C43 AMG 5.5 - 396.4HP
I wonder why you have so less power loss. On my car the power loss is about 35% and when I was searching the net some while ago, I found some Audi RS4 with similar engine power, they had even more power loss.

The RWP differs depending on the type of dyno used .
A load dyno which places resistance on the rollers to better simulate a road surface usually shows about a 30% drivetrain loss on an automatic Merc.
About 5% less on a manual transmission Merc.
The inertia dyno which has free spinning rollers would only show about a 15%-18% drivetrain loss.
There are other factors that when dialed in can effect the RWP...car weight, ambient temp and hunidity are a few![thumbs](https://mbworld.org/forums/images/smilies/thumbsup.gif)

C43/55 = about 3450 lbs, 349HP, 391 ft/lbs TQ (stock)
I know buffy has modded his engine on his CLK but so has ProjectC55 on his C43/55
lighter car with more power in every aspect, I fail to see how this would be a good race even in the 1/4 mile

The RS4 with all wheel drive will show more power loss because of the drivetrain, AWD vs. 2WD.

Also as RBYCC had stated "A load dyno which places resistance on the rollers to better simulate a road surface usually shows about a 30% drivetrain loss on an automatic Merc."
Perhaps you dyno'd on a load dyno

Well I guess there is only like 2 people on here that are in this bracket. I was asking because it would be nice to talk to others that have SC etc. So I take it, that if can get my car up to 475 to 500 rwhp I will have the fastest C43? Swaps don't count.

Do you want to get another car? Or stay in the 43 and tune it?
