    Feel the power gains yet? Should put you in the back of the seat like when the NOS button is pressed.

    So update on pulley is that the driving temps definitely drop faster but idle temps are only different by 5-10 degrees. Im happy with it overall and definitely don’t see 219 as much as before.

    How does an undersized pulley keep things cooler?

    RPM would equate to fluid flow, and flow would equate to cycle time (radiator -> engine -> radiator etc). So less flow means slower cycle times which should show up as higher temps exiting the engine.

    What am I missing here?

    Smaller pulley = more rpm when driven by a bigger pulley. So it actually increases flow which as long as the rad can shed the heat and the fluid can pickup the heat from the objects is certainly a good thing as it should keep the coolant cooler allowing for more thermal transfer from the engine to coolant
