Hey Guys,

We are in the development stages of a forced induction system for the new 3.7 liter. I can't say what type of blower we will be using at this time but I will say that there will not be any hood modifications required.

In regards to our current supercharger offerings for the 3.5 liter engines. Technically speaking they are beautiful and we get nothing but compliments. Our goal was not to be the most powerful kit on the market. Our goal was to increase the power safely and affordably and maintain a street legal kit. Roots type superchargers such as the one that we developed for the 3.5's are fantastic for low RPM and daily drivability. Centrifugal superchargers such as the Vortech kits will be capable of reaching higher horsepower at higher RPM but they do give up a little at lower RPM.

Everything has its purpose and top power should not be the only thing that makes a part great. It also depends on the use and function primarily.

Oh and to answer the question "why are turbo's not legal in California?" It's due to the catalytic converters. Basically, part of the emissions testing for CARB is to see how long it takes to heat up the catalytic converters. If you install the turbo's in front of the cats then the turbo's act like big heat sinks and soak up all the heat. In order to heat up the cats you have to get them hot within 60 seconds (not sure if that's the EXACT timeframe, but I know it's very close to that.) Of course, if you mount the turbo's behind that catalytic converters so that the cats heat up quickly then you now have a giant blockage in front of the turbo which will hurt your performance.
