Interesting to see with fairly little mods the M3/M4's are making well over 500+ WHP / TQ. The EAS car (Yellow) is making damn near 600 TQ.

Gotta give credit where due, those are fantastic numbers for relatively little mods (filters / catted down pipes / exhaust and tune!)


Interesting to say the least. W204 owners may have to be SC'd just to keep up with these bad boys.

That 556/599 car.....that might be a 10 second car with some drag radials.

Illegal Machine

Sound like garbage, tho.

rentzington

That's pretty impressive!
I glanced at the M cars before going c63 but I just preferred the look and sound of the c63 beast

But those gains the m3/4 get from even just a tune may be food for thought come next purchase time

BiturboSF

Seen the videos the other day, impressive. All those cars running on JB4 Map 7 is on E85 mix, 100+ octane, or a combo of both, none of them is running CA 91 gas. The yellow M4 is on 100 octane for sure

Ingenieur

the new R&T
M4 ran 12.4/115

Motor Trend the e63 was faster around VIR than the M4
it weighed 700 lbs more lol

Just think what the new C63 will get
it has a huge head start
33% more dispacement
higher compression
better intercooling

it should be a 750/800 machine if the M4 numbers are to be believed
but they are not

Kriston

These numbers are on a JB4 map 7. So high boost and timing to compensate for race fuel. I highly doubt these guys are running those tunes on the street. Especially on stock turbos.


Either way, I want to see a reliable street tune to see what they can actually do.

RW Carbon

New M3/M4 is nuts for sure I saw one with bolt ons and a tune pulling 600whp/wtq.

I have a feeling the new C63 will be even more potent though

johnnyblaze

its well known that EAS's dyno reads a bit high....

Still, great numbers for a Inline-6. Like most people have said I cant wait to get myself a tuned/dp/E85 4.0 TT C63

CarHopper

Admit it, you're just scared!

cloverfield

Sounds like a sneezing horse but certainly goes like stink. We did 12.1 @ 119 and a 3.9 0-60 time in the manual. Feels about as fast as a tuned C63 but far more sterile to drive all-around. Shame, too, since it looks sick.

csexty3

A full bolt-on E90 M3 earlier on the same day dynoed 366whp. A base ls3 C6 put down 395whp later, also on the same day (my buddy's car). Sound about right to me.

Hopefully the shop car (yellow M4) will back up its numbers with the "right" trap speed.

Kriston

So what are these cars making with street tunes? Seems some of you are aware of these cars can make with a reliable tune and pump gas.

CarHopper

pump gas... 480/484 according to burger tuning. And that's to the wheels.

Kriston

That's some solid power from just a tune. I cant wait to run into one, see what it can do in real life.

CarHopper

My friend is running 11.9 in his stock m4 so yeah, its a fast car.

izzy63

Funny how the exhaust doesn't give that much HP in a turbo car

izzy63

Butt dyno still thinks c63 is faster

Overrated

I like the car personally. I still have to wait and see if the TT V8 C63S Coupe hits next year. If its not out by the last quarter of 15', I will have to seriously look at the M4.

dchl21

man ... these bimmers are catching up and I don't like it one bit ... maybe its time to get more hp on my 55

CarHopper

Butt dyno also wont help you when a tuned m4 starts pulling away from you. If you're stock that is...

As for the exhaust... Downpipes can give turbo cars huge gains. Such as, oh I don't know, that 5.5 biturbo gem that is in the CLS/E63 right now.

CarHopper

Yes and no.

Base models (I know who cars) but the c class is far better than a base 3 series.

Furthermore, they aren't really catching up. IMO everyone stayed put. M3/M4 can get around a circuit more quickly and is a more serious car. The C63 is just the hey I'm here having almost too much fun and will most likely still win out in a straight line battle mod for mod.

Everyone (BMW/MB) has been remaining their course...

Audi on the other hand, those sneaky ****** have been doing some good work over there lately.

Ingenieur

No way on 93 octane, at least for very long
Crank 15% losses 565 hp / 570 lb ft from 3 liter
That is >30 psi of boost at its stock comp ratio
And eff comp ratio of 30:1

Specific output of 3.1 hp / in^3

Ingenieur

Of what?
Losing 'face'?
I have a different basis of self evaluation apparently

Ingenieur

The best any magazine has gotten so far under ideal conditions is 12.1/118 iirc
Averages are closer to 12.3/117

The z28 is 10 sec faster around VIR
THE 700 lb e63,was faster
