Amg63-

Hey guys first post here. Recently
Got a 13 c63 p31 sedan with eurocharged v5, been loving it so far.

I was just browsing through your YouTube and came across a video where I'm very surprised by the results.

It says the e63 biturbo is tuned to 630hp. I know it's a 2014 which means it's also awd which I'm sure is robbing it of power and adding weight up top, but I would of still thought with those cars being much more powerful after they are tuned it shouldn't even be close.

It seems with just a tune and intake
The c63 either keeps up beats the e63 tuned biturbo from a rolling start.

Anyone else very surprised by this?!

Also note: there are 2 passengers in the c63 and only the driver alone in the e63.

I have a p31 with a eurocharged v5 tune and row air box and i am dead even with a stock c63s

Nice, I have the same mods done on my 13' p31 sedan. After the v5 tune the car felt way faster than stock despite me reading here that there are no gains to be had from tuning a p31. I also tested a standard tuned car with v5 and for some reason it didn't feel nearly as fast as a p31 with the v5 tune. I guess the difference must be how the lighter weight internals of p31 respond to the tune possibly making more power than a standard tuned c63.


I don't know how other tunes compare but the v5 even being just an off the shelf tune feels like it gained a good 25whp and major torque as well (guessing around 30wtq).

Are you even against the c63s from a roll or off the line? That's very impressive.

Still, I would of thought the e63 tuned biturbo should still be faster than a c63s or tuned w204 p31 c63.

There's no way a properly driven tuned e63 biturbo loses to a n/a C63. There's a good 10mph trap speed difference.

My CL600 is right there with a lightly modded C63. A stock E63 pulls away, a tuned one flies away. Different power levels completely.

This vid looks like the E driver wasn't starting in correct gear or whatever the case. The C gets a nasty jump and the E is coming back hard, that's driver issues.

^ that's exactly how I saw it also

The first run is the only one where the C didn't take a big jump, and the E was pulling hard on him

Sneaky quick third honk and a jump. That's all it takes.

yup this is all driver, there is no way a tuned e63 loses this it shouldnt even be close really.

A tuned c63 is trapping around 120mph. I thought I saw the bi turbos at best with just a tune only are trapping 125-126 mph not 130mph unless more mods are done in addition to just a tune? Maybe I'm wrong here I'm not sure.

Either way based off trap speeds the e63 should be a good 5 car lengths faster at least. And this was an awd model which is slower from a rolling start than the rwd models which would be even worse.

What about a tuned p31 c63 up against a stock bi turbo with the performance package from a roll?

Aftermarket tunes make the bi turbo much faster at 125+mph traps but stock it seems they trap around 121mph. In this case I'm assuming they should be about even?

Same seems to be true vs c63s. Stock a tuned p31 can keep up from a roll but once they are tuned it's game over for us against any biturbo we go up against.

You can't defy physics folks...

Can you explain?

I also forgot to mention c63 has a passenger while e63 was only the driver alone. I guess it did ok considering that difference as well.

e63 needs one thing and one thing only..

a new driver.

Also just a poorly done video

chrisridebike8

Yeah that E63 was pulling HARD. Clear road and a better driver, the C63 should see nothing but the taillights.

I've only done a 30-40mph roll and we are dead even i inch out a little, i have a really hard time getting my car out of the whole from a dig. I still need to practice that

Amg63-

Same here especially with the v5 tune the extra low end torque makes it even more difficult to launch but in a rolling situation where traction is no issue it will make you faster.

I'm very impressed that you were able to slightly pull on a stock c63s. Those things are known to be crazy fast from what I'm hearing.

Are your only power mods the tune and row boxes+filters? Would be nice if that's all that is needed to pull on one of the new model c63s lol

Amg63-

I agree even without the extra passenger in the c63 he still should of got eaten

Yes those are my only mods, i do have secondary cat and res delete but those mods don't really change anything other than sound, and I'm running PSS for tires

Amg63-

Funny I'm running the same setup including tires but without the sound mods of secondary cat/res delete.

I wish I got a before and after dyno done following tune+row boxes+afe pro dry s filters but never got the chance to do it.

Did you by any chance dyno before and after the V5 tune+row boxes+filters?

iShootYou

I so not i have a dyno sheet of my car stock with the v5 tune, before the air box and sound mods. I make 389whp on a mustang dyno
