Finally some available?




Rollers on both ends.

 

who? where? how much?

 

there spot on

 

they look nice shame you wont see them one cover is on

 

newman cams should make these would stop most of the cam wear problems on the CVH

 

look rather tasty

 

I still can't understand why these aren't made by someone! They hardly look complicated to design and they would sell by the bucketload! I can understand why Newman/Kent/Piper haven't produced them.... because it would mean our cams would last which means they'd loose money

 

Roller rocker arms will not reduce camshaft wear!

The flat lifters still ride on the camshaft lobes - this is what wears out.

Now if you went to roller lifters - that is another story.

 

does that turbo look big???

 

So whats the advantage of these then? Reduced rocker arm wear??

It does, but it is wearing a heat shield!

 

I already know about these and am in touch with the guy that was in on the manufacture of them. I don't think they have been tested yet.

 

Yes, but also looks like it is top mounted.

 

Titan do roller rockers for cvh engines. I remember Anna Rose selling the set she had on her track car.

 

Why fit them, what do they do over normal ones??

 

Interesting.

Do we know if they are the same ratio as the standard rockers? I am assuming that they probably are.

 

they look well smart, and look alot stronger than they old ones.

 

Roller rockers are infinitely stronger than standard steel rocker arms and are more resistant to bending and breakage under high spring pressures at high rpm. Standard pressed steel rocker arms are prone to failure in high performance applications. A high rate of fulcrum wear, flexing, cracking, splitting and breakage are common problems that will result in power loss or possible piston failure due to detonation of the incoming air/fuel charge. The traditional metal tip on standard rockers literally drags across the valve tip as the rocker opens and closes causing high side loading on the valve. This inside force leads to irregular and rapid valve, valve guide, and valve seat wear in many engines. The roller tip on roller rockers eliminates this side loading action.
The use of needle roller bearings at the rocker fulcrum combined with a roller tip at the valve greatly reduces horsepower robbing friction in the valve train to provide a measurable power increase over standard rocker systems. The reduction in friction with roller rockers has additional benefits of reducing the operating temperature and foaming effect of engine oil to provide a cooler running engine.
Unlike standard steel rockers, roller rockers maintain a constant indicated rocker arm ratio throughout the full valve lift because the centre line of the roller stays constant and only its contact with the valve stem center line changes.

 

Ok that explains it!

 

who i smaking these then


i was onto titan ages ago about these but didnt get too far
i know karl nms was doing them but he stopped using them for reasons that went over my head
