GFB - Go Fast Bits 2220 Gfb Pulley Kit
GFB - Go Fast Bits 2220 Lightweight Crank Pulley
GFB lightweight pulley kits are made
from aircraft-grade 6061-T6 aluminium and
offer faster acceleration through significant weight reduction on
the crankshaft. The effect is similar to a lighter flywheel, and
the car feels more lively and willing to rev.
Most of our kits are underdriven, which means the accessories
are driven slightly slower to reduce parasitic losses. It should be
noted that our underdrive pulley kits do NOT adversely affect the operation of the
accessories. If they did, we would not sell them!
- Improved throttle response and acceleration through significant
reduction of rotating mass
- Engine feels more free-revving
- Under-driven kits offer more power through reduction of
parasitic losses from the accessories with NO adverse affects on their operation
