VMP No-Grind FEAD Kit for TVS Supercharged '11+ Coyote (Race/Heavy-Duty Version) This kit is designed to work with older VMP and Roush blower kits with the 2.3 L or 2.65 L supercharger. It replaces the cast Roush FEAD bracket and spider bracket that require grinding of the front cover to install. The race kit will provide proper belt tension and wrap for a wide range of pulleys. You may use this kit with 63 mm/2.4" up to 92 mm/3.5" pulleys. This range is accomplished with the adjustable upper idler and the long-throw tensioner (32 degrees of rotation / 2" travel). This kit includes: Billet aluminum "Bomber" FEAD Bracket with mounting hardware Two VMP-61-SM idler pulleys with 6203-2RS bearings Heavy-duty cast tensioner and billet rotation plate Ribbed idler pulley and bolt Six M6 x 14 mm pulley bolts K060815 belt .035" thick pulley spacer - if needed. A note about belt lengths with this kit: Included K060815 belt is recommended for 88 mm/3.4" and 92 mm/3.5 in" upper pulleys on a 2.65 L TVS supercharger. '11-'14 Style Roush lower intakes are 3/8" taller and may require a longer belt. You can identify this lower intake by the significant 3/8" difference in blower mounting height vs. fuel rail mounting height.2.3 L VMP and Roush blowers have a lower pulley centerline which causes the needed belt length to decrease. 2.3 L blowers often use an 82 mm/3.1" - 85 mm/3.2" pulley to achieve boost levels of 10-12 psi on pump gas. Depending on your lower intake height, you may need to go as short as a K060810 or K060806 belt. The heavy-duty cast tensioner included with the race kit has a broader range of motion, making exact belt size less important at low boost levels less than 14 psi. Smaller pulleys generate more boost and cause the belt to stretch more. At boost levels of 16-20 psi, the belt should be sized to be very tight. Never adjust the upper idler pulley to force the tensioner past the stop. A .035" thick pulley spacer is included in this kit to use if needed.
