So how many people would be interested in supercharging there cars. I have been contacting a few companys about offering products for the ls4. After all there are four different car seires that use this combo. i thnk with support from at least the GXP MCSS and ISS car guys this could become a reality. Alot eaiser install and cleaner look, and lower underhood temp. And really help the ls4 pull harder in the top end of 2 and 3-4 gears. I love turbos but i have not impressed with the setup offered to us for our cars. IM being serious about this please let me know. From what i talked over with the manufacures most want about 100-150 people interested. Most are intercooled..air to water... Which is the only ones i would be interested in personally. So let me know
