Ok,maybe not so impressing for you E55 W211 guys out there
But for being a W210 E55 with only Exhaust,ECU and Kleemann headers these are some quite impressing numbers
415,5 Hp/5603 Rpm and 580,4 Nm/3608 Rpm at the crank in my quite light E55 with a curb weight at only 1620 KG transformed my car from a fast car to a really fast one

I actually didn't expect this big change after mounting a pair of Kleemann headers after running with ECU and a full flow exhaust for 6 months now. But I'm REALLY impressed how much faster the car is now. 4000 Rpm and up to 6000 Rpm = WOW. Or 180-265 Km/h in 4:th gear = WOW again Compared with the stock manifolds.

The people at Kleemann was really impressed with the numbers. And if I would guess,adding a Kleemann Sport Camshaft would place me around 440-450 HP with a new ECU. And if things go like I plan I will add a Kleemann S/C next spring, and I guess I'll be blowing their stated 540 HP since I guess the Supercharger ads more then 90 HP, I would guess I'm more into the 560-580 HP range I think I have a really great example of a W210 E55

I should say that I'm running Shell 99 Octane fule that we have over here in our gasoline stations

Great numbers! That is a very nice torque curve!

What correction factors did they use to get those figures 'at the crank'?

Thanks guys

I actually don't know about the correction factors more then that they said they did a pull and then let the wheels roll back/slow down and then they measured it somehow . Maybe someone would like to guess?

Very impressive numbers
