I think each exhaust primary has 2 outlets (1 to each turbo). Looks very complicated. Surely it would have been easier (possibly not as smooth) to have the 1st and 3rd ** cylinders in the cycle to 1 turbo and the other 2 to the 2nd turbo. I still don't get it really If you send half of each exhaust port to each turbo surely you are lowering the pressure driving each turbo - when the small turbo is trying to spool half of it's "driving" exhaust gases will be wasted to the big turbo Scuderia emailed on diesel compounding turbo's for 60psi + plus boost which is the exhaust of the first turbo feeding the second turbo used on US tractor pull and race trucks. One turbo feeding it's outlet of intake air sraight into the "front cover" of the next turbo which compresses it again to make very hi boost levels. or maybe he is planning a valve system like the supra OE http://www.max-boost.co.uk/max-boost/supra/turbo.htm

Who says they are 2 different size turbos's, they look the same size to me, i cant see it working very well running one turbo into the next turbo, its probably a simplified version of what lancia did in the late eighties with the ecv triflux engine look here http://farm4.static.flickr.com/3221/2679058841_0196f9e5ce_m.jpg

1 little turbo for low down revs and torque and a big 1 for higher revs and even more torque just like the 3.0 twin turbo BMW 535d

1 little turbo for low down revs and torque and a big 1 for higher revs and even more torque just like the 3.0 twin turbo BMW 535d It is very hard to achieve that sequential boost pattern properly, and when you start to run high boost the transition between the turbos is a nightmare. I would never even consider trying to get that to work if you were designing the system from scratch. Single turbo is the way to go - Simpler and less to go wrong, more space in the engine bay etc. I can't think of one highly tuned car that used / uses sequential turbos...
