Stock Maf Limits

The Fast Intentions Intake tubes are indeed 2.5". They have run them past 650, and within safe limits. From what I have heard, they can take up to 750hp(theoretically) on

They have run them past 650, and within safe limits. From what I have heard, they can take up to 750hp(theoretically) on their particular kit, no doubt 700 is within sight. I daily drive north of 610 on 12.6psi. On a 2.5" intake tube.

Your mileage may vary, maybe it is based on the kit setup, but they have found the stock maf easily capable of 650 without a reason for concern!

That's aggressive as hell, even on E85. I like your style!

You sure they dont flare up to 3" at the MAF? Not sure how you could anymore air though this 2.5" it just wont happen. I would be curious to hear any feedback directly form specialty Z.

For me right at 10.5PSI my MAF voltage is around 4.60Volts getting very close to the 5 threshold and IMO at the limits of the sensor.

Maybe altitude is playing a role here. All I know is I am most defiantly maxing out my maf running over 11PSI.

Dare I mention that we are also using puny gt28rs turbos, 2.5" exhaust, and a stock block?

BUT yes, daily driving a 600+hp/550+ftlb 370z is an absolute BLAST

Back on track, my tubes are DEFINITELY NOT 3" at the maf, measured them today, outside diameter is quite a bit short of 3"...if that helps any! I dare not pull anything apart, I have no leaks, no concerns, again I will leave that to Tony/Seb unless it's a dire need type of stuation.
