Hi guys! I recently bought an Edelbrock Supercharger with 3.500'' pulley. I should be around 18 psi and 900 RWHP but I'm not sure if I should go with 72 lbs/hr or higher on my LS3. My compression is at 9.4, all internals are forged, better springs, valves and valve seats, 102 mm throttle body, 3'' exhaust line and a high-performance fuel pump.

Not sure where you got those numbers but not gonna happen. With that pulley you be lucky to make 600.

Sorry, i made a mistake. Kit comes with a 3.500'' pulley but i will change it for a 2.750''.

That will make more for sure, but still not that much. Probably somewhere around 14 lbs.. and HP in the 700s.

Either way I would go bigger injectors. 850s at least.

Also this would be better answered in the forced induction section.

Edelbrock isn't the setup for 900+rwhp

Throw some ID850's or ID1000's in it.
