NUBWORKS ABA LRI Intermanicooler AWIC build

[jettred3]

crazy...looks good :thumbupcam
like the air filter shield you are using

Engine internals came from you guys too, scat rods, ross slugs, eurospec flywheel etc

Problems, in Motorland....

Need 1 Scat H beam rod, new bearings, and gonna grab the crank out of my spare ABA in the basement.

There was no bearing whatsoever left on Rod#1...

[jettred3]

Rod#1 was pictured with cap on backwards, till I reoriented it....

Bearing tangs should be on same side...motor was not run with cap like that....

[jettred3]

On the line with BBM, hopefully Scat will sell just one rod.

[jettred3]

And BBM came through, new rod is on only 2 grams off.

Updates Turbo will be bottom mounted, may need to source a smaller wastegate.....

Mockup was done without the PTE 5557E it is 4bolt





















I need to source proper length oil lines, comments? Its starting to come together, update from Nub soon.

[jettred3]

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

Where'd all the posts go?

How does one get to injectors/fuel rail?

[jettred3]

From the bottom with manifold off the head

New Rod came today from SCAT.

Also orderd the TT 276 cam, with .114 lobes. and titanium retainers.

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!

I would to hear your thoughts this goes for everyone

Looks like it won't be to bad with a ball end allen....

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.

TT 276 cam, lightweight int. sprocket and titanium lifters came today!

Shaved 2.37 oz off the valvetrain.

[Scrubbs]

I really need to come up with a lo cost aluminium shear and brake, that unit from Forge is nice.

[jettred3]

Caps show up tomorrow, pics will tell the whole story.

End Caps went right were I wanted them to go, gained .25 liters of plenum volume.

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.

Make sense?

[rabbitchaser]

manifold is coming out awesome i really need to get a short runner from nubs, amazing work.

[jettred3]

[jettred3]

Manifold Entanks!!!

[jettred3]

Valve Cover in progress....



NubWorks

Filler plates and a valve cover.......... Here's the start! —


Coming along nicely.

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

Yep, that little birdy would be right.
