So everything is taking longer than expected, so i decided to mock up a manifold design which had been engineered...
I built it out of cardboard, so its not that precise but you get the general picture.. What do u think of it??
The top and bottom are angled to direct airflow. In addition to the rear round pressure bulb.
The circles on the side indicate where the runners will go.. 1 and 3 on one bank and 2 and 4 on the other, as you can see they are not paralell to eachother. This is to prevent air scavenging from the opposite bank..
The sides are square to ensure that the velocity stacks sit flush against the side.
