I was wondering what are the advantages of the titanium retainers, since going to titanium valves is not that really worth it unless you spin the engine very very high...

Thanks

 

Because 'weight' is a valvetrains #1 enemy. Titanium valves are mucho dough so they aren't feasable for everyone. Titanium retainers on the other hand, are not too expensive and will lighten the system a little.
More bang for the buck... without taking out a second mortgage..... well you get the point.

Yeah... we spend near $90 each on Ti Del-West valves... big $.. in something thats gonna get hammerred.

Ti retainers arent a bad deal, but theyll never be as durable as steel. If they are needed, we'll use them, but for the most part, we go with steel b/c it's safer & lasts longer & for most applications doesnt hurt.

Still, I agree with MG, reducing valvetrain mass is always a good thing.

 

Reducing mas everywhere is a great thing.. even more when it is rotating mass...

But is it worth the extra $ and the less durability in terms of performance? I think is better to change supercharger and get to 10psi +

 

Any thoughts on getting the titanium valves?? is it a good idea? power gains??? or revving gains??? this is for a sueprcharged car...

 

Titanium valves are one of those last things you look at. If it's a race engine turning high revs, Ti becomes an attractive valve because it can help valvespring life considerably. Especially true of engines with longer valves. Plus, you don't need as much spring to control the valvetrain... although losses there are probably the least important.

For a supercharged engine that's not going out for "quickest doorslammer" award, I'd stay with a severe duty stainless valve. Even in an all out race build, you'd use titanium on the intake and inconel on the exhaust due to the heat (supercharged/turboed etc).
There are other ways to lower the system weight. Shoot me a PM.
