Dual plenum pics

Looks good. Nice to see other people trying out different things. I hope your intake manifold turns out nice. I'm currently building 2 manifolds. One with the velocity stacks above and another with thick walled stacks from www.rossmachineracing.com

I really like the thinner walled stacks much better then the thicker ones as flow into the stack is improved by the larger bell mouth. Once the flow has entered the stack, the tapper helps turn the flow into non turbelent, laminar flow. This makes the whole intake manifold perform better. I will compare the to intake manifolds and post the results. May be a bit out as I keep building more stuff that keeps the car from running.

One idea is to brace the plenum to the flange itself to help carry some of the load put on the runners by the throttle.

95% finished now, the last parts have been tacked together with the Mig and will be off to the welder this week to be Tigged. You can see here I have supported the plenum's (which together are a bit hefty) to the flange with a thick support bracket on either end. Not pretty but they should take the load off of those thin runners.

Once it is all done I'll pressure test it and if all ok, bolt it to the motor and try it out, I am looking forward too, to seeing how it performs with those nice tapered runners .

Cheers

Nice work Mark. I'm sure it will look good when it's finished. Lets hope there is a performance gain, after your efforts.

Niiiicceee , dyno would be just great .

nice do you have more pics?

[4WheelDrifter]

Yeah. C'mon Mark. More engine porn for us please. Or are you just going to tease us, and make us wait?

[volcano rs]

its coming along well . did you strengthen it from inside ?

Here are a few construction pics, thanks also to Jirki Repo who gave me some good advice and tips.

The smaller plenum

Lovely

Welded together

This is close to what it will look like once it is done. If it works out OK I will post the Project in the Projects section. If it falls apart I'll stay quiet and pretend it never happened...LOL

looking good. looking forward to se a picture when its mounted

have some belief in your self . why shouldn't it work ?

Don't worry Jamil, it was meant to be a joke
