Question about Superchargers

[Tmack99]

my cousin and I were having a debate, it may seem like a really stupid question to most of you experts out there, but posting is the only way we can settle this.

he says that it is possible to put "2" superchargers in an e46 M3 he says it would be stupid to do it, but it is possible.

I was under the impression that only 1 supercharger can acutally fit into the M3, him and his brother both have stock e 46 M3's so I hope they are wrong.

thanks in advance for your responce :thumbup:

i dont think so.

[Tmack99]

i dont think so.

thanks for responding, i wana get someone whos totally sure so i can really rub it in his face :craig:

superchargers are belt driven. how would you get both of them
to run off a belt.

Actually... it is quite possible, but whats stopping me from putting on 2 pulleys to run 2 superchargers? nothing except for the cost and pointlessness of 2 superchargers!

Yes it is possible to twin SC a car.

[BimmerDude18]

The only way this could possibly benefit you is if you stacked the blowers, effectively increasing your boost, but a stock M3 would die from that, so again, useless but possible.

You could use 2 really small compressors(low CFM). It wouldnt necessarily be death for the engine, but theres no reason to do such a thing.

True, like the idea behind multiple smaller turbos I guess...

You can do it but there is no point. It is like wearing a couple pair of socks...just wear 1 thick pair.

actually, multiple smaller turbos are effective because it spools up alot quicker than one huge one. :thumbup:

...But lack in the top end

I have seen quad superchargers done on a 70s DeTomaso Pantera.

I have also seen twin superchargers on 5.0 mustangs.

On a BMW, I have not. Its possible im sure. You would do it the same way.

I dont think there would be any point. You could get them to both run off the belt but why not just put a smaller pully on a single blower.

[Boosted330]

its possible but pointless. the point of twin turbos is because big turbos have more turbo lag, and take longer to spool up, whereas smaller turbos put out power almost immediately, but dont put out a lot of power. when you use twin turbos its the best of both worlds. the smaller turbo kicks in almost immediately, and by the time it reaches max boost, the bigger turbo has spooled up to create its power, giving a much smoother, more powerful powerband.

superchargers are belt driven, and work from idle to redline. no waiting. thus the pointlessness of a twin supercharger. you can just change the pulley to create more boost.

Er uh 2 belts, 1 long belt?

It makes no point to run 2 superchargers since they are driven by the engine directly. Just run a different pulley combination or a larger diplacement S/C. Turbos are different, they are driven by exiting exhaust gasses. On engines with 2 cylinder banks such as V8 V6 flat6 etc you can run 2 smaller turbos off of each bank. Some have run 2 turbos per manifold s small one to take care of lag and a larger one to give that top end punch. While it is possible to run 2 S/C's int is highly impractical for the return in gains.

[E46S54DR]

2 superchargers are pointless, but twin charging is the way to go! imagine a supercharger for off the line, and turbo for the freeway! This route is to costly tho, id rather get a big as$ turbo and spool it up with some nitrous :thumbup:

You mean bi-turbo(or sequential), not twin turbo(or parallel). Bi turbo(or sequential) is a setup up that uses 1 smaller turbo and 1 larger one like your talking about.
