Does anyone know if it's possible to put two supercharges on a car and they both work.? Or am I the only one that has
Wondered that.

 

Go on youtube and search "double blown gto" I'm on my phone or I would post the link for you.

 

Is it the one with two root styles? Cause that just seems like the second one wouldn't work and I'm on my phone also but I will give it a look.

 

Yes. And they both work. That car is dynoed in at 1400hp

 

Highly inefficient to stack two blowers like that though. I've seen a twice blown lightening.

 

I just always figured it wouldn't work.

 

Yeah I've seen that vid, that L is pretty sick.

 

The sky is the limit but your talking about diminishing returns except for the WOW factor (the caveat being if 1 blower cannot provide enough air and you have to use two, but I cant think of a single case where that would be the case).

 

Why double supercharge when you can twin turbo to produce the same or more HP?


I know TBone will be all over this..

 

Twin supercharger would be hard to fit under hood. Twin turbos are easier to fit. Two blowers equals twice the scfm which is what matters with forced induction. PSI is not as important as scfm.

 

2 seems silly...just get a bigger one.

 

Pete. Read below lol

 

Yeah, just think of all the horsepower that would be required to turn two positive-displacement superchargers, not to mention all the stress that would be placed on the engine's pulley system, etc! Twin turbo would definitely be the way to go, IMO!

 

Its the " wow look at me" factor just like feeding a supercharger with a turbo. just a get a quality supercharger kit or turbo setup and the real car guys will know what you got. just make sure if you get well into the boost you get a stout block,quite a few triple digit cars in my area w/o the need of a two superchargers or some ricer set up.

 

It has been done. IIRC, there was a Fox Thunderbird a while back that had a 351 with two Eaton-style superchargers running parallel vs. the tandem or "stacked setup". Ran in the 10's. http://www.toohighpsi.com/SCTC/sctc.htm
Think a twin Procharged vehicle is out there too. There is even a twin Rotrex supercharged Ferrari. http://blog.titanmotorsports.com/?p=1915
The granddaddy would have to be a twin turbo + twin supercharger setup as seen on this GT-R. http://www.streetfire.net/video/twin...gtr_694976.htm Why? "Because racecar"!?
But, after all is said and done, rather just go with a properly sized twin turbo and be done with it.

 

It's possible to run twin centrifugals but there is no point in forcing anything into a twin screw. A positive displacement blower will only blow what it is capable of.

 

Took this a few years ago . . . can't remember what it was going it. I think a GT350 . . . or a '67 GT500 . . . really can't remember. Was taken at Paul's Automotive Engineering (PAE).

 

that is cool!!

 

Looks like a dialed-down version of this: http://jalopnik.com/219173/
If you can find a clip of Bill Cosby talking about his "sister car" Shelby built for him - it is hilarious.
Except I think the 2nd owner totalled it. Supposedly Bill was too scared to drive it on a regular basis. Twin Paxton SC'ed 427 + short wheelbase? I wouldn't blame him.
