Flipside Customs Intake Mani (1.6L)
Just thought I would throw up a few pics to guage some interest as the first few are being completed. Pics are off of BracedEunos' car which is using a mustang TB. Cantact Welcome to Flipside

The opening for the TB sticks out in front of the engine a lot more than the stock one. I'm curious how much room there will be for the charge pipe that needs to immediately turn-down for the average intercooler routing. Does this thing mean that only over-the-rad IC setups are going to be engineer-able. Guys with larger-than-stock radiators are going to be especially pinched for space there. Just an observation.

Hey look at that, number 1 is starved number 4 is over charged and the ones in the middle are somewhere between that. Who wants to torch the number one cylinder? Brainiacs other ideas are about 10 times better then this, and corky's symmetrical flow unit is also an improvement.

Both pictures tell the same story. It’s the orientation of the inlet that makes the difference.
One way to safeguard against starvation is make the plenum huge, velocity goes way down, so you don't create the shear in any cylinder, but that has its problems because of throttle response.
The sophisticated way is redirect the angle so that plenum volume is low and you don't interrupt flow in any cylinders.
You can think of the velocity field in the entry ways of the ports as spheroidal. If you are far away the velocity vectors are all pointing exactly in. As you get closer and the velocity is higher the velocity field straightens out in some areas because its filing into the port. When you position the T/B in front of those spheroidal velocity fields it interferes with them and causes the port not to flow well. Notice how the number one port slamming air against the wall on the onside and rotating down, and nothing is getting in on the other side. That’s the effect I’m talking about.
So the first cylinder's ability to fill is really impeded, but the rest of the cylinders do ok. The higher the R.P.M. and flow the more the starvation effect.
