I can get you one easy. It'll be laser cut...how thick do you want it?

 

I will make a flowbench once I actually need one Right now everything is done from Fluent, SolidWorks and FloWorks.

As far as an intake flange for the Evos you need to make sure you can get the angle correct for the injectors (Or just machine / weld them after the base flange is cut).

Also, if you wanted to send me any files to crunch Id be happy to do so for ya. I could even modify them slightly if I see an easy area to make it better I have too much to do but I find it fun

I have decided to make at least a few sheetmetal intakes so Ill be designing a new one that will work with sheetmetal. The good part is I can design it in a way to get rid of any of the more common sheetmetal issues (Like exploding ).

 

what CAD/CAM program did you use to design that?

 

SolidWorks

 

Trinababe is my heeeeero :P

 

looks good

if you need a evo 9 to test over in california...let me know

lol

 

well, if you would like, I might be able to rapid prototype it if you want to share the file (not sure how protective you are of it) I can flow bench it with smoothed ports (the prototype machine leaves a rough surface to be filled with epoxy) and give you real world feedback.

I'd still like to see how your original design would work out. Wouldn't be too hard to make a mold and make a thick carbon plenum aluminum runner prototype.

I've been using helmholtz for my runner lengths and rules of thumb for plenum sizing. Using basic fluids and aero for plenum shape and flow though. Could do a test at the dyno shop using your plenum and some of my runner length values.
What ID (or area) do you use on the runners?

I'll have to finish modeling it mine up and send it to you as the cfd guy at the windtunnel is always busy and the rest of the me's and ae's I know refuse to run it. lol

I'm an Inventor guy but do have solidworks. I'll probably just convert the drawing.

 

What type of prototyping can you do? That is the most expensive part of the deal honestly. Turns out the problem is the actual dimensions of the model... if I broke it up into lots of smaller parts I could get the cost down but it would start to loose some of its functionality.

I started with the Helmholtz algorithm but figured out it really doesnt do all that much for forced induction but it did give me a good starting point.

The runner ID is not static... Not sure the actual total area of them but I could find out.

 

have two really...one is at the windtunnel, called a shop bot and cuts from foam...more like a large cnc mill really. Used this for FSAE intake manifolds before. Usually used for quick aero modeling though.

the second is a plastic rapid prototyping machine that would require making the manifold in several pieces...also a bit harder to get permission to use.

helmholtz really isn't better for na vs. forced induction...it still increases ve's at the tuned frequency. Its effects might not be as great though.

I would certainly hope that they aren't static and are tapered. The average runner area could be used...just the cross section at mid runner.

I'll have to hop on AIM sometime and talk about it with you.

 

Wow Nice Work

 

Awesome post.

 

nice setup thus far

 

Have you thought about selling the design to a big company (AEM/DC Sports, Injen,etc) to manufacture? I bet they would be willing to purchase it for a pretty penny, and you may be able to get some sponsorship for your dragster!!!

 

Any updates on this project?

 

Yes it would be even more informative to see the results of an actual real world test on this design.
