N/A Redline

N/A Redline
Hi,
Also does anyone find it odd that the redline for the 5.5 is 6700 RPM and peak power is at 5750? The Kompressor motor makes peak power at 6100 rpms, and redlines at 6500 rpms. Basically what I am thinking is that perhaps mercedes built in 'room' to grow for HP. Basically if you make the same torque you where make at 5750 rpms at 6500 you would make 415 hp. Granted you would loose torque at lower RPMS but the CLK also has 3.05 gears.
Basically what I am thinking is that if the merc heads flow well enough you could just get a cam made and move the power band out? Anyone know how well the heads flow? I figured you need to change the exhaust.
If someone where to get a custom cam made for there car would they need to get the ECU customized or would just get it re-powered with something like a powerchip work? My understanding is that its a mass flow and it should deal with the change in airflow?
Sorry for the rambling ...

Problem with the Kleemann cam is it's optimized for a SC engine, where reduces overlap from the stock cam. In a NA build, you want to increase overlap from the stock cam.
I'm leaning towards a centrifical SC kit for cost & quietness & just the hi-rpm boost (WOT gains). The 5.4L running with the ignition retard set to RON93 through the Star Diagnosis Computer gives me pleanty down low; have to dance to keep traction. Need some help up top with this engine.

Anyone one know about how well the heads flow? I'm assuming that the 2 intakes flow alot better then 1 exhaust?
Does any one know the rocker arm ratio?
Does the Kleemann kit come with Springs?
I would like to get a cam for N/A motor and am trying to figure out what the motor can handle.
Thanks!

Hi,
Im getting some headers fabricated out of stainless, changing the cats, remove resonator. Im am debating about wither to leave the stock exhaust or get an eisenmann one. They eisenmann ones sound pretty sweet.
Found the MKB site. They include springs. Still would like to know the specs on that stuff.
If the heads flow well has anyone tried to get the motor to rev higher like 7200 or even 7500? No push rods to worry about. Do they use the same rods, and crankshaft in the N/A motor as the S/C motor?
Later,
Robert

Customer headers? Where you located anyway? I got a guy near me who does custom turbo manifolds for a living and we talked but I never pursued it ... hoping Kleemann might have a clearance sale one day... LoL

I live in Portland Oregon. The guy Im going to get the headers made from does custom fabrication for racing. He is going to get the flanges CNC laser cut, and then weld the tubes up, and clearance them, mandrel bends, etc. They will be made out of stainless steel. Hopefully can get them made so they tubes that are the same length. Probably get them ceramic coated afterwards.
I will post pictures of how it turns out.

Hi,
Not quite sure yet but it looks likes right now:
~10 hours of labor at @ 80/hr
$160 for flanges
$200 for materials
It'll be three weeks before I can get them done. I'll let you know how it goes.

MuscleCar on SpikeTV had a segment where the host discovered his Hooker headers wouldn't fit on his Nova project 'cus he made his own motor mounts, so they devoted a good portion of the show showing him using a self build kit measuring, cutting, tacking, welding his own custom headers. ...nice to see!
metal_monster, you know anyone with a C43 who'd like that done too right after yours? ....have the builder make two; I'll buy the other set! The engine compartment is different so the W208/9 headers won't work for a W202 (should go w/o saying, but I said it anyway )
Good luck with it. BTW, for high RPM torque, you can do like speedybenz, disable the two stage manifold and build in velocity stacks:
