I'm looking for a maf setup that will work well with my 90mm tb.

Card maf? Or housing maf?

 

Id like to hear what everyone is running as well. Ill be needing something for my 408

 

i just realized i posted this in the wrong section. mods feel free to move if you wish.

a friend told me about using a truck maf. 85mm. It might work with a little porting.

 

Texas speed has a 100mm maf sensor as well you can look at

 

Yeah I looked into those. 250 bucks though....stock truck maf is about 50-75.

Also seen a cts-v maf is about 70. Its a card maf though.

 

You can buy all the parts to make a 100 mm maf for reasonably cheap.

Do a search on ls7 style maf.

 

Be a pal and break it down for him cuz I wanna know too

 

The maf itself is 50 something, the adapter pig tail is like 20 something, and the block to mount the maf in a 4 inch tube is like 15. You just need a 4 inch aluminum tube and someone to tig it.

 

Just searched it myself also and hell ******* yes! 100mm maf on the cheap

I know this is old, but it gives part numbers and A visual.

 

probably shouldnt post this, but if anyones is looking for a ls7 card style maf, i have a brand new one i never used, decided to go s/d on my trans am..55 shipped anywhere in the u.s. can throw in a pigtail for an extra 15

pm me

 

I thought the 85mm MAF actually had an ID of 90mm? I saw that in a post in the Gen III External section some time ago...I think a rep from FTP posted it.

 

Fwiw, the ls7 style maf is used on almost all new GM vehicles.

 

Talk to your tuner before choosing or porting a MAF.

MAFs accuracy is highly dependent on the plumbing it is installed in and porting requires recalibration in the pcm.

 

4 inch exhaust pipe MAF......

 

Is that using the ls7 style maf? I thought the air intake sensor was integrated into it?

 

I heard something about the length of straight tubing and Tue distance from the tb. Like no less than 4" of straight tube and no closer than 10" from Tb. Though that seems wrong considering 90% of intakes aren't built like that.

 

so you use a 4" exh pipe and integrate the maf into it?

 

Yeah. You have the bung/mounting plate welded to the 4" pipe. If I'm not mistaken the ls7 maf has a iat built into it.

 

Exactly what you said except without the MAF.
