Air Flow Meters

stavros68 · 15-01-2008, 07:18 PM

Trying to find an air flow meter for my Au Windsor, does anybody know of any places in Vic that sell them?? At the moment its got the stock unit 65mm

The stock MAF is 70mm.

Can I ask why you are looking for bigger? What sort of power are you making?

Do you have an edit/flash tuner?

I think the 70mm only came out on the 200 & 220 engines, if he has a 185 or a non XR it will be a 65mm IIRC.

All MAFs are 70mm, the TB was 65mm on AUs and AU2s, and 70mm in AU3s.

Not much point replacing the MAF unless it's faulty. The stock MAF and stock injectors are good up to around 250rwkw.

Autobarn used to carry aftermarket MAFs as advertised in Street Machine etc. Otherwise try sites like VPW etc.

Correct.

Based on some datalogs i've got of the MAF output voltage from the track, I reckon the stock 70mm MAF pegs somewhere closer to 180-190rwkw.

I'm not sure the 80mm MAF on the 5.6L strokers is even good to 250.

I would be very reluctant to go to an aftermarket "calibrated" MAF when the factory 70/80/90mm MAFs are so good....and if you are going to make more than 280-300rwkw then look at SCT Bigair MAFs (using the same electronics as the factory MAFs).

Stavros.....if your not making more than 200rwkw, then look somewhere else to spend your money.

Standard MAF should be OK - just ask RedXR347. Pretty sure his MAF is standard, and he has 210+rwkw, IIRC.

I'd say closer to 230rwkw atm with the standard MAF, but I am thinking it may be time soon to go a bigger one. 90mm SVT lightning one from the states is apparently a good buy.

stavros68 · 16-01-2008, 09:15 PM

yeah im thinking about 90mm lightning one or the pro M racing from raceparts to suit 30lb injectors for $450

MADED-6 · 16-01-2008, 09:48 PM

yeh and theyre only $100 on ebay america.
cheers josh.

Not really, just buy it from U.S Ebay, most places will send here and with our $ atm it will still be a lot cheaper.

stavros68 · 16-01-2008, 10:17 PM

why are the mafs here so much??? quoted 450

Because they are rip offs here and the market for Windsors over in the US is HUGE!

b2tf · 16-01-2008, 10:42 PM

The 90mm SVT ones are easily got and I'm looking at getting one myself, if there are enough of us interested I may see if we can organise a few to come over at once.

xr8ute · 17-01-2008, 12:35 AM

If its for a stroker, then dont muck around....get the 90mm Lightning MAF.

What heads do you plan on running?

stavros68 · 20-01-2008, 11:36 AM

here is a pic of the motor with edelbrocks on it

rosco426 · 07-01-2009, 11:17 AM

To rehatch an old thread, need to get myself a new air flow meter for my XR8 (series 1) but still running stock injectors, everything really. Obviously the 90mm would be too big plus don't really want to waste money on an edit for the moment.

Would I still be better off buying from the states or from here and would sort of money should I be looking to spend?

Something like this?

Do you want a stock 70mm one or something bigger?

rosco426 · 07-01-2009, 11:34 AM

I would say stock for now. No mods are planned till well after others cars are finished.

Anything larger would require an edit and not really keen on spending extra money? What is an edit worth?

RG · 07-01-2009, 11:35 AM

About 1k for a custom tune, I'll be selling my 70mm MAF soonish along with my 24lb injectors if you are interested.

5.0 ED · 07-01-2009, 11:48 AM

Just to agree with xr8ute, my 70mm maf is pegged at around 180-190rwkw's.

dreadly · 07-01-2009, 11:55 AM

Austin id be up for a 90mm MAF ;)

Rosco, I think i read in another thread that you have an AU XR8 S1. Why do you need a new airflow meter, is yours broken? Not big enough?

The std AU V8 MAF is 70mm, and the one you listed has a different plug/connector for the electronics.

rosco426 · 07-01-2009, 01:08 PM

And broken it is. Comes up as a fault when plugged into the computer.

Different plugs you say, well that just sucks then. Don't want a bigger one or anything like that really. The standard Series 1 airflow meter would be enough. Don't want to waste money on edits and tunes when the car is basically stock and have plans for the future.

Would I be able to find a airlow meter to suit my needs from the states?

LowEL2XR8 · 07-01-2009, 01:17 PM

FTG sell the T3 series MAFs. They are strokers so it it is well equiped for future mods.
I think they are down to their last few so get in quick.

xr8ute · 07-01-2009, 02:02 PM

Do the FTG T3 MAFs include the electronics, or are they just the 80mm housings?

Rosco, an original AU V8 MAF is by far your best option. Have you called any wreckers yet? FTG would be worth a go if you haven't called them yet.

I am sure there would be a few E-Series guys interested in buying the 70mm housing from your dud MAF (to use with their 55mm sensor/electronics).

rosco426 · 07-01-2009, 02:26 PM

Thanks for that, just wanted to see if any from the states that were 70mm would do the job. Last thing I want is different size MAF and injectors but was an option. I'll ring around and see what I can find. Thanks.

philstoj · 08-01-2009, 01:28 AM

I might have a spare maf electronics to suit an AU V8 floating around, ill have a look and let you know tommorrow, will be much cheaper than buying another maf.

That'll be great, thanks.
