How much difference will a 85mm MAF make?

I have most of the bolt-ons(headers, pulley, free-mods,etc) and I am spraying a 125 wet shot. I have a lid and the smooth bellow, however, I am now wondering how much difference having a 85mm MAF and 85mm lid would make over my set-up. Is it worth the $ to swap. Thanks

I had abad experience with the 85mm maf on my old t/a, all it did was throw a ses code for low frequency or low voltage maf. I would spend my 180-300 bucks on something else, like an intake manifold, or exhaust.

Me too, I didn`t see any dyno differences between stock and 85mm.

Yeah, do some searches on here, I had one in the plan and from what I've read you gotta be making 500-600+ before the 85 mm maf helps any.

Thanks everyone. I have full exhaust underdrive pulley, slp flo-pac, and a nx nitrous system. I guess this is all the smaller things that I can do. I think my next step will be a torque converter.

I don't think it makes much of any differance unless you're running the 90/90 setup.

I have a 85mm on my sey-up. No problems with it so far. I have 90/90 all the way threw. Even my TNT ring is ported 90. I also have TS air lid 85mm. This was on my 346. Now its on my 408!

GM High Tech tested on a while back. It added 2.8hp and 2.7lb/ft over the stock MAF. It only picked up power at peak. The curve was basicly the same as the stock MAF.

In comparison on the same test a Meziere electric water pump picked up 4.0hp and 4.8lb/ft and it made more power everywhere especially under the curve.

Hope this helps.

I really appreciate all the info. Looks like a 85mm is not for me at this time. By the way, i forgot to mention that I have already ported my throttle body. One more question; I know where I can get aftermarket ends for the maf cheap. I know that I would have to recalibrate the MAF after I put them on, but will the aftermarket ends do any good? Thanks
