Volumetric Efficiency
I am wondering if anyone has taken the time to measure and possibly even plot or chart the volumetric efficiency of the stock EG33? It will be very useful in designing an "ideal" turbo system. I am looking into possibly doing my thesis on a EG33TT, but it's not till next year, so I'm starting my research now to see how feasible it even is.

Thesis? might I ask what you are in school for? I am also looking to get a bangin' EG33TwinTurbo, a pure monster, an eater of all.

Re: Volumetric Efficiency
There's a ve plot in the fsm where they are talking about the iris valve. There is a plot of what it would be without the iris system and a plot of what it is with it.

Re: Volumetric Efficiency
The VE plot in the WSM, is using the engine as an air pump, not running.
It shows 98%. When it is running and the exhaust is working also, it reaches 110%. If you are going to Turbo it, you will lose the exhaust action, so the 98% is what you would work on as the trapped percentage. Harvey.
