        I have a 2016 roush stage 3 with the 670hp set up. What pulley do they come with from the factory and what would a 79mm work without the fuel tube and belt upgrades? Also how much more boost would I make from the stock pulley to the 79mm approx. at 10ish pounds of boost now

        • The Roush 670hp kit will utilize a 90mm pulley. Your car will not require upgrades with any pulley 79mm or larger.

        I have a roush phase 1 s/c, will I need a different belt to drop down to a 79mm pulley?

        • You will not need a different belt when upgrading to the 79mm VMP Pulley

        Helpful (1)

        Hi, when reducing from 90mm to 85 or 82 are really no tunes required? I have been told otherwise...

        • A tune is not required. However, when upgrading the pulley, we do recommend a tune.

        Can a stock 2014 block handle the boost from a 72mm pulley?

            Big power increase!

            Took about 10 minutes to install, replaced my 10lb (Phase 2) pulley...Massive power surge after 4000rpm and I can almost hear the supercharger now.

            72mm

            Purchased a 72mm pully, took maybe 20 min to switch out and made a big difference on the boost. Only complaint is I never could find what size belt I needed for the new pully which the original belt does work and with research on other websites found that for the 72 mm pully you will need a 81.5 mm 6 rib serpentine belt. I haven't put it on the dyno yet still see how much hp gain but when I do I will update
