[V8] Intake/supercharger

[Jeremy Ward]

This guy dropped a V8 into his 200 and replaced the factory airbox with
the following:

You could always borrow the R8 setup:

BTW, TFA lists the need parts as "NOT A SPARE PART"

Or perhaps the DTM V8 setup:

You may need a larger MAF capable of metering more air...  I wonder what
motronic would think about the higher signal...

Hey Justin...  Didn't you use a Mercedes SC on your V8 for a school
project?  Care to share info on pulley placement, air routing, etc?

... the project I was discussing on the phone involved retaining the
Ford's
intercooler setup ... seems to me that approach might allow you to use
the
factory lower IM.  The thing is that the engine on my bench still has
the
upper and lower IM in place, so I am not sure about whether or not it
would
be practical to mount the blower above the factory lower IM.  Perhaps it
would make sense to attach the blower to the *upper* IM ... it is mostly
just a plenum after all ... if that would make any sense then you could
possibly retain the Audi MAF ... and then pull the "elbow" piece that
feeds
the TBs and replace it with something to accept the inlet from the
intercooler.  Funny, this almost sounds as funky as the guy wanting to
drop
a carb on his car ... ;-)

As to the subject of auto adjusting ... sure, the engine will try to use
the
OXS feedback mechanism on the fuel side, but there would be no
compensation
in the ignition circuit.  I've got to believe that you will need to have
a
way to tweak the timing based on the manifold pressure.  I guess that
means
that we might be talking about tossing the factory control out the
window
completely ...
