Just got an email back form their uk supplier it wont fit the SLK55 AMG, they insisted I check Kleemann.

Anyone knows how much does the Renntech Airbox cost ?

RLx02

~2000 new? I remember someone selling their used one for a c55 for around 1700 or so.

Are you talking about Shrick or Dbilas?

shrick

Try to contact Dbilas and let us know, I heard they have different types of cams that will give a decent HP gain.

Hello. Alroumi, If possible could we see a Dyno sheet with an RPM plot, instead of the wheel speed. If I remember right I was told by Schrick , there was no more M-113 & M-112 off the shelf cams. Somebody would have to pony up for 35 sets . If you do a search, you will read that , the Schrick off the shelf Grind was designed for the 500 engine & after some testing ,it was found that it made no increase in Hp on 5.5 AMG N/A or Komp engines . The hp falls of at 5750 rpms, with stock OEM camsI've buzzed the motor to 6200 many times, on stock AMG Double valve springs & Retainers with no valve float, Currently I've buzzed my motor on the dyno up to 6450 rpm with stock AMG springs & Titanium retainers, and have bounced the tach off of 6600 rpm on the street. Buy the Kleemann cams , they are a Drop in & go . If you think you want a set of cams with a little more aggressive grind ,Do the search in the W-211 section, Lots of good reading. Your car & engine has the good valve springs . Cheers _PTEngineering

Thank you PTE for the comments, I appreciate it. I am eying on the Kleemann camshafts then.

Any upgraded valve springs I can acquire through the aftermarket ?

alroumi

Got a reply back,

Yes, Dbilas do offer a set of cams for this M113 application.

260degree inlet, 268 degree exhaust.

The price of this set is £1660 for an outright buy, brand new billet cams.

So how does it differ to the Kleemann application ?

PTE

Stock springs are very good. 90 psi on the seat & 240 psi at .481 lift. If you need or want Titanium Spring retainers , I stock them , they are priced very competitively close to Ford stuff, No Mercedes luxo tax (LOL) $355.00 for a set of 24. As far as those Dbilas cams, they are very mild so to say. Did they give you a max lobe lift . Stock AMG range from as high as .305 in & . 288 ex . Don't let the low price sway you. Many aftermarket cams, Have press on lobes, They will move, if the motor get hot!! Mercedes tried it once, Then went back to a Grey cast iron cold chilled one piece cam

Did they tell you the expected HP gains?

alroumi

Seems like the Kleemann ones are the best ? Do the Valve springs you have alter the performance when combined with the camshafts ?

I pulled this from Dbilas web site:

Part No.: 12.054.001

Application: Road

Spring :Standard

Duration:260/268

Peak timing: 114

Valve lift:10,8

Lift at TDC : 0,5/1,0

Valve timing IO/IC - EO/EC : 16/64 - 68/20

I have sent an Email to Cory at Kleemann here is what he replied regarding Kleemann Cams:
"Our cams are made for supercharged engine's- I've tested them on SLK55's and C55's which were normally aspirated, and I saw zero HP improvements, so I'd say cams are not worth doing unless you put a supercharger on the car, in which case, they'll pick up another 15-20 HP. "

alroumi

thank you

alroumi

dbilas told me The cam set will see the car gain 25bhp and a further 15lbsft.

I doubt it.

Chazz

Wow. Some threads are just way over my head.

This is one of them.

Havoc

Thanks for sharing!


I think you would need long tube headers with free flowing exhaust and a better flowing intake for the cams to benefit on the 55 N/A.

PTE

Please view the specs in black .They are Schrick off the shelf. They are very close to the dbilas specs. Not as much lift as Kleemann. Take Cory's advice, He is a wealth of Knowledge. I do not have or sell an aftermarket valve spring set. The Stock AMG springs seem to work just fine. Cheers _PTEngineering

What about VRP cams are they any good for 55 N/A?

wawy

I would probably go with the Renntech airbox and pulley (lightened crank and underdrive) before I would do cams...

Havoc

They are the most aggressive cams to date!

The Renntech Airbox yes, but I would also install headers to acheive the full benefits cams have to offer.
