RADO C250 Upgrades Dyno Figures
We just did our first round of testing with the RADO parts for the C250. We tested in 3 different configurations. We tested the car stock, with our non heat treated off-road down pipe and with our non heat treated off-road down pipe and our intercooler. We saw some great numbers so you can expect some real noticeable differences with our parts installed on the car.
I have put all the numbers in an easy to read spreadsheet so that you can easily compare everything. We will also be testing the car at Irwindale drag strip in all of the different configurations as well.
It was 83 degrees, 29.74 in-Hg and Humidity was at 33% and all dyno runs were made on the same Dynojet within 2 hours.

Those numbers suggest a very obvious gain, it's very nice to have a large increase in the mid range which is where most driving time is spent it can only be even higher especially in the top end with a tune and even a turbo swap considering you have a better IC to take advantage of if upgarding to a larger turbo and more boost and air volume 
Out of curiosity is there a way of getting numbers below 4000rpm with the dynojet used ? would be nice to see the increases from low down

These are some significant improvements and we will continue to work on this platform to get even more improvements from it. We have at least 3 more parts in the pipeline on top of what we already have released for the car.
We should have a full exhaust system available for this car by next week.
We are starting to prototype some other parts next week on the car that we should be able to have in production pretty quickly. We expect to have a pretty good catalog of parts ready for the car very soon.

The numbers from the dyno graph above would relate to ATW (at the wheels) figures usually all dynos measure power and torque this way.
The 204hp would be the MB OEM FWHP claim (at the flywheel HP) that's the way most if not all manufacturers call their output figures

Dang you guys for not getting the CEL light off. I might purchase...currently researching O2 bypasses. I cannot stand lights on my dash. I was annoyed with the TPMS light when I switched my rims out and just got that taken care of. Grrrrrr. The gains are enough for me to take the plunge to purchase. Can you say tune + downpipe? drool.....

I was interested in some dag strip numbers as well. Being that this thread is nearly 3 years old, I assume it never happened. My guess is the numbers showed little if any improvement being that the peak HP numbers were minimal with all the big gains made in an area of the power band not used at the drag strip. The downfalls of a small turbo, good response and toque, but low peak hp.
I must say the car doesn't feel as weak as these dyno numbers suggest. I just recently drove a 2015 Mustang Ecoboost 2.3l with 310 HP and it didn't really "feel" that much stronger than the C250. The performance numbers say otherwise as the Stang is a full 1.3 seconds quicker to 60mph and in the 1/4 mile traveling 102mph thru the traps vs 92mph for the Benz. That's a 10mph difference! I'd say if you were able to shift the Benz earlier WOT before the turbo runs out of steam, and speed up the granny shifts it does, it would generate much better acceleration times. I read the C250 coupe which has different trans programming shifts much quicker.

Any emission issues with these mods? Being in Cali and having to worry about passing smog is big selling point. At least for me.

Man, you need to post some acceleration vids! I would like to see how you pull against a stock C250 or C350. Seat of the pants can be deceiving. Just video your speedo from 0-60 and we can get an idea of the gains. Or Set up a race with a 335 whether it be a roll race or from dead stop. Gotta see for myself!
