I hope to run the car on a dyno in the next couple of weeks. I had run my 2007 350Z on this dyno and obtained 266 WHp (wheel horse power) with an engine rated at 306 Hp. That is about a 13% drive-line loss which is typical for a manual transmission rear wheel drive car. I will be interested in what I get on this same dyno with the SLK. The biggest issue will be tying the car down securely since the body work is pretty low and doesn’t allow a lot of tie-down options.
Also, interestingly the Nissan had wide-band oxygen sensors which were active through-out the load range including under full throttle acceleration. As best as I can tell the 06 SLK has narrow band oxygen sensors and is therefore using a map/look-up table to establish fueling during full throttle acceleration. Does anyone know if MB has gone to wide-band sensors on the newest version of our engines?
I'm older so I drive fast as I have less time left to waste.
