speed43

I have just spoken to a member here that had the C43 with the upgrade engine.
He told me that with the bigger engine he was able to beat many fast cars.
I totally believe him for he has no reason to lie. But all I have read in threads is how much better the c43 runs with the bigger engine. I have not read how many cars people have beat with this setup.

So I thought maybe I missed this thread!
I understand that most won't be racing but some will.
For those of you that do or have, can you share your experience when you first raced a car that you would have never raced with the stock c43 engine?

I look forward to next summer finishing my body mods on my c43.
Than after I hope to be able to do the 5.4 swap.

I will say that the 5.4 swap (for me anyway) has been a road chock full of information causing disappointment, confusion and chaos. My 5.4 lays in pieces in my storage shed waiting for me to make serious decisions.

After going through and knowing everything I know today, I'd probably forego the 5.4 swap, just look around for a used supercharger to slap on the 4.3 and call it a day. In fact, I think there is one on ebay right now.

Tell him you need the works for your c43 and I'm sure he'll deep discount it with the sale of everything else. Just realized seller is kleeman_usa so they've got everything you need.

speed43

From what I can tell is that you weren't able to install the 5.4 on your c43? Your signature though says you have done the swap so it's a little confusing..

I'm not interested at all in a super charger on any engine.
I like finding hidden power, small things that help make a difference to other components of the engine. No not trying to promote my air boxes, that ship has sailed, but for anyone interested I do have two last ones to sell,lol.

But getting back on topic, I'm very surprised to read your experience and appreciate the info.

Good write-up with Nice Thread Geo..,

completely agree with every word,

don't know the reason why people with C43/55, not sharing about how they surprises the arrogant fancy boys with their new "FAST" machines, of course including ME..!!

if anyone here, had or have a good RACE story with cocky dolls, just don't hesitate to chime in..

,,ZAYED,,

Was slightly pulling on a M6 once and keeping up solid with a s55k on the freeway.

speed43

Thanks, and yeah I'm surprised that there's such a silence.
Be nice if anyone has video clips they could share.

Above 80mph its faster than a new Porsche Targa 4... tried 3 pulls at 80mph...

My commute to work is 40 miles down long motor ways. I've also crushed lesser cars like ricers, g35/g37, non-M bmw, dodge charger rt, genesis coupe, etc. But none of those are impressive and my stock 43 could've smoked them too. It's important to note the 55 swap still doesn't make the car a crazy fast performer off the line due to the gearing. But at 60mph and above its shocking how hard it pulls now.

speed43

I'm glad you mentioned the dodge charger, there are so MANY of them here in Chicago. You think the dealer had a special buy one get the one free. To bad the 55 motor still slow of the line. My c43 of the line just spins the tires than after it goes. Truthfully, it wouldn't spin tires like this before. But with the mesh screen removed from the maf and the maf housing ported and the elbow it does it all the time.

I hope next summer or one day I can do this swap. In the meantime I'm going to be finding power to add/mod so I can swap that to the 55 engine.

All I need is that port & elbow. Just moved to California so it is refreshing to feel the 43 fast again. Elevation in Colorado really stifles NA motors. Love the airbox & so does the car; cool weather plus these mods seem to frequently make that flashy yellow thing pop up on my dash Now all I need is a 55...& a blower..& an lsd.. & built trans.. & coilovers..etc etc

cm60k

+1,

Drivetrain (gearbox/diff.) are the only things that kills the quick reaction we need & looking for..!!,

but anyhow;

Anyone still using "4.2l", go with "5.4l",,

believe me; BIG smile will engraved on the boring FACES..

,,ZAYED,,

speed43

Nice move Hayden. I have one elbow and maf left. These two things will make that flashy yellow thing flash more. Not to mention the throttle response when you punch it! $50.00

Sulaco

335 coupe tried to pull on me. big, empty open highway. he was riding my *** a foot from my bumper. I hear him floor it, see him swerve into the slow lane to pass me, so I floor it. I instantly matched his momentum, so he swerved back in behind me and stayed INCHES from my rear bumper up until about 110mph where he tried to switch lanes and go around me, but the air was too much for him and it pushed him back and he learned his lesson. I was pretty sure if I had let off the throttle sooner the dumbass would've hit me in the rear.

was a really bad idea and I should have just ignored him. I still have my rear-end swaying back and forth a bit when I'm on the throttle...

anyway, I cross 300,000 miles in 40 more miles

edit: I don't think his car was tuned or anything, it looked stock and was gold colored. pretty sure a tuned 335 would destroy me.

Excellent..

I don't race many people, but I drive a variety of Mercedes every day, all the AMG's etc. The 5.4 w202 is no giant killer but it'll run with alot of cars. Impromptu races on the streets, the huge and wide torque band combined with a pretty light car will walk away from alot. The longer the race, the longer pure HP will edge out.
I raced a co-worker many times on the freeway, he had a new 370z NISMO and thought it was special. We raced many times, starting speeds anywhere from 20mph to 60mph, going to 100+. I absolutely destroyed him every time. The last rounds I'd even give him the jump just to make sure. The torque hit instantly put a car on him and I'd keep pulling and be several cars ahead every time. That car is supposed to run lower 13's in the quarter mile, all I know is it was not even close. I do have headers, no cats, renntech box, later cams, motor is healthy but nothing crazy. A stock w211e55 will easily walk away from a c55 at higher speeds but short runs it's a race.

PJmak

Benzslo is the gain from these cams you are using worth the hassle?(also are these grom a 05 + m113?)

benzslo

I think being worth the hassle is a very subjective thing. The differences were minor but were there, kind of what I was going for, each thing is small piece of the puzzle. My motor came from a w210. Cams out of a 209 CLK. Just look at the shift points of those two different vehicles, and the power/tq differences. I felt the 55 would lay down a little in the last 500 rpm or so before shifting, the cams made a difference there. Down low brute torque may have softened slightly but still has an abundance down there anyway. I'd do it again, but it might be a little more involved than some folks are comfortable with. Or if you don't have high Flow exhaust, results may be different also. You're not going to see drastic changes, I think anyone claiming that from this kind of stuff is full of it, just have to build towards something.

DRBC43AMG

I have to agree with what you say, but I guess some work on the cylinder heads first would be a good starting point. Even if the link and photos in the link describe M113K heads, I don't think there would be a difference between K and NA.

benzslo

There is always more power in cylinder heads, that is for sure and if I was going all in on this thing, they would have got worked. For me I wasn't trying to go that far. I like it being everything is factory. You know it all works for one. This car for me is just a nice driver and I'm just trying to make it how I think it should have came from the factory, if I wanted to get crazy I'd pick a whole different car, been there, have other hobbies now I like more than checkbook racing . A nice head job on one of these goes for more than what I have into my whole motor I'm sure. And alot of times it's a trade off, you're likely losing something, then still stuck with the same shift points unless you have a 2000 model year. After selling my old cams I came out even.

DRBC43AMG

Yeah, it depends how deep are your pockets and the thickness of the wallet...

Sulaco

A 370z? Even the Nismo version is quite disappointing. It's almost the exact same weight as the C43/55 but the C55 has 42% more torque. There is no way on earth that car was ever going to stand a chance. Maybe red-light to red-light, where you're at a dead-stop and the next red-light is 100 yards away. But anything beyond that first 300 feet the 55 will eat the Nismo alive.

My commute has people pushing me to race quite often now. I had to start making my wife drive so that I wouldn't be in control, because I'm an idiot and have trouble resisting them. But did outrun an M56S and riced up Cobalt SS (kinda embarrassing to say I even bothered, but he was riced up and kept wanting to try over and over again, never stood a chance).

Would have had an interesting race against a new S4. He at least had exhaust done because I could hear it even with my windows up. He started in front of me and I was pulling just as hard for 3 seconds until my wife started yelling at me... Would've been an interesting comparison!

mickey13

you're very lucky to have someone to balance you out. my current belle is from the ukraine and she loves to go fast so we get into trouble a lot. lol

benzslo

Just stating my experience like I said that car is supposed to run low 13's. And not much out there with street tires will beat it off the line, someone was saying there's is slow off the line, not sure what's up with that as mine rips, that's where the biggest 55 gains were felt is that 0-60

Sulaco

speaking of, I have been very curious about what the w202 C55 can do 0 to 60 now. There's never been anything published. But if this combo gets the w210 to 60 in 4.9, what's it like on the w202? I imagine it's not quite that fast due to the restrictive exhaust and gearing.

Can one of us get the proper instrument to test it?

benzslo

I'd imagine a well running w202 is just as quick as the 210 or the CLK if not more so. Lighter and geared lower.
