Looking over a friends dyno results prior to and after installation of Kleemann SC and Kleemann header and downpipe exhaust system on his E55 has left me with some questions.
Dyno results prior to mod is 296.4 rwhp 318.1 rwtq(stock)
After Kleemann parts listed above dyno results are 420.9 rwhp 418.6 rwtq.
Now on Kleemann site with SC only mod crank would reach 500hp and 482 tq.
But after installing headers and exhaust one would think that the dyno results would be higher?? Their site indicates and increse of 40-60hp at crank.
With all mods on this car the numbers would add up to approx. 540-560hp at crank per their website.
Seems like the dyno results at 420.9 rwhp and 418.6 rwtq is somewhat low?
One piece of information that may be pertinent is that dyno was performed 2 days after Kleemann installation.
Any of you have ideas or input?? Do dyno results get better after some elaspe time? Dont get me wrong the beast pulls and will jerk your neck backwards, just concerned.
It seems a little low. Try driving the car for a week so the ECU can adapt and then re-dyno the car again. If you are still seeing the same numbers, I'd contact Kleeman and tell them there is a problem.
420/.8=525 Crank HP (20% driveline loss). and thats assuming its dynojet. Loading dynos is more. Those numbers are exactly where they should be, what is he complaining for?

Those are exactly my thoughts based on your figuring and really he is not complaining, was just unsure of exactly what to expect. His only questioning was the rwtq value?, he just thought it would have been higher.

Can you post some pics of your car and the engine bay as well? Who did the installation?

...............Those numbers are low when compared to what Kleemann's website says. No question about it. You want the guy to believe that a 2wheel drive modern automatic transmission has a 22% drive train loss? What will be the loss for a 4wheel drive......45%. This topic has been discussed many many times. The guy has the best s/c arround for a Mercedes. The numbers he got are the same as I and others have gotten and is indeed lower than one would expect based on Kleemann's website. The problem is, no other company is better. We need others to dyno their cars (hint hint to JamE55) so we can see if there are any better numbers. I was able to get mine up to 450RWHP and 500rear Wheel Torque by doing additional mods, but finally decided to stop chasing a little HP here and there and go for a twin turbo set up.

As I have stated many times before, B/c of the way our cars dyno we will NEVER be able to find out our true torque numbers because you cannot go WOT before 3700rpm and our peak torque is at 3000rpm so the torque will always appear low. theres honestly nothing you can do about it. the W210 E55 does not have a try dyno mode like the W211 E55s (VERY annoying). So tell him not to worry based on his HP numbers he is making the right about of power.
Their site indicates and increse of 40-60hp at crank.
