If you are planning to run a high horsepower turbo/supercharged motor, don't bother with Ti rods; get some 4340 rods and spend the money on something else that will actually make more power...
On the other hand, if you are trying to win some specific class, and the rules allow Ti rods, and your budget allows for their cost, and there is some financial gain to be had in beating the competition, then the use of Titanium rods would be justified...
Titanium itself doesn't really make any "magical" extra power; it lets you drop the mass of the reciprocating assembly, allowing you to "potentially" raise the safe operating RPM of the lower end, but when you have gotten to that point, stresses go through the roof with increases in rpm, as opposed to the moderate increase of stresses induced by more radical levels of charge stratification.
So, if you are going to run Titanium rods, the geometry of the motor better be pretty shit-hot, and the valvetrain better be good for more than 10,000rpm, and all of the other exorbatent costs associated with super-RPM motors... and it's lifespan will be measurable in hours rather than the years available from a moderatly high output turbo/supercharged motor...
As one noted engine builder said, "RPM is an acronym for ruins people's motors!" High RPM is exactly what Ti rods will let you run...
