Careful where you buy them!
A mate got a couple of sets on Ebay and i arranged to go halves with them on them.
When i inspected them they werent fit for purpose and we both ended up with some nice paperweights.

have you ever seen how many different alloy types there is of Titanium

ah of cause,,,, i do know very little about big engines though

The titanium has to be coated for crack resistance. The surface has to be treated very thoroughly in order to precent fatigue lines forming, or they will fail after a short mileage. They have 25% the elasticity of decent steel, which is why they tend to crack. The weight saving of a proerply treated titanium rod is 12% over a steel, and around 75% of the strength.
Defo suited to NA engines imo, i defo wouldn't bother.

yea, loadsssss lol. new vette uses them too. It seems that there is something to be gained in terms of a little weight saving. But i just wouldnt trust one in a custom application if it's unproven.

You are saying if you made two two rods to the same strength the steel rod would always be lighter!
May be it is to do with the fact that with titanium you can use more material to create stonger shapes/structure.

There is a considerable difference between a manufacturer developing and designing a set of rods for a production car, and a few people on a forum buying generic rods from a.n.other company (even Arrow).. I wouldn't want to risk it personally, can't really see the need either..

Doug - they're the figures from an engineering paper, and yes they sound strange. I think it must be to do with the shape, but if u do two exactly the same - they are the figures that you get.
It seems that steel is stronger for lower rpm's, (sub 11k) and ti for higher rpm's.
