Product Description
New from GFB is the Under-drive Crank Pulley for the Mitsubishi EVO
IV through to IX. 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
