This is a 175mm pulley and on a stock motor, it should increase boost to about 14psi. On modified cars, the boost will be less, but hp increases should be excellent.
We have these in single row and double row, in red or silver. They weigh in at nearly 70% lighter than the factory pulleys. The keyway is reinforced to help prevent the keyway breakout that is common on high revving 4AGs.
Tech note: Timing pointer must be moved outward due to the large pulley size. You must use an idler pulley from a NA 4AGE.
Pulleys are available in SILVER machined finish, GOLD anodized finish or RED anodized finish.
