Exhaust Flow Rate
Turbo Mini Forums

I poked around some old threads but I did not find any that directly talked about the exhaust flow rate. I was wondering if anyone had any idea what the exhaust flow rate was for their engine (without a turbo). Ideally I am trying to find it for a 1098...but I am assuming there is more of a chance of someone knowing what it is for a 1275 or 998.

I calculated it to be about 99 cfm at 6000 rpm.....just curious if I am in the ball park.

The mass flow rate through the exhaust is the same as the inlet as the combustion adds very little to the mass.

The volumetric flow depends on the pressure and temperature at the point where you measure it.

As it cools through the exhaust it slows down.

for a NA 1063 i get about 56-60 CFM @28'' depression for the exhaust at 6000rpm.

btw, that is demand (just what pipemax spits out)

That sir, is not rust, it is the progressive mass reduction system
