Thinking about doing the Stiegemeier porting on my Roush blower. Anybody have any experiences they would like to share? To be honest I don't even know how to take the dang SC off ha.

I really just want the SC a little louder so maybe since I already have a +2 crank pulley I can do +4 crank instead and port which should come close to maxing out my stock fuel pump.

Ideas...opinions?

 

I used them to port mine
they ported inlet, SC and filled silencer holes with epoxy

I wouldn't go over 9-10 PSI without a BAP or custom fuel system

 

Did you think it was worth it? Yeah I'm not going past 10psi on the stock motor.

 

it's only worth it to me if you get a larger TB and get them to match the TB size to the blower inlet and port the blower at the same time.
