What MAF for supercharger?

[fastf50rd]

I'm gonna be runnin' 8lbs of boost with 42# injectors. I have no idea what size or brand MAF i need to get though. Isn't there stubby ones for a supercharger? Thanks for the help.

A lot of us have Pro-m's, 77 or 80. The 77 is actually more than the 80 but that's because the 80 has a plastic housing, and the 77 has a metal one.

GOOD LUCK

So, you think that's the best one to go with? How are the plastic one's, do they hold up well? Is the metal one better?

I actually can't find a 77. Does anyone have a link, or know where to get it? Also what is the difference with the bullit ones? thanks guys.

Sorry for all the questions guys, i'm just trying to order this today. What is the difference between a regular and a blow through also?

In the ProM line the electronics are the same on the 77mm & 80mm mafs.

The plastic mafs have been around for quite some time and I have not seen anybody complain of probs due to the housing material.

ProM makes what they call a "shorty" style maf and it is smaller which makes it a good choice for blower & fender mounting installs due to limited space.

The ProM bullet is 75mm and is less expensive than the larger 77mm & 80mm mafs. The electronics are not as accurate on the bullet compaired to the larger mafs according to the tech guy at ProM.

Lots of folks run the bullet with no probs however.

The blow-thru mafs are usually used by the power adder guys.

I've been using a shorty 80mm ProM for a while and have had no probs.

Thanks for all the info man. I just ended up ordering the 75mm bullit, it was cheap, and i'm on a budget. It should work great though. Oh man, i can't wait till i bolt on this supercharger.

The 75mm bullet is a good MAF in my opinion, I haven't had any trouble at all with mine (but then again, I'm not boosting). The only thing I've heard of with the bullet ones is that you should avoid having a bend in the intake tube directly in front of the MAF. Probably affects other MAFs as well, but the bullet has a rep for it.

So if I have a fenderwell CAI I should get the shortened version?

If it runs ok and it fits in the fender ok I would not worry about it.

I don't really understand your response. I am looking to buy a new MAF and since I have a fenderwill CAI I want to make sure I don't need a shortened version to work correctly before I buy.

Sorry, I did not understand where you were coming from.

I don't think the shorter version works any differently than the regular sized one other than it is more suited for small areas like in the fender and blower applications.

If you are looking at the ProM 77 or 80 then I would go for the shorty version. Even though I have a shorty 80 it is still quite big and I would not want to try to fit a maf any larger than I did in my fender.
