BIG GAINS! My Tuned RENNtech R1 SLS Black Series on the Dyno

Πριν 2 μήνες

The gains from the RENNtech R1 package for my SLS AMG Black Series are even more impressive than we expected! Both the horsepower and torque are up by a surprising amount, and the sound under full loud on the dyno is something incredible to hear, but then the downshifts.... is there a better sound than this?!
Two months ago, upon arrival in Germany we took my SLS Black Series in its totally stock form to the dyno at REM to discover how much power it made. Officially claiming an output from the 6.2l naturally aspirated V8 of 631hp and 635Nm, we were disappointed that the results were approximately 50hp and 40Nm down from where they should have been, but this is where RENNtech come in.
There are two aspects, the first was taking the decision to order the parts for the full RENNtech R1 package and the second to ascertain where the losses are being caused in the system. With the latter still to be discovered, step one has been the installation of new headers, 200-cell sports-cats and an ECU tune which not only makes the car sound incredible but has also significantly increased the power output.
With a claimed gain from the R1 package of 44hp and 43Nm, the results are impressive as they take it even higher! The final figures from the dyno run on the same machine and circumstances following the RENNtech upgrades are 636hp and 653Nm; up both 57hp and 69Nm in total.
The good news is that these take us back slightly above the official factory output but we do still have the discovery to make as to why it's down to begin with. Part of that is potentially to do with the resonators at the back end of the system, which is something we'll be removing to investigate in full when there's an opportunity to do so.
Thanks as always to Lukas and the team at RENNtech Europe, great guys and always doing a fantastic job with everything! renntecheurope
Thanks for watching, Tim

After taking my SLS Black Series straight onto the Nurburgring with the RENNtech R1 upgrades, I knew there was a lot more power than before, but I didn't expect it to be quite so much! The most incredible thing back on the dyno though has to be the downshifts, the sound is unbelievable.

My M156 hated to idle... It is a high compression V8 with alot of intake manifold vacuum, and from my experience are prone to sucking oil vapors through the PCV valve from the crankcase. My car had over 100,000 miles, but after fitting a catch can and a new set of OEM injectors the car picked up a chunk of HP (+80hp). Also the factory cast magnesium intake manifold is prone to cracking and leaking, probably not an issue with a car with as low a miles as yours but I would start with the intake manifold, intake manifold gaskets are also prone to leaking.

The SLS Black Series is the Mercedes take on a muscle car! The sound reminds me a lot my similarly tuned 7.0 L C6 Z06. Of course there are huge differences in luxury. That SLS is a gem of a car.

Not sure who told you the SLS made 631 wheel horse power, but that is AMG’s rating at the crank. Also not sure what kind of correction factor they are using or what gear they are dynoing, plus there are so many settings that could be off, but again 631 is crank horsepower, you are measuring wheel horsepower

Sounds more like a Ford V8, then a Chevy V8. My guess is that it uses a DOHC style engine, with possibly a flat plane crank? Sounds amazing, to say the least :-)

@Shmee150 in regards to the lower power shmee It is an N/A car so it might be just what you get. You get the plugs changed, I have the m156 in my c63 and they are very sensitive and love fresh plugs! Also the camshafts and Hydralic lifters (tappets) wear out fast, even at low milages on the standard c63 m156 engine, the sls has upgraded tappets and the black series even more special coated tappets, however It may be worth taking the rocker covers off just to inspect for piece of mine. I have done this on my c63 and the intake camshafts both sides have slight pitting on them, Its on 64K millage.

Still with the mixing of Rear Wheel HP v Crank HP. The SAE Correction factor is to standardise altitude and climatic conditions. It doesn't factor driveline losses through the transmission, clutch, diff etc You can approximate this loss, but you're comparing the factory Crank figure with the Rear Wheel figure. Of course there is a power loss. If your dyno operator is telling you he can correct for that, he's lying. Otherwise post the SAE Correction Factor numbers to show the two runs, base and with exhaust work, and they should be the same.
