of the more quirky, and ultimately ill fated, of these exhibitions that an inquisitive youngster from the country had his first brush with what would soon become an overpowering passion.

Murray Anderson moved with his large family to the sprawling city of Melbourne on the south coast of Australia in 1971. Always interested in things mechanical while growing up, 14 year-old Murray continued to tinker with old motorbikes or whatever motorized piece of gear he could lay his hands on after moving to the city. Shortly after graduating from high school at the age of 17, he embellished a bit on his technical qualifications and took a job as a Mini Minor mechanic at a Leyland garage. Ironically, directly across the road was a speed shop owned by Aussie Top Fuel legend Graham Withers, and unbeknownst to young Murray at the time, the future course of his life would eventually be charted due to that very juxtaposition of circumstances.

Looking back, Murray vividly recalled his first encounter with a professional drag racer. “It was in 1974, not long after I had talked my way into my first motor mechanic job,” he said. “Graham Withers brought an American Top Fuel driver over to Australia with the intention of putting on a demonstration on an unfinished section of freeway here in Melbourne. A major bridge collapse had left the road sitting unused for several years, and Graham thought it would be a perfect place to stage a Top Fuel exhibition. While waiting for government red tape to be cleared, he put the car on display in front of his shop. At the time, I knew nothing of drag racing; I’d only ever been to a speedway bike meeting in my local country town. During my lunch hours, I’d go across the road and just look the car over from every angle. I did this every day for a week, even bringing my camera to work so that I could get a few photos because I’d never seen anything like it. Like I said, I knew absolutely nothing of drag racing up to this time.

Australia’s Premier Drag Racing Champion

Graham Withers is Australia’s Premier Drag Racing Champion from the 1960’s and 1970’s.

During his racing career Graham broke every outright speed and elapsed time record at every drag racing strip across Australia, and was Australian Champion on three Occasion in a race car that he himself built.

After retiring in the mid 70’s Graham turned his attention to business with the same passion, drive and commitments he displayed during his racing career.  Capitalizing on his racing experience and know how, he established a retailing operation for high performance automotive components.

But Graham wanted to give back something to racing, and due to his desire for continued improvement he developed and built a new all steel crankshaft Vibration Damper for high performance vehicles.  This component later become the world’s best seller.

Graham was appointed to the position of International Advisor representing the society of Automotive Engineer (USA/Australia), in which he served for over five years in addition to managing his own successful international business as Group President of the Cyco Group of Companies.

Graham’s drive for innovation and continued improvement has never diminished.  After several years of research, evolution and testing, Graham has led the development of a new light weight aluminum MMC (ULTALITE®).
