Take a look and tell me what you guys think of my turbo exhaust manifold.

Notice the expansion chambers.

It looks wierd because I had to get cylinder 1 and 4 on the same side of the split of the flange.

All made in house!
Let me know what you guys think.

Enjoy!

 

thats a wicked basket 'o snakes I like the integrated flame "cone" in the collector area. looks big tho. could be clearance issues?

otherwise

 

No AC offcourse!

 

drool.......

 

Colin..

its a interesteding design... what your your design theory-purpose of creating it like that...

having the collector designed like a cyclone is very interesting, but it sorta looks like it might restrict the airflow to the other 2 cylinder..

was there any type of airflow anyalsis on the design done?

 

looks nice. definitely must have been a bundle of fun to make.

is that suppy's work?

i'm gonna have to stop by one of these days. finally have another boosted car again after the miserable h22a accord turbo failure.

 

Sup Paul ! Yup that's suppy's work!

You should see what's attached to the manifold. Turbonetics said that I wouldn't spool the turbo till 5k, however due to the manfold deisign we were able to spool it before then 5k

Where are the support brackets to the block? That header would crack in 1/4 mile track passes. Looks good, but it needs support expecially if somebody is going to run a 40mm tial on the side of that thing with a big *** t4.
EVIL

 

Support braces are on the manifold, however it was put on after taking the picture. Good eye though. :thumb

That was one of the concerns, that the wastegate might be too heavy so we put a suport brace on. I hope the 304 stainless holds up for daily driving.

 

colin, yeah, i'm definitely gonna have to stop by next week or the week after. i may just switch to this manifold. i'm running a kooks on the current car i have. need suppy to do some other things for me too.

i'm scared to even ask what trim turbo you're using.

get that beast on a dyno and post the plots.

 

Wow, looks pretty cool. Dont see anti-reversion on many turbo manifolds :D

Are there any concerns of cracking since its stainless steel? Even with support, the expansion of the tubing itself could crack it.

 

Oh please you and your little turbo Colin hehe. I don't think that manifold by Suppy is good. You should have him make another one for practice (perhaps for the h22a4 design). I would even be nice enough to have him mock it up on my car. Sound good?

 

that is fucked up

Hope it works out for you

 

Very funny young, dont be jealous that suppy made one for me and not you!
ahhahhaha

Your T-(way too small turbo) is no match for mines. lol

 

Sigh......damn that Suppy guy. No more pool for him. On a serious note though, what boost levels you looking for? I heard 40-50 last time I was there. I would love to see the dyno for that one. Jack's car coming along as well?

 

In designing this particular manifold, what we've decided to do was base everything on gas expansion theories - lower pressure, increase velocity. Basically, if you give the gas an opportunity to expand it's speed will increase accordingly. In the collector area we wanted to give it as much room as possible, we weren't too worried about volume cause we used a pretty large diameter pipe size. We haven't flowed it on a flow bench yet, but are planning to do that soon, to see if there are any design flaws we can improve on for the next design. I'll keep you informed of the progress we're making with it, so far so good though, it works perfectly with the oversized turbo we matched it up with.

 

That's one of the craziest manifolds I've seen... good job.

 

That thing is insane, keep us posted on how it performs once you install it.

 

Damn Colin that thing is sick. Is there anything Suppy can't do? See you guys in a few days for my clutch.

 

twisted metal

 

twisty

 

intersting

 

Just out of curiosity, why do you need 1 and 4 on the same side if the manifold isn't divided all the way to the flange. Why do you run a divided flange and turbine for that matter on a non divided manifold?

 

what makes that manifold any better then the old KOOKS, i mean the KOOKS is an old design but that looks like the pipe length is really close to being the same as the KOOKS. i know you guys know that manifold, and why did you step the manifold? i will have pics up of our new turbo manifold soon. what are you selling those for, like $500? also are they equal lenght?

I don't think Suppy wants to make any manifolds for people (especially not for $500). That was an in-house job for Colin. I doubt Suppy wants to make more of those things people unless you can coax him with some magic dust or something (one magic dust I know is about 12 Benjamins).
