rotating maf

[cob99]

anyone know if this works i gues its called the darkwolf mod? i dunno but i have a full bbk and someone told me to rotate it and i will get more power if you can help i app.

 

[Badd GT]

it will either work great or will not work @ all.
i had an 01 GT it worked with & my 02 it does nothing.

best way to tell is run the very lowest octane gas you can run & get very little or no ping...........then rotate maf if you ping worse after rotating you are running leaner.........therefore you have gained power.
then put in some new high octane gas to get up to level with no ping.

This mod will only make a difference if you have a cold air intake that goes into the fender. The reasoning is that the air coming in has to make a serious bend before it enters the MAF and the air is metered incorrectly. So if you turn the MAF 90 deg it will cause the reading to go leaner than before.

I did the mod and dyno'd it. At peak it was 10hp but in other areas on the graph it was a lot more.

see i do have a 90 bend into the fender so should i try and rotate it , but the car seems to run fine the way it is or should i give it a shot

10 hp? what was ur baseline? that seems like alot. i had a cold air but i took it off cuz i heard it was gonna make me run rich now im debating on putting it back on. i have an open element under the hood right now. should i go back to cold air with darkwolf i guess?

 

[cob99]

i would try it i am gonna try rotating it tomarrow but i hate hacking stuff you have to drill 2 holes in the cai but oh well if it runs better ill try it and reply if it helped my car

 

[Badd GT]

i dont have a before dyno......but i did dyno my 01 with pullies & a densecharger w/rotated maf it was 245 hp/295tq.
it is worth trying if you are willing to buy higher octane fuel.

I had a MAC CAI before I got the blower. I tried the darkwolf mod. It didn't make a difference IMO.

 

[MUSTANGLANCE]

The darkwolf mod made a huge difference for me. I wrote several very lengthy threads on my results. Do a search and hopefully you can find the info. You might do a search on my name if you are not finding any results. I got rid of my POS MAC CAI and got a K&N FIPK Gen II and like it much better.

see i already run 93 octane so i think im gonna give it a shot i just hope i wont ruin my cai thoe

 

[gtrackd02]

So you rotate it how far around? 1/2 or 1/4 turn? ?????

 

[gtrackd02]

which way also?

 

[cob99]

i am not to sure but this is what i was told you have to rotate it 1/4 turn so the elec. plug is facing the valve cover , but they say only do it if you have a 90 degree bend so good luck tomarow im gona try it

 

[SilverBullit99]

I took my car to have it dyno'd and the CAI and the 90 turned MAF were already in place. The shop was curious so the put the MAF back to the original place and after a long cool down period they dyno'd it again and the HP dropped 10+ and the A/F became much richer.

Here are the results:

 

[cob99]

hay thatnks for that chart what cai did you have i just did main and it semms to run better

 

[cob99]

i did th wolf mod and i easily picked up like 10 hp feels strong ass a mother------ i would suggest tring it made a fealable (dont know how to spell) difference

 

[Badd GT]

i tried all 4 positions (yes upside down also).
what worked best for my 01 was 1/4 turn toward passenger fender well. this means the maf electronics is aiming @ passenger fender instead of up.

hey cob.....did it start pinging in 3rd gear under wide open throttle?

 

[Jonny'00GT]

Just so I'm clear...the concensus is to rotate the MAF 90* toward the pasenger side fender wall. Is that where you had yours for the Dyno Runs SilverBullit?
If this creates a lien condition, would I benefit from bigger injectors to off-set?

Currenly I have MAC:Shifter, Cold-Air, 70mmTB and 2.5in. Cat-Back arives Monday.
Thanks!

Ok...I tried it. Now I'm noticing a slight hesitation when I initially get on the gas and a loud sucking sound...is that normal?

 

[SilverBullit99]

Yes rotate it toward the passenger side fender. It was a MAC CAI.

 

[Jonny'00GT]

Mine is a MAC CAI as well. Does your car heasitate or Bog going from off throttle to on?
