very good post.
thanks tenblade.

this motivated me to register.
here is an intake i made:

backyard's intake

Don't laugh

it's just for fun!!!

I like the sound

 

Hmmm, that reminds me, Ben...I have some toys for you to play with

Keep in mind fellas, there is no intake solution or modification that will remove
heat soak.

 

I almost forgot about that. PM me with whatever info you have. Thanks

So, since the Darcy-Weisbach Equation describes head loss and it states:
hf=f*L/D*V^2/2g

where hf is the head loss due to friction, calculated from: a friction factor f, the ratio of the length to diameter of the pipe L/D, the velocity of the flow V, and the standard constant for acceleration due to gravity g.

 

Yeah,.....what he said.

 

Intake tuning use to be a mix of art and science, but computer simulation has taken most of the art out of the picture. I haven't kept up, but the basics don't seem to have changed much. Guess that's why we call them the "laws of physics."

Correct me if I am wrong - but the speed of the pressure wave is equal to the speed of sound at the temperature and pressure in the intake runner (I think). That number should not be too hard to come across (I'm not an aero engineer - chemical engineer). Then wouldn't one size the length of the runner so that the pressure wave went from the valve to the reversal and back to the valve when the valve opens again during the next combustion cycle?

I remember reading an article a million years ago about exhaust tuning. Wouldn't the same principles apply to intake tuning?
