Can't have a hummer without a blower.

We have seen H2 hummers make over 550hp with a stage II intercooled system.  At 10-11 psi you can typically see increases of 70-75%.  The stage II system comes with a D-1SC head unit and an H2 specific intercooler.  This system use the factory 6 rib drive system.  Add $250 for polished head unit.

This system comes with a 12 month warranty and has an optional 3 year warranty for $49. 

A tuner kit, which excludes the fuel injectors, fuel system and computer tuning is available.  This HO kit uses a P-1SC head unit.  For D-1SC head unit upgrade add $450.

With map pricing I advertise these kits about as low as I possibly can.  Some kits are too low to advertise.  Inquire about pricing.
