Want to add overdrive pulley to allen 9PSI Kit

I have an Allen Engines 9 PSI Supercharger installed on my 97 T-Bird, but because of my ported and polished heads, I am only pulling 7.8 PSI...I want to increase my crankshaft pulley by 2 PSI (I have the Cobra Crankshaft installed and ALL Manley H-Beams Pistons and Rods w/ .30 bored out)...Can I put the 7.9" SVT Lighting Overdrive Crankshaft Pulley on and call it good or do I need the Innovative West 10% Overdrive Crankshaft Pulley?

I am pulling as much torque as Horsepower, so I want to free up so torque so I get better efficiency...BTW, I have a Powermaster G3 200 Amp Alternator, but stock water pump, will the overdrive pulley cause any issues?

AED 9 PSI Supercharger, .30 over Forged Block with Manley H-Beam Rods & Pistons, Innovative West 10% Overdrive Crank Pulley, Thump RRR Tensioner Pulley, Cobra Crankshaft, BPE Racing Stage 2 Ported & Polished Heads, Crower Direct Replacement Cams, 70MM Throttle Body, MAC Cold Air Intake, 80 MM L-MAF, 38Lbs Injectors, JBA Ceramic Coated Headers, Metal Matrix Drive Shaft, Kevlar Clutch & Kolene Reaction Plate Transmission, True 2.5" Dual Magnaflow Exhaust (Cats & Mufflers), Griffin 1 1/4" Radiator, B&M Racing Trans Cooler, Hughes 2750 Stall Torque Converter, 3.73:1 Gears with Traction Lock Differential, Trans-Go Kit, Superchips Custom Tune for Supercharger, 17" SVT Wheels, Kenny Brown Suspension Enhancers & Eibrach Lowering Kit.

Spoke to Innovative West and they recommended the 7.25" 6 Rib 10% overdrive pulley. Is this what you guys would recommend? Do I need to change the water pump pulley to prevent overspinning? Do I need to change the alternator pulley to prevent overspinning as well?

I'm having the 10% put on mine, it's the 15% and 18% you have to worry about overspinning.

You will probably need to do some grinding on the front cover to use the 10%, I'll point RobertP at this thread since he's doing mine and has done them before.

According to innovative west, the 8 rib pulley will not interfere with anything and no grinding is needed, since the pulley is only 7,25", compared to the stock 6.5. Also, since I am running the 8 bolt forged crank, I was told it is an easy fit. Do you agree? Would you change the super charger pulley to an 8 rib? I am getting belt slippage, which is why I am going with a larger crank pulley and the billet tensioner.

Here's my Innovators West 10% that RobertP put on last Monday. He did have to do a bit of grinding.

The same belt that was used for the 9psi AED kit fit with the overdrive pulley.
