Tegiwa Alloy Underdrive Crank Pulley - B Series
Increases performance by reducing the engines rotating weight and also because they underdrive the ancillaries (a/c, alternator, p/s & w/p).
The underdrive percentage is less than 20% which still allows the engine to maintain factory specified outputs for the ancillaries.
This pulley gives a 5 - 7HP gain over a standard pulley and weighs just 0.520kg (TEGIWA) Vs 2.280kg (OEM).
Note: New belts will be required to fit this product. Power claims are made by Tegiwa.
