On a bone stock 4AGZE this should raise the boost to around 14PSI. If your engine has a much larger intercooler, you will not see quite so high boost pressure, but you will see much more power.
They weigh in at nearly 70% lighter than the factory pulleys. The keyway boss is 200% larger and reinforced to help prevent the keyway breakout that is so common on high revving 4AG’s

    Hello from Colorado! I have a question about this crank pulley! I have 1988 Toyota MR2 SC that I’m restoring and currently have unknown aftermarket crank pulley. The belt chirps bad at full boost and I’m worried it’s also not a true harmonic balancer. Is this product consider a true harmonic balancer? My biggest concern is the unknown main bearing damage and wear that the4agze already has from the current pulley. After rebuilding the long block I don’t want to put a aftermarket crank pulley on if it is not a true harmonic balancer. Can product create more boost and serve as a harmonic balancer? Thank you!
