titanium engine parts

[alpina]

What are the downsides ( other than cost) to using titanium parts in your

mostly daily driver part DE motor IE. valves, retainers, connecting rods etc....

My Ducati has all 3 of those and a bunch more in the motor. No problems so far

30k and I flog it pretty hard on the street and track.

Cost
lack of any benefit on a street motor
Titanium is for eeking out those last few rpms's in a motor. For a street sometimes DE car I think you would be better off with more displacement for low end grunt instead of worrying whether you can push the rpm's to 8000 for top end.

On the other hand if you have the bucks, why not

Titanium is a wonderful metal but is life-limited in certain Automotive applications.

We use it for valve spring retainers, intake valves, and rods with the latter item a replacement part after so many hours.

One needs a realistic budget to use titanium engine parts aside from retainers.
