I have a Vortec TTrim 6 rib on a 2003 Marauder running 19psi. @5,000 RPM the Boost/Volts/FP briefly drop.
Does anyone have a 8 rib system they can recc?
It is a tite fit between the S/C bracket and the belt tensioner. A thicker tensioner will not fit and to date the tensioner has held up.
Thanks

You'll need an 8-rib conversion or a 10% overdrive damper.
