Who here actually blows through the MAF??

How many of you turbo guys have blown through your MAF and what (if any) problems did you incurr(sp?)

Due to the bottlenecks of our MAF and TB I'm going to try blowing through the MAF so I can run 3"-2.5" reducer to the MAF, 2.5" -2.25" on the MAF and 2.25" from the MAF to the TB. This should provide the least amount of bottlenecks from the blower to the TB. My local speedshop said that blowing through the MAF on the 1992 turbo miata didn't work for them. I tried explaining they are slightly different cars a decade apart.

So who has actually blown through the MAF and what was your experience?

Also, Do any of you aftermarket boosted proteges have problems "maxing out" the stock MAF's voltage? How much cfm does it take to max this out? How do you get around this if it's a problem? I know Juan ran 20psi on his car with the Maf and didn't have any problems...

I have a big ass maf for sale that will take care of your problems.

matt, dana hit the MAF limit i know for sure. he had a thread about it.

I also believe that on Juan's car the MAF was there only to make the stock ecu happy, and that it really ran on a MAP sensor with the Haltech

buy it.... I'll let it go cheap.....

He designing a kit that he can easily produce. More fabrication per kit = bad.

OMG!!!
LC-32GD6U 32" monitor for $3799???? way over priced!!!


lol

a new/altered MAF is out of the question. I'm just looking for info on the stock MAF and what it controls. does the stock MAF control the ignition tables any?? Since I'm controlling all of my fuel with a standalone what would happen if I just ditched the MAF altogether?? I know it'll try to adjust the fuel (limp mode) but since it can't will it affect the timing in anyway??

How did Dana get around the MAF voltage? just put in a resistor? If I could put a resistor in the MAF clip then I could essentially do away with the MAF altogether.

 

[BlkZoomZoom]

yes it controls timing also

 

[Super Matty P]

does anyone know how much timing it pulls when it errors? If it's just a little I could do away with it all together...run with the reduced timing and have full fuel control under boost.

exactly. you are using the F10X on this kit and should not need to alter the MAF in any way

i'm just worried about the volume of air maxing out the 0-5V voltage of the MAF like on the MSP's hitting spark cut.
