505 Intake Manifold COMPLETED!

headwork will play a factor as well. you can put freeflowing mani on there but if the head cant keep up it will be a bottleneck.

on a stock head, the gains will diminish at some point. its still going to be a huge improvement over stock. cant wait

well that's with anything....

anything is only as fast as its slowest component.

I know, i just dont want people who don't know to think just cause you slap on an intake and ramp up the boost, the skies the limit. You be surprised how fast the head becomes a bottleneck on this car.
 
lol sounds like a bunch of "he said she said" to me. My own feelings for Magnus and co. aside, Buschur needs to post up some proof if he wants such claims to be taken seriously by anyone other than his followers.

I will admit, seeing all of those pics of exploded manifolds makes me slightly concerned though. I will make sure to go over everything again with Skip and make any revisions needed to ensure that nothing similar happens with my mani.

Of course, a nitrous backfire would put an end to just about any aluminum intake, well designed and welded or not.

As a small update, I am confident that my latest design for the plenum bottom will be the end-all for all of the issues. Just need to go over it with the machine shop and see what they say about cost, but this will hopefully put it back on target price-wise. To do it the way I wanted to originally was going to put the cost into the 1k range, and we can't have that.

The only drawback is that this design revision will add some weight. I hope that everyone will be fine with it weighing a little more, performing better, and costing less. :)
 
Bueno, bonito Y barato. Escohe dos. I've always thought about this when chosng parts and modifying my cars. Good, pretty and cheap, you can only pick two.
 
my biggest concern would be dyno proven. hell if it still has the same gains of the 626 mani I would buy it. I have the 626 right now but I am waiting on this. I am probally going to sell it. I am just too lazy to take a pic of it. like all other crap I have sitting around collecting dust. also I dont think you would have to worry about nitrous backfire as I think everyone with an fsde is too scared to use it.

Is there going to be any kind of option for ITB's? I know that would require alot more modification of your current design but how sick would ITB's on this engine be? especially if it was turbocharged.
 
mazdaspeedwerx - It's going to be dyno tested.

MazdaSpeed626 - Uhm, ITB's are completely different. I can't even wrap my brain around how to do that on a turbo setup. This manifold will have individual velocity stacks, if that is what you are trying to say.
 
Actually I think the saying goes Fast, Cheap and Reliable, and you can only have two. But you were close enough.

Well I've always heard it in spanish and it rarely applied to cars. In cars it does go that way. I just like how it sounds in spanish.
 
Got a fellow local board member on board with the project. Kelly, aka crazybassmp5, is going to help get me back on track here with some machining expertise. Hoping we can "borrow" his shop this coming weekend and crank out the plenum floor. Everything else is ready to go.

So close now.

The Nissan RB26DETT uses ITB's....The ITB's on a turbo setup would be routed into a single plenum where the charge pipe would attach. But i understand, it is completely diffferent in design and probably would be way harder to make than i thought.

Yeah after giving it a little thought earlier, I was thinking that it could be done like that, but couldn't really see the point in doing so. Can't be much gains there vs a well designed SMIM on a boosted setup.

Didn't know that about the nissan, learn something new every day, haha.
