(FS)- (1) OBX UDP for K-V6's

Post by JM1EC-V6 »

OBX underdrive crank pulley w/welded trigger (to prevent all they do ...) w/ 2 straps for non A/C car. 1000km

I'm selling the pulley because one of my friends bought me an unorthodox for christmas !

ADVANTAGES
-More hp (+3 - 5)
-Faster Acceleration/deceleration
-Less force is ''grabbed'' from motor to turn accesories (Alt., water pump, P/S, A/C ...)


DISADVANTAGES
-Less charging at idle (Alt. slower)
-Need to modify the oil pump case (like every pulley kit for V6's)
-Even if I made a timing mark on the pulley, always adjust your timing with an OEM pulley before installing the underdrive one; because UDP pulley diameter is smaller, timing reading is difficult and inaccurate.

All (Pulley + new straps) for $75, straps only= 40$.

I think he means the trigger wheel is welded on, allegedly some of the cheap UDP trigger wheels have fallen off.
