Hello,

Thought I would dyno the car. Taking bets & guesses on what I'll put down. It's around 6 PM EST. I'll update this accordingly. Will be done via Dynapak hub mounted.

128k miles 2013 6MT stock n20 block stock clutch, stock flywheel, etc

Mods from sucking in air to exiting tailpipe:

aFE grill scoop
aFE Magnum Force Stage 2 Intake
FTP turbo inlet
Go Fast Bits DV+
FTP Turbo to Intercooler pipe
ATM Intercooler
FTP Charge Pipe
eBay minus kitten downpipe (circuit werks if anyone really wants to know)
OEM mid-pipe (no cats on n20 variant) + removed resonator
335/340i Active Autowerks muffler

Tune:
Stage 2 BM3 OTS 93 Octane Map

Additional functional things
Stage 2 fuel pump Walbro 525 Fuel-It Pump
BPM4 EKP - doesn't overheat with the increased wattage of the upgraded fuel pump (plug and play when coded via VIN)
Precision Raceworks Coils

280/307 was the highest. Graphs were all the same.

You need to provide your stock numbers for us to guess, but the math already exists. You will get close to 22%HP / 25%TQ more than your stock numbers.

Based on factory numbers of 248hp * 22% = 302hp * 15% drivetrain loss = 257whp. Maybe you will get more than 248hp stock, as these tend to be under rated, so if you add another 15-20hp then likely best case around 275whp.

Goodluck with the tests.

FTP Turbo to Intercooler pipe - won't impact power
FTP Charge Pipe - won't impact power

I'd guess 260-270 whp

Was lazy when I made the list here at work. Thinking too fast before hit post. Will change it soon. Thicf30 made ~270 at the wheels with auto + catted Downpipe.

Will do 2 runs with the stock tune and mods, then 2 runs with stage 2 93 OTS tune for comparison.

279whp/303wtq

Updated with chart !

Dammit. I was so close!

Real good numbers though

[GreenF30N26]

Cool. A little higher than I expected. What were the stock numbers with FBO only no tune? What's next, draggy for 1/4 mile time?

Wasn't able to flash it to stock. Was having issues with the wifi agent and bm3 at the time. I think I broke my wifi module within my phone as dropped it at the Dyno 😩.

My best time at the track was 13.7 at 102. I was scared to really launch the car and didn't want to break anything. I also didn't know launch control existed with the 6MT until after.

I think gearing alone would change this as a shift from 3 -> 4 is needed with about 60-80 feet to go as your stuck at redline at 92-95 mph. A simple raise of the rev limiter to 7600 would help wonders.

I am not surprised! Manual Trans rule! Not as much driveline lose. I know in this traffic around DFW it sucks most of the time but I still like driving it.

Dynapack Dynos read "high" because they are connected to the hubs, instead of being strapped down to the wheels. Without a baseline, I'm just spitballing it, but I would take off about 8% for Dynojet numbers.

Otherwise great build and thank you for posting.
