CLK63 AMG Black Series Dyno Run

Dynojet dyno. Mach V Motorsports. 45690 Elmwood Ct. #170, Sterling VA 20166. www.machv.com

2009 Mercedes CLK 63 AMG Black Series with long-tube headers and aftermarket exhaust, aftermarket intake boxes. This run was done in fifth gear. (The dyno didn't record the very end of the run because it wasn't happy about the tires going more than 180 mph!)

seems like more power could be measured if more cooling was provided. As far as i can tell that one relatively small fan would not provide the airflow that traveling at 150 mph would provide.

@ead1017 The fans are there for cooling the car during the dyno run. The car temp stayed at normal during and after the run. You don't need more fans than that, and more fans would not make more horsepower.

@MachVDan And there is where your wrong. Cooler air = more oxygen = more hp.

[MachVDan]

@pino110008 Um...fans don't cool air. They just move it around.

is that driver relaxing or closing his ear once the V8 unleashes his muscle hahah

[MachVDan]

@AllAboutEthics Covering his ears. It's LOUD.

deutsches auto !!! :D

[NekoOfficial]

the rear spoiler is terrible...

[bmstyle]

@pino110008 actually cooler air = denser air = more oxygen particles per volume of air = more hp....

[MrTheAni]

@NekoOfficial It ruins the classy aspect of a Merc. 

[daZzleV]

ugly rims :(

[MrMnMade]

"Dont you have to put that thing in dyno mode?"

WTF has technology come too...

[818mrAlkash]

Lol its so fuckin loud he covers his ears at 1:15

[rupp023]

ohh i jizzed in my pants at 1:16

[mattnota]

i just came in my pants

[Dakay1337]

This ist the best performance and quality from Mercedes, one real reason to buy no bmw :D

@pino110008

Similar airflow to what would be generated at wheel speed would give more accurate results. In most cases as water temp rises the ecu will retard timing and reduce HP,while water temp may stay consistant on the dash the sampling rates could be much faster for the fuel/timing and it may take into account the massive rush of heat generated on a dyno pull.

@pino110008 To a point. This being most true if it's cooler air being fed into the intake. Cool air hitting the engine and radiator will only benefit the engine if it's fully warmed up to the point that the thermostat has opened up and the fluid in the block, and radiator is so hot that the thermostat will not close even if the temps of the fluid drop 10* or more.
