with a solid lifter you can be much more agressive with the ramp angles (meaning wider duration without needing to go for mental life), whereas a hydraulic lifter needs a fairly subtle ramp angle otherwise you can start to push the oil out etc
And a whole host of other issues like a hydraulic lifter jacking up with high revs (high oil pressure) leaving the valve open all the time

ye but sure that doesnt give a proper answer philip said their ground different to hydraulic cams..im asking what does he mean by this? like is the machine using a different technique or what?
Can't you read ?
They ARE ground different in terms of ramp angles etc..
I'm not that technical when it comes to camshafts but I can make sense of what Stuart is saying
O reli, I didnt read this 4 times on the last pagelol lol lol lol lolQuote:

No the grinding process (ie taking metal off the cam blanks) isnt any different.
The shape of the egg is different. Sometimes its not obvious as cams are incredibly complicated devices... There are entire books/engineering divisions for them etc.
Lol......... egg!
