nothing to do with carbon or ceramic discs. why are you disputing the obvious?
here is another populal race pad ($1100 both axis):

swinny, a ferrodo front set of race pads for a corvette is $750. the rear will be a bit cheaper. the rest of your post is not very helpful either.

i now see that correction factors in the brake energy...
"i would think that most passenges cars cannot lock the wheels at high speed (150 mph+)."
sorry, i meant to say 150 kph+.
not talking about high perf cars but the average car. so lets say we are looking at a $25k car, from 5-10 year ago (lets not discus this). take it up to top speed, 180-190...
nobody?
there is a plethora of info/papers on lokomotive, aero, and organic/natural fibre based compounds. where to look for high perf. stuff? surely there is something out there.
what pars are these? how big? what material? will you have it further heat treated after machining?
my interpretation of what has happened:
- part was forged
- part was (through) hardened
- part was annealed/tempered to specs at surface
the annealing must have been too short to soften the...
what has not been said:
- cof varies with temp
- cof varies with speed
- cof varies with pressure
(simple physics)
i would think that most passenges cars cannot lock the wheels at high speed (150 mph+).
if the original question was: will a "wonder pad material" with e.g a cof of 1.0 benefit...
the system will make max power when it is set up so that it reaches max boost at the rpm where the engine would make max power na (or a little above). compressor+turbine efficiency. boost should be higher than backpressure. (pressure ratio can be considerably higher at that point than if it were...
swinny, now you lost me.
looking at the graph, can you explain where the second 1400 peak comes from? i can see how the valve deccelerates when banging onto the seat, but how would that translate into contackt force? inertia would make the rocker tip lift, no?
there is no second peak here...
what op is after: "... where i can find a graph of valve tip force in a ls1 with stock cam (or similar engine)?" (citation from above.) exactly like the graph above. the same for lifter/lobe would be nice. other parameters like measured acceleration, stifness, friction, float analysis or other...
yes, i dont have "a few years in specializing ..." but i can differentiate between decceleration and acceleration (the later easily being able to exeed max spring force).
so would anybody know where i can find a graph of valve tip force in a ls1 with stock cam (or similar engine)?
this is an...
if you look at a graph of measured force vs. degrees you will see that what your saying might not be correct. why should the acceleration of the valve be limited by the decceleration available from the spring? i will dig up the graphs for other engines and try to post one here as an example.
can somebody point me to info on valvetrain forces in a pushrod engine, please?
im primarilly looking for valvetip force and lobe/lifter force on a v-8, (e.g. ls1), preferably real/measured.
at that time they still didnt really know what they were doing with ci. today gray iron doesnt crack and is welded, especially at the foundry. before going to steel you would use some type of adi today.
in case its not clear what im asking, here is an example for 17-7 ph (as opposed to diffusional transformations). im not aware of asm having published such a compilation.
does anybody know of a good collection ("atlas") of cht and ttt diagrams depicting sub zero kinetics of martensitic transformations? or of relevant data in another form? for stainless but also tool and other common steels.
