z32 or q45

[dazzamac]

just wantin to know whatthe difference between a z32 and q45 maf is, and whats required to fit both?

try'd doin a search but quite alot of pages worth ot stuf came up

thanks for any help

the Q45 resolution isn't as good compared to the Z32

A pulsar I mapped recently was maxing out its airflow meter (Q45) at 410-420bhp on the dyno, recently got 460+ on another with a Z32 and it still had more to go.

what bhp are you wanting if under 400 ive a q45 maf still packaged if your interested;-)

i've found a q45 with plug for £45 i think it was, was pretty cheap, was the only reason i was askin

i was always led to believe that a q45 had higher rating than the z32 hence why it is larger

 

[youngsyp]

I think this has been said before but, the Q45 is designed for N/A engines where as, the Z32 is designed for a turbo charged (twin) engine. This may affect the resolution they can manage ?!

 

[Fusion Ed]

Absolutely does. I can state with 100% certainty that the Q45 is unable to measure the same volume of air as the Z32 sensor can, what is physically able to pass through them both is irrelevant if the sensor runs out of measuring ability before hand.

The Q45 MAF is 90mm where as the Z32 MAF is 80mm so people assume bigger is better. As people have already said, the sensor is scaled lower so the voltage maxes our more easily.

 

[dazzamac]

so to sum the up.....the z32 is the way to go

cheers for the info!

So whats the next step up from a Z32MAF when using a setup that requires an air flow meter?

 

[Fusion Ed]

Good question, not had a car on a MAF make that much power yet. When it happens I shall let you know... MAF from a Cobra is one possible option, or two MAFs skyline styleeeeee

well the z32 MAF will cope with 500+ and if your at that level already, I would guess the next step would be to go MAF-less and use a map sensor
