Yes, we've dynoed a few, they're making impressive numbers. I'll have some dynojet numbers up shortly.

I dont know how to tag a forum user, but "The D.A." have a thread with dyno results: http://f80.bimmerpost.com/forums/sho...5&postcount=49

tom @ eas: Is it the same dyno as in this run: http://f80.bimmerpost.com/forums/sho....php?t=1003735

Standard M4 (421whp & 410wtq) compared to ZCP M4 (440-450whp & 440-451wtq)

The ZCP is making great power. I can certainly feel it as compared to my old non-ZCP on stock boost.

I will have a baseline dyno soon.

That's one of them, here's some dynojet numbers to base from that session:

2016 M4 ZCP, baseline


And comparison of M4 vs M4ZCP:

Comparison of M4 vs M4 ZCP - baseline


Hope these help.

Are those at the wheels?

These are tested on our in-house dynojet, all numbers are at wheels.

Wow! So both the standard and CP car are making almost the BMW quoted crank power at the wheels? (if I'm reading them correctly)

Appears that way. BMW seems to be going this direction since the F10 M5 numbers were first released.

Caution on how you read and interpret those. STD correction factors were applied, so if those runs were done on a day hotter than the standard, they'll be artificially inflated. If they were done on different days with different conditions the delta between them will not be constant either. The proper way to measure the car is without any correction factor applied.

SAE j1349 correction:
29.23 in/hg.
77 degree temp
0 percent humidity

Standard (STD) correction:
29.92 in/hg.
68 degree temp
0 percent humidity

I wonder if the JB4 would make that much more power on a ZCP car?, or probably not I'm assuming. It's the same parts probably just a pound or two of boost?


Not discrediting anyone but I'm not sure anyone can feel 20HP

Exactly.

The 2016 S55 ZCP and non-ZCP are basically the same engine. One is factory-tuned with a little more boost than the other. BMW might have been holding back a little power in valve overlap and might have revised cam angles a little to gain some more power, but other than that the end-result of tuning for max power will be about the same. Same exact potential.

And only after 5500 RPM, per BMW. Peak boost remains unchanged but tapers off slightly less approaching redline. But that's according to BMW's shitty charts they released which don't mean much anyway.

Cool, thanks!

Looking forward to seeing that..

Soon as I'm over 1200 miles, I'll be in to dyno Tom.

I wouldn't put much stock in BMW's "dyno charts". Initial dynos show gains throughout the powerband. I'm waiting to see more graphs as well as my own baseline, to know for sure. Also, I'll be able to datalog my ZCP soon; that alone should tell me a lot.

BMW seems to do a "soft release" on new engines and get a bit more aggressive with tuning as production matures a bit.

Here's an example on a 2008 E90 M3, 80K on the odometer. Car came in to be supercharged and received a pre-dyno and found it to be a bit on the low side than other M3s, barely cracking over 300whp. With the scanner, the M3 was found to have very old 100E software loaded(circa 2008, never updated since driveoff). A quick software update to 231E found a ~20whp gain shortly thereafter - nothing else changed, still strapped to the dyno.



Partial gains can possibly be contributed to clearing of adaptations, but still shows BMW leaves power on the table on early releases just to be on the safe side.

Some exciting things coming down the pipeline soon.

If you can get a winpep8 runfile you could share, I'd be happy to overlay it with my non-zcp 100% stock baseline so we can get some idea of a comparison.

Awesome. I will get it for you when I do mine. Is your non-ZCP a 2016?

Correct, 2016 F80, 7/15 production pre-zcp. I have 3 runfiles stock just after 1200 mile service.
