some pics of the intake manifold and turbo manifold i am working on

[SDprotege]

just some teaser pics we'll see how the intake manifold does

 

[SDprotege]

some work on the head as well

I'm having a hard time visualizing the IM....am I assuming correctly that instead of using the split intake design you've just wleded on a big round plenum for it to feed into the primary runners?

'twere it me. I would get the intake manifold flange and just make some simple 4 short runners and a cannister to mount the TB onto. This is the style manifold I have on my turbo-pinto and it wokrs well on top end without much sacrifice on low-end.

Subscrizzle...

Looks good

 

[vindication]

hmm, interesting. why not use different runners, that would net more gain then the OEM ones?

i'm playing around with a few diff. things i'll have some good dyno #'s real soon

yea the motor must look stock from the outside , i don't need any problems with the cops

Is that something more or less "thrown together" (forgive the wording) or is there some sort of calculation behind it. All the same, very nice work. Keep us informed regarding the gains.

Side note: I'm envious of your welding skills (thumb).

Not bad, but from what I've researched (I've got my Manifold off right now getting ported and polished) that any more space within the manifold will reduce the air velocity to a point where power would be lost on the bottom end. Of course top end would benefit from having less resistance for the air, but the VICS does that for us. What is your reasoning behind the resonator? Where is it plumbed to inside the manifold?

nice welding

it will be running around 20 psi of boost so i wanted to try to get as much air in there

That's all well and good, but if you have too much volume inside the manifold, you won't have enough air velocity in the bottom end before you're on boost to have any increase. In fact, a stock P5 will probably beat you for the first 3-5 seconds before you're on boost. Just something to think about. Hopefully you're leaving VICS intact?

hahahaha i would like to see a stock P5 hang ..lol
