I remember you saying that before, but remember R Stevens did it without putting it in dyno mode and only got 171.5 hp. That's why I asked the question about dyno mode.

I don't know if he has or not before on this site. I pm'ed him to see if he has.

Only way that would work without the ESP going crazy is if all four tires were on rollers (i.e. 4wd dyno). Otherwise, ESP will continue locking the wheels up.

I don't have 2.3l, 2003 is a 1.8 m271 as well.

It means that they no longer carry the parts at Kleemann USA for one reason or another. They can however, still get pretty much any part from Denmark. They stopped carrying the pully kit and headers because there wasn't much of a demand here in the states for them. In Denmark/Europe however the demand is still quite high for them so they are still being produced.

So I called Kleemann to see if I misunderstood anything they told me before, and the answer is "no". Rick at Kleemann told me again to expect gains of 45hp-50hp with both boost kit and headers installed. So we'll just have to wait and see for my install and dyno runs.

You're gonna have stock dynos also, right? Only way to get a good guage on how much power you really gain.

Not sure, you can check the classified section; you can special order the kit through Kleemann USA, but it will cost because it's comming from Denmark. Don't know anything about Nos..... sorry.

I think on the other M271 based versions of the W203, they engine is detuned, but it's still the same engine, just set up to put out less power, thru software. So it's very easy for a tuner like Kleeman to
up the power with a chip. I believe the C180 gets the most gains from little more than updated software from Kleeman.

Certainly the best deal can be had in Europe by getting the C180 and chipping it. I have to seriously doubt that anything is actually different mechanically between the various versions. Just a way to make more money selling the same product to different market segments.

Now Drexx you said you have yet to see an m271 break the 200 barrier, but pugguy2001 says he has.

Another example is what's on Kleemann's site, they claim that a C200 with the same m271 went from 163 to 210(don't know if was at wheels). Of course that's what Kleemann claims so who knows exactly. Truth be told, all of this means nothing until I get the install done and my own dyno results.

Here are my dynos guys. They were posted on another MB forum a while ago.
I told them the wrong redline so the torque average # is way off on the text dyno it is actually 205 and not 653.8!

Wow, that is impressive; 204.9 on a Mustang dyno, which we know is 8-10% less than dynojet. I can't wait!!!!.....

I see this:

Max Power 183.9 @ 5983 RPM / 122.9 MPH
with WCF 204.9
The WCF is weather correction factor, which some people have debated would be equivalent to what a dynojet would put out. I'm not sure exactly how that number is determined, but these are pretty good numbers!

Any stock numbers to compare to? There's no telling how much increase there actually was without those.

I agree on the weather correction factor(don't know how # is calculated), but not sure if WCF is dynojet equivalent; I've seen some dynoes where WCF is actually lower than max power.

Edit: After research, I found that max power is the uncorrected value and WCF is the corrected value based on ideal weather conditions(thanks Drex for the link).

If I were to give a good guestimate, I'd say that the actual power number is somewhere in between the 183 vs. 204 (approx. 193/194). And even then, I'd venture to say that the weather correction factor would not determine how the car is on the street. 183 sounds like the most realistic numbers considering the other Kleemanized dynos I've seen (w/ boost kit and headers). Thing is, my car dyno'd at 171 at the wheels on the dynapak (stock w/ just k&n filter), so if we were to say that there is a 5-7hp difference between the two different dynos, that's a gain of 17hp (w/ the boost kit and headers - just looking at the 183 w/o wcf). That sounds about right.

Either way, it's been proven that there are gains from the mods. How much has always been a question. Looking forward to seeing your outcome hawaiian.

I'm looking forward to my results as well. One question though,..... isn't a difference around 10% between the two dynos more than 5-7hp you used in your "guesstimation?" Isn't it more like ~18-20hp difference? If so it would be more like ~28hp gain uncorrected and ~49hp gain corrected going off your #'s right? Ok so that was 3 questions. But like you said, how much gain is always in question because of the lack of before dynos to go with after. It's hard to base a gain off of someone else's stock dyno because there's so many variables that can affect a dyno and not to mention every car is different.

Unfortantly I never had a pre mod dyno. I kinda wish I had one just to see my actual gains. Between the Kleemann mods and the sprintbooster my car is a totally differnt machine. The more I drive it the more I realize holy sh!* I cant getover how fast it is. Third gear (in steptronic, i have an auto) is my best gear. It feels like the car is pulling the outside into the car. Its sometimes gets scary because if I dont judge things right I would just get sucked into what ever lies in front of me! Dont get me wrong all my other gears pull just as hard but it iseems like I like to drive in third gear all the time. Thats from 55-85 mph.
Hey Drex does the weather correction factor start at around 60 miles per hour, when driving? It seems like the faster I go the more the car is being pulled foward.

Well, it depends who you are asking. From what I understand, the % difference between the 3 different types of dynos (mustang, dynapak, dynojet) are not that far off from one another.

Now, that being said, my stock dyno number (171) was wheel horsepower, so if we assume the 10% increase on the Kleeman Booster Kit/Headers number that pugguy got (183), that would come out to around 201 hp at the wheels. So that's a 30 hp increase at the wheels. That's good, but that's also under the assumption that there is a 10% difference in mustang vs. dynapak dynos. I would figure more like a 3-5% difference (just to account for wheel weight).

Every time you describe your driving experience I get so excited, I just can't wait but I have no choice right now. As far as the WCF goes, it's not something on your car. It's a corrected value of your dyno based on ideal weather conditions at the time of the dyno.

Wow this guessing stuff can get you dizzy...... Thanks Drex for try'n to make some sense out of this. No wonder everytime someone mentions dyno #'s people want to see before as well. When I finally get the install I'll post both before and after so we'll at least have a reference of gain. Pugguy, 204.9(corrected) at the wheels is the sh*t, I'm so excited!!

From what I've read and researched so far, it seems that the weather correction factor gives the amount of horsepower during "ideal" weather conditions, but how often are there ideal weather conditions anywhere.

The 183 Max Power that was shown on your dyno is the actual amount of power that you got from the two parts, not the 204. The 204 hp is based on weather correction factor, in which the car would travel during "ideal" weather conditions...Sorry, cuz I hate to be the one to reign on anyones parade. Either way, the 183 is still a very good number and quite possibly would translate to near 200 on a dynapak. Main thing is you're enjoying your car now.

This is some information I found, while doing research, that is the most important part when looking at dynos (hint: most important factor isn't the max power).
...As a golden rule the numbers from one dyno will not match another one, particularly between different brands and types. Even within Mustang brand, we have to be careful that exactly the same inputs are given to obtain the exact same numbers. Mustang dyno's are extremely accurate and extremely repeatable (to less than 1 HP), furthermore our unit has weather correction factor built-in (i.e. the values are corrected to SAE numbers and the weather conditions will not affect the results, whether the test is done on a cold winter day or a hot summer day the results will be same). The max HP number is not the critical issue either, what's important is the shape of the torque curve (horsepower is a function of the torque and it is always calculated HP=TQxRPM/5252) and air/fuel mixtures for safe operation (appropriate fort the application whether it is race or street or whatever)...
