rather than have it polished, i chose to have it anodized which should provide better corrosion resistance than polishing.

 

how'd the motor respond to the new manifold?

 

aaron what kind of throttle body is going on there.... HUGE! haha

looks great

 

What machine are you using Aaron? Nice to see someone else apparently using a transformer, it makes me sad to see the tight little aluminium beads all the time from newer machines.

 

it is a wilson 90mm tb going on it. it isn't for my car.

machine is miller 180sd. maybe if i went with a thicker filler, i could probably get smaller overlapping on the welds because i wouldn't have to push it in so quick.

 

What size filler are you using?

 

same machine I use

 

filler is 5356. with a 6061 or 6063 base metal it provides the highest strength, best ductility and best color match after anodizing (which is apparent here). even the shop that anodized it was surprised. the head flange is darker though because it is probably a 3000 series grade aluminum.

 

Looks good man...nice.

 

Very nice manifold. If I had S2000, I would buy this manifold in a heartbeat.

 

Very nice manifold. I really like the Anodized look rather than polished. I may get with you for something soon. Keep an eye on your pm inbox.

 

sorry, i didn't answer the size of filler question... it is 1/16". i'll have to try maybe 3/32" or even 1/8" if i get a chance.

yeah, the anodizing was done locally, they do a lot of simple stuff, not too often they get welded stuff. this was a regular clear anodizing. they can do just about any color. they also do hard anodizing which is quite scratch resistant. they used to a lot of stuff for dirtbikes. one of the parts they hard anodized was for a trans cover that the rider's boot rubs on all the time and after a full season, all the anodizing was still intact.

 

Nice! The anodizing has a really nice finish to it.. I like the IACV plate too

 

very nice !!! where or how did you make the form ?

 

i like it.

 

I always thaught computing and flow test were involved when making intake manifolds but now that I see new manifolds pop right left and center I wonder... It all looks like a bunch of sheet metal welded together and given an intake manifold title... what's up with that?

No offense to the OP, I like what I see. I'm just wondering how can so many people come out with so many designs and all claim gains.

 

which part? the plenum halves were formed out of 1/8" flat using a 1" radius to bend them. the transition from the tb flange to the plenum was formed from the same flat using a slip roll, a piece of round stock and an arbor press. the next one i do, i'll do a writeup, but it won't be posted on here since every time i seem to post something it gets taken down or locked.

 

what program did you use to design it?

 

i originally drew up the design in wireframe so i could get a rough idea of the size i was after. i would have liked to have had a cfd test done on the design, but time and budget would have made the end product much more expensive for the consumer. also finding someone to do a cfd test hasn't been that easy, i did try, and would like to still have it tested.

i thoroughly researched other designs, chose the characteristics that i wanted to include, then added my own personal ideas that should help improve on what is already available out there for this application.

1. most any other manifold has a tapered plenum. only a handful seem to have a smooth transition into the plenum from the throttle body flange.

2. most sheet metal welded intakes have a flat plate at the floor of the plenum around the runner inlets. i feel this is a flaw in the design of most manifolds, and is a common failure on high boost setups. having a weld on a sharp corner is a very weak point when you begin to apply high pressure inside a vessel. idealy, a round plenum would be the strongest without any welds, but having the weld seam along a flat butt-joint on the plenum will allow it more flexability under higher boost pressures when there is a chance it can swell, rather than having a weld along a corner.

3. velocity stacks inside the plenum have been proven to be effective on many different boosted applications. i was first inspired by the carbon fiber velocity stacks that are inside the turbocharged 2.65L v8 xfe cosworth engines that were used in the champ car series.

4. tapered runners help provide an increase in air velocity as it travels down the runner and is a common design feature of aftermarket intakes and even some oem's.

5. anodizing the manifold will increase the corrossion resistance of the manifold which is important especially if more corrosive fuels are being used with the setup.

 

Want to build me a mani indentical to this for an f22a1? haha.

Except the throttle body flange would need to be on the opposite side, obviously.

 

funny you should ask that. i'm building that exact manifold for a local customer. question for you: what is the piece on the upper plenum near the mbc? the one on the left is the iacv, but i'm not sure about the one on the right.

 

If you are reffering to number 8 its the FITV. Which Im sure can be deleted... I could be wrong. You're probably used to seeing them on the bottom of throttle bodies.


Pm me about the intake manifold pricing. Im getting ready to do a top mount 35r setup on an f22 in prelude to be different. Looking for reputable places to do work for me. Plan on big things from this setup. Looking for all the help i can get.
