MAF

[ImBetterDude]

What should MAF look like lbs/min at WOT with a blower? More specifically I'm driving a 2015 phase 2 and without a boost gauge I'm trying to find alternative ways to ensure blower is blowing right, lol

Let me use mine for example.

7,477 rpm (7,500 redline)
7.92 psi (based off logged pressure gauge)
74.53 lbs per min of MAF
672 rwhp

What you at around 5000 rpm?

What you at around 5000 rpm?

Just pulled another log


7,600 (raised revlimiter)
8.47 psi of boost
74.51 lbs per min MAF
689 rwhp

At 5,076 rpm I am at 41.22 lbs per min MAF.
(but I am a centrifugal) so, lower airflow.

Just be aware the MAF PID has a cap at 86.68 lb/min. The MAF it self doesn't, and the ECU will see numbers higher than that, it's just a logging limitation.

My phase 2 2015 isn't cracking 60 lbs/min thru 6500 rpm. Which probably isn't normal right?

 

[markmurfie]

Stock 2015-17 cars peak in the low 40s around 6700. Less at higher elevations and hotter temperatures.

If you are on a larger upper pulley, with stock headers and cats, throttle body, getting high IAT2's I could see not getting more than 60 lb/min.

I'm on the pulley the kit came with, but am on catless bbk headers, VMP tune, and has been mid 60s so not that hot at all.

Maybe I need to take it to redline and will hit 70 or so.

Around 5k i am at 55lb/min and around 7.4k i am at 86lb/min.

Probably not a direct comparison as its a 2020. VMP odin supercharger with free flowing exhaust. Lund tune.

Shes gotta be making some steam at that kinda flow. I am guessing 12psi of boost or so?

im still working on a good boost gauge setup (any suggestions?)
but lund told me based on the load they are seeing, 9-10lbs of boost. Might pulley down for more boost soon.

I run a mechanical gauge in my vent, with that little adaptor part from Amazon. I am adding an "ethanol content" gauge to the other vent here soon. For a little project I am working on.

 

[Adamone92]

do you happen to have a link? that sounds like something i would like to run.

Search for this for the vent adaptor

"GlowShift Black Single Gauge Air Vent Pod for 2015-2020 Ford Mustang - ABS Plastic - Mounts (1) 2-1/16" (52mm) Gauge to Vehicle's Air Vent"

thank you! is there a certain mechanical boost gauge you recommend?
