    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 2013 stage 3 phase 1 roush. Will there be any changes to tuning, belt, or fuel system if I want to install rhe 79mm pulley?

    Hi fellow enthusiasts, anyone have a rough overview of what the difference boost levels result in overall hp gains? For example 90mm to 85, to 82 etc.? Thanks

    • Power increases with the listed boost increases will depend on a number of factors, including your tune, fuel octane, and other modifications done to your car.

    I have a 2017 5 L with the roush 2300 supercharger making 727 as advertised Believe the stock pulley is 80 mm i’m thinking of changing it to a 72 mm well I need a new belt and a tune Also what will be the boost differential or gain is it about 4 pounds .

    • The VMP Pulley for Roush 2.3L TVS Supercharger Kit (11-17 GT) with the 72mm pulley will increase the boost by approximately 4 PSI and will require both a tune update and a new belt. Fuel system upgrades are also recommended with the 72mm pulley.

    What size has the loudest whine to it?

    • The 69mm pulley will have the loudest whine. The smaller the pulley, the more whine there will be, however you will also be building more boost, and may require more modifications depending on the size you go with.

      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.

      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
