What MAFS is better?

I've seen a couple of MAFS swaps for Nissans: Skyline, Z32, and JWT's Cobra(mustang?). Every body in japan and alot of others use the Z32 so i assume its better than the skyline's MAF. Why does JWT use the cobra MAF, is it alot bigger diameter than the Z32 or is it easier to install, can it even deal with boost, what kind of prices am i looking at for each of these sensors?

Hmm, we don't use Cobra MAFS over here because we don't have any. The Z32's MAF has a better range then the Skyline.

Doesn't Stillen make there own MAFs. I would use a product by over a Ford or JWT.

Actually, I'd go with a stand alone to get rid of the MAF entirely. They suck as far as I'm concerned.

I'm with you there WD....the best MAF to use is NONE. They're not big fans of boost.

The Cobra MAF's are cheap and can read high amounts of airflow.

As far as MAP vs MAF, each has advantages and disadvantages. Just to name a few. Both have limitations. MAF's tend to be more restrictive (even if only slightly). MAP sensors can't account for a change in volumetric efficiencies since it reads only pressure and not how much air. It has to calculate airflow based on pressure and a known value for VE. From a tuning standpoint though, a MAP sensor is fine, since you will be making adjustments to account for the change in VE.

it also regulates by temperature, I think that's what makes up for the volumetric efficiency you'r talking about.
