I wonder who is doing the heads. Looks like we will see how far that split port can go with Uractchko involved.

Don at DCI has had them for maybe 3 years now!Tom

Must be a different intake..
In that thread Chris says he designed this fresh and hopes to have a sample casting soon. |

With the split port running all the way to plenum it makes me wonder if one side moves more air (high velocity) than the other side what happens when the two columns of air/fuel meet in the bowl and then into the chamber??

Since my old company offered a split port head in production, (and both runners were mirror images of each other), there was not higher velocity in one side vs the other side.
Also I have inspected Don's heads a few times and I believe they are not a true split port but a optimized pushrod enclosure (minimal flow loss) with his design. My last employer's old round ports heads and pushrod enclosure (even with the vane) was not optimized for flow by any means. I talked with several designers of that head when I worked there. The split port was a interesting project. Tom V.

Offenhauser used to make this Duel Port manifold for Pontiacs. One small high velocity side supposedly for low end and a lower velocity side that dumped into the head.
Don't think they were ever successful. |

Likely the same person that helped on the intake...John Marcella.
