A question from a mere brainstormer, and not an expert... BUT:
Why can't we replicate the design of the biturbo V12 in the SL/CL cars, but just do it with half the cylinders and much smaller turbos? Is a single turbo really the best and only method?
Seems to me that you could use two small snail turbos (like a K03) behind
each manifold... this eliminates the charge pipe issue, the 90 feet of piping, and the need to relocate brake lines. What you spend on another tiny turbo (much cheaper than larger ones, right?) you end up saving by not having to re-engineer the whole car.
Simply route a custom fab'd charge pipe into a surge tank like the kompressor motors use, only mount them backwards. Less piping, less lag, less reverse-engineering of the car.
And, I can't lie -- having a
V6 BITURBO badge on the side of the car would be a RIOT!!!
Smaller turbos = faster spooling, more space, smaller charge piping (easier bends)... I'm seeing lots of advantages.
Tune them down to where they only create 5psi each, for a combined 10 psi, and we have a safe kit that solves the charge-pipe/ground-clearance problem. Lower psi per unit equals cooler temps as well, right?
Or am I being moronic? I have way more imagination than expertise on turbos.
