Custom manifolds
 

Here are my new Intake and exhaust manifolds!
If anyone is interested I have a greddy and an HKS manifold for sale. They wouldn't fit with the turbo I am using.

Wow, that intake looks amazing, want to make me one?

Excellently fabricated!!

I'm a little perplexed as to why you went through all the trouble fabricating these manifolds without a little research done first. Perhaps you just decided to be different? I'll clarify, the exhaust manifold, why not go with the tried true proven to spool quicker AND make more power fully divided manifold? Also, bends within 3" of the turbine entrance can hurt some of the dynamics within the turbine also. And for the beautiful intake, there’s been a lot of research showing that having the inlet to each runner being flush with one wall or more within the plenum makes better torque and horse power overall then the velocity stacks being placed inside the plenums. Your still supposed to use a velocity stack type entrance to the runner, just not have it protrude into the plenum. Not trying to burst your bubble, its very VERY well fabricated pieces and will yet show good numbers and should perform extrremely well I'm sure. Its just not 100% as optimal as one could get while going through the work of making custom parts.

Again, nice work and it should have some impressive numbers.

If I could have put that large of a turbo elswhere the design of the manifold would have been different but you do what you can with the space you got. But thanks for the compliments. We'll see in the end what the numbers really are.

I got it done at www.twinsturbo.com They can make anything you want.

Here is a dyno map of a car with the same style header on a different car, smaller turbo. Seems to work just fine to me.

Awesome manifold. Ever seen their twin turbo kit for the Supra? These guys sure know how to make equal length manifolds. Imagine if they did a similar set up for the FD.

dam looks awsome. good luck.

I like the fact that the 30+lb turbo is now at nearly the bottom of the chassis.....

Sweet :bigthumb:

That's awesome work. Love seeing new and custom stuff. Personally I am most thrilled about the o-rings used in the lower intake. Why has no one thought of this before?

I share the concerns regarding the length of the turbo runners, as well as the decision to merge them before the turbine housing. It's been fairly clearly demonstrated that keeping them divided will result in a massive increase in response.

If you were worried about fitting a large turbo, it's really not that much of a concern:

It's much higher then yours though.

Another area of concern might be the brace that is run between the turbo and engine. With so much stainless supporting the turbo, I'd worry about movement. You might find that the brace is causing cracks in the manifold and not preventing them. One reason I have elected to not run such a brace.

It appears that the turbo is "hanging" from the brace with a balljoint connection, allowing for thermal expansion movement while still providing support. I'm making a brace right now with two balljoints between the engine and brace, but I think the hanging turbo method would prolly work even better.

Who says we haven't ;) I think the setup will work just fine. I agree that the Vstacks should've been flush to the bottom on boost. It tends to be easier to tune.

How much did it cost you if you don't me asking?

Here is the turbo I'm using. Don't really know how much it is costing me yet. Haven't put all the numbers together.

I don't see an issue with that exhaust manifold at all. In fact it's very very nice. The bend before the turbo isn't that bad. The turbo itself is a pretty good restriction and messes up flow anyways. Luckily it gives back FAR more than it takes! That's actually one of the few really nicely designed manifolds I've seen here. Good job. Take a look at a Champ Car exhaust manifold setup sometime. It looks an awful lot like that in design. There is even a bend right before the turbo but of course you also have to work within a small space in those cars. When it comes to turbos, you can actually mess up pretty badly and still get good results. You aren't going to see any issues with this setup.

let me offer my praises on the aesthetics of your setup. i'm at a bit of a loss on the technical advanatges (or drawbacks) of it. i can understand the protrusion of the velocity stacks not being necessary in the plenum, but the exhaust is where things start to get a bit over my head. i don't know enough to have a real opinion.

i used to know Eric (Grim) from when he was with Performance Factory back home in NY. i'm glad to see him and his brother doing such BIG things! as long as he hasn't changed since then, he knows his shit and i can say you're getting what he truly feels is the best - not just flash.

i expect to see great results when your car is done. one question though: what are you doing about your water pump. it seems that the turbo brace/anchor (weight relief) is attached to where one of the water pump mounts is.

where are you planning on putting the filter for the turbo? doesn't look as though there is much room from the angles in the pics.

Do you have a pic that shows the WG location?

To me his turbo looks like it uses an undivided turbine inlet .



If you look closely of the third pic above , you'll see a Miziere (?) EWP .

These are pics of the car that has the S366 on it.

The filter will be routed under the passenger headlight. It is tight but it will fit.

And yes it is a mezerie electric water pump.

Thanks diabolical1. Yeah grim and his brother are good friends of mine. They have put a lot into this car and I hope to get it done soon.

Thanks Rotarygod.

Nice ducting! It's also nice to finally see someone with a turbo get the air filter out of the damn heater of an engine bay. I don't know why more people don't do this? Contrary to popular belief the turbo is not making up for the less dense hot air so I'm clueless as to the logic. This may be the nicest setup I've seen on this forum yet. If it isn't, I can't remember what was done better. Bring it to Sevenstock in September. I'd love to see it in person.

Not too sure about that car but I am gonna try to finish my car by seven stock. And DRIVE it there. But unfortunately there is yet a lot of body work that needs to be done also. But I will definatly try to get Jack to bring his car.

Omg

Thanks for the extra pictures. Someone put a lot of time into that car...

Where are your oil coolers located ? excellent fabrication by the way ! I can see that a lot of thought and imagination and work has gone into your system ! It absolutely shows !!!!

im going to have to agree with rotarygod that exhaust manifold looks great. merging before the turbo will work better then merging at the turbo. and yes other people have thought of the Orings before i use them on a regular basis on intake manifolds and restricters :P.

Thats a really nice manifold is that your own 2-1 merge collector pipe?

I suspect that its a generic merge collector as can be purchased through companies such as Burns and such. It has a slight joint that was welded, yielding it a usesless slip joint, I suppose if its already there though, its easier then trying to butt weld it.

My first post here:

I am the guy responsible for the fab work on infinit1 and our road race RX7, driven by Jack Mardikian.

I'm glad you guys like the fab work I have done on these cars, so thanx for the nice comments.
I pour allot of energy into these projects, and most people cant see all the details, so thanx for noticing.

If anyone has any questions about the project, feel free to ask me, I will answer when I can.

and as far as the header /turbo / gate combo goes, this is a proven set-up, that works pretty well on our race car RX7. it is the fastest car in it's class NASA-SU here in Kalli, even faster than our supra..:confused: makes great TQ. and is pretty tough to beat on any Road race track, viper.. porsche..what ever. the RX does not discriminate...

any way just wanted to introduce my self and say Hi.

and some pics of the RX-7 race car are up on our site www.twinsturbo.com in the project car section.

oops, I said slight I ment slip joint D'oh!

really incredible fabrication on these cars, much props to you...

i am a little curious about the setup below:
http://www.twinsturbo.com/project_ca...s/IMG_2025.jpg

What is the function of this bracket and the lines running into it. (i am still kinda new to single setups) i have never seen this before.

It's a vacuum manifold.

very cool, thanks aaron.

looks like a great way to cleanup and manage the vaccum lines

What size downpipe are you running there?

the DP is 4" it transitions to a 5" oval and goes all the way back in 5" oval, transitions again to 5" round and vents to the atmosphere no muffler.

sucker is loud! loudest car we have ever built.

spot on, we have never built an FD before, this was our first attempt, glad you guys seem to like it.

can i get a "goddamn?"

Damn, awesome fab work. I've seen you guys on tv before with your Supra project.

infinit1 - your car is turning out great.

Both the manfiolds look great, I would love to have one. I recently saw the supras in super street, you guys do awsome work.

Hi , and welcome to the club ! Your work is top notch , I wouldn't mind trying something like it when I put together my next manifold ......., It wouldnt be the same , but I really like the LONG runner concept for the rotary ! , how long are they exactly ?

thanx for the compliments.

the runnres are pretty long...so long, that I fear posting the actual numbers,

I dont want start a "that will never work" debate.

How long?

I don't think anyone (including myself) was saying that it wouldn't work, just that it wasn't ideal. It's very rare to see a long runner turbo rotary manifold. Most people keep them short to maintain turbo response. Same with the use of divided housings. Probably not an issue for a car that is designed to operate at high load in the higher gears...

Awesome work so far...do you have a picture at another angle of the wastegate arrangement?

Aaron, dont be offended, I wasnt directing that comment twords you or anyone particular here..I just dont argue on the internet..too many "armchair experts" for my taste.

and we were trying to make TQ with the manafold design, turbo response is not a problem, we data log alot of stuff that helps us determine if the turbo is doing what is expected of it, and adjust accordingly, to suit the drivers needs...ETC.

Nice. I wonder how their twin turbo set up would look for the FD's.

those things have got to be close to the 3' mark - give or take. i'm rather intrigued. oh, and it really doesn't matter what you do, someone is still going to question, disagree or just flat-out try to discredit/undermine it -even if it's just to be a dick. so don't let that stop you from sharing anything you wish. let your craft or unfinished research stop you, but never one of the crabs that sometimes lurk around here. i think you'll find out quickly who the open-minded and/or scholars are - and they will always respect you, even if they have a different opinion.

if all else fails, i'm still a believer ...

Its a new "out of the box" approach that hasn't been widely tried yet ! so I doubt anyone can honestly say what it will do . On a side note , I saw a turbo kit on TV for a V8 that locates the turbo at the back of the car next to the gas tank ! the dyno sheet showed boost response very early in the range , somwhere around 2000 rpm !

Looks very nice...what kind of torque are you guys getting out of it? I would be interested in something like this if in fact it does improve the torque significantly

http://i15.tinypic.com/4ypftar.jpg

all most 400 LBS @ 5300
and 500 HP @ 8500 RPM

at 19 PSI, and it does this all day long, on a race track, sometimes but not often, it is inches from someones bumper, and it stays cool.

keeping this thing cool during a door to door race, has been challenging.

again this is the first RX7 that we have ever built, so I guess that makes me pretty FAR out of the box..
:)

Nice! But you need to load your company bitmap image there. ;)
