2014 Mercedes-Benz C63 AMG Edition 507 on the Dyno
Have a look at what a lightly modded 2014 Mercedes-Benz C63 AMG Edition 507 does on the dyno.
The 2014 Mercedes-Benz C63 AMG Edition 507 is an awesome performance car, with a model name which reflects its horsepower rating. The naturally aspirated 6.2L V8 was rated at 507 horsepower and 450lb-ft of torque at the crankshaft, but what does that translate to in terms of real world, rear-wheel-horsepower?
Forum member bentz69 owns a 2014 Mercedes-Benz C63 AMG Edition 507 and earlier this year, he hit the dyno with some simple mods to get some baseline rear-wheel numbers. He posted details of his first trip to the dyno a few months back and since adding more goodies, he updated his original thread in the C63 AMG W204 section of the forum.
Baseline Numbers
Back in August, bentz69 took his 2014 Mercedes-Benz C63 AMG Edition 507 to his local dyno shop for some baseline numbers. It should be noted that when these first runs were made, the car was not stock. He had a freer-flowing air intake setup and an exhaust system devoid of the second catalytic convertor and the resonator. For these initial runs, it was 90 degrees outside with 52% humidity and an altitude of 4,500 feet – so the air was less-than-great. However, he still made some solid numbers.
The first two runs were made untuned, with the C63 AMG Edition 507 making 423 horsepower and 400lb-ft of torque at the rear wheels on the first run and 428hp with the same torque on the next run. With standard correction, those numbers climbed to 435/441hp and 411/412lb-ft of torque. Based on a drivetrain loss factor of 18%, this untuned C63 507 is making somewhere in the area of 537 horsepower with the simple mods.
Tuning the Beast
After making the untuned runs, a V6 tune was added and two more runs were made, with the C63 AMG Edition 507 laying down a best corrected figure of 443 horsepower and 414lb-ft of torque at the rear wheels. A V7 tune was then added and two more dyno runs were made, resulting in peak numbers of 451 rear-wheel horsepower and 426lb-ft of rear-wheel torque.
Those numbers might seem small for a car with light intake and exhaust modifications along with a V7 tune, but the OP points out that the tune needs to be run-in, which he did not do. As a result, the final runs could have been in the area of 10rwhp better, or somewhere in the area of 461hp at the rear wheels.
Using the 18% drivetrain loss factor, this 2014 Mercedes-Benz C63 AMG Edition 507 is making somewhere in the area of 562 horsepower with the tune and the simple upgrades.
Adding Headers
Last week, bentz69 posted an update on the progress with his2014 Mercedes-Benz C63 AMG Edition 507. After installing headers and an appropriate V7 tune for his modifications, he drove the car for a while and hit the dyno for new results. With the same standard correction methods on the same dyno, the OP’s 507 laid down 472 horsepower and 435lb-ft of torque at the rear wheels.
Compared with the untuned (corrected) baseline numbers, this Mercedes-Benz picked up 31 horsepower and 23lb-ft of torque at the rear wheels by adding a tune and headers. With the 18% drivetrain loss factor, this Benz is making somewhere in the area of 575 horsepower at the crankshaft with these simple mods and a tune.
