what’s to get? twin turbo to what looks like dual air-water intercoolers…side feed to the IM on top ---

look closer to the exhaust manifold/downpipe setup. THINK: V8. ---

header/turbo/ic/intake? red boxes are for air filters… openings below them are for ram air. black hose/pipe in front is for IC. Not sure what you’re asking? ---

I think I see what you’re asking about… the rear-most cylinders exhaust tube seems to come in at the back of the turbo instead… not sure what’s going on there… ---

Reverse rotation turbocharger on right side Both are set up to run off only 3 cylinders to reduce issues from excessive exhaust pressure. The turbines they chose were small so that is the reason for running only 3 out of the 4. And the engine is out of a ML 63 and not a CL 63 ---

are you talking about the runner on the rearmost cylinder? i think that’s just how they had to design the manifold to fit in the engine bay…if they had made it a longer, more equal length runner, they prolly would’ve had interference along the frame or with some other piece of equipment. i dont think they are “only using 3 out of 4 cylinders” on each bank…that’d be retarded and such a waste. the runner is probably just really short and feeds basically directly into the turbine housing. think like a log manifold…something like the 2 middle runners ![http://www.dragsource.com/logmani.jpg](http://www.dragsource.com/logmani.jpg) i’ve never seen a 1 piece cast comination turbine housing/exhaust mani before tho that’s pretty cool (but GOTTA be sooo expensive to fix lol) ---

to back myself up > To avoid negative effects on the system from excessive exhaust-gas pressures the manifolds are designed to utilize the exhaust from only three of the four cylinders on each side of the engine V for driving the turbochargers. ---

wow, i can understand using a smaller turbo for more low range tq and all that crap but WHY would you do that haha…such a waste of 2 cylinders. “Excessive exhaust pressures” :gay2: might as well have just used a blower i guess when its 6.3L and using tiny turbo’s you don’t need all 8 cyls to run em efficiently. ---

Ugh. Would be a pain to tune that thing. def need separate EGTs on a bunch of cylinders and cylinder based timing maps. ---
