Is titanium valves really worth the extra $1000ish dollars?

Lets hear the pros n cons

It depends on the intended RPM range of the motor, if you want to rev it past 8000 RPM then go with the titianum, if not don't

Well IMO it IS worth the extra money. Saving weight in the valvetrain is always beneficial. Just my

On a serious race engine you'll need the Ti valves. The Ti valves are actually cheaper on a race engine since you won't have to replace valve springs as often. All depends on the cam profile and the RPM that the engine turns.

I can appreciate that the titanium is a lighter valve, therefore you can spin the motor a little faster and it will save on valve springs.. So I guess the question I have... is spending the extra coin now really worth it, once my butt gets strapped into the seat?

Also, I was reading elsewhere that an inconel (or some super alloy) valve is recommended for the exhaust... since I'm more in favor of a bulletproof motorover squeezing out every last pony.. wouldnt I want to get a stronger/harder valve and not worry so much about breakage?

I would spend the money on a longer stroke to keep the RPM down so I don't need Ti valves

Its for a B-1 original 572 motor.. anywhere from 900hp and up... spinning at no more than 7500

Inconel valves are for turbo apps where the exhaust temps are much higher than naturally aspirated.

Depends on lift. I only spin my 514 to 7500 rpm but I'm close to .900 lift so the recommendation was to use Ti on the intakes.

We're also at .900 lift.. and after talking with my engine guy today.. He is solid on stainless steel for my application.. So I guess that means we are for sure going that route..

The main difference is, with the 2.30 valve, it is harder to control it with the heavier valve. A valve not controlled, is a bad thing so you need to run higher spring pressures. That's the trade off. I've used both and don't believe there's a performance gain, just piece of mind. I hope it runs to your satisfaction this time Don.

Head diameter, stem diameter, valve length, ramp speed and RPM are just a few of the factors in deciding on valve material. I'm not going to say I am smarter than David Reher (I'm not) but he and I agree that Ti is the only consideration for most ANY engine of today's geometry. It's just not worth messing with steel. Today, bracket engines are using lobes that are faster then Pro Stock of only 10 years ago. You can order lobes today that are so close to PS that it is unthinkable. Yet, guys continue to try and cut corners on valves.

I wouldn't consider steel.

BTW, it's one of the few things I wholeheartedly agree with DR. Not that he cares.................

What kind of lifespan does a ti valve and beryllium seat have?

I stopped using BC seats back in about 2005. I started using Nickel Boron (IIRC). They machine much easier. And last just as long. How long they last is hard to determine. Too many unknown factors. BUT...Ti will not last as long using CI or ANY brand of hard seat out there.

what about the wear on the valve face, and this hard coating they are putting on them?

You're going to be right on border with a Stainless intake valve that is 2.300" in diameter and 11/32. I would go Ti if you are going to spin it over 7000.

Thanks again everyone for your info... I spoke with the engine builder again yesterday.. Straight up told him I wanted to break the bank and get the titanium valves...

He flat out rejected that idea and used that polite "In all due respect" phrase... which basically means he refuses to spend the extra money and once again said I should save the money or upgrade to better heads and then get the exotic valves..

I guess that means he doesnt like B1 Original heads... but then he's a high horsepower, heads up racer...
