MAF readings from a NA ZHP

[rkneeshaw]

I don't have any logs from when my car was NA, could someone do me a favor and take a look at some of your logs and tell me what the maximum Kg/hr you're seeing from your MAF on your 3L M54B30 at full throttle and at what intake temperature?

Thanks zhpizza, except I'm having trouble converting to a value that names sense. Seems 1362 cfm is something like 2700kg/h. I must be missing something. I'm expecting the NA m54b30 to flow somewhere around 650kg/h or so at peak, or something like that.

I think the conversion goes the other way so ~655

That's would make sense. I've been googling and I see reports of 630-642kg/h but no indication of the air temp those readings were taken.

This all helps and is close enough for what I need. My ts2 kit will flow up to the max reading of 1023kg/h on only the coldest days, so safe to say it's about 1.5-1.6x stock. That matches the horsepower output increase almost exactly.

I was reading this: http://www.onlineconversion.com/forum/forum_1060119733.htm I guess it doesn't but that's the only way it makes sense.
