So I finally got around to swapping my NA (stock) C55 cams for 55k cams. I hit the dyno and.................. gained ZERO HP. Infact it didn't even move the power around or change the ARF. It did drop the boost my 1/2lb. whatever though.

Last night I did a cat delete and swapped in my "test pipes" Hit the dyno today and gained......... ZERO HP. However, strangely enough, it knocked my head exploding drone down quite a bit.. so I will take that as a plus. I also think my car sounds more like it did with my last exhaust system, and I liked that sound better.

As of now I'm stuck with 480whp. I think my currant intake design is bottle necking my power. I'm going to have to do an bigger throttle body and totally redesign the way my car sucks air. So this goal for 500whp eludes me another day.

jturkel

that sucks

did you resolve some of those "problems" you were having with the car mike? namely the belt slip, idler bearing, and exhaust problem you got yourself into? lol

you gonna check with your manufacturer about a custom TB? if so....i may join you as well

and yes, i think your intake it a bottleneck. it is not getting enough air flow. it isnt even near the radiator support/intake inlet.....it needs greater exposure.........aka.........take out one of those inner headlights....one on each side (its not like you use those ones much anyway).....and dual ram intake with maximum air exposure....ftw! lol (ok ok, i know how much you hate that idea)

hooleyboy

Sure you can join me. The belt slip was some oil on the belt, After some inspection, It looked good to me. The idler pulley was going to get replaced today. But My buddies at the dealer game me the wrong part my mistake.. Even after I checked it out at the dealer. I want totally paying attention. You know there are some smokin hot chicks who work at Schumacher MB. It seems today they were all by the parts Dpt.

And NO! I'm not cutting up my headlights! I will just find another way to get more air. My exhaust is killer right now. I'm going to be trying like 3 different styles of new mufflers out, to see what one I like the best.

I vote you find a cost effective intake system that we can all steal from you once created. hahaha

Sucks that neither would pick up any gains for you =/

MBH motorsports

I think some beer and a bar stool will help me come up with a cool idea. If I was still NA I would build a crazy intake. I've got to but some real thought into this next move.

Cant wait until after the holidays, I'm thinking SLR bottom end. Saving my pennies now.

SoCalC55

Well no plans to be in Peoria(GFs family) anytome soon, but if I do make it out there ill help buy some of that "thinking beer"!

MRAMG1

Well it sucks to hear you went through all of that hassle for no gain my friend.

I guess the boys at AMG did a GOOD job on the cams after all. I am REALLY surprised that there was no gain here
After all, NA cams usually have A LOT more overlap to increase scavenging. And then you LOST boost with the SC cams which should have had less overlap and add MORE boost
Doesn't make much sense but I TRULY believe in you my friend.

Good luck with the other mods and keep us posted please

maybe just try boring it from a 5.4L to a 5.6L. i'm sure that'll be cheaper then saving for a slr block.

How different are the cam profiles?

How many mm is the stock MAF?

For throttle body modifications, you may want to try Accufab (http://www.accufabracing.com). If anyone can mod your stock TB or create you a new one, it'd be them.

Dang! Thats unfortunate to hear hooley. How do you manage to lose half a pound of boost but still make the same power? Isnt that a good thing? Keep us posted on that intake design

AMGSC

Mike, I've got an extra new 82MM TB I can sell you if your interested...You just need to fabricate an adapter plate to the SC and maybe bore out the housing unit. The E55 Y-pipe will work just fine with the 82 as well. Paypal me $300 and it's yours.

hooley if you want to get rid of your n/a 55 cams i know a guy looking for some

AMGSC

Or he can just buy my block which is ready to be bored out to 6.1L for $500.
I am thinking about doing that but I think Hooley has more technical resources at his disposal.

I would have to send the block to the shop that does it for Brabus. With iron sleeves, the walls should be strong enough to install some massive Garrett Twin Turbos.

AMGSC

Mine are up for sale now.

lantanatx has already spoke to hooley and he is buying his. he did a m/b v8 swap into his chrysler crossfire!

I have a new in the box set of SLR cams for sale.
Sold my E55 for a CLK63BS and never got to use them.

Mike, I believe what you are experiencing is similar to what Kleemann (factory) has experienced with the C55 SC. There are no (if any) gains with the cams they offer for the conversion to SC. Thats why my car does NOT have them since the cost of parts and install did not justify the alleged HP gains.

hooleyboy

Not to mention the installer has to have the MBZ cam tool to install them. Its a messy job too.

F1Bobby

Damn! All that for Zero gain. That bites. On the brighter side of things I wish I was stuck with 480 whp in my sled.

Is honesty like this that we appreciate here thanks
