CP Owners - please can one of you dyno your car?

[stealth.pilot]

Coldlist's contacts say the CP tune is same as Eurocharged which means 70hp increase not 15hp.

I would love to validate this before my car goes into production. I didn't feel it in my test drive, but I also didn't rev it to 7250rpm.

Maybe @Nate@IND can help if @attygunther is up for it....

Much as i want it to be true, I dont think this:

equals this:

With drivetrain loss I believe it's pretty darn close to 700hp @ crank.

I wouldn't say throttle response has changed, but you can feel the 560+ torque down low as significant increase from 2.5-4k range

I don't think so either. If it did, I would order the CP.

I don't think these guys would want to dyno until their broken in. As deliveries are just beginning, we probably won't see dynos for a few weeks.

With only 250 miles on the clock, I've got a way to go. Yeah, yeah... I know I need to get some miles on this baby! Weather has been so nice lately that I can't ignore my other rides!

You have a nice selection.

i would say 70 hp is a bit to much, of course hope so.
But i am sure the m-gmbh made sure that the Cp cares do have the extra power..

I would prefere v-box times 100-200kmh or 62mph-124mph. That would give us a better information than dinos with certain errors.. (including graph)

I think the likelihood of it being 70hp is as low as it is being 15 . It will be similar to the gains people have gotten with the N55 power pack approx 30-35 HP all up top by the engine holding torque closer to redline . This will result in a car that feels much more peaky between 6-7k rpm which is just how a British magazine reviewed the CP on track . This is exactly where this car needs extra power , not in its ridiculous midrange . The tunes floating around are Modified development files, at least they better be for what people are charging lol. As far as the other aspects of the CP it all goes to an individuals taste and whether the car will see track time . Even not on track 20% firmer damping / spring rate that is OEM developed and tuned is superior to putting "lowering springs" on a car performance wise . And I love the fact the MDM does not intervene readily . I have driven my E63 M6 DSC off daily because of it being so intrusive . I'm a hard core track guy so I like counter-steering . I eagerly anticipating my CP M6 which is being built the first week of Sept ! I will do thorough dyno/60-130 testing etc once broken in . The performance exhaust is the stock exhaust with no baffling ( my friend did this to his E92 M3) . Only 20% louder than stock and very tame at low rpm , but sings at redline and on shifts . I think it will be perfect since I'm planning on doing DP's !

so why exactly would BMW advertise 15hp more if it was in fact more than that?

This puzzles me too. On the N55 performance kit they advertise it as 20hp and mustang dyno says 25hp. So it's pretty close.

If we believe what Coldlist's contact and some others here are saying they aren't off by 25% the claimed hp is off by 200-400%.

[kylek13]

+- 20% is reasonable, its not 70hp....agreed

Not really 25 whp on a mustang dyno is way more than 20 crank HP . Again just like the "stock" 560 it's the minimum hp it will make under any conditions , 100 degrees , high humidity etc . It certainly behooves a company to deliver more than advertised not less . I'm essentially saying it will likely be 20 whp difference or 30 crank .

This has to be the most intelligent post about all of his on this entire board.

And guys-STOP believing these Dyno results. Without being willing to get into another huge debate on here, I will offer a few insights: You keep seeing pics of cars on the Dyno with hoods open. This is A #1 "no no" on the F10 M5 and you cannot properly Dyno these with the limiter as you can't run 1:1 (5th gear) nor is anyone doing 1:1 on wind speed, which will cause the DME to do all sorts of weird stuff with throttling up and down (data logging shows this clearly while on the Dyno-most Dyno operators don't "bother" to log data while running the cars on the Dynos). And reading this some guys will say "well you can still measure the "gains" even if the bottom line numbers aren't accurate"-INCORRECT. Because you are ignoring the variables, ALL of the results will be suspect, including the base-line runs, therefore the data is flawed 100%.

Whew! Like was said above-VBOX will show power differences better than Dyno-although of course there are many variables that affect the speeds as well.

I think that this was said perfectly above, in that it really all depends what you want in a car as an individual. There will be slight differences in power, feel and sound. Get what you like. Tiny little changes don't really mater. I for one am only getting the M6 comp pkg (mine is being built 1st week in Sept as well :-) because I just like to "know" that I got everything available. Thinking otherwise is what causes idiots like me to trade these dang things every 6 months!

[stealth.pilot]

But Coldlist - if you know you got everything possible you're deluding yourself. You didn't get CCB.

[greentrbo95gst]

Dynos can read all over the place depending on the type of dyno, correction factor, altitude, weather and even oil temperature of the car. Dyno session needs to be on the same day with pre-lci and lci cars there at the same time. We all saw a wide spread over dyno numbers on pre-lci models. I have a feeling this is a mini battle we will never win.

But really, tell us how you feel about Dyno's ColdList.

[RPiM5]

Why don't we just get a 2013 M5 and a 2014 M5 with the Comp Pack to race? Problem solved, no?

70 HP are you kidding NO chance.

[greentrbo95gst]

It's definitely possible to gain that much from raising the boost, but not in a piggy back format. You need to adjust the fuel/ignition maps as well, which means cracking the code ad doing a full tune. I am pretty sure with piggy back adjustments our ECU's freak out at a certain point and start pulling back.

Hahahahaha...YET!

Nah-I should have said...anything that I give 2 sh*** about.

Agreed. Most probs are with OPERATORS.
