[Shotimes] MAF connector question

It is not an issue of size (diameter), it's the quality of the signal (the
tuning). IIRC, MAFs operate best at 80% or less of the rated airflow, and
the 55mm can push above that in stouter SHO motors.
Any of the Pro-M calibrated MAFs work well, and it doesn't matter if someone
gets a 75mm, a 77mm, or an 80mm.
Remember the TB is only 65mm anyway, and that is more than adequate except
for the most serious of blower motors.
All that said, a MAF is probably the LAST thing that anyone should spend
money on when they are doing bolt-on mods.

Thanks for the info Carl, I'll read up on that. I'm still an SHO noob. I
wonder though, why an 80mm MAF for a 3.2L or 3.0L 6 cyl? Guys run 9's on
80mm MAFs on a 5.0L revving to 7,000 rpm. Is it worth the hassle for
something that won't yield more performance then a 73mm or 77mm? What's the
most horse power someone is making with a SHO? I just can't imagine a need
for this application.
