With the stock injectors being 270cc and upgrading to 370 cc, you would need to make a 37% increase of area in the maf. 37% of 270 makes about 100 which is the amount of cc's added. I measured the stock maf to have diameter of 3 inches. This gave me an area of 7.065 inches squred. 7.065 inches squared is 63% of the area we wish to obtain. So the area we want is now 11.214 inches squared. I then found the diameter of this ideal area to be 3.75 inches.

So in conclusion 370 injectors with a 3.75 diameter hacked maf will balance out the pulsewidths correct? How does this setup idle? Sounds like it would work fine at WOT.

One more thing, I can't find a compressor map on the ct-26 to figure out how much cfm flows at 10psi. I'm guessing because it was a stock turbo.

Wow.... stock S14 MAF has an ID of 2.5". Stock S13 MAF is even smaller.... I'm running like a 2.6" MAF to "tune" it rich, while Orion on FA is running a 3" mild steel exhaust pipe as his MAF body. Both of us have beat on our setups and are both running strong after some initial troubles (not fuel related, though).
