8 stack
I will post up over a period as I cant give this time in one hit, the project is progressing so I will start now and keep adding.
I decided to make an 8 stack for my 96 cobra modular engine.
I didn’t want to buy one because that goes against the grain.
The engine I have has a split port design, in one port it has a second set of butterflies this has been programmed to come on at 4.500rpm, the factory turns it on at about 3.500rpm.
The job of fabricating the lower section was deemed as to time consuming for the minor benefits if any that I may have been able to get.
The injectors are in the secondary throttle plate and this was also a factor as I wanted to retain their location as well as the secondary butterflies.
I gave up looking for a factory manifold as it seemed impossible here in Aust.
But one came up on fleebay about a month ago so I’m into it.
The first pic is the factory manifold with the top hat and throttle body taken off, it exposés the runners inside the plenum.
I attacked it with an air hacksaw to get the majority out then set it up in the mill and machined out the remainder.
