is the vortech MAF good?

Foxfan88 · Aug 8, 2006

Everyone is bashing the C&L and you know how that goes. I found the 73mm MAF by vortech on summit. Its pretty cheap (122$ for 19# model)

are these a good MAF??

thanks!

I believe that the C&L and Vortech Maxflow MAS are one and the same.

pistonhead351 · Aug 8, 2006

its made by c&l, mine has vortech and C&L stamped on it. same thing.

Why not just get a 70mm cobra mass air meter if your trying to save money. Thats what I plan to get when I convert to mass air. Theres a few on ebay right now.

you get what you pay for...I wish i had stuck to that moto a long time ago...i wouldnt be re-doing stupid things now.

It is funny how C&L meters have a crappy reputation on the web, and I have never heard a bad report on Vortech meters
Everyone says that C&L meters are worthless in boost applications. But somehow Vortech uses the same part and it works perfectly
Just another reason for me to think that C&L meters are just fine

As far as the 70mm maf, I am still not convinced that this is the best alternative.
I know some guys here have done well with this conversion. I think how well that maf does with our stock a9* computers will vary on a car by car basis.
In order for it to work, the computer must take full advantage of its adaptive ability.
Depending on how the car is running before the 70mm cobra maf is installed, it may work great, or it may not.

It is worth a try, simply because it should be very cheap. However, if the car is still running rough after ~ 150 miles, give up on it completely, as any adaptation on the computers part would have occurred by this time.

You can NOT run the *93* Cobra MAF on a stock stang without a chip/tweecer or the 93 Cobra EEC.

BTW: There is NO SUCH THING as a "COBRA" MAF! That's like saying "Mustang V8". Yea???

The 93 Cobra MAF has a different curve than the other Fox MAFs. ALL 94/95 Mustang 5.0 MAFs are the same (Cobra or GT). The 94/95 MAFs are 70mm and with a 70mm adapter plate, it's a direct replacement for a Fox 5.0.

Thanks for the info, I found a good deal on a Pro M anyway.

In case the pro m things falls through, you seem to know more than I do about this stuff, so could you tell me anything or give me any advice about this one? http://cgi.ebay.com/ebaymotors/93-M...ryZ42604QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

False advertising...

Quote:
This auction for a Factory Ford 70mm Mass Air Meter for '89/'93 Mustangs. This air meter is identical to the 1993 Mustang Cobra 70mm air meter except this is calibrated for 19lb/hr fuel injectors. This is a bolt on performance part. Nice Shape, fully functional.
Un-Quote.

There is no such thing as a Ford MAF calibrated for an injector size.

Ford did not do it this way.
The MAF voltage output is related to airflow in the computer, this is setting is known as the MAF Transfer.
The injector settings are completely separate from the MAF settings.

Only aftermarket meters are "calibrated" to an injector size.
"calibrated" is a loose term here though.

To make that that meter work properly you would need the computer for that meter, and the appropriate injector for that stock computer and meter (regardless of what that add says the meter is cal'd for).

Alruight, thanks.

Foxfan88 · Aug 9, 2006

man i am almost afraid to ever swap mass airs now. My friend swapped from stock MAF and injectors to 24lbs and the chrome bullet MAF i think its a PRO M brand not sure. And it made his car run worse, he couldnt figure it out, and it was so bad, he swapped back to stock MAF and injectors.

My car runs fine with stock MAF but i am sure there is power to be had there. I want to get a bigger TB, but i dont see the point in that if the MAF is only 55 mm stock, wont get any more air.

Whats the best MAF for me to get, i am running 19lb injectors and dont plan to switch for a while. I was planning on a nice biiger MAF throat along with a bigger TB and i figured it would net a gain i could feel on the ass dyno.

Its just all confusing because i have heard lots of bad stories on MAF and injector swap. I havent myself seen a swap gone good yet. I have see the cars with different MAFs but who knows how they ran b4 the swap, could have been better.

FoxFan -
Keep in mind that everything on these forums are a "problem"
We don't hear about all the swaps that go well.

Just be careful about what you buy. The main thing is to get the parts combination right.

Computer
Injector size
MAF tube diameter
MAS sensor (the little black box)

All of these things need to be matched as a system. If one of them is out of balance with the others, then the engine will not be happy.

You have the right idea about upgrading the MAF and TB.
I remember feeling a difference when I did my MAF and TB on the original stock 302.
I think Stang&2Birds posted that a larger MAF alone is worth some HP?

QDRHRSE · Aug 10, 2006

The c & L is ok. I've used them for years....the Pro-M is better. The big difference is that the C & L tricks the stock maf electronics by switiching sampling tubes. A Pro-M is a programed unit.

well what exactly should i buy to get a good power boost. I am wanting to stick with my stock 19# injectors. My engine combo is pretty mild... ported e7s, tmoss stock lower and a B-cam, I think the stock injectors will be fine, but i dont want to be stuck with a stock diameter maf and TB, bigger there would be great.

If i just do a MAF change when still using stock injectors, a computer upgrade will be needed??

I am afraid to stray away from the stock stuff, as it runs fine and doesnt give me any problems. But i dont want to be stuck with stock stuff that will only choke me off big time, now and as mods increase.

I think most people would agree 19lbs are ok for your setup.

I have had good luck with a Pro-M MAF and 24lb injectors. Like vristang said, no one posts when they installed a new MAF and it worked great. Lots of guys are running aftermarket MAF's with no problem.

If you change your MAF and keep your stock injectors, you will not need a computer upgrade. For that matter, you wouldn't need a computer upgrade if you went to 24lbs either, as long as you bought a MAF calibrated for 24lbs.

vristang · Aug 11, 2006

JChalfan - well stated

Maybe another way to explain the situation is...

Ford calibrated the stock MAF to the computer
and
the Aftermarket calibrates the MAF to the injector size.

If you get an aftermarket MAF,
then make sure your specify your computer and injector size.

If you get a Ford MAF,
then you will need to change the tune in the computer.

It will be cheaper and easier to go to the aftermarket.
Any of the aftermarket MAF meters will work well for you.

From what I`ve read,the C&L is designed to work with the stock air box.(silencer deleted).
CAI kits with the bend before the meter screw things up apparently for the C&L.

Foxfan88 · Aug 12, 2006

so if a stuck with stock injectors, aftermarket maf it would be good. The MAF would know i have 19lbs and the computer would know i have 19lbs

If i went with 24lb, the MAF would know it was 24lb, but without a tune the computer would still think i have 19lbs right??

When i get the cash, i will try the vortech piece out, if it wont work well with my CAI then i will just modify it where my filter to where its in the engine bay.

Sometimes you just have to tinker with stuff and make it work.

vristang · Aug 12, 2006

For all the help I try to be on the subject of MAF's, I feel like I just muddy up the water for everyone.

If you buy an aftermarket MAF to use with 19lb injectors and your computer, then no other changes will need to be made. The aftermarket MAF will trick the computer into working with the greater than stock airflow.

If you buy an aftermarket MAF to use with 24lb injectors and your computer, then you will only need to purchase the 24lb injectors in addition to the MAF. The aftermarket MAF will trick the computer into working with the greater than stock air AND fuel flows.

Properly selecting an aftermarket MAF will involve specifying your computer and injector size to the MAF manufacturer.

vristang · Aug 12, 2006

I doubt you will have any issues with the C&L/vortech meter and a CAI.

If any problems occur try "clocking" the maf, to overcome any turbulence issues.
