016 vs 012 maf meter

[barry240]

this is on my +t i have a 016 maf meter and i hear a lot of stuff using about using a 012 meter whats the diffrence ?

[thelostartof]

012 is a 3" amm

better suited for having larger than 46lb/hr injectors along w/ moves the AMM cut point up a few hundred RPM

[barry240]

seems like fuel cut happens at like 20 lbs on myne tho .maby its the freds chip

[thelostartof]

the chip does nothing to the AMM cut out point

Sorry to be a hassle, but what size would that make an 016?

[thelostartof]

2.75 or maybe a little smaller

2.48" ID I think. I can be wrong though. It was a long time since I measured one.

[thelostartof]

haha yea it has been a long time since i have had one here, and yea i think 2.5" is the size as my old cone filter was 2.75 so yea

i do have ford red top injectors so would a 012 be a good or will it over advance the timing .because of the diff in load

arent ford red tops equal to stock green tops? i would wait untill you up to brown tops or something larger before going with the 012.

i have measured out a 012 today, the 012 ist 34% larger than a 016, therefore you need 424cc/min injectors on a B230FT to match exactly for gasoline or 590cc/min for E85 (smallest for E85 is round about 530cc/min, the rest will be managed from the LH)...

Data:

016

- internal diameter 62.5mm - 2,46"
- external diameter 70mm - 2,75"
- = 30.67cm2

012

- internal diameter 72.5mm - 2,85"
- external diameter 80mm - 3,14"
- = 41.28cm2

That's a increase from round about +34%

Also an addition from someone who knows LH... (that is me btw)...

You are absolutely correct in what you are saying Stoni.

But this is my input:

To run the 012 (and make it mathematically correct) you need to use 436-452cc/min injectors for gasoline.

To run the 012 with E85 you need to use 620-642cc/min injectors. Preferrably up to 764cc/min if you want to really get some power.

But like I said Stoni, you are right in that you can run the B230FT on 590cc/min injectors. On E85 you don´t have to be very exact. Both the octane and cooling properties are better and you can get away with smaller injectors than what is mathematically correct.
