Billet intake manifold

[waxhead]

When we designed the wax racing intake true bore manifold, we spent a lot of time in the cad development stage to make sure that the cross section stayed the same all the way through the entire length of the inlet tract. This was to keep the air speed in the manifold at a constant velocity to keep the mass of the air fuel moving. You do not want any dead spots in an inlet tract caused by changes in area. We also kept the entrance to the reed as small as possible, the last thing you need to do is to machine it out try and fit the reed opening. This creates a massive low-pressure area and the air/fuel mixture loses all its momentum. It makes no difference to flow to open it up like unless you are trying to promote flow backwards up the intake manifold when the reed closes and the column stalls. The air builds up behind it and then looks for a place to go. This means it heads back up the intake manifold, if you have a nicely blended intake to reed manifold it will do this with great ease. By keeping the tract exit small we make it harder for it to enter on reverse flow and thus keeps a higher on the reeds waiting for them to open again.
After thorough and rigorous testing from our riders we are 100% confident that this manifold has better throttle response than any intake manifold on the current market.
