Can anyone out there build a Single Turbo Manifold for the FC chassis with a Flange for the GTB88. And does anyone have any pics of some 3 rotor single turbo exhaust manifolds?

 

RE Amemiya makes one

 

its cool, im getting RPM in AUS to make it

 

That's who I was going to suggest for you. I've been talking to Tim down there and he seems to have a lot of what we need. Let me know when you are getting ready to order stuff, maybe we can go in together and save on the 200 shipping charges

 

Lately a lot of good info about RPM has been coming up. So far, sounds great.

And Greg, how much are you looking at with a manifold from RPM?

 

$800 AUS not too bad, im goin gto oroder this week

 

Can I get the number or website to RPM I'm in need of a manifold for my T72

 

rpmpc@picknowl.com.au is his email addy

 

wow, thats a REALLY good price. Is it stainless?

 

I dont believe that they are made out of SS. Tim stated in an email to me that they are made out of "Steam Pipe"... I don't know what that is... Maybe it is SS , anyone know what Oz considers "steam pipe"?

 

Yea, the stainless manifolds are more, this is for the mild steel manifolds, I stay away from stainless simply becuase they crack to friggen much and there is a select few that acutally know how to weld stanless steel correctly. Its not that I dont trust them, I just like the mild steel with coating(whick i plan on doing)

 

Steam pipe is cheap and strong, it is fucken heavy !!!

A whole bag full of mandrel bends (each bend costs about $5.50Aus) and flanges to construct the manifold with WG pipe adn flange plate will cost no more than $200Aus including fasteners, then you just fabricate it yourself.

It is very old tech bit it is as reliable as a cast manifold with the benifit of being better flowing.

Inconel is the ultimate, if you wan this e-mail Racing Beat and they will make you one. Will be ALOT but you cannot buy better.

 

inconel? is that aussie talk, or is it a type of manifold?

 

it;s a type of material....

 

Thanks shinjuku

hmmm, ill give yahoo a try, but could anyone help explaining its pro's and con's and give me a little more info about it

 

Racing Beat Inconel Manifold for 900hp 20b
http://home.earthlink.net/~rotaryeng/rb3rotem.jpg
aren't the tubes (runners?) supposed to be all of equal length


and more pics of the RB 900hp engine
oooh, pretty
http://home.earthlink.net/~rotaryeng/rb3rot1.jpg
whats that up front? I think I've seen someone say what it was before but that was a while ago.
the black and red looks like a dry sump oil pump, but it looks like someone ghettorigged a turbine to the e-shaft, but i don't know what for.....could that possibly be for the engine cooling (water passages)
That engine is incredible no matter what!


and another

and some info on inconel from http://www.rapidparts.com/rapidapr/turb.html




atkins sold a $15k plane setup including a inconel exhaust mani and Turbonetics T-S04
Inconel turbocharger. Does that mean the hot side was made of inconel or was it something else?




And I found that APR makes inconel exhaust manis, and i saw some kid who got a kit that included one to put on his audi a4 thats putting out 300hp, so it can't be too outrageous..hopefully




and lastly from dictionary.com

Inconel

n : (trademark) an nickel-base alloy with chromium and iron; used in gas-turbine blades

 

wow, that's nuts
that engine is sooo pretty
also that stuff is damn expensive
wow, that is a lot of money
sounds like really good material though

 

Peter, is a steam pipe manifold a good idea? I plan on making around 650 rwhp (hopefully) with my 20B, and I'm sure greg is gonna be near the 900 (maybe more, maybe less... who knows ) rwhp with his setup. Are these manifolds ok for our applications? How is it better flowing than a cast manifold... just simply because it is tubular?

I think an iconel manifold is a bit out of my league at this point

 

Yes, the tubes are supposed to be of equal length, and they are supposed to direct the air in the same direction, too. The manifold on my 20B isn't exactly correct, either, but if it doesn't cause surging, then I'm not going to worry about it.

Looks like a centrifugal supercharger.

It's probably made of something else, but I don't know. Inconel is a very common metal used to make turbine blades because of its ability to withstand extreme heat. It is very expensive and difficult to work with. I think that most people would be better off with a 321 SS manifold.

 

ha, thats another way of putting it, but why?
It is already turbocharged. I can only think of it as a system to pump/move something other than intake air for the engine, i wanna say coolant for the waterpassages, but would a turbo work if you pumped water through it? maybe its sealed to do that, oh well, its a mystery

 

Just to give you an idea about what inconel costs, think of it this way: inconel is an alloy that is about 3/4th nickel. Nickel sells for roughly the same cost as silver. So yeah, the material is expensive. One of the reasons inconel is popular is its properties allow for relatively thin wall tubing for the manifold, which also saves weight. Considering some of the turbos we'd like to run on the 20b's can weigh 30 pounds, I'd agree with Evil Aviator - 321SS is probably a better idea. The "common" sized inconel bends I've seen for sale are paper thin.

Personally, I plan to get my manifold done in 321SS. The last time I priced it out, 321SS was still about $45 per mandrel bend in 2" size, so it's still not "cheap". 321SS is awesome though, but it needs to be purged before welding. On a side note, I asked K2RD to cut me a 3-rotor exhaust manifold flange out of 3/8" 304 stainless steel. I didn't want to use the RB flange - it was mild steel and looked kind of shitty. I heard from Ted that it didn't fit right also. The K2RD flange is cherry though. They cut a few at the same time I ordered mine, so they probably have it in stock.

Here is a place you can buy Inconel piping and pipe bends. /www.burnsstainless.com/

thanks for the link immanuel
This place sells V-band clamps too

 

I'm having my manifold done by Chris Forsberg of lateshiftengineering.com out of SS for $7-800...don't know the exact price because we're also doing the turbo and wastegate in the total price.

I tried to get SR Motor to do it but I spent literally...months hounding them to do it and nothing ever got started so I looked elsewhere. I also tried Marcos Acousta out of TX but his engineer wouldn't do it unless they had the car there to look at. I'll badmouth Chris if it doesn't fit right from the dimensions I gave him...but the customer's always right
