SL55/63/65/R230 AMG: V12 Biturbo & V8 Biturbo Cold Air Intake Clinic...
The new V8 Biturbo has same problems, Brabus is currently modifying BOTH of these engines w/giant composite CAI piping leading out of the engine bays, thru what appears to be NOT the front of radiator where OEM holes are located but the front fender wells which are perfect areas to collect fresh cool air.
In following pictures you will clearly see what I'm talking about, also watch this Brabus video..
They go thru a bunch of current 65/63 engine builds noting how Brabus was avidly researching what the main bottleneck in power was for these engines & found it is the Air Intake systems (really
) they note on the V8 Biturbo they gained 50hp by not only changing the air intake path to fender wells but by drastically increasing cai piping diameter ALL the way to turbo inlets like I have done etc..They obviously ditched the Ram-Air hood system that fed the turbo inlets on older 65 models & opted to add the hood scoop purely to vent some of the hellish heat these beasts give off.. They show 1 of the older V12 Biturbos being tested on engine dyno w/old Ram-Air system in place, obviously ALL the new V12 builds didn't retain this design meaning the new CAI's in pix make much more hp/tq..
Anyhow food for thought gents, rollup those sleeves and build yourself a real CAI
New V12 CAI piping

Hood scoop galore

63 engine w/new CAI etc

Showing larger CF piping routed all way to turbo inlets

31.5.-1.6.2014 we also see a new round of Moscow Unlim and I know of a Renntech E63S with special bigger Turbos which is going to run there with a Brabus E63 850. Regrettably they will only run 1000m instead of a whole mile, but this will be very interesting and I am also very curious how the new Brabus 850 will run in a real world race.

So why do people put cone filters and the like under the hood where
all the heat is. I tried an experiment, my Cosworth has a cone filter
where my air box used to be, I was advised by a tuning company to
go back to my air box with suitable filter, K&N in mine. When I put
the air box back I noticed a square pipe coming from the bottom of
the box about 4 inches long, and it lines up with a hole in the front
allowing fresh air to enter. Checking my boost gauge has shown I have
a little more boost and he hold up longer. It's also quitter. And Yes it goes
better, but for obvious reasons I cannot quote extra BHP figures, maybe
just a little but the way it hold the boost means more bhp for longer.

I think I'll scratch my head a little and dig deeper into this over the winter once the CL is in hybernation. Who knows, I might bring it down to BIP and let them experiment with it and see what they can cook up.

It's easy to get air to a Turbo when you have the room these big 6x6 have.
There isn't the room under a 65 bonnet, and fitting cones under the bonnet/
hood I think is worse than the standard system which takes air from the front. What I think to do is beef up the standard pipes from the front.

Then craft ram air NACA ducts in the hood that would seal to the existing air box once the hood is closed
Not sure how to keep water out but the old muscle cars ram air hoods worked great so there must be a way

If you do manage to test it with the old head lights let us know. As for me I'm just sticking with my short rams until the body kit gets put on this winter with the new headlights
