Like it said how much power will a 75mm MAF handel before it pings? Im planing on geting a vortech SC or a Kenne Bell with in the next few months and was wundering if it will be able to handel it or will i need to get a bigger one, if it matters it is a Pro M.
Thanks

according to the ford racing catalog here is a rough idea

MAF Sensor Approximate max hp

55 mm (Stock 88-93 Mustang) 275 hp

70 mm (Stock 94-95 Mustang) 350 hp

80 mm (Stock Ford) 425 hp

90 mm (M-12579-54) 540 hp

5spd GT

Remember not to judge flow on the o.d. of the MAF sensor. The MAF has protrusions in it, some are big and some are small.

Pro-M rated there 80mm good up to 800 HP.

Just to put things in perspective for you.

good info to know

So a 75m should be good for what im looking to acomplish about 350 to 400 then.
Thanks for the info

It's not the size of the MAF that determins how much HP it can handle, it's the calibration.

The size becomes a factor in terms of airflow to the engine.

The 75mm will be just fine

my buddy is running a c&l 73mm maf and making 550 at the wheels on his 302. like said before just depends on how it is tuned and what kind of meter and stuff.

The calibration is all that matters, just check with pro m and find out from them because there will be a certain hp rating or air flow rating in which the meter pegs and as long as you do not go past that or have a throttle body bigger than your maf, you wont be hurting yoursetup, but i will tell you that with a kenne bell the less inlet restriction the better, and you will gain some horsepower going from a 75 to 90, how much im not sure because ive always had a 90 lmaf on my kb 94but there is a difference depending on the boost your running according to kenne bell.

actually larry i have a 80 mm c&l. pro m is bad about not making power. i had a pro m 77 and it was only good for 500rwhp before it pegged. a pro m 80 is only good for about 580 rwhp. the pro m 77 was for 36# and 80 was for 42#. we also have a 90 mm C&l for 60# and it has yet to peg at over 800 rwhp
