Breaking Valvetrain Parts? Check Your Camshaft Ramp Rates

Steve Morris builds engines for Manny Alvarez of HPP Racing. Manny was recently telling Steve that one of his engines was breaking valvetrain components after just a couple runs. Steve had built him a different engine that had been super fast and super reliable, so Steve asked Manny to send the other engine back to get torn down and looked at. Turns out, the camshaft was the issue. Check it out.

Often imitated; never duplicated! Steve Morris lady's and gentlemen!

The cam doctor will show all that, velocity, acceleration, jerk, ramp zones, etc. maybe I should do a video and explain the lobe area's and velocity ect?

thanks steve for another great video

I really like the idea of opening the intake earlier and closing the exhaust later. At least with a very mild initiating ramp which then leads to standard lobe characteristics.

If I remember right the pro Stockers learned the hard way about the same thing years ago

Isn't Manny Giuseppe Gentile? Great content brother.

[@Bill-flatplanefool]

At this point I just want a cam lol 😊

[@daveb1870]

So how close is the correlation between the ramp rates and spring harmonics? It would seem to me that the two are almost inseparable?

Simple Steve🤣
