Lexus V8 (2UR-GSE) Pulley Combo Package

In pursuit of further rotational weight reduction and performance improvement of the 2UR-GSE v8 platform, we offer this innovative lightweight underdrive water pump pulley and standard size lightweight scavenge pump pulley combo package.

In addition to reducing rotational weight by 1lb, our underdrive water pump pulley reduces coolant temperatures at the track by reducing the water pump speed by 10%. Based on our extensive track testing program with our 730whp supercharged ISF, we have found that maintaining high RPMs at the track reduces cooling due to high-speed cavitation caused by excessive water pump pulley RPMs. Testing our water pump pulley at low speeds in summer months did not result in overheating, making this modification suitable for daily driven cars as well.
