Roush pulley sizes
Hi gang. Has anyone tried the different size pulleys on the 2015 Roush 670 hp kit for a 2015 GT? I have a 2015 GT and just had the Stage 1 670 hp kit installed along with BBK high flow cat headers and 3" x-pipe and exhaust on Roush axle back exhaust. I am at 9psi on the factory 85mm pully and am wandering what gains could be made with the 82mm-79mm....anyone try this on a dyno?
Thanks
Jeff
