WORLDS different between a thermite reaction and what you'll see in applications... really, worlds different.
You don't use any pure metal in a high stress environment, you use an alloy.
Forged and/or billet Ti rods aren't a bad way to go, I'd looooove those someday
Offtopicish time:
When you get aluminum bits down to a sufficiently fine size, you'd have enough actual Al to be useful in a rX. This in turn has the free Al particles able to react with the Fe and create the highly exothermic process given sufficient oxygen and initial energy (friction heat). I don't hear of Al engine parts spontaneously combusting a lot. There are turbochargers out there that have Aluminum compressors, and some jet engines as well (in the lower temp areas so it doesn't melt first)
I don't want to stray offtopic by posting rebuttals to the aluminum armor idea, it can get quite lengthy. However yes, ANY metal on fire is a real bitch to put out and I wouldn't want to be near it. And anything that has Aluminum armor, I wouldn't want to be in just because it's not exactly the toughest material out there for withstanding a lot of bullets or impacts. (RPG would probably punch through the Al armor getting the explosion to hit the inside)

People who are bashing titanium rods:
A) are too poor to ever afford a set, therefore must bash them to justify going with cheap ones
B) Don't understand metallurgy or the properties of titanium
I don't see how someone can bash a good set of titanium rods?!? They are expensive, but they are the best material for the job in an ideal world.
Titanium is probably one of my favorite materials.. I just can wait till we start getting titanium springs to become more commonplace. Much higher fatigue life and lighter for the same spring rate!!! Just too bad it costs so much.

But these things don't change the fact that titanium is still a great metal for many applications.

Can you get by in 99.9999% of most engine builds with something else? Yes! Are there times when titanium is a poor choice? Yes!

Yup getting the right alloy is key!
although Grade 5 (Ti 6-4) will get you a long way...

It's strong and light. Titanium rods aren't going to break!

1 set are for HarryOz's 427 monaro turbo build. Another set are for a 427 n/a cobra. Oh and a 3rd set will be for my blown 427 TR8, eventually, lol. All Darton MID's.

(and just to keep it on topic) any pics of the rods?????

Chris,
Some parts are here including the rods:
http://www.pistonheads.co.uk/gassing...65605&f=69&h=0.
Heads are away being coated, pistons are on order, the plenums having the coolers fitted. I expect Harry's to come together in about 6 weeks

that looks amazing! what turbo setup is going in the manarno? how about for the TR8? how come you have gone for 427 over stroked LS1's???think you should buy an ultima and show everyone how to do it!
thanks (a very very jealous) Chris.
PS. need any weekend a helper????

Man titanium looks like crap (I'm wearing a titanium ring right now, definately doesn't hold its shine).

When it catches it stays on fire, a really hot fire and unless you have a large enough Class D extinguisher to put out a Bradly or a Striker it won't be fun. One hit from an RPG and it goes up in flame and just burns the entire vehicle into ash and slag.
It burns alot hence they even use it for some types of rocket fuel. The aluminum used in the paint on the Hindenburg is why the exterior skin went up so quickly as well (I even saw a documentary on that one).

Mmm, chemically.
*edit*
Oh yeah, mix Iron Oxide to Aluminum power. The oxygen bonds with the aluminum and makes a wonderful thing called thermite. Add enough heat (from maybe those gray sprinklers you used to play with as a kid) and the new molecule made from the Iron Oxide and Aluminum powder ERUPTS into a wonderful flaming unstoppable cacaphony.
My *** is on fire my *** is on fire!!!
If you use a grinder on aluminum and then iron you can make the dust literally blow your face off.

Genesis, the cranks are forged by callies. Rods are titanium.
Chris, don't need an ultima. A good TR8 ought to see one off plus it has boot space. Stevie T seems to better their figures already. Just goes to show what good work privateers can do.

My little brother and I use to make Thermite!
Fun stuff. 
Ti is also not friendly to being rubbed on. Ti springs are coated so the retainers will not beat them up.
People who say aluminum rods are not safe for the street are working on very old information. Get rods that are made of 7075 T6 and put an oil temp gauge in the car. They do not like very high oil temps. Not really an issue with street engine.
Stay away from 2014 rods. They will work harden and break with street use.

Special welder to weld aluminum? You can MIG weld aluminum just like you can MIG weld steel using the correct gas and wire. You can also TIG aluminum just as you would steel.

They're both the same thing yet they feel completely different.
Could you please elaborate on the manufacturer and application that you had first hand involvement with a Ti crankshaft?
Thanks in advance
