That is very nice and very clean, top work dude.

Sometimes manifolds like that have dividers to ------ the air around. If it doesn't though, then as you suggest is a real possibility. Of course, a good sequential ems can fix that with trims more or less. Best we don't get into discussions about subtle flow stuff here again though. The skyline manifolds are a very similar style and no one has problems in practice. The time between intake events allows some evening out to occur.

 

U sure that intake manifold is gonna be able to flow that much air? Just doesnt seem like a very good design for that amount of HP. I would figure smaller runners with larger chamber. Ive chopped my e36 m3 apart and its pretty tiny in there. Ive seen lots of cars choke on the dyno from the intake manifold not being able to flow the air. What about the euro m3 e36 itbs. or even custom??

 

I SEE:

JB WELD!

Rock on man, great work.

 

Yes I am sure - it flows as much as aftermarket Schrick manifolds, the only problem is its ABS and not cast aluminum.

I will be going to a sheet metal aluminum manifold later, but only for strength.

Here is a comparison of the OBD2 manifold (left) and my OBD1 manifold (right):

 

Thanks to stenseltizm, I found the right fittings. I didn't know, but you can download Solidworks drawings from www.mcmaster.com

I also made the block a tad smaller.




I just noticed that my tubing sleeve is the wrong flare angle... ----!

 

I think its because you've got 37 deg AN fittings and a 45 deg flare sleeve. Fwiw the sleeve doesn't really seal on the face of the NPT fitting, the flared pipe does, but still, minor details.

Isn't SW easy? Once you figure it out its cake.

How did you download the parts from mcmaster

 

It's easy, once you browse to the exact part you want (down to the individual part # and size, not just the type of part) there is an option on the header to download. Once you click on that there is the option to download it in multiple formats, one of which is a solidworks file. When stenseltizm told me about it, it was like I struck gold! And yeah, solidworks is awesome, I've had it for a couple weeks and I already love it, definitely my favorite program.

So, what's left to do before this beast hits the streets? You figure out what you're gonna do for engine management?

 

Yeah I am going to run DTA S80 Pro with 1600cc injectors.

All thats left is getting the nitrous guys air tight (jb welds!) and I made a methanol block tonight but I messed it up tapping it

Here is what else I did:

 

wow, that comp housing is

 

just because it can flow as much as shrick doesnt mean it can flow enough to make 800 - 1200HP. Those intakes were both designed to create the most hp/tq for a NA setups. Fine me another 2.5L engine with 800+ hp that uses long runners and a small chamber for their intake manifolds. Gonna be hard pressed. Long runners are designed for low-mid range tq. Dont be supprised if you find your limit at your manifold. If i were you id ask around, but i believe to make the numbers your looking for your gonna have to go 1 off custom with shorter runners and alot bigger chamber.
