Power Distribution on a Dyno

I asked this question on the Sedan Forum, got a lot of view buy no replies. I'm hoping to get more help here!

I’m getting my C400 dyno’ed for baseline HP. It will be done on a Maha Lps3000 chasis dyno. I plan on getting a OE Flash tune after and hitting the dyno again to see the gains. My question is this:

How is the power between rear tires and front tires distributed? I’ve looked online and couldn’t find any info except for two articles saying it was 45% front 55% rear. Other then that NOTHING!

Can anyone here confirm this or point me in the right direction?

Thanks,

Alex

It was 33 front 67 rear for C400 and C450. For C43 it is 31 and 69.

The C400 was the MB standard 45/55.

It is considered 'fixed' but breakaway clutches can shift up to 70% front or rear, and the brakes are used to manage the rest.

With the car in dyno mode, the electronics will be shut off, so you should be good to go.

Thank you both! So what is the final say? 45/55?

The reason this question came up was because I was told the shop would be able to adjust the dyno to the specific vehicle distribution. Making the results more accurate.

It doesn't matter how is the power distributed, every dyno will read different from others. What you should do is dyno before and after on the same dyno and look for HP/TQ gains, power curve, % difference, AFR's, etc...

Just make sure to put it in dyno mode

The more rear-biased split is an AMG thing (well, at least marketed that way). The C400 was pre AMG Sport/43 models.

Yes, that's why I asked. The dyno shop is down the street from my house so it will be easy to get a before and after comparison when I get the tune. I youtube'd a video for Dyno mode. So we should be good to go!

Thank you for the link! I'm happy with my car, I really like the fact that I don't see too many of them! Everyone thinks C300 until the see the badge!

Also thank you all, I've posted a few performance question in the (W205) Sedan section with NO replies at all!

Thanks again,

Alex
