New local dealers are mod maniacs as witnessed by idrive's SL55 Renntech.

Anyway, if they are cool with modding, was thinking of trying to talk them into installing SLR cams in the beast.

Have heard a couple of rumors about this.

Can anyone confirm that you can do this??

..............rumor is that the CAMS Kleemann sells are just the SLR CAMS.

Hey Ted,

Any idea if ECU has to be tweaked for new cams.

Wonder if K2 will work fine??

Ted Baldwin

..............Not certain that the new cams are SLR cams.

...........certain that ECU does not need to be tweaked for new cams.

I've been doing the research on this for a while now...

Kleemann cams are not SLR cams. I asked Cory this question point blank and he told me that the Kleemann cams are a complete custom grind made from billet blanks; that's why they charge $4,400 for the cams.

I am in the process of getting my hands on the cam card which will tell me the specs of the Kleemann cams.

The SLR cams is what I wanted to install in my car. I've asked a few people but I get mixed answers.. Some people say "Yes" the cams will fit and work just fine in our cars.. Some say "No".

The only way to know for sure is to try.. I was quotes $1,400 per cam for the SLR cams. I guess it will be a $3,000 experiment to find out for sure if they will work.

My other choice is to take to the Kleemann "Cam card" and use those specs as a starting point and create a set from billet blanks.. I am waiting on a quote to do just that.

I installed the Kleeman Cams. As I understood things told to me. The Kleemann cams were , of a Similar grind to the SLR grind?? The MB SLR cams are cast type. Kleemann is a Billet shaft with the lopes Brazed in to their approxament place , Then finished custom ground to the Tuners specs. AE. A very expensive way to make cams. But easier to custom fit to special apps. and don't have to build a couple 100 of them.

The SLR mtr # is M155
R/H cam 1550501001
L/H cam 1550500901

I did not have the ECU redone at first. Remember I have a N/A motor.. It really woke the mtr up from 5900 to 6600. Then I had it dynoed . Show no loss of torque , & a 6.5 hp increase in the upper rpm area.
So I called Cory . and sent the ECU back to them for another file to be installed. Well they found me a 10 hp increase over what i already have . and at no additional cost.

Thanks V,

Guess that makes up my mind on that issue. 1400 per cam is nuts when the Klee are proven to work.

Gonna take your advice though Vic and go throttle body first though.

Next question V man is, how hard is the Carbon Fiber air box to install.

I am an average mechanic (worked in a shop for a few years as a punky kid) building a few big block Chevys.

Just wondering if it was something a shadetree could tackle or should I let the stealer??

Look pretty stright forward .... I guess.

vrus

Yeah.. Dont waste your time with cams if you havent done 80mm TB yet.. You will get double the horsepower from the TB than you will from the cams.

As for carbon fiber airbox.. it's the easiest thing to install. Pull off the 2 airtubes, disconnect EGR hose going to Y-pipe intake tube, pop up the 2 airboxes, pull the Y-pipe and whole airbox assembly off the TB.. The whole thing will come out in 1 piece (the 2 air boxes connected to Y-pipe).

I was also told that Kleemann cams are the same as the ones in the SLR. Another kleemann auth dealer told me this. When i was upgrading my cams i wanted to get the SLR but again the guy (forgot his name but's he's an auth K dealer) told me don't bother because it's the same ones. Nonetheless the combination of the cams plus the 80mm TB would be killer!

My above comments was not to discourage the install of cams. My Thought was to encourage you look at what they did for a N/A motor. From what i can gather , a F/I generally responds much better to the same types of mods
AE Headers & exhaust work , N/A 36 Ft Lbs Tqr & 20 Hp increase , F/I motors Approximate 55 ft lbs tqr & 37 hp.
It appears from the out side looking in , most tuners do setups in packages . Not just one step at a time. So the above F/I numbers maybe close but , not completely correct.

IMHO. I thing you sort of hit a stopping point/ THE WALL!!These 3 valve mtrs can only flow so much air . weather it is suck through or blown through.You can try to flow more air through the top of the mtr and try to flow more air out of the exhaust . But I think you are at the point, when the port size & cam Dynamics come into play. No doubt these mtrs make a ton of bottom end torque. I wish there was a less expensive way to achieve the next step. And you guys are right , there is no good anwser for the price of the cams. They are super easy to install. SLR cams are $2380.00 USD for a pair(only 2 pair state side) . Kleemann / Renntech / Brabus. $4100. + USD. Way do they get this price , Because they CAN. I can only hope they go on sale after the new 6.3 comes out.

So these SLR and kleemann cams are the same but the only difference is their price? Same specs? Is that $2380.00 price from an MB dealer? Just trying to clear things up.

Back up 5 posts. for spec build. They ARE SIMILAR. But not exactly the same . The price was Quoted from my friendly local MB dealer. Lets wait and see with what Vitor comes up in the way of cam Cards

JamE55

Got it. Thank PTE.

vrus

Confirmed!

1) SLR cams will NOT fit in our cars.
2) Kleeman cams are ground to same specs as SLR cams but made from billet blanks.

Conclusion: Need to find a way to get some billet blanks and get them setup per SLR specs.
