Which means my 3 inch pulley for the Whipple must be headed my way

 

What size pulley have you been running? I was just thinking-I know you have the single belt setup and I have the 2 belt, but since I have the custom lower our ratios are the same. How much boost are you shooting for? I am running a 2.75 up top now and see around 10 psi. I think that is absolutely all mine is going to do.

 

Right now I have a 3.5 inch. I would see 10psi on the stock 6.0 at redline.
With the new setup, i'm only seeing right at 7psi, but I havent pushed the engine over 5000 rpms yet, but I doubt it would go any higher. I'm hoping for 10psi with the 3 inch.
I think thats about all this thing can push too. I'm sure more could be made easily on stock setups, but I think our engines are breathing too well to get any more from it. I guess thats good and bad.
