1M supercharger?

Could a supercharger be paired with the existing turbocharging units?

Why? Sorry...I'm not incredibly versed on turbo cars.. but wouldn't it be easier to...

1- swap to larger turbos
2- larger front mounted intercooler (FMIC)
3- dial up the boost
4- tune


I don't understand why one would put a supercharger on a car with turbos... sorry..

There have been twin-charged cars, mainly race vehicles. The benefit is the ability to run a large turbo with a high flow rate but without the lag.

You can do it properly with a positive displacement blower that has a clutch to disengage the pulley when the appropriate turbo rpm is reached.

True. But it's non-trivial (understatement) to do well.

As you say, it's generally used to reduce lag, such as:
http://www.greencarcongress.com/2005..._vws_new_.html
But the 1M already has small turbos and not much lag, so it's be a lot of complexity and weight for little gain (which is probably why BMW didn't do it).
Now if you swapped the turbos for larger ones then it might be worthwhile to reduce the lag, but the OP suggested leaving the turbos stock...

Could it be done? Probably yes. Should it be done? Probably no...

I'd switch out the turbos for a pair of warp nacelles.

You just made my day buddy. I'm a huge Star Trek fan. I was comparing the 1M to the USS Defiant from DS9 with one of my fellow nerdlings. He got the joke.

No it demonstrates what happens when you don't right-size your turbochargers and can't run a sequential setup.

The other thing it demonstrates is that both cars are limited by traction and comparing four-figure HP cars to 1Ms and VWs is irrelevant.

EDIT: Let's also overlook the fact the Ford GT has an extra FIVE HUNDRED horsepower. Yeah, lets chalk all the advantages up to twincharging.

It demonstrates the basic assertion that twin charging has potential

Lol


I never said it would be practical or worthwile in my opinion, just letting it be known it can be done and has benefits.

If you have to ask you are probably better off paying someone else to design your twin-charged N54.
