dyno numbers
I finally did a dyno on my 99 430. I have the AMG intake and the resonator removed. I also have K&N filters. Anyway, here is my graph. Does it look right....look bad.....any comments?????

Well they didn't give me the sheet on it. I believe they might have. I swear while I was standing there I saw a number that was around 15.8 to 16.2. If I'm right, what does that tell you?

That means you had a 16 to 1 air fuel ratio, not good for WOT ( wide open throttle). For WOT it should be around 12.8 to 1 or somewhere close to that.
It seems you are putting 215 HP that seems rather low for a V8. What type of dyno did you get it done at? ( dynojet, mustang?)
Back when I was into racing my CRX, I did many dyno pulls. 1.8 liters 4 cylinders DOHC VTEC put down 201.8 HP and 132 lb/ft of torque (12.5 to 1 a/f ratio) naturally aspirated. That little car (1800lb) was a monster.

............maybe I'm missing something. The spec of the CLK 430 is 275 crank HP. He made 215RWHP. How is this incorrect?

So, my theory is, the 99 CLK430's just can't be dynoed.

I have the AMG intake. I believe stock it should get about 215. With the intake it should get at least a little bit more.
...........You are another victim of propaganda. Unfortunately, without a before and after dyno showing RWHP gain or loss, you have simply given free money to the vendor you bought the intakes from. What you believe the the baseline dyno should be is unfortunately not useful without actually obtaining the dyno. The truth is that most of these mods do not increase HP whatsoever. Before you buy any performance mods, ask for a dynograph showing HP gain on a car that was physically dyonoed before and then physically dynoed on the same machine after the mods are installed. Otherwise, keep your money in your pocket. Your car makes 215RWHP which may be a bit more or less depending on environmental conditions. All you can do is to use your current dyno as a baseline for future mods.

Ted,
He bought the intake and filters from me. My car dyno'd 216 HP/232 tq stock, and 234 hp/245 tq with no other modifications.
I produced dyno graphs to back this up. Others using the CLK55 box have obtained similar results.
My horsepower and torque curves were noticeably smoother, and I never hit anywhere near 16:1 on my a/f.
JT, are you running stock software? I've yet to see good dyno results on chips. The last one I saw was an S55 which gained 8 hp and 16 ft/lbs of torque when it was flashed back to stock software.
You have a pretty big dip in power early on and without seeing your a/f it's tough to tell what it could be (possibly misfiring?)

haters crazy
99 CLK430's cant be dynoed properly. End of story. I actually gained 10whp and 5tq with software on a dynojet dyno (3 runs before and 3 runs after). I dont think its accurate. You cant floor the car in third without it downshifting right so how are you supposed to get an accurate reading?

As far as running the stock software.....I really don't know. I "supposedly" have now had my ecu done twice by a company but I don't think it worked either time as they claim it removes the top speed limiter and mine is definitely not gone. So I could still be running stock software or I could be running some sort of variant.
The guy dyno'ing it took it up to about 55 mph or so and opened it up. My car didn't downshift on the first two runs. On the last run it did though as he started just a shade earlier.

What's the big deal about the dyno anyway, I always thought it was about how the car felt when you drove it. Who you could and could not take down when you line up at the stoplight. When your on the street no one is going to ask to see your dyno sheet. One of two things will happen you smoke them or they smoke you.

As far as dyno is concerned, I put my new 02 CLK 430 on the dynojet, removing the airbox, all stock with only Brabus springs and I got:
245 Rwhp and
251 Torque.
I have the photos of the dyno charts at home, I'll post again if anyone wants to see them.

JT, if you've had Speedtuning do work on your car, I suggest that you have them reflash your computer back to stock. You should get your HP back.
Ghostrider, the S55 that lost HP was using Powerchips software. Not saying that their stuff might not work for you, but unless the chip was made for that particular car while it was being run on a dyno, I've yet to see good gains from "mail order tuning."

Funny thing is, since I bought the car back in February or whatever it was, not one person has lined up or raced me other than Str8ridin....and that's just because we wanted to see how much of a difference there was in our cars. Not that I mind, but there are tons of Stangs and Camaro's and jap racers in this town and plenty of college kids and not one has tried to get a piece of me.

Oh, plus I talked to them about just putting it back and taking their software off since it's isn't doing crap for me anyway. They said no problem but they won't give me my money back. I think all of the stuff I'm going through with them is total crap and they don't back their sh*t up at all with any guarantees. I know for a fact I'll never see one penny of a refund from them and so far it's just money flushed down the toilet.

I have heard that these cars a bad to dyno because of the transmission and how it work with the dyno. I don't know how true that is, but I can tell you that since I put on my exhaust and pulleys I can really feel a difference, but it is playing havoc with my transmission. In my last car mail order tuning did alright by me.

CLK 430
Add me to the list ...
I added a CAI - full 3" alum / HTS from the manifold all the way to the 6" K&N vented through front fascia. Only pulled 228 HP on a Dynojet. 22% drivetrain loss (mentioned above) sounds very generous; and even that would put me right around stock HP. I know the CAI had some effect because I picked up a full MPH in the 1/4 in 90 degree heat using it. I dont have before / after dyno runs but I do have timeslips including before/after 1/4 times.
Guesses: no torque converter lock up? No "dyno mode" for the 1999 like they have on the '03 and up?
