GFB Under-Driven Crank Pulley for Evo 4-9 (2011)
Go Fast Bits lightweight crank pulley for Evo 4-9 is 20% under-driven and weighs 3 pounds less than the factory pulley. Includes a new matching belt and is a direct install done in about 30 minutes.
Vehicle Fitment:
CN9A 1996-1997 Evolution IV
CP9A 1998-2000 Evolution V VI
CT9A 2001-2006 Evolution VII VIII IX
Purchase Includes:
(1) Pulley
(1) Belt
Pulley Weight:
0.7 Pounds
Belt Part Number:
6PK1755
More Info:
Like all GFB pulleys, the material used is 6000 series aluminium alloy billet, which nets a large weight saving of 1.4 kg over the factory pulley, without sacrificing strength or reliability.
The kit comes complete with the required serpentine belt, and installation is dead easy – no specialized tools are required and it can be done in as little as 30 minutes. The accessories are under-driven by 20%, which does NOT compromise their performance at low RPM, but does help reduce parasitic losses at high RPM.
Like all GFB lightweight under-drive pulleys, the improvement to the car is felt in the form of sharper throttle response (particularly off boost), and the engine feels more willing to rev. A useful comparison is the difference between performance on a cool evening vs. a warm day, or having the A/C off vs. on.
