Ryephile Dyno's R56
This morning I stopped at my buddies at Advanced Chassis Dyno in Troy, MI. Andy the dyno operator has been my main man getting good quality dyno data in years past, and the R56 will be no different. Detroit's low elevation and mild climate leads to a consistenly negligent SAE correction factor, meaning there's minimal difference between raw and corrected data.
Here's the money: 170wHP & 202wLb-Ft! This is at the wheels! For reference, my bone-stock '04 MCS had baseline pulls of about 150wHP & 140wLb-Ft. This monster torque clearly demonstrates why the R56 MCS pulls harder than any R53 to date.
Here is a representative plot transposed from my Auterra OBDII Scan-Tool. This is showing Boost in KPa versus RPM. For the PSI crowd, this shows ~15psig between 4,000 and 5,000 RPM, and then a low of 9.8psig at 6,100 RPM [not counting boost threshold at low RPM]. Just like Helix and Grassroots has shown, the R56 MCS has a bit of a tough time figuring out what boost to run around 3k RPM, dipping between peaks.
I'm way impressed with these figures; though that said, the car does feel this strong. Big thumbs up to MINI for a hearty evolution!
Cheers,
Ryan

Yes they are some sweet numbers. Yes I have already lowered the car; a mandatory move IMO so it looks proper: Check out this thread in 2nd Gen Suspension

I agree about the mandatory lowering, the R56 looks like 4WD out of the box. Your car looks pretty tight now.
BTW, it's cool to have you back posting more on here. There's been like a Ryephile lull going on.

Just don't let me see any threads with the whole front of your car disassembled, and you converting it to a supercharger.
I'll send Sid over there to smack you around some.
...and with the numbers you just laid down, I don't see that happening.

I know very little about interpreting this kind of data, so I hope you don't mind some simpleton questions.
1. Is it correct to think that this means there is little point in going above 4,500 RPM, and that much above that is actually detrimental to performance?
2. Does the HP plateau beginning at around 4,500 RPM mean that with better breathing, it could put out a lot more power -- assuming one could keep it from overheating?

Regarding the second question, remember that HP is just a function of torque as it relates to engine speed. So the leveling of power is really a reflection in the dropping of torque. If you change the breathing you'll affect the whole torque curve. In the old days you picked your prefered rev range and maximized torque there, but I think nowadays with variable length intakes, variable resistance exhausts and ECUs to tweak the boost, fuel, and spark any way you want to, folks can deliberately tweak each part of the curve.
If I had to make a guess, I'd say after driving my R56 MCS for a couple of weeks, that since the car likes to operate in the 2300 RPM zone (ie, it's not struggling in any gear to motor there indefinitly), it could be there was some sort of compromise make in the tuning to optimize fuel mileage in that 3000 rpm dip. Otherwise, it looks like a weird unfinished mapping of fuel.

Ryan, how does it compare to a '05+ Stock MCS with the shorter gearing? That dyno comparison has not been provided anywhere, yet. To me there is simply a huge performance divide between the R56 and the pre-2005 MCS. Heck even the '05+ R53 feels faster than any stock '02-'04 MCS.
How does the R56 feel approaching redline? Does the car loses steam at the top of the power band? Just curious.
It seems to me the R56 will be a great drag car.

That's a lot of torque, 270 nm from 3800 to 4500 rpm and not a lot less even under, from 2500...
I thought Mini claims 260 only under overboost, it's like yours is always over!!!
Can you post some in-gear time, to compare them with other R56 and R53? A 50-90 kph in 2nd or 100-130 in 3rd would be the best!

The R56 pulls smoothly to redline. It does not lunge for 6500 RPM like a Honda S2000 or my turbo R53 did, but it doesn't wheeze to redline like the VW mk5 GTI either. When driving quickly, there's no reason to shift early. It may feel like a diesel down low, but it's still a gas engine.
My stock '04 MCS:
wHP peak: 152 translates into 172 HP SAE
wLb-Ft peak: 140 translates into 159 Lb-Ft SAE
My stock '07 MCS:
wHP peak: 170 translates into 193 HP SAE
wLb-Ft peak: 202 translates into 230 Lb-Ft SAE
