I've been looking and just trying to see if there is manufactures producing lighter b-series valves. Companies may be able to shed some grams with different retainer designs and different weight rods, but what about the valve itself and still be durable. Does anyone know of a lighter/est b-series vtec valve on the market??

 

You will want to take a look at Ferrea 6000 series or competition plus valves, those are usually between $15-$35 per valve though.

 

Stock PR3-intake valve weight 47g and P73 little bit less. Of course every gram count, but I think that there isn't big variety between steel alloy valves (exception hollow stem ones). If we don't talk just shelf products, lightest B-series valves on the market are probably made of titanium. For example PR3 intake valves titanium equivalent weight ~26g.

Here is some weights from valvetrain what I've measured:

-PR3 Intake valve 47g
-Stock retainer 13g
-Supertech retainer, ti (RET-K20A2/T2) 7g
-Ferrea locks (K10034) 1,4g/pair
-Ferrea retainer, ti (E12020) 3,7g
-B-VTEC rocker arms 262g
-LMA spring (14820-PCB-305) 27g
-Valvespring Supertech, outer (SPR-H1002D) 32g
-Valvespring Supertech, inner (SPR-H1002D) 11g
-Valvespring Ferrea (S2014) 34g

 

Ferrea 6000 Intake is 43 grams, exhaust is 39 grams. We make a Titanium valve that is 24 grams, but a set of 16 will run you $2000. Hard to compare that to a $240 set of 6000s

 

No joke about the price! I was just curious. I've been building and racing here and there for awhile. But I have never tried comparing valve weight. I will be checking out a set of those 6,000's.

Curiosity, would there be a down fall of life to the titanium valve in the oem steel guide?? Life expectancy?

 

And thanks for sharing your info!!! Much appreciated!!!!

 

We use bronze guides and softer beryllium seats when we use Titanium valves. They don't last as long on a steel seat. They also have a coating for longer life.
