Yeah what is the problem with desmo? Too much weight in the valvetrain?

 

Who makes Comp 918 springs? PAC?

 

wow, that slow-mo vid was absolutely amazing. valve springs take a friggin beating. what rpm was it taken at?

 

We have developed and produced most of the high performance beehive springs that are currently available. We have a few extras that will be on our site here shortly.

That video was actually pretty smooth running at 7000 rpm with 0.700 lift on an old NASCAR Truck motor. We are working to get some more that show some pretty wild things going on at higher rpms.

A newbie question here: You say you will be using a solid roller cam. What are the advantages of using a roller cam over a hydraulic cam? Can a roller cam be used on the street? What cube motor are you putting it in.

 

Roller cam isnt 100% accurate to say in reference to a solid roller. You can have a hydraulic roller too.....

Solid roller cams can have much more abrupt valve events and higher lifts because you dont have to worry about a hydrulic lifter collapsing....It is solid so no collapse. "roller" is just in reference to the ends of the lifters.....roller, flat tappet etc
