Scooter Posted January 25, 2004 Share Posted January 25, 2004 Just curious, as titanium seems to be finding its way into various things for its strong yet lightweight qualities. I'd of thought they'd allow for quicker spooling, something that the larger steel ones struggle with and i can't think of any problems, bar cost...........

Wipeout Posted January 25, 2004 Share Posted January 25, 2004 And it's a bitch to work with cause it's tough stuff. Have a go at cutting some 60mm bar with a hacksaw, not fun. I guess the parts of a turbo are cast and I don't think this is easy to do using titanium, could be wrong though. Quote Link to comment Share on other sites More sharing options...

jagman Posted January 25, 2004 Share Posted January 25, 2004 cost is one problem,also not the easiest stuff to work with ,weld,use with other metals,embrittlement, etc ,turbine blades could be made but who wants to pay 10 grand for a turbo:( Quote Link to comment Share on other sites More sharing options...
Adam W Posted January 26, 2004 Share Posted January 26, 2004 I believe inconel does the same job much better. Quote Link to comment Share on other sites More sharing options...

jagman Posted January 26, 2004 Share Posted January 26, 2004 hi supe thanks for asking,progress is being made, brackets all finished now, got the 2 check valves now one for charger output, one for turbo out put, i have been in touch with a company called demag(german i think) who can supply me an elecro clutch which is about the right size/torque,and still maintain balance at14000 rpm and they can make me it in 12volt, they usually do 24volt, (i saw "mr deano" the other day -he lives about 2 miles from me and showed him my charger,he seemed impressed) ive still got to fit a second intercooler to the l/h side -im passing charger air via this one, and turbo air via both, im waiting on an adaptor to be made from an oval shape(charger output flange)to round (pipe work) , i intend to connect it all up using flexi silicon/kevlar hoses which are available,and can be used as hose lengths are all fairly short, ill stop now before i bore you too death you did ask Quote Link to comment Share on other sites More sharing options...
SkyJawa Posted January 26, 2004 Share Posted January 26, 2004 Not at all, sounds fascinating - way beyond what I could do, but I can follow the principle!!! Its a cracking idea, can't wait to see the results Keep up the good work Quote Link to comment Share on other sites More sharing options...

Paul Posted January 26, 2004 Share Posted January 26, 2004 We use both at work, inconel and titanium, both right b*stards to work with, titanium much worse though. Paul Quote Link to comment Share on other sites More sharing options...
Adam W Posted January 27, 2004 Share Posted January 27, 2004 I thought most turbine blades were made of inconel anyway . . . at least on my Garrett jobbie. What the hell are they then? Anythings gotta be better than the dried mud they use for jap specs . . . Quote Link to comment Share on other sites More sharing options...

Guest Terry S Posted January 27, 2004 Share Posted January 27, 2004 They are selling Iconel turbo's now, the rally boys use them as they last a bit longer when using anti-lag. Titanium, isn't there a heat issue using it hot side of the turbo? Also Garrett are now selling turbo's with an Aluminium compressor wheel.

Steve W2 Posted January 27, 2004 Share Posted January 27, 2004 Titanium is stronger and holds its physical properties for longer and at higher temps. than normal or most stainless steels. I personally like the sound of unobtanium;) Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted January 27, 2004 Share Posted January 27, 2004 If thats the case Steve, why no titanium headers or down pipes? I found this on a racing exhaust fabrication site "Titanium is not recommended for high temperature applications ( > 1600º sustained ) like high pressure turbocharger or rotary engine exhausts" Quote Link to comment Share on other sites More sharing options...
Steve W2 Posted January 27, 2004 Share Posted January 27, 2004 Terry, you could be right actually. We use Titanium for parts of our burner becuse it is light, strong and can take higher specific point loads than equivalent steels. However, I didn't realise we were talking about temps. of 1600 degrees plus! I thought car exhausts got to about max of 1100 when running high boost. The mechanical properties drop radically much above 1200-1300 degrees dependeant on the composition of the material, thickness etc. Quote Link to comment Share on other sites More sharing options...
