Intake manifolds
I'm doing some upgrading of my intake and thought I'd share some pics of the O/H.

I have it mounted on the throttle body, but it's not being used. The IAC feature is turned off in the EMS software.

I'm o-ringing some sealing surfaces, adding some additional fasteners to get ready for higher boost numbers (over 30 psi), changing materials of the fuel rails from anodized aluminum and plastic to stainless, fabbing an air bleed valve for the internal fuel rail, and whatever else that comes to mind.

Last defense poppet valve
I developed this poppet valve to guard against intake manifold backfires. It's common to see alcohol and/or nitrous cars turn their intakes to shrapnel. This device has saved me countless times throughout the years.
The design is pretty unique. Not the easiest way to make a poppet, but this design keeps the package short.

A sandwiching support plate on the outside of the plenum to make for a better seal between the plenum and the runner entrance plates. I use a Motoseal sealer on the mating surface of the runner entrance plate to the plenum.

A closer view of the runner entrance support plate. The notches in the support plate are to clear the electronic injector bosses.

So, what do you think so far? Gots to be the hardest way to make an intake manifold, right?
The next step is to machine some oring grooves on both sides of the runner legs. I was using Motoseal at those mating surfaces and only 2 bolts to hold it all together. As you can see in the last pictures, each runner leg now has 4 bolts and will use viton material rubber orings for a better fail safe seal. Orings are also used to seal the throttle body, the poppet valve and the plenum cover to the plenum. You can see the oring groove for the plenum cover in post number 18.

I thought I'd explain how I came to some of the decisions I came to with this intake.
The throttle body and the upper plenum cover. If you study F1 at all, you've noticed how they mounted that large air filter directly over the runner entrances and how the scoop diffuses flow velocity ahead of the filter. What an excellent design! They've found a way to effectively filter the air to save the rings and also use the filter as an excellent diffuser of flow pressure pockets ahead of the intake runners. A beautiful way to make sure one runner isn't getting a higher pressure than the rest. The shape of the air scoop leading to the filter is shaped to decrease flow velocity as it nears the filter. Again, this is used to lessen the chance of high pressure pockets before the filter. The whole system aims to provide equal flow at equal pressure to each runner. I tried to follow that same idea with my upper intake. The larger throttle body allows for a slower flow velocity entering the intake which lessens the chance of building high pressure pockets within the plenum. The upper plenum cover also is shaped to diffuse the flow velocity as it reaches the main plenum body. This alone does not guarantee equal flow and pressures to each runner. During testing it was found that the rear runners received more than a fair share of the flow. I somewhat fixed that by installing a simple spoiler in the plenum cover. The spoiler simply disrupts the flow aimed at the rear section of the plenum and creates a backup of flow or a more chaotic flow directing it more towards the middle of the plenum.

The port entry style is an eliptical flare as I stated earlier. Studies showed that this was the best shape to use in terms of total port flow. Even beating out a bellmouth shape!
I dropped the floor of the intake plenum away from the floor of the intake runners to insure that nothing interfered with flow into the port entries, from all directions. This design creates the problem of fluid accumulation in the floor of the plenum.

If you study post #1 you will see a small blue angled AN fitting at the bottom, rear of the plenum. In post #18 you will see a very small orifice in the bottom of the plenum below the large AN fitting. When in the car, a hose is connected to the small AN fitting and leads down to the left front fender well, where it is plugged. Future plans are to make a small collection tank with a drain petcock.

The drain is actually a very good tool for detecting whether or not the liquid intercooler is leaking. Yes, I've found that out personally.

Holy cow Don. That thing looks like a piece of a rocket launcher. Wow that thing is really big.

![]() If I can remember, I'll post a picture of the special throttle linkage attachment I developed to slow the throttle opening at light throttle positions for better control during burnouts, but increase throttle opening speed to normal at the higher throttle opening percentages. With a big throttle plate diameter, you end up having a very sensitive throttle. With normal throttle arm lengths, just a slight increase of throttle off idle can mean a lot of air intake for the engine, making careful control of the engine speed at light throttle openings impossible.

1) Make it any size you want with absolutely no consideration for tuning consequences. 2) Design it in a manner to try and take advantage of intake side pressure pulse tuning. 3) Design it in a manner to try and dampen, as much as possible, any pressure pulsing occurring inside the intake plenum. What are the advantages and disadvantages of each of these choices? Right now I'm concentrating on the intake plenum only. Intake runner dimensions are another story. Although, if you choose to size the plenum to take advantage of pressure pulse tuning, the intake runner dimensions must be calculated along with the plenum volume and configuration (single or split plenum) to arrive at a whole package that works together to optimized intake side tuning. The Helmholtz intake system is probably the most extreme example of intake side pressure pulse or resonance tuning.
