DESCRIPTION
Want MORE power from your MP62 supercharger kit? This 2.8 inch pulley is a direct replacement and bumps the boost up to about 12 psi. Same pulley we used on our Silver NC to hit 262 HP on pump gas with our built 2006 motor and we continue to use it to this day for over 300 HP at the wheels with E85 fuel.Pulley is made from hard anodized 6061 T6 billet aluminum.
Includes a new accessory belt in the appropriate length for this smaller pulley for cars with A/C and power steering.
Fits MP62 supercharger kits.. both ours and the other guys'.
2009+ motors can handle this increased boost pressure. We do NOT recommend adding this on stock 2006-2008 motors due to the weaker internals.
Re-tune is REQUIRED.
Higher boost means you need more fuel. But not to worry! The injectors in our MP62 kit are sized large enough to supply the required fuel even for this boost level, with just a re-tune. If you wish to run E85 fuel along with this smaller pulley size, you'll need larger injectors and fuel pump.
