here is an example of a V8 model.
let me first give a review of what Wave does. this has been directly quated from Ricardo Wave:

"WAVE is the market-leading ISO approved, 1D engine & gas dynamics simulation software package from Ricardo Software. It is used worldwide in industry sectors including passenger car, motorcycle, truck, locomotive, motor sport, marine and power generation. WAVE enables performance simulations to be carried out based on virtually any intake, combustion and exhaust system configuration, and includes a drivetrain model to allow complete vehicle simulation.

Applications

Engine Performance – Prediction and optimisation of the complete engine from intake to tailpipe
Acoustics and Noise – Design of intake and exhaust systems for improved noise reduction and sound quality
Combustion and Emissions – Advanced combustion models for all types of combustion systems and in-cylinder emissions prediction capabilities
Thermal Analysis – Prediction of combustion chamber and exhaust system component temperatures
Dynamic System Control – Coupled engine control and driveline simulation
WAVE-RT – Real time simulation for control algorithm development in the SiL and HiL environments
1D/3D CFD Co-Simulation – Coupled 1D/3D analysis of intake and exhaust geometry"

"Ricardo engine simulation software is used by the majority of the top F1 teams currently to optimise engine performance, fluid flow and valve train dynamics.
Application of this software is also supporting leading GT, prototype and sportscar teams internationally. In North American competition, Ricardo has provided engineering support to teams and suppliers in CART, IRL and NASCAR in areas including engine development, control systems and thermal management."

their web page also has a downloadable PDF file (the second link) which they describe the application of their software.

I'm looking for A, B, C, E
for both ports

BC

You mean the oval diameter of the S4 ports? Also how long they are from port surface to valve?

DR

This might help some. This is fairly close measurement of the S4 Port, basically the same as the 85-86, except oblong in the opposite direction.

Hope its close enough for your program.

The injector fills the small semicircel on the top, right?

DR said, "This is fairly close measurement..."

Really? Only to 1/10,000 of a millimeter?

;-)

DR

For the most part yes, add a 8.85mm circle in there for the injector tip.

DR

Meaning the person that measured it :-)

HI WALLY!!

BC

There is a radius at the edge of the injector divot if you were going to be exact. Its a round edge. There is a measurement that Ken made that has it in a drawing for the S3 port.

Thanks
this is great. how about the dept.
my drawing basically is showing port diameter "C" which you gave me.
Then the Height "B" from surface "C" to the split for the two valves.
Then E is the distance from the beginning of the split to the valve face.
and finally A is the diameter of the hole in the port for each valve.(this is not the diameter of the valve)
sorry I was not clear.

PorKen

These are the dims of the 85-86 gasket. The ports are a little smaller in places, depending on the casting.

PorKen --

Nice drawing. Here's a question. Should a stupid business undegrad like myself try to design an intake manifold, what software should I use to draw that thing and simulate the air flow?

Best,
Tuomo

namasgt

so is there any one who can please measure the port dept for me?

BC

Depth? From where to where. I have an engine with no intake manifold 10 feet away.

BC

BTW - in your screen print you have 10:1 as your CR. This is more like 9.3 or so in an S4
