Bigger MAF....Is it worth it and do I need one??
Bigger MAF....Is it worth it and do I need one?? I am looking at getting a cam....I have other basic bolt ons and long tubes.....
Would I benefit from a larger MAF......

It depends on "the money". I'm running a $40 truck
MAF I got off eBay, with the screen popped out. It
works fine. Had to "tune" it (just wrote a stock truck
MAF table). Would I spend $199.95 or more, for some
hype? Hells no. If you're sticking with a stock TB /
intake then I'd find a junk MAF and pop its screen,
swap on the front end piece and be done with it,
keep your original screen just in case of whatever.

I would tell you that first you need a ported throttle body. After that I got a fast times 85mm lid. I also got a 85 truck maf. It is alot bigger. I ported it and got rid of the screen. At the time I did it I just the lid and MAF. Cost 260.00. There was higher Manfold pressure. So this was a restiction. Bottom line. Get cheap MAF bigger lid and tune. I did not have to pay for tuning. I saw gain.

The stock electronics will support 500rwhp is true, but it doesn't mean that a stock 78mm maf will hurt flow compared to a larger 85mm maf.
I hear that statement all the time, and you could say that the stock exhaust manifolds and exhaust will support 500rwhp as well, but that doesn't mean there isn't a gain to be made by swapping to something that flows better.
Swapping a maf to a larger unit is more about reducing the induction restriction to flow, just like going to headers or an offroad ypipe.
You may not see much of a gain, since the 78mm maf flows the same amount as your stock throttle body, but is a neccesary mod to do when you go with a larger throttle body or intake manifold.
You have to understand that there are two elements to a maf in terms of making power:
1. ability to flow a specific CFM
2. the electronics side of the equation.

Verdad Gallardo Well ok so i think i'll stay with stock maf since I bought it from GM last year...but what about the bigger MAF ends??? Are they worth the 60-70 dollars that they sell for???? I wanna buy the Fast toys 85mm lid thats why I was considering the bigger MAF....but maybe just going with the bigger maf ends would be ok??....
I still have the stock 78mm MAF on my car and make over 500 rwhp. Im sure there are some gains to be made with a bigger one, but there are better places to spend the cash to make my setup better.

Does anyone know the the cross section area of a stock maf? I do. Why do people always rave about the performance increase of bigger throttle bodies and cold air, but the same ol' maf is fine to 500hp. I beleive the Maf will work on a 500hp engine, but my factory radial tires also work on my 600 plus horse 5000k convertor car. Work and optimal are different. Get what I am saying?

What if you suspect your MAF is bad and you need to buy a new one anyway. Is it worth getting a bigger unit like a SLP MAF at that point or is the stocker still the way to go?
