GOT MONEY!!!!
Hehe. I doubt many people have titanium parts on there car. I wouldnt unless i had nothing else better to spend my money on.

Re: anyone using titanium engine components? (yeah LS)
There's a certain someone I know who is using titanium valves. Supposedly different seats had to be installed in the head because titanium galls other metals. All I heard is the valves are like $79.00 each. Waaaay out of my budget.
Stick w/ ITR intake and 1mm over Ferrea exhaust, Mr.Dark Choc. lol lol

Re: anyone using titanium engine components? (Mike K)
dood mike...ive always wondered who the hell is that guy in the pic on your post??? is that your bf mr dark coco? i prefer mine light! hahahaa
btw, sema this year? ill be there.
okay back to the subject. i have a couple of titanium valves in my posesion i use as trophies. you know just siting around the room. omgosh they are light. as for using them, i would love to.
my dream motor:
roller rockers with vtec!
hollow cams
titanium valve components including valves and springs
b16a head
85mm pistons
b16b block
titanium rods
very light pistons like those seen in that previous post about the 355hp endyn motor
indy throttle bodys
bad *** header
and an ecu that has maps to 15k! hahahahahaah now thats a bad *** NA motor. anyone else have taht dream?
one day...one day

Re: anyone using titanium engine components? (yeah LS)
There seems to be somewhat of a debate over the durability of some Ti components.
The guy that built my motor has reservations about using them; even though it is very strong, they tend to get brittle and break.
Now whether this is due to poor machining, or the differences in heat transfer characteristics, vibration or something else, I do not know.
What we really need here is a metlurgist so that we can pick his mind....

Re: anyone using titanium engine components? (2fcknfst)
hey chocolate boy, i got that pic off the mullet website. http://www.mulletsgalore.com
yes, sema this year is a go. i am bringing the whole naples crew.
we'll all be getting lap dances, getting drunk on Heineken while you're sitting there having coffee talk with some stripper for like 2 hrs. HAHAHAHAHA
gimme a call dude,
later.
BTW, that motor you listed is what's going in my integra real soon. i am getting ready to test out the new hollow, prototype toda spec Z cams. 320 degrees duration and 25.4mm lift. custom pistons with extreme valve reliefs, triple duty titanium valve springs, and some other top secret ****. hehehehe

Re: anyone using titanium engine components? (2fcknfst)
TITANIUM:
Source:
Titanium is the fourth most abundant metal on the earth. It occurs in ores of rutile (a constituent in granite, gneiss, limestone, dolomite and some beach sands) and ilmenite (found in Australia, Canada and USA).
*** Introduction:
The technical use of titanium depends on its low specific gravity combined with (in comparison with other light metals) its high strength at room and moderately elevated temperatures, and its tenacious oxide film which resists corrosive environments.
*** Types of titanium alloys:
The properties of titanium and its alloys depends on their basic structure and the way in which this is manipulated during their mechanical and thermal treatments during manufacture. Four main type of titanium alloys have been developed.
Alpha phase alloys: usually contain alpha stabilizers and have the lowest strengths. However they are formable and weldable.
Alpha plus beta alloys: widely used for high strength applications and have moderate creep resistance.
Near alpha alloys: with medium strength but better creep resistance. Some are weldable.
Beta phase alloys: are usually metastable, formable as quenched and can be aged to the highest strengths but then lack ductility. Metastable beta alloys have some application as high strength fasteners.
*** Advantages:
-Low density and high strength to weight ratio, i.e. same strength but half density of mild and alloy steel.
-Low interstitial grades have excellent low temperature properties.
-Excellent retention of strength and creep resistance to 550-600 C.
- High fatigue and corrosion fatigue resistance.
-Transmits ultrasonic energy with little attenuation.
-Low thermal expansion between 0 and 500 C.
-Exceptional corrosion resistance, especially to oxidising agents, most chlorine gas, aqueous chlorides and dilute alkalis. Resistant to reducing agents if inhibited.
-Oxidation resistant to 550-600 C.
-Not normally susceptible to stress corrosion.
-Good resistance to cavitation erosion and crevice corrosion in sea-water. -Can be diffusion bonded simultaneously with superplastic forming.
Limitations:
-Low elastic modulus (105-125 GPa) compared to 150-210 GPa for steels.
-Sensitive to fretting corrosion.
-Low thermal conductivity (approx 5% of copper).
-Low electrical conductivity (approx 3% of copper).
-Attacked by reducing media unless passivated by inhibitors.
-Strong affinity for hydrogen (>130 C), nitrogen (>800 C) and oxygen (>700 C) which cause embrittlement.
-Stress corrosion can occur in some alloys by chlorides on stressed parts at high temperature.
-Crevice corrosion can occur at higher temperatures and if there is no cathodic protection.
-High cost of raw and semi-finished products:
(a) Expensive extraction of metal from ore.
(b) need to melt under vacuum.
(c) care needed to avoid embrittlement from air during hot working.
-Machinability, comparable to austenite stainless steel.
*** Applications of titanium and its alloys:
Aerospace Industry: Because of the strength/weight ratio and high temperature properties, it is used in airframe parts, sheet forgings and fasteners.
Gas turbine engines industry: Because of its strength/weight ratio and high temperature properties, it is used in compressor blades, discs, casings, ducts, engine cowlings, exhaust shrouds and heat shields.
Metal finishing industry (anodising, electroplating, 'Tufftride'): Because of its corrosion resistance and electrochemical properties, it is used in heat exchanger coils, mesh baskets, jigs, carriers and linings.
Chemical process industry(chlorine manufacture, fibre processing, acids and fertilizer products): Because of its resistance to wet chlorine and acids, it is used in pumps, valves and heat exchangers.
Metal refining industry (copper): Because the oxide film acts as a parting agent (reducing labor costs), it is used in cathodes.
Oil refining industry: Because of its corrosion resistance, it is used in making condenser tubes.
Sugar implants industry: Because of its compatibility with human environment, it is used to make hip, elbow joints, screws and plates.
Mechanical engineering industry: Because of its strength/weight ratio, it is used in crankshafts, connecting rods, torsion bares, cycle chassis, high speed rotating or reciprocating components.
Power generation industry: Because of its corrosion resistance to sea water, brackish water and brine, it is used for integrally finned heat exchangers tubes and steam condensers.
Desalination industry: Because of its good corrosion resistance to sea water and brines, it is used in heat exchangers for multi-stage flush distillation units.
Shoe manufacture industry: Because of its low damping capacity, it is used in making ultrasonic hammers.
Titanium and its alloys are also used for making jewellery, watch bezels and sculptures because of the decorative appearance of selectively anodized and colored surfaces.
*** Other characteristics:
Friction and wear: Titanium and its alloys are very prone to adhesive wear when in sliding contact with other metals and especially itself. This tendency to gall and smear onto mating surfaces is partly the cause of machining difficulties with titanium.
Fretting: Titanium and its alloys are susceptible to fretting. The reduction in fatigue life caused by fretting is the main danger.
Fabrication:
Casting:The high reactivity of molten titanium alloys with crucible and mould materials, combined with their high melting points, have caused considerable difficulties in the production of sound precision castings with un-contaminated surfaces.
Forging: Titanium alloys can be readily hot worked at temperatures generally somewhat lower than those used for steels. Sheet forming: Annealed and solution treated sheets can be pressed, stretch-formed, spun and dimpled but maximum deformation depends on the slow application of the load.
Welding: Titanium and many of its alloys can be joined by fusion, resistance, flash-butt and pressure welding, with adequate control of welding techniques. Techniques are governed by the metal's affinity for atmospheric gases and consequent embrittlement.
Brazing: Several conventional brazing techniques are applicable to titanium and its alloys; most experience has been gained with argon-arc, oxyacetylene, furnace and induction brazing.
Machining: The low elastic modulus (which results in spring back) and the tendency to gall and smear on to other metals makes machining difficult. To overcome these difficulties, the rigidity of the machine tool and work piece and the use of sharp tool s with good surface finish and large nose radius is essential. Titanium and its alloys can be turned , threaded, planed, milled, drilled, sawn and ground.
Powder metallurgy: The high cost of machining and the low yield of titanium in machined titanium parts makes the near-set shaping of complex components an attractive route.
