I am gonna try and make a lower intake to fit the SC roots blower to split port heads. The split port heads came ont he 99+ mustangs and 97+ F150's. The spilt port runner design netted 40 HP gain on the N/A V6 mustang motor. I have seen these heads net a 75 HP gain on a supercharged motor. So I am curious to see how they will affect power on the roots blown motor. I am basically gonna copy the original single port lower but have the end flanges have the openings for the split prt heads instead. Morana started one a year or two ago but never finished. I finally got some split port heads and intake to work with. Here are some pics.
The Fuel rail shoudl not be a problem as I will use the F150 rail reverse mounted. Just gotta get the blower high enough to clear it. I cut up the F150 intake to see what it looks like inside. The cooling channels are different, on the single port they run straight across the front of the lower intake, but on the spilt port heads they run down the center of the lower and across at teh front and back. On my intake I will just ahve it run across the front, as the rear opening are blocked by the gasket anyways and the coolant will just heat the intake anyways. If the stock SC lower has it just across the front then this one will be fine.
First I cut the flanges off the lower so I can use them as templates for making new ones.. After this I will make a lower plate for the intake, then fab up the cooling channels and then thermostat housing section, then the top level for hte blower to sit on and the rear opening for hte air to come in. Here are the pics.
Flanges cut off and intake split down the center

Thermostat housing removed
Center section split apart
