Measuring what? Are you trying to get a turbo size out of this, or do you want to know how much air a D16Z6 can flow?

The latter is an easy calculation.

I wanted to know how much Air a D16Z6 needs when it is maxed out. I gues you could say it is kinda for a turbo/supercharging aplication.....

I've never seen flow numbers for a d16 head.

Neither does the lack of any details for your question.

1.6 liters at 6000 rpm is about 170 cubic feet per minute.

That's without any kind of pumping efficiency or port flow losses, just displacement, so it's an upper limit.

For FI, you'll use your boost pressure, but remember it's adiabatic compression, so it's not a simple ratio. An intercooler is another story...

So if I got somthing that could move about 10,000 CFM of air, is hooked to a TPS (throttle positioning Sensor) to adjust the airflow at different RPM, would that increase my HP by much? Also the air temp will be aprox. 40-70 Deg. F.

I think pressure differential comes into play here, what's that called "headless" ?

I hope you aren't talking about a leaf blower.
