Just wondering if anyone knows of a schedule titanium turbo manifold being made?

weiRtech

schedule? i imagine that'd be pretty hard to find material for.

^x2

I don't even think there would be a need to make it out of pipe in the first place. Not with Ti.

LS_teg

for a turbo app.? w/GT40 weight and dual 44mm wastegates

Titanium is not the answer at all. Inconel is the real king in that realm. It would cost less and work better.

LS_teg

that posts more of an availability issue more than titanium, can someone prove me wrong?

weiRtech

i don't think you'll find either in pipe. tube yes, both are available. finding them, well both aren't easy. i know burns has inconel, if you want ti, i may be able to help you out. pm me with what size you are looking for.

There is still no need for it.
SS is used all the time for set ups like that. And set ups far bigger.
Most still do it on sch 10. Some, on sch40...

I see absolutely no real reason to go with some sort of exotic material. SS will do the job just fine.

The "Blowfish" uses ss for this. This was built by Troy Trepaneir.

and heres a pic I took


I see no reason for any other material than SS.

In case you think two manifolds holding one turbo has something to do with it.
Also built by Troy

This isn't about whether it would be sufficient for the application or not, its whether one has been built.

By the way, beautiful car, Troy's a good guy

weiRtech

i think it is pretty safe to say no one has ever made a schedule ti turbo manifold.

adam, i saw that car at performance world too. a shame it is all wrapped.

atutt

Sorry...

I thought you were talking about if would support the weight of all that. Hence the need for a TI manifold.

I've never met Troy... I really wish I could one day though. He's been a big inpiration for what I do. Has been since I was like 13.. (Wow... 10 years already?)


Speaking of which.. A little OT.
I bought a brand new $300 tripod for may camera. Bought it 2 hours before the show.

I left in front of the Blowfish for over and HOUR!!!
And no one took... I got to my car and realized it was missing... Ran back full tilt.
(Actually ran right passed you!)
Still sitting there right where I left it.

No, I don't see strength being an issue, obviously, I was just curious to whether any one has made one.

k24em2

No, because its a stupid idea.

Fabworx

Why is it stupid?

91jdmhatchback

Because a main reason for using titanium is for weight savings while retaining strength. this all goes out the window when you said "pipe".

951parts

do it, hit some forums fro free OEM exhaust from :ducati superbikes, cbr1000rr,

and bikes in that calibre. cut the mufflers off them and weld it up!

you're going to learn the hardway when the TI manifold costs an arm and a leg, the thin stuff that actually saves weight does'nt have the tensile strength tho hold the turbocharger up,

Fabworx

For something that has never been fabricated, you guys sure know a lot about it.

951parts

haha, i say do it.

next month when you can shove this manifold in their faces they will be worshipping you with stupid posts like "awesumz fabricatorz"


and next time someone asks about they will post stupid **** like "search itzzz been done b4"

hell you can probably sale the fckers for $2grand a piece

dave@passenger

You can get Ti in schedule fittings, I've welded schedule 5 and 10 Ti before, hastelloy and inconel are also available in schedule fittings.

LS_teg

Thanks, this is exactly the post I was looking for, a positive motivating one, I wouldn't have thought most of them would be negative one's.

For any and all that are wondering, the project is almost complete, I was again just seeing if there are any out there. Not looking for opinions. I will post pics of the project soon

dave@passenger

You are on hater tech dude, its full of inexperienced and opinionated ********, welcome

I almost built a Ti tubular manifold for a diesel truck, its what the customer really really wanted, but something came up and he couldn't pay for it. I'd really like to do some sch5 inconel manifolds.

HiProfile

Titanium for a given weight/thickness of steel isn't as strong - and that's at normal temps. Crank 1500F gas through it, and it will go all limp-dick or crack on you. Even EGT's at idle are enough to weaken it. It's used for exhaust because it can offer more strength and fracture resistance (vibrations/fatigue limit) than aluminum can.

In manifolds the real players will use exotic superalloty steels like inconel, or 321 stainless for a more cost effective route. They can be made thin enough to be light. Certain inconel alloys can retain nearly full strength even when they're red hot. Certain steels will melt before inconel will even loose strength. It's a main component in a nuclear sub's reactor for that, and other reasons. Another reason it works well in endurance engines is the constant high heat would normally cause corrosion/embrittlement issues in lesser alloys.

If you really want an exotic manifold, you wouldn't toy with titanium. The shop I used to work at had some Inconel forgings for those subs they had to machine. Each was worth more in SCRAP than an average house, yet would fit in a van...if it could handle 16,000lbs.

Fabworx

The main reason titanium is used is for it's strength/weight ratio, comparing it to steel is silly, why do you think it is used so widely through aerospace engines, because it weakens under 500deg heat, I think not, titanium under high levels of heat with the addition of heating and cooling has shown to be more crack resistant than it's state before the input of heat. In other words, the more it's used for an exhaust item, the stronger it gets. That testing was done by Gulfstream International about a year ago.

Don't get me wrong inconel is a superb alloy, but this manifold is for a show car, so the "wow" factor is priority, I have welded and machined both alloys, and you would be surprised to know how many people I have worked with in the performance car industry that have no clue what inconel is.

951parts

yeah but you also run the chance of having most people not know what titanium looks like.

i come from honda's.....most people who modify cars lack knowledge unless it was fed to them in an advertisement. hell most people won't belive my watch case and band are titanium (low grade) but it still is.

if it's for a show car i'd just use mild steel and wrap it. noone would know the wiser./

Are you baiting the scrap guys?
