So 74mm SC Pulley is what?
Anyone took the difference in Superchargers into account. The newer Partnumbers with "580" in the end produce more boost from factory.

None of the charts have a 74 sc pulley. Mathematics would put it in the range of a 185 crank pulley. You would want/need bigger injectors and better cooling. 77/180 is as big as you should go on stock injectors and aftermarket h/e and small reservoir. Even then you can't do back to back runs without heatsoak. Trunk tank,meth or KIller chiller and you would be better off.

Also some member have added another H/E Infront of the radiator and have had good results. Frozen boost has some small ones that would work well for this. It adds more volume to the system also. I'm going that way this summer. One is 5.75 by 11 by 2inches for 59$
