When I talked with Brandon about a month or two ago about running his S/C pulley with my 178 crank pulley, he said it create's a little too much heat and wouldn't advise trying to do so. The more boost you have the hotter the the air, so the ECU will start pulling timing & start dumping the fuel to it to try to cool it down. So that being said, I think you would loose performance trying to run them together.
