Whats up guys,

I did a baseline dyno today with the local M3 + M4 Crew. A ton of nice cars... Had a lot of fun and was happy with my baseline numbers.

Car is bone stock aside from an AFE open air intake. 93 Octane.

Best numbers out of 3 pulls: 273 whp, 298 wtrq

HP numbers right around what I expected... Torque was pleasantly higher then I expected. I knew the car was torquey I told the dyno operator to rev to ~6.7k but looks like he let off a little early on the runs... not a big deal since power starts to dip past 6K anyways.

Can't wait to throw on a JB4 w/ bluetooth



Uncorrected #s were 279 whp, 305 wtrq

Here is mines for comparison

2015 335i M6, the low number is stock with AFE and MPE only.

very nice ^^ ... whats mods on the 390 whp pull? A little unusual torque is lower then hp on the higher pull - trying to keep it easy for the clutch?

Looks good.. Remember a dyno is just a tool and don't get concerned or focused on the raw numbers.. When you do more stuff to the car make sure you go back to the same dyno, and then you will get a good idea of power made, etc..

Yessir correct... Will be throwing it on the same dyno with future upgrades

Pure Stage 2 with ER charge pipe @ 15psi.

Stock FMIC and Clutch are the limiting factors. And the tq is limited because of the clutch.

I was wondering what the difference between STD and SAE correction factors was and here is a good read. SAE is typically 4% lower read than STD. All dynojets using the same CF and correctly installed and calibrated should all read the same regardless of location or climate at the time.

That may work in theory... but it is never the case. All dynos read different. I am aware of the difference in STD and SAE. I am not new to the car scene and have dynoed multiples times (this specific dyno about 6-7 times.) I prefer the standard correction factor because I've always used it and it seems most people around here use that including the big names/tuners. Just FYI my SAE numbers were just a couple points lower. Your #s would have definitely been slightly higher with the STD correction factor. If you are still in contact with the dyno, you can probably call them and they can pull those graphs... its just an option on the dynojet system.

Like stated above its just a measuring tool - I really want to see what the baseline was before getting JB4 and additional mods.

There was a JB4 tuned M5 on race gas that made 500whp on map 7 I believe. Another tuned M4 (running a pretty high map/boost) with intakes made like 470-480whp. The FBO and tuned e46 M3s were all around 290-320 whp so it definitely isn't a happy dyno, but accurate.

Very nice #s BTW.

do you know what the max torque limit is on these OEM clutches? I'm running JB4 on map 1. I believe the torque goes to over 400 with map 1? And does anybody know if stage clutches are out yet for this chassis?

Thanks

Great to see some realistic baseline numbers - and even on a Dynojet. 20 crank hp over advertised is something I can believe in

With PS1, FMIC and DP but stock boost/flash I dynoed mine at 286whp...

I haven't seen anything but I am not looking too hard, stock clutch is still holding at 400 wtq for probably a year now. Looking at real oem I think there is a chance I can do a 550i clutch when it comes to that.

Stock clutches seem to be pretty stout. I'm now full bolt on, tune and e40 mixture. My highest dyno pull was 400whp + 473wtrq. Happy to see clutch still grabs like a MFer.

Thanks for the response. Is a 550i clutch direct fit?

lol that's good to hear. Running map 1 now. Been worried about throwing the downpipe on cause I thought it'd be too much power but that seems promising. Thanks for the reply

The 550 is direct. I'm doing it now on my F10 N55. I had 500wtq on my stock clutch and was getting slip. Though the stock clutch is extremely resilient 473wtq is past its limits, be careful. A new clutch is about 400 bucks and a new DMFW is about 1200 not including labor. Don't glaze your DMFW from 473wtq. Get the 550 clutch soon or tune down your wtq asap. In the pics you can see the minor hotspots from 500wtq.

We've found that 430wtq its at its limits and this is with a CDV mod/delete. The 550 clutch should be good up to 550wtq maybe even 600. I'll know soon.

Great info boss.... Thank you for sharing.

Thanks for the response. I'm not planning on making that much power. I guess my plans are to stay with JB4 Map 1 as I'm very content with the power. Map 2 is a stretch for me. But should I be okay with map 1 on a stock clutch. Obviously i understand it won't last as long if the car was stock. And yeah DMFW isn't cheap lol. If this day comes for me do I have to buy a 550i DMFW or is the F30 flywheel good?

Map1, 2 or 5, if you're over 430wtq it's only a matter of time. That said, if you're not hitting the clutch hard from a dig or wot from a low gear or don't let off when you feel a slip, the clutch will probably last a long time at 473wtq. Flywheel will most likely be chassis specific it's the 550/335is as for the clutch itself that can be used on the 335/535

Thank you for the insight. Greatly appreciated!

Awesome. This is what I'm looking to do. Also 6mt. How is the clutch holding up? And who tuned it?
