I just looked at other C230 dynos and it looks like our car is about 10HP and 10TQ stronger than others. It is a 6-speed, we ran it in the 4th gear and it was pretty warm in the shop - mid90s.
Car was originaly ordered for New York and it has been driven hard since 500 mile brake-in.
Due to the dyno being used for tuning other projects, we will able to test it next week.

Stock our C230 made 168 RWHP and 175 RWTQ.
Next on the testing schedule is fully dampened larger crankshaft pulley. The prototype is complete and will be tested within next several days.
Stay Tuned!

Just a guess, but could the part numbers be different due to the size of the pulley on the supercharger? Doesnt the C230 have a smaller pulley to make more boost?

Since we do not have 200 engine here is US, I do not know if there is a difference in blowers.
M45 is the smallest made by Eaton, but it is extensively modifiied by Mercedes for M271 use.

Never seen a dyno where the scales were different like that, throws you off but the dyno is probably not calibrated correctly if it's skewing HP and Torque like that.

Just the scaling and rendering of them on the page. ...same crap happened to me, and I didn't notice before I left the dnyo shop. I would have asked the guy to fix the two scales to the same minimum and maximum had I noticed. ...but again, no error/skewing is introduced to the value of HP measured @ the wheels and calculated torque based on the final rendering onto the paper.

Perform a dyno on my SLK 200 today based on a M271 engine, 205 RWHP. Does this work out to be approx. 250 BHP ? I must say that the German guys from MKB did an excellent job.
The stock BHP of the SLK 200 is 163 HP. An 87 HP gain is really incredible. Those MKB guys are top notch !
Look at the Dyno Chart....

ones too fast according to CHP!
MKB is very good product. Typically on par with the best made here in the US. They have an advantage to getting product out earlier due to their proximity and connections to AMG.
However.....the products are VERY expensive. When I say "very" I mean typically 2-3 times US product.
We feel like our product will be superior for some technical reasons (the dampner technology) and for the price/value equation.
Thanks,
Brad

Yes and No.
Yes = yes, there has been some progress and updates.
No = nothing I am prepared to disclose yet.
The problem is that when we detail all the little steps, people get crazy anxious and start "blasting" us or making snide comments about the delay or time it takes. This is development, it is not a quick process. If it were easy, everyone would do it and there would be a ton of well engineered products available. It is hard, and it takes time and money to do it right, sometimes more time then expected and usually more money then expected! LOL
I suspect that the next update we will have is when it is ready to go to full production, which we expect to be in the next 30 days or so, but again, see the paragraph above.
Thanks,
Brad

No problem. I completely understand how long R&D can take. As far as I'm concerned, take your time, get it right and when it's good to go, I'm sure you'll let us know.

I wish Vadim would have never promised to show dyno results last week, which he later revised to sometime this week
Now it looks like in reality we won't see anything for a LONG time

Problem is that we get excited to share and know people like to see the steps. But people seem to get, well, irate, when things don't work out exactly as we plan. This really takes the fun out of the process and really eliminates the incentive to share anything about the process and development.
Thanks,
Brad

We do our best to stay on schedule, but due to the above plus issues related to vendors supplying parts on time or our need to change items, things take time.
