| Dual Superchagers?
This is the first time I have ever seen this before. Is there any horsepower gain over just a single supercharger? http://www.youtube.com/watch?v=LdQd5K5lEuI Justin |

I've seen twin blowers, but never stacked on top of each other like that... Probably more show than go. I doubt he's running a whole lot of boost with that setup...if he were they'd likely blow themselves right off of the engine, and if you notice, there are no blower straps on it either. So yeah, more show than go. Looks cool though! I always wanted a car with a blower like that. |

I prefer Turbochargers... 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. |

That's what nitrous if for 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 | |

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. Quote:

No, nitrous is for the budget minded AND a simple way to get off the line with a huge turbo. Well that's pretty sad considering there DSM's with singles making more than that (power). If doubling up on FI was that effective everyone would be doing it. For EX- if I remember correctly, most people that have TT Supra's and want high HP actually ditch having twins and go single. I believe this is the case for RX-7's & GTR's as well For racing apps, at least at this time, singles are more effective than twins. | |

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. | |

| Not true I can fill my bottle for $40 and add anywhere from 125-500hp. All with a set up that cost under $300! Can you do that with your turbo or super charger? Nope! Not everyone can afford a turbo or SC.....All said and done you will spend $2500-3500 for your setup.....And as far a tuning a car and nitrous, let me see you put a 300hp+ nitrous (Wet) setup on a car without tuning it If you are running a (Dry) kit then yea it's just 5 minutes and your done.....

I agree with your first paragraph Well I wasn't talking just about Supra's. Rex's & GTR's I don't consider much as "dyno queens", and most people go the single route for those as well. Bringing a non-driving SOB into the picture wasn't part of the topic of discussion. Show me a TT Supra that does run the same numbers as a properlly set up single. The Bugatti is also more than 6cyl. Actually I think it's more than 8...and 10...ha ha. VW has a simular version w/ a W16. That's 16 cylinders. | |

| There's never been a stock WRX with twin turbos. Quote:
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. Quote:

If you want to build big horsepower with a roots style blower there's really no need to do anything except go bigger and overdrive more, a roots on a roots doesn't make a lot of sense. | |
