Pumps come pre-clearanced for most connecting rods and longer stroke crankshafts. Pump weighs 7.5 lbs. The version with 30mm pressure side gears is designed for all aircooled street and race 911 engines. Auto Verdi dry sump oil pumps offer more than just enough oil flow and pressure to your race engine. With lower internal friction losses they take less power away from your engine to run at maximum horsepower. The free hp and best available vacuum give your race engine every advantage. Dyno tests have proven 3-6 hp gains on a well-sealed race engine still maintaining oil pump performance. Use this extra hp to get ahead of the competition. Housings and scavenge rotors are made of a very rigid high quality aircraft aluminum alloy. The material allows for very tight machining tolerances without distortion under maximum loads. The aluminum parts are anodized before PTFE-coating to make for better adhesion. Pressure gears are made of the same quality steel as transmission gears. They are very hard and precision ground to withstand long cycle periods. A Balanit C coating is also applied for minimum friction. The rigid construction of our oil pumps makes them very durable in any kind of racing. Auto Verdi is the leading supplier of oil pumps for NASCAR.
**Note: Case modification/clearancing may be required depending on what engine case is being used, same as with factory gt3 oil pumps**
