Auto Racing: Superchargers and suspension, air ride suspensions, vortech supercharger

Question
I understand what your saying about running the two super chargers but i  just want to clarify about the twin turbo system are you saying that i can run both a twin turbocharger system and a twin screw supercharger at the same time on the same car and if this is possiable i was wondering if you have ever seen it done before?
         Thanks, Alex

i was wondering if you had a twin screw supercharger on a 2005 mustang Gt if you could use it with anorther vortech supercharger such as the VORTECH V-1 T-TRIM SUPERCHARGER at the same time or if that couldnt work i was wondering about using the twin screw supercharger and adding a twin turbo system to the car since it used the cars exhust if it work because it isnt run by the engine itself. my other question is what you thought about replacing the suspension on a 2005 mustang gt with Aire Ride Technologies airbags and what do you think this would do to the handling of the car would it make it better worse or around the same.any comments or tips would help.

         Thanks, Alex

Alex-

  I wouldn't recommend any type of setup that feeds one compressor into another.  First of all, it won't double the boost capacity like most people think (like if you were to run a Vortech at 14 psi into a twin screw that was set at 14psi, it wouldn't equal 28psi).  Secondly, it would create a huge problem by heating the air charge and not making as much power as a single unit set at comparable boost levels.  Twin turbos work well because they don't feed one unit into another.  Compressing the air any farther just wouldn't be productive.  As for an air ride setup...I honestly don't have much experience with air ride suspensions with the exception of stock systems.  Based on stock setups, I'd steer clear of them.  Then again, I know Firestone partnered with one of the bigger aftermarket suspension companies and produced a system that I've heard good things about it.  I just wish I could remember the name.  Hope this helps.

  Sorry for the wording...what I meant was that twin turbos work because one turbo doesn't feed another as opposed to twin supercharging like you're talking about when one compressor feeds another.  I wouldn't recommend any application where one compressor feeds another whether it's a turbo or a blower (or combination of the two).  While I know some industrial diesel applications do use a smaller turbo to feed a bigger one, this doesn't work with gasoline motors since diesel motors run at much higher cylinder pressure than regular passenger car applications.  Forcing air from one compressor to another will not only make the air charge less useful by heating it, but it could also damage your piston rings and/or head gasket since their not designed for that kind of pressure.  I'd say just find a good system (like a Kenne Belle twin screw or a good turbo setup) and stick with one compressor.  Hope this helps.
