[s-cars] Sequential Turbocharging

[Mark Strangways]

Really it would not be very complicated to do.
Now what i mean by complicated is by design terms only.

I would first start with a custom intake manifold, small long diameter 
runners for the small turbo, and then a flap and a large volumetric are for 
the big turbo. The idea would be to set the flap with spring pressure to 
require the big turbo to overcome to open it.
Second would would involve plumbing the small turbo's turbine and wastegate 
into the big turbo's turbing and wastegate. Then one would set the wastegate 
on the small turbo to open while the compressor is still in the effiecient 
range of the turbo. Say never let it see much more than 16 PSI, therefore 
not needing a intercooler and the added space and plumbing it requires.

Let mr motronic control the big turbo using the WGFV, and I think it's all 
set.

I for one would love to have a nice wee trubo sitting in front of the 
"Frankenturbo"
There is likely only 2 that would attempt this sillyness on this list ;-)
