I just had my Cartek heads and cam installed and am expecting over 400rwhp. Since I will be getting dyno tuned by BV Performance soon, I wanted to know if I should get a larger Z06 MAF AND if so, what year? Or just leave what I have????

I already have ported my TB and smoothed out the lip/wall by the IAC.

Any help is appreciated and I will plan on buying it ASAP.

Thanks
Brad

 

I think the jury is still out on the 85mm MAF. If you went with an agresive H&C package and will be spinning high rpms, it might be worth trying, although I only expect a few HP. I'm going to try the SLP MAF (bought second hand) on my new set-up.

 

From what I've read during the maaaaaaaaaaaaany posts on this topic; the ported stock MAF is more than adequate to flow 400 rwhp <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

By ported do you mean removing the center aluminum divider? My MAF is descreened only. The rest of it is stock. I did a search, and found a lot about people having problems with aftermarket MAFs, but not a lot about how much a stock one can flow.
Thanks

check on WizKid's site; I think he has flow comparisons.

 

I think BV is a fan of the 85mm MAFs, did you ask Brian?

Dremel those aluminum dividers and MAFT or LS1Edit your chit dude <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Too many people complain about problems with aftermarket MAF's.

 

I talked to BV, and he said they seem to work. I have also talked to some shops and they are running a stock MAF on their stock cubes 10 sec car. This is a big half say yes, half say no.... I have however pretty much confirmed that strokers need a bigger MAF.

How is removing the center sections of the maf any different than buy in the replacement ends? Not being a smart azz, but isn't that just about all the replacement ends are? I can have that done to mine realy easy on a lathe. The electronics will still get a little goofed up by showing less air flow than actual because it will be flowing slower due to more area?????

I don't care about spending the money, just want to do it once and be done. Don't want problems. 1 or 2 hp is not worth it to me. 5 will be for the minimal cash.

Isn't a lot of the gains from a MAF due to leaning the car out? With proper tuning, a MAF should only help if it was a restriction in the flow. Yes?No??????

On our flowbench test a 85mm screened maf will easily handle a head/cam car with little pressure drop....and the screen makes for better part throttle tuning for the fbod. (I know the new zo6 deletes the screen <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> ) That's what I would use...removing the screen and more programming probably would show a little more hp on a Superstroker but not a head/cam setup.

 

The shop I use has had best results with stock/descreened. Otherewise people are too lean.
