I think this is gonna give it the best flow we can possibly get!
Dude, Am I crazy? I really don't thing the front of the core area is short enough to clear your hood! I'm scared.... Anyway here's the plenum shape I'm gonna try and roll...... It's about our only option
It's gonna keep the air speed up, instead of coming out of the awic and falling on its face, like a velocity stack, how the bell sucks the air from around the lip? That radius is gonna pull the air torward the runners, With the flat lip it would have made a lot of turbulence
Interesting manifold design. You are going to get killer velocity with it. It will crank out some good low end torque, but it may limit your top end a tad due to that lip from the AWIC to the stacks. You will have a low pressure turbulence zone in the bottom 30% of the stack. The stack will smooth some of it out, and the long runners will do some as well, so its not much of an issue. If its ported good then it wont be an issue at all. I know its a bit late in the build to suggest some aerodynamic improvements for flow and velocity, but if you want I can throw you some.
In for updates!
Will be having Forge Motorsport build me a custom radiator with integrate heat exchanger for the AWIC, as one nice drop in unit, so I can shift the Rad to the driverside to clear the plenum. Heat Exchanger will be on Passenger side.
Similar to this, but no Intercooler, instead a AWIC heat exchanger.
Considering all the research I have done on intake design, I wanted as much volume as I could get with the space given.
That was the goal, gain more volume, there have been some testing done on FSAE engines showing that plenum volume 3 to 5x engine displacement was still making more power as volume increased.
In my case, my engine is just an 8v but the caps gave me more volume, nuff said.
Back Half welded on, now we just have 1.8t IAT sensor provision, and vacuum ports to add, and if i'm lucky I can have Nub tap the TB flange, and bottom center of plenum for WAI ports.
Glad to see it near completed. Nothing better then when brainstorming and napkin drawings come true
when I saw the mock up, and the beginning stages I didn't know if this would ever be finished.
Someone tells me you are tapping the manifold for some direct port injection
