Though I see some are making Turbo + Super charged systems. The Super is small and for the bottom end to prevent the lag of a large spooling turbo. Then the large turbo spools in and some sort of bypass in the supercharger opens for the much higher psi turbo boost.

Big single turbo & a little spray is the way to go.

Turbo + SC set ups are for show...as are twin SC's like the OP:roll:

The supercharger on top looks like it is underdriven, you can tell because the pulley is smaller than a crank pulley. That one is making some boost.

The pulley on the lower supercharger is quite big, almost as big as a crank pulley so it is prolly not adding much boost.

It certainly could be adding boost though.

I agree that this is prolly more of a show setup and not necessary. Either one of those superchargers should be able to provide plenty of boost on their own.

There are some turbo/sc cars out there that are total monsters. A guy in my old DSM club has one that throws down 32 psi at 2400 rpm with a 2.3l 4 banger. If I remember right, he's somewhere around 500ftlb & hp...but don't quote me on that one...

Twin sc's can be effective too, just not with double stacking like in the op.

For racing apps, at least at this time, singles are more effective than twins.

This set up does require alot of plumbing and most likely a single external waste gate to equalize the boost.

Remember most Supras are Dyno cars now, no one cares about lag on a dyno run to "impress". They can build retarded power, but most people lack the skill to set them up to run a 1/4 mile.

Simply put...Bugatti got 4 to work well on the Veyron and that is no slouch in any manner.

Check my original post. There's another import "god" that goes by that name...;-)



Again a Twin Turbo Supra stock has 2 small twin turbos in sequential mode. Now many thought "hey throw on 2 monsters", sure thats not as good or easy to overcome lag.

Popularly known as the 1994+ MKIV Supra, as in Mark 4, its twin turbos actually operated in sequential mode instead of the more common parallel mode. The sequential setup featured a pair of small, equally sized turbos. At first, all of the exhaust is routed to the first turbine for reduced lag. This resulted in boost and enhanced torque as early as 1800 rpm. Approaching 4000 rpm, the exhaust is routed to the second turbine for a "pre-boost" mode, although none of the compressor output is used by the engine at this point. Approaching 4500 rpm, the second turbo's output is added to the intake air, and both turbos operate in parallel. Most cars which are advertised as "twin turbo" operate by having the two equally sized turbos constantly running in parallel; the turbos spool up at the same time. The sequential mode provides greater low-end response at the expense of top-end output.




I don't at all see how this proves that TT's are superior to singles. I understand how sequentials work, and the reason is b/c it's a factory thing. Don't think you could put much of a warranty on a 1000hp factory car. Plus there's probably not a lot of people that would want to buy/drive a brand new car that has no power until 8-9k rpm (No S2K jokes:))




Ummm Bugatti made the W16 motor for VW, since they are sister companies or Audi. Again it works in sequential mode (2 per stage but the same purpose).



My bad, not as familiar with the Bugatti & had no idea they were sis corps. Me and my ignorant ass:roll: Point was it's a much larger ci/disp engine.
