I'm thinking about it. I would like a before and after dyno when I install the 185mm pulley. Might help folks make a decision on the various intake and pulley options comming to market for these cars.
I'm still running the stock filters that come with SL55 Airbox. I just wonder if this car really needs anymore air? It might when I install the big pulley. Perhaps when these get dirty I'll go with the K&N's.
