I agree. Solid is better on airplane. Maybe not in your Buick, but in airpl
anes they are.

Subject: Re: JabiruEngine-List: Hydraulic or solid....
Having owned both, and discussing this with 3 other owners at our field, I
am happier with my current solid lifter engine. My previous engine always r
an very hot oil temps (from new to 150 hours) despite many attempts to rect
ify. Oil was always very dark, even 1 flight after oil change. All solid li
fter engines on the field ran cooler. To do with hydraulic lifters? Not sur
e.... But that's what we all blame.

2 - Positive Valve Opening. Even at lower revs a hydraulically operated val
ve suffers from a =9Csoft and soggy=9D opening operation. By r
eplacing this with a positive mechanical lift, a more precise motion is ach
ieved. This leads to a faster change in manifold vacuum, greater gas speed
and ...more power!
3 - Predictable Operation. Hydraulic lifters are subjected to large and fre
quent variations in oil pressure and temperature. Solid lifters are a known
quantity that simplify valve operation and remove such variables.
4 - Weight and friction reduction. A solid lifter is 10% lighter than it's
hydraulic counterpart, and given the overall weight of CVH valve train, thi
s is an important bonus. Any loss of weight in this area will help with eng
ine efficiency and life expectancy. Also, a hydraulic lifter exerts a const
ant pressure to the total circumference of each lobe base circle resulting
in a certain amount of drag. A solid lifter does not contact the camshaft b
ase circle, so internal friction is reduced.
Remind me why they changed them?

Clive,
What happened to #1. I see #2,#3 and so on. Just thought to say maybe I'm the
only one to catch this? [Shocked] Thanks for your info. DonB

I am looking to convert my early hydraulic 2200A #2456 to solid lifter from GM,
(.842" dia.) I need adjustable rockers. Anyone have any for sale before I buy
brand new units??...DonB

It was plucked from a webpage about tuning race car engines and 1. was a
pitch from the company about them, the company.
I just tried to find it in my browsing history but drew a blank.
Wasn't anything positive about them, I'd have put that on, I do have an
open mind......about some things...:-)

Modern F1 engines do not use cams or lifters as the lifters cannot stay in
contact with a cam at the rotational speeds of the engines 18,000 rpm or
so. They are generally driven by air. The advantage of a hydraulic lifter is
that it always stays in adjustment. Mechanical lifters are a pain to keep
in proper adjustment.
