Do you all think that there will be any increase of power if I put a z32 MAF, vafc2, jwt chip? I want to know before I buy this z32 MAF from my friend. By the way I have CAI, Headers, and Fuel injector upgrade, wideband 02 sensor coupled with the vafc 2.

 

stock maf is good till about 300 hp, give or take. z32 maf is only necessary when boosting.

 

There is less restriction in the Z32 maf compared to the A32 maf.


As for the hp argument- Sure, there are stock parts that have been shown to support x amount of hp. But just because they can support a certain amount of hp doesn't mean that we won't benefit from larger and/or better flowing parts. That said, larger mafs aren't only necessary when boosting. For example, take a look at all of the n/a 5th gens running larger mafs.

 

We dont use the Z32 MAF because its larger but due to the fact that it is able to measure greater amounts of air that come in being FIed.
What others are doing is enlarging the actual MAF housing and transfering over the sensor to the new housing. Not sure if you will see a gain from doing so though.
The TB will also be a restricting point even with a ported MAF.

 

True, I should have mentioned that bit about the maf, but I got carried away.
