Hi everyone I've seen several people on the forum say they're running SLR cams. I wanted to know what would be involved besides purchasing the cams and tuning to physically make them work? Thanks for the help.

Worth the wait

No offense....but there are literally dozens of threads about this. Chiromickey (and a few others) pioneered it years ago.

Search and all will be answered.

I've searched and read the threads I could find, but I hadn't seen one that spells out what else needs to be done?

PM Jakpro (Jim) he has run SLR cams and he can give you more than a little insight.

Got your pm and will reply later after fam time today. AMG freaked when dozens of SLR cams started flying off the shelves and shut down sales HARD. From what I hear, you have to have an SLR vin to get them and AMG does investigate each.

Imagine there coveted supercar (or so they thought) had the worst cams ever made. They were going bad by the dozens. LOL, I just can't get enough of that man. My buddy Ken and I started it all.

Anyway, Kleemann cams pretty much are the SLR cams so perhaps look around for some Kleemann cams or give Corey a call.

SLR cams do pop up so have cash ready and jump when they come up. Klee cams are lots of cash so heads up. Maybe they have dropped prices....check with them.

I can get a set of SLR's for 2200, I'm mostly interested in putting in the most aggressive cams possible. I'm shooting for 10's later this year. Also I know I need a Vin from a SLR

Hammer Down

You don't need cams to run tens, save yourself the headache and focus on something else. Ask around most guys that run cams end up taking them out.

PACougar

Thanks for the info, but to get the best VE, I really am going for the cams. If I can get another tenth or so, it's worth the headache any day...

Thanks

Here's your recipe for 10s.

1) Custom EC tune, Renn has been doing some amazing work lately well.
2) LONNNNGG tube headers. No shortys. Res removal makes no diff IMO hp wise.
3) Roughly 180mm pulley. I can't mention his name or he freaks on me but the current 10 sec champion ran slower with larger pulley when he upped it to 185
4)LSD
5) 82mm tb with VRP or comparable intake tubes. NOT STOCKERS.
6) Separate your inter cooler and radiator line and install the largest heat exchanger you can fit in that sucker. Johnson 30 pump or similar pushing back to the truck with 5gal min trunk cooler installed. Have a Johnson 30 or similar pushing front and she will be nice a cool on high r runs.
7) stickiest tire combo you are safe to live with. Some of these animals are running bias tube slicks in the rear with radials front. INSANE but no problems knock on wood so mod on you animals.

Cams will give you 15hp up top so it will help at the end of the 1/4. If you snag SLRs...KNOW THIS they need a spacer put in the front over the cam sensor so she doesn't make contact with the gears. Other than that...works friggin awesome. I may have the spacer still here if you need it. Without, get ready to scrape metal all out of the engine....for real.

PACougar

Jakpro1 perfect write up. I already have most of those parts shipping to me, I'm still deciding on pulley but I'll definitely factor in what you've said. The information about the cam install is exactly what I'm looking for. If you do still have a spacer, I'd love to pick it up off of you just PM a price. Thanks again.

AMGfan

Or you could have gone to PTE cams . Jim great write above...on the wheel tire setup...you can go with CCW 16" drag setup with Mickey Thompsons which I happen to have in my storage unit sitting in some nice tire satchels.

Cams are a waster of time
C55asleep? installed SLR cams and after all that hassle
He saw very little power gains at the dyno
All he had to show for it was a car with a lumpy idle.
He quickly sold his C55 shortly thereafter.

chiromikey

you're confusing slr cams with vrp/pte cams...i don't believe there has been anyone that's had headaches from running slr cams.

slr cams do not change idle characteristics. again, people may be confusing slr cams with vrp/pte cams.

chiromikey

make sure you search for the full instructions on the slr cam install, i'm sure i posted it around here a few years ago. there are a few things that need to be done with the slr cams to get them to install perfectly.

AMGPilot

Sounds like the VRP cams NOT the SLR cams.

Properly installed SLR cams make power and do not affect the idle. I've had them in my car for over 70K miles and don't regret the choice

moosejaw

Well you cant argue with 70K miles.
Nope these were definitely SLR cams. bought from a forum member, PTE Engineering (Patrick) a while back.

https://mbworld.org/forums/c32-amg-c...4828-cams.html

and he traded in the car with them installed at a GM Dealership
https://mbworld.org/forums/3235820-post20.html
https://mbworld.org/forums/3235820-post21.html

He only had them on like a month and wasnt happy with the dyno numbers over his last run (same place, same conditions) which is why he never posted results.
He traded in the car shortly thereafter. OP you can PM him for more information.

chiromikey

slr cams do not cause idle issues in 55k motors so they were either not slr cams or installed improperly. if your friend installed them in a non kompressor motor maybe that was the problem.

either way it seems strange that he bought slr cams and not pte cams from pte...

moosejaw

very much so....
I was always led to believe that SLR cams didnt produce any gains. Patrick is local to both of us, and i see him once in a while. They werent PTE cams

Cams are cool, but I think often people look at the max power gains from cams and thats not really where they shine your mid curve power is where the cams make the difference from 2krpm on up the power band is higher.

This is quite odd as I grew up using wilder cams to shift the power band up the rev range and allowing the motor to rev more freely. On F/I it is different though - I am lead to believe. The cam lobe profiles are visibly different although not immediately obvious between the klee and the stock cams....

Its interesting comparing a cam car and a non cammed car... its subtle but the revs definitely climb faster and the engine feels less aneamic at high rpm into redline.

chiromikey

iirc, i gained around 15hp from 3k rpms to redline and the car always idled like stock.

PTE

SLR or SLR copies & Kleemann cams installed in a N/A
is good for about 11 - 13 Hp. C55Asleep knew this when he was sold those cams.

Back then, I ran & Tested lots of cams. to develop the cams for VRP. Vrp Cams have the most lift & Duration A stock cylinder head & with the valve to piston clearance you could safely have. Many Consumers could not deal with the idle that came with a motor that used a Manifold absolute pressure sensor, ( Speed density system) These VRP/PTE cams offer no lose of bottom end torque Or Hp. and very good gains in the upper rpm Band. They adapt very well with a Mass air flow sensor system of a 55 AMG N/A motor


Hell some Guys hated these cams . But more often than not is was a mechanical issue. Air leaks & Just flat installed 1 tooth off. Heck there is over 45 sets out there , most purchasers can dealer with the idle , if everything is perfect. they will idle like they are suppose to . Close to a STV Rousch Mustang. Please check the Blower thread in the CLK 55 section. Even a good tech makes mistakes . and when the car went to Cory at Kleemann to be straightened out , he found there was a code for cam timing stored !! and the Installers tech did not catch it?? Great Props to Cory. I often recommend Kleemann cams because there idle Quality is smoother than PTE / VRP Cams and offer a good gain in horsepower on a F/I Motor
Cheers _PTEngineering

PACougar

Patrick, I have no problem with a rough idle, I just want the most output possible. That's why I want your cams

AMGfan

I loved the idle of the E55 with the PTE cams...once it settled down everyone knew that it had bad intentions. I think you will be happy with them...
