Custom Twins Set Up
I was watching Top Gear the other day and in the show they had the new M5 BMW. The motor had a twin turbo set up and with the setup it had a small turbo then a laarge turbo. Is it possible to create a setup like the M5 and if so will it really cut turbo lag?

Wrong. We call them the twins because both turbos are exactly the same.
That is what the sequential system is though, one turbo for quick spool, and both for higher end power.
And what M5 has twin sequential turbos? They have V10s. 335s and 535s are twin turbo.

well thats cool. Would you benifit that setup if you used a larger setup like a gt35r then a gt40r turbo setup. I see alot of people doing a single turbo setup and having some turbo lag probs. I know this would cost more money in the long run but sounds like it would have more benifits than a single setup.

well now adays its pretty much normal consensus that a good, well made and well balanced single turbo can out-do pretty much all twin turbo's
thats why everyone goes single

As a current owner of 4 BMW's and previously having 14 others, BMW is clearly well past its prime and a decade past anything like making Ultimate Driving Machines. I did think the turbo diesel 5 and 3 series I drove last year were interesting motors (in overweight and over-computerized hulks that only young BMW newbies who never drove any of the REAL BMW's could ever like and disgust me... but how do you really feel, Gordon).
The idea of ruining the V10 by turboing it certainly fits BMW's current swirl around the toilet bowl. Another yeah you can do it, but why would you? If the 5 series weighs 3800 pounds and just can't cut it with a lousy 500 hp engine, lighten it the hell up. But, no, they have to compete with the equally stupid and fat Audi's and Mercedes. They turbo'd their motors to get their crappy V8's to have enough power to compete with the amazing BMW v10. Now, BMW goes the other way. They couldn't get me to buy one of these trucks if they paid me. They probably offer iDrives that warn you of impending oversteer in a whining German accent.
Many people point out that BMW pioneered the turbo in the 1974 2002 turbo, which was a very cool predecessor to the 1975 Porsche turbo. Both, of course, copied the 1966 Chevy Corvair Monza Corsa turbo, the killing of which was Ralph Nader's earliest contribution to the downfall of American sports car innovation and which led him down the road to endless boring sick greenish (made me turn a sickly green) presidential candidacies to this one. So, God knows they have a right to add 2, 3, 4... turbos to the V10.
The new twin turbo motor in their new uber sports model will top 250 mph, which is clearly just the thing we need for the commute into New York or a quick drive up Highway 1 on Cali. Perhaps these cows of the road will come with the horns that warn one Carnival cruise ship that its coming within a mile of another when berthing?
So, yep, there will be a twin turbo V10 Bimmer...

That turbo setup does indeed work similarly to ours in concept.
I totally agree with Gordon's rant on BMWs.

iv got a 208kw jdm twin turbo subaru.
It has a sequantial twin turbo setup with one small and one large turbo.
there is quite a big "dip" in power at the transition between the two turbos - my rx7 has a far smoother more poweful transition to both turbos then the Subi.
Although engineering obviously has alot to do with it, i think a smoother transition is possible with two turbos of similar size rather then one big one small.
its very complex to spool a larger turbo enough so its able to take over from the smaller turbo with no lag/dip and keep a smooth transition.
