[Shotimes] Re: 76mm MAF with 19# injector calibration?

[Alan Fanning]

I don't want to make this sound like I'm harassing you, or dissing C&L,
because that's not my objective. What I'm trying to say is that the reason
one upgrades a MAF is (usually) to free up some of the horsepower lost due
to pressure drop thru a stock intake. Achieving proper A/F ratio with the
replacement MAF is necessary, but not sufficient, to achieving this end. You
still have to have lower pressure drop through the MAF for it to be an
improvement over the stock setup.

Now, I have no doubt that a C&L 76mm MAF will flow better than a Ford 55mm
MAF, but the comparison to a Pro-M MAF, for example, is not obvious.  Since
I, and others, are trying to build a database of info on aftermarket MAF's,
it would be handy to have comparable flow data rather than hp claims. As an
example of the latter, I was on the phone with Scott in the tech support
group at Pro-M yesterday. When he told me swapping out the stock 55mm MAF
for one of their 75mm Bullet's with cone filter would add 22 hp to a stock
SHO I just about fell out of my chair. We should be so lucky!

It's hard for me to imagine that anyone developing a new MAF sensor would
not test it on the flow bench at some point. This is standard procedure for
intake systems - hell, the 1-barrel carb on my F150 was flow tested before
and after it's recent rebuild.  If they haven't done this it's a little
puzzling as to why not.

By the way, without individual calibration of the MAF, there is also a
question as to how close the OEM electronics were set at the factory (or
whether it has changed by, say, the sensor being dropped on the floor).

PS What's the retail/street price on a new C&L 76mm MAF?
