This is work in progress, it will be made out of Carbon Fiber.
Any opinions, critisism, help appreciated.

looks nice similar design to the wilsons manifolds

 

EXACTLY . . . and if you're making it outta CF I hope it doesnt share the same price tag. Good luck on it though

 

if you do make it a good price then ill probably get one

 

for a good price

 

Only thing I need to still find out is whether the plenum and runners are the correct sizes.

If it flows well how does $750 shipped to the US sound?

 

kinda looks like a toyota supra IM

 

The design is taken from the wilson, with a few changes. I have not seen the supra one you are talking about.

Maybe i can post some pics, it reminded me of it. I think that manifold looks awesome tho!

 

I have been able to work out that it should be most effective at 7000rpm-10500rpm. Maybe a bit high.

 

U sir have some kickass cad skills...

 

That's a expensive project. If you can sell a CF manifold for that cheap then to you.

 

what helmholtz resonance frequency did you decide to tune it to? I am interested in how close it would match our exhaust manifolds freqeuency.

 

that crazy zigzag where the plenum meets runners looks like its gonna create really bad vortexes, plenum volume in the 2,3 runner area is to large, what giggler pin did you use to calibrate with a 93-4 you shouldd stick with the 84v.1? IMO

oh yeah sorry to be a total ***, but if that is to scale that manifold will rest on my lap while driving.

 

yeah, I think the wobbler shaft is too close to the angle of the dangle. What the hell are u guys talking about? Am I the only dumbass reading this post who feels retarded now?

 

make it out of composite plastic! it will be cost efficient and will help with heatsoak.

 

what program is that?

 

Geoff I will get back to you on that, I am not 100% sure yet my calcs are accurate(New territorry, and waiting for Jeff to help me out), and there are a few changes that will happen fairly soon.

rtype11, I will look into your suggestions,but it will fit though, of course im still playing with it.

vtec.dc2 the problem with plastics are that you will need to make a few thousand units as the tooling will be super expensive. CF also helps with heatsoak.

Alchemist I use Solid Edge V15.

that **** is funny

it looks cool

it dose look like a supra intake manifold that i have seen

From this picture the top cylinder will run lean with that runner being so flush with the very end of the velocity path. You need to stagger them in a stepped pattern where the first one the air will come into contact with when it enters the plenum is the longest with that design. Unless, you start playing with runner diameters. Changing the runner diameters raises the cost factor, and you'd have to figure out the flow rates, and the exact diameter that will match them. That would be a nightmare trying to find middle ground.


I need to start proof-reading my typing.

I will be making some changes to the plenum soon, check this spot

 

Update. Still working on it.











BTW: Why DOES the wilson manifold make power? I have been grilled on why it should not make power, so far no explanation as to why it does.

 

One more update:

 

the bellhorns shrowded by the flat walls on the bottom and the sides is going to hurt flow and increase turbulance. If you are wanting to use a raised bellhorn design you will probably want to look into raising them off the floor of the plenum. The other option would be to sink the bellhorns into the plenum floor but then you will need to fix the sharp walls and corners in front of and on the sides of the bellhorn.
