[Shotimes] MAF connector question

[Ron Porter]

It's also as was mentioned. In the beginning (like in the mid '90s), the
options were the C&L 73mm with a Mustang sample tube (very few people seemed
to get them to run right), the Pro-M 77mm (best option, but very pricey at
that time), and the cheaper 80mm Mark VIII 80mm with an LPM.

Today, the Pro-M 77mm has dropped in price, and the 75mm is a drop-in. IMHO,
those are the two best options. If you already have an LPM for other
reasons, getting the 80mm Ford is OK, but I don't believe it's worth having
an LPM just to run the MAF.

I bought my car with a calibrated (by Pro-M) 80mm Ford MAF, and an 80mm MAF
and a couple of LPMs. I'm now running with the calibrated 80mm, and will
sell the 80mm and LPMs as I won't ever use them again.

Understandable Carl, but I'll revert back to my original thought...  I'm
making 300+ HP with a 73mm and a 65mm TB on my Stang.  I also can't see how
an 80mm would be able to sample the air more accurately than any other good
quality MAF.  Actually the larger ones tend to have driveability problems
because the air flowing past the sample tube at low RPM isn't moving fast
enough.  More volume = less air speed.  I'm not saying that if I put an 80mm
on my Stang I would gain little bit, but I feel that it wouldn't be anything
substantial.  So why deal with these the problems on an SHO if you can put a
73mm or 77mm on it, bolt on your stock sensor and go about your way?  I get
the feeling some people go over board with their SHOs.  I posted a message
on a Mustang list about the 80mm MAF on a SHO and I got a lot of chuckles.
These cars are expensive enough without having to send your oversized MAF to
some guy to have it calibrated correctly.  Just my 2 cents.
