That is on paper. US guys are fitting the Euro headers onto their cars & getting 10-12hp on the wheels bolt-on. And it helps with torque throughout the rev-range. US M3 headers have the catts integrated.

Here are the euro headers with a bit of a marketing speech:

http://www.turnermotorsport.com/html...DUCT_ID=043901



BMW changed two obvious things on the Euro E46M3 when they brought the car to the USA - They added the yellow reflectors to the front bumper and they changed the location of the catalyst in relation to the motor. For the USA BMW moved the catalyst very close to the head, in the exhaust manifold. It was put there to heat it up faster for better cold start emissions. The detriment of this change is that it causes a loss of almost 11 HP at 7,700 rpm and 17 lb/ft torque at around 4000 rpm. Well, we have a way of getting that HP back. Installing the Euro header and catalyst is a direct bolt on way to increase horsepower and torque. These factory original parts bolt on to the USA/Canada car and are supplied with all the necessary gaskets - even copper manifold nuts ! (You will need to lengthen the wires on your existing oxygen sensors) A Specially Tuned Software (Shark Injector) for this kit is available to maximize drivability and power - we highly suggest this. What you will notice is a "night and day" difference in the power band - the motor is smoother, the car accelerates faster and some of the "rasp" of the stock exhaust is gone-although there is only a 11hp gain by installing this system the 17lb/ft of torque increase at low rpm makes a huge difference. This is a GREAT first modification for your M3; it uses factory designed parts and does not cause reliability issues. Please note that this modification is sold for off road / race use only even though it may still pass emissions. Also available for the S54 M Coupe and Roadster!

 

SLK and driving skills in the same sentence?

Seriously though, I drove M&M's M3 too with the same results. So that must make him a **** driver too. The M3 is MUCH, I repeat, MUCH harder to get to go fast than the SLK is. SLK is easy. ESP off, powerbrake, let go of brake and floor the gas. Man that was hard. I was mentally drained afterwards.

Tell you guys what. We will make another video in the near future.

M&M's M3, my SLK, another STOCK SLK, a stock M3 and maybe even an RS4 and a C55 too. Until then

 

may want to get a stock M3 while ur at that.

 

Let me quote myself:

 

Yeah we know how tuneable these M3's are. M division took 2 years to make the CSL, changed a whole lot of hardware, went to Alpha N programming with the map sensor & got 15hp over a stock Euro spec.

 

OK quick question.

How much could you get out of an M3 if you were to supercharge/turbocharge it?

Surely you could get a lot out of it?

 

OK I learnt something new today. Reading the MB world forums & wondering why US M3's are weak, especially after 3rd gear, when racing 55's. Today I foound out.

Evosport sell a header which is basically the Euro version which we have stock on our cars. Then they tuned for is (as the US M3 has different tuning). Here's the graphs of a US spec M3 with the Euro headers & tuning for it:

 

Which is why, of course, you updated your car with all of those modifications, yes? Because they don't work, eh?

But you've always been a liar. Here is a partial list of the lies in which I personally have busted you:

M&M gets busted lying about Car & Driver test car "not having launch control"
when, as I showed via a link to his posts, he had participated in discussion on M5 board, twice, about the car having launch control:

M&M continued to lie, stating that even though I'd found a post of his in the South Africa Audi club where he bragged about how much drag radials had helped his car's launch at about the same date from which he'd posted his timeslip, well, by golly, he actually got better times without them. But then, I found the following, where he'd actually admitted (again at the South Africa Audi forum) that he *HAD* run his best time with semi-slicks (drag radials):

Improviz, you a virgin?

Do you have keyboard binds for those links?

M&M, interesting that you posted here that your fastest time was not done with drag radials, and yet you posted in the South Africa Audi forum that it was:
https://mbworld.org/forums/showpost....&postcount=112

Gee...you wouldn't be lying again, now would you?

 

Chimp, breaking news. Your list is impressive but you can scratch the "lying about drag tyres" 'cos I posted about that BEFORE you posted saying "Guess what, M&M has drag tyres"

 

No. 13.54 at 5500 ft elevation with Dr's. I never mentioned that time again. 13.71 with DR's & without DR's. We've been through this but let's do it again shall we? Whenever you ready.

 

Man, I can feel Impro's PC overload from here.

 

Yes, Soulblade posted in the SLK55 Forum that a new Z4 was going to be faster than an SLK55 based on the fact his SLK55 got pulled by a STOCK M3 (which he later back peddled, in this thread in fact), that he only confirmed with the M3 owner that no "engine mods" were done. Well, a better flowing air filter, a rear gear diff change, and an exhaust just don't contribute to being NON stock I guess. The M3 was not stock. If it were, it would get PULLED by the SLK55. Period.

Another lie to add to the pile. People can see what you wrote, and when, by reading these two posts.

YEah, you probably right. But I still don't see the part where anyone said it was stock?

 

Hey, some oke claimed the SLK would rape a Z4M. Z4 has M3 motor and weighs less so it's faster. I never lied about anything? WTF?

LIKE I SAID. I E-MAILED M&M AND TOLD HIM TO COME MAKE SURE I WAS FACTUALLY CORRECT. HE CORRECTED ME ON THE ****ING DIFF. WHAT ABOUT THIS DOESN'T MAKE SENSE. Ahem. Moving on.

1hp air filter and 0hp exchaust BACKBOX won't make a difference. The diff will.

 

It's quite odd that soulblade defends m&m so vehemently when everyone here knows that he is an accomplished liar.

Here are some more to add to the pile. User zumbalak, who has also posted here, nailed M&M on the audiworld S4 forum posting phony pics of "his" M3 at the track--twice!

M&M gets busted by user zumbalak in Audiworld's S4 forum. First, he posts following photo of him driving his M3 at the track:

zumbalak then analyzed some other photos M&M posted of "him" in "his" silver M3, which had by then morphed into a smurf blue model (look at the a-piller; exterior paint is clearly smurf blue!)

Err, no stock CSL is going to pull a stock SLK55. In fact, seems you want an AMG SLK32 because you miss forced induction so much. http://www.m5board.com/vbulletin/sho...838#post777838

HINT: An SLK32 is slower than an SLK55.

-Matt

 

Haha. That was a joke I know Pitzi, he would

a) never drive an auto; and
b) never drive a hairdressers car

Rofl. He's looking at importing a C6 ZO6 from the States as we speak. Which is NOTHING like an SLK 32.

Oh, yeah, and have you ever seen a CSL in action? It's fast and **** ese.

*Edit*

CSL vs SLK 55

Hey here's that video of me vs Pitzi. Watch me launch the **** out of the SLK. CSL wasn't using launch control. Both cars running 1/2 a tank of Shell V-Power 95, the best pump gas we have. Both cars have 2 people on board. THE CSL RUNS THE SLK DOWN FROM BEHIND.

The SLK was launched like a demon and I held my foot FLAT all the way. ESP off and the gearbox in Sport mode. Even Improwimp admitted it to be accurate. So what now Einstein? TORQUE DOESN'T WIN RACES, HORSEPOWER DOES. No one races from ****ing 2000rpm.

Both cars have 265kw, but the CSL is lighter. The CSL also holds the power better to redline + has a more efficient drivetrain. Which is EXACTLY what the video shows. /end class.

 

Holy **** Improviz. Do you print those links out and make love to them?

 

Imp, here's the think about saying some-one's lying. You need to show then saying something then prove otherwise. WHere did I say that silver car on the circuit was mine? You know we have a great bunch of pals & we often drive each other's cars. Read my post again. I said, "here I am on the track". I didn't say it was my car. What does it matter anyway.

The same applies to you other bull**** claims that I lied. There is no proof at all. Get a life man.

 

Hmm, you must be very "frustrated", given the amount of time you spend pondering about my sex life. Why don't you and your sweetie-face Sherwin go get a few new issues of Roundel and do some circle-jerks to the nice BMW photos, eh?

Or, better still: post a photo of your right hand so we can see ol' Sherwin's girlfriend.

 

Wow, so you won't admit to having lied in the past??? Who woulda thunk it....gee, I really was expecting you to come clean there, Sherwin.

People can certainly click on the links for themselves and decide whether or not you are honest, as I was always very meticulous when I created those posts and was sure to include your original claims and/or posts. It is quite clear to anyone who reads them that you were lying, full stop.
