If I do it im probably going to do it with a stock honda mnifold, it doenst l;ook quite as good as a blox/skunk2/edelbrock or w/e but theyre still pretty damn good. plus i could pick one up locally for peanuts

The OBX knock-off is $20 cheaper than the other knock-off:
OBX Intake Manifold 90-94-01 Integra GS LS RS B18B FMF2 - Integra Engine Performance
OBX Intake Manifold 90-94-01 Integra GS LS RS B18B FMF2 - Integra Engine Performance

I think thsi would be cool, and give a little soemthing to play with on the dyno:
Acura Integra GSR (B18C1) Intake manifold
It has secondary runners that are opened by a set of butterfly valves.
I think this manifold is the reason why so many ppl think that VICS works this way.

I thought you asked what the volume was...(notice I edited it after some scaling in AutoCAD), now => 1.82L
Compare that volume to the swept volume of the motor, and it's almost exactly 100%. Add in the volume of one of those 8" long runners and you're pretty close to the accepted ideal norm for turbocharged applications...150%. I had overlooked that you are supposed to use the plenum volume AND the volume of one runner for that rule of thumb.

I know plenum and runners are both there own science and thought they where calculated separately I need to know because I'm drawing mine up right now and this would change things.

I always thought you calculated the volume of the plenum without the volume of the runners? I know plenum and runners are both there own science and thought they where calculated separately I need to know because I'm drawing mine up right now and this would change things.

Read second page, middle paragraph.
Even then, a nearly 2L intake manifold plenum is much better than what we've got. Anyone ever measure a stock 1.6L mani, or is that what I'm doing tonight?

[QUOTE=gospeed81;511407]I always did too...but I found some engineering forum post earlier that said to include (1) runner...at least for the 150% engine displacement guideline.
This article doesn't mention it though:

Read second page, middle paragraph.
I couldn't find it but Ill dig out my notes on Saturday from my class on intake manifolds and see if its in my notes somewhere but I sewer the runners don't count for plenum volume in the calculation, however It has been about 5 years since I took that class.

I don't take MEEN410 until next semester (Internal Combustion Engine Tech. Elective).
Take it with a grain of salt. It was on a technical forum I use for drafting pointers at work. I've never heard runner volume considered either.
I spoiled my wife last night and didn't go out to the garage...so I'll have to measure the stocker this weekend.

I am getting a stocker from wanecur any day now so I can do it then. Im not trying to argue about the volume I just want to build mine correctly and make sure everyone else gets the right information. There is already some good information on this tread for some one looking to build there own manifold maybe it should be a sticky? Anyways I will be out in the garage tomorrow and will dig up my notes and post them up.
