F32 N55 Dyno - MHD Stage 2+

Not much to show since I don't have a baseline but figured I'd post for those interested in just numbers.

N55 EWG 8AT

Mods:
ER Catless DP
ER Chargepipe
VRSF 5" HD FMIC
NGK 97506 Plugs gapped to .022"
K&N Drop-In Filter
MHD Stage 2+ 93 Oct
JB4 (currently only using for logging)

Shop was around 100°F and 50% humidity

5th run made 374 HP/372 TQ in 6th gear

Car was pretty hot at that point, had a couple scrub runs due to hitting the kickdown.

Torque numbers seemed low compared to other dyno results I've seen.. I plan on running E30 soon and will dyno again.

Log from the run shown in the graph?

Also i would recommend just getting MHD monitoring moudle. If your JB4 logging speed is like the others i have seen its 10-20x slower (lower time resolution) than MHD.

Not only that, but I didn’t think MHD worked properly with the JB4 hooked up.

I LOVE MHD’s torque curve, but the tunes are down on absolute power (but more reliable)

For the record, that’s about 365whp SAE.

Time to order some boostane from Amazon Prime and use the 95map... there is noticeable difference between the 93 & 95 map...

I assume this was a typo and you meant MHD working properly with JB4 hooked up lol?

E20 map will make more power than 95 map per MHD.

Yes... Yes... "E" is king... but if he can't get it... Boostane... or better yet ... both... lol.... what "E" can I run if I upgrade my fuel pump?

E30 is probably the most common custom tune with upgraded HPFP; you can just run more boost with the upgraded HPFP. With stock turbo you can probably go to E50 (on stage 1 HPFP), which should allow you to make some more power with timing in addition to the extra boost.

365whp for a PWG sounds pretty accurate for FBO.

It's not a PWG, OP said EWG.

I also would still like to see the log from that run...

wow it's been a long day and I completely missed that part lol.

But still those are decent results for a reliable tune!

+1 for logs

is this 374hp at the wheels or crank?

I would assume wheels, if 15% drivetrain loss (from what I've read) is right, that would put him around 430hp crank, which is what I believe MHD claims for stage 2+.

The numbers look solid. The ambient heat and humidity were likely sucking out some power because your peak HP power only hit at 5500rpms and then dropped from there. The EWG N55s hit peak power at around 6000-6200rpms and then tail off. When they're heat soaked, timing gets pulled and they almost always peak at 5500rpms. This happens a lot on heat soaked N55 M2s.

If you were to have run on a 50 degree day, I'd bet those numbers would be more like 385whp/wtq.

A tapped out N55 on the stock turbo is closer to 56/5700rpm power peak. Even then, MHD just isn’t that aggressive. Note that the power drops significantly past peak, and is only making 300whp at redline. That’s just a characteristic of this particular tune.

Graph looks similar to my virtual dyno results once i dialed in parameters. I might be low by a few %.

I had a few dynos compiled from MHD and they all look the same way. Part of it is the engine/turbo - the other part is just how MHD tunes.

Alright thejeremyman9... got the fabspeed put on... definitely spins up faster... I just did a run and IAT's are too high to compare to my other log but yea it pulled a lot of timing like you said it would... I only drove it like 20 miles on the freeway so far... there is a spike @ 5336rpm... maybe I hit a bump in the road???.... well here is the log... Click here

So you are running the 95 oct map with 93 pump gas and boostane? Boost and load control look great. You do have a partial throttle closure early on but thats because you overboosted slightly. You might need some time to adapt to the DP.

Timing is decent, not too bad honestly considering IATs are very high and its the 95 map.

That does look like a bump, yeah. Unless you are 6MT it could be clutch slip, but it's kindof far into the pull for that even if you were. Even hitting a small bump can look like that (you dont have to like catch air for example, just reduce load on rear tires).

Thank You so much... so nice having you on here... yea my IAT's were in the 70's my last log back in November... Torque nms are the same basically early on but drop by 20nms when hitting higher rpms.. I figure the rise in IAT's are higher and pulled timing... I'm so use to almost perfect timing on the last log... I'm getting plugs installed in a couple of weeks when my other mechanic comes back in town... he's just a couple of blocks away... does a lot of high end cars... knew exactly what to do for the back plugs... I'd do it but not allowed to work on cars in the garage where I'm at... Here's my last log... I noticed boost is higher now and timing not as high as last log.... hmmmm... Click Here...

Yea running Boostane 8oz per tank of 93.... think'in dropping another 8oz in it to compensate for IAT

Yea... I think it was a slight bump... I have the 8AT

So in the end... I think it's gonna run real nice this November...
