MEGAN RACING LIGHTWEIGHT UNDERDRIVE PULLEY: S14 SILVIA SR20DET 95-98 (MR-PY-NS14SR)
 Lightweight Crank Pulleys reduce parasitic drag placed on the crankshaft by underdriving the accesories such as Alternator, Power Steering and Air Conditioning. Underdriving slows down the accessories to use less energy from the crankshaft but doesn't slow them down to the point the accessory operation becomes effected.
Most of the power gains are produced from the lightened weight of the crank pulley. Tests show that an average of 2.7 HP is gained from every pound of weight that is reduced from the crankshaft..- Total is 3 pcs set up for this model - Light weight, 3.5 lbs in total - Made by Billet Aluminum - Increase horse power (5-8 more) - Fits SR20DET S14 95-98 ONLY |
