7 different types of differentials
open diff
locked or spool
torsen
dana lock-trak (used on corvette)
salisbury
viscous
electronic traction control
i noticed you tried to list 7 different types of differentials, but you listed 3 variants, not 3 different. there are 7 completely different types for you. and since your hung up on this quaife lsd that you know nothing about, are you aware you can use a companies patent if you pay them so much/each unit sold? i said quaife uses a torsen II set-up, meaning its all gears, with no clutches or "clutches." and in a viscous lsd, the "clutches" act so simliar to a clutch that the author himself refers to them as "clutches."
and bla bla bla bla bla. this is done, im gonna move on, so why dont you do the same?

so tell me what car a helical differential sits in.
this makes me laugh,
helical
1-way
1.5 way

you think you got me caught pretty good with words in your post, you did the same thing.
and explain to me how knife-edgin the intake divider is bad for flow? you say blunt nose dividers are better, then how come f1, cart, and indy cars dont have blunt edges on their wings? and on nascar, why do you suppose the rear body panel ends with a 90* bend ? because it creates a clean break for the air to flow from.
bernoulli's equation describes the condition existing in the free stream, outside the boundary layer. it deals with pressure and velocity as air flows smoothly around a body. it is based on a perfect fluid and is really a statement of the conservation of energy in the fluid stream.
simply put, what cuts thru the air quicker, a bat or a knife?
bernoullis equation indicates that if the dynamic pressure is increased, the static pressure in the stream must decrease. meaning, when you swing a bat thru the air, it cuts thru the stream smoothly and forces the air to increase in speed because it must travel a longer distance. as for a knife, it simply cuts the air stream into two, keeping speed (velocity) the same because the distance it must travel has not been altered. but all of this is in ideal conditions. but on top of all of that, the bat will cause the air stream to stay tight to its surface, thusly creating turbulence from any imperfections on the bats surface.
convert this over to intake dividers- if you bull nose the divider, you create a longer path the air has to travel, you increase turbulence, while causing the charge to flow faster theoretically. if you knife-edge the divider you create a shorter path the air has to follow, less turbulence because the charge isnt "hugging" the divider, while keeping its air speed constant, idealistically. now what does the honda head suffer from? turbulence in the ports, just like every other head. the importance of p&p'ing a head is to decrease turbulence so you can increase the intake charge speed. so if you bull nose the divider, that means you must polish it that much more to rid it of any and all imperfections it might have on its surface. now this will effect atomization (because atomization is a factor because your injector doesnt run trouble free for the life of the engine) and dispersion. now there is the case against heavy polishing, which leaves only one option-better port work. you can knife-edge a divider, touch it up with a polishing bit, and leave it at that. to clear everything up, you should open your intake ports by more than 2mm in any direction, but it should be opened. most of the time and energy should be spent on smoothing out the intake port so the intake charge has the cleanest, quickest route to the combustion chamber. also to boot, when you force air from a smaller runner into a larger runner, it cools the charge, that is why venturi plates are used on my top race applications. ericks racing has tb's that have a larger od while they constrict the id, they do that just to cool the air before it enters the intake manifold.
like ive said, im done with this because you are not as well educated as you think you are.

So I suppose the builders of F1 racers, and the proponents of blunt-faced intake dividers are wrong, and you alone have seen the light, correct?
I'll leave you with a quote from The Old One:
Things of note are the symmetry of each bowl, the blended seats, and the width of the "blunt" divider. We keep this wide and softly radiused because it reduces the tendency for turbulence that's often associated with sharp dividers. Remember, the leading edges of airfoils aren't sharp.

The point of the thread which you obviously missed, was to point out that nobody is perfect. I don't really feel like typing a long response, it's been a long New Year's and I'm tired.
The point, since you still don't get it:
When you have a discussion (this is a discussion forum if you didn't notice) there is no absolute right answer so you should stop trying so hard to come up with it.
That's the end. If you for some reason cannot comprehend that one sentence which I just typed, I don't know what to tell you. I've already tried to get the message across in so many different ways and it's just not sinking in. I'm not trying to hold a grudge, I just want you to chill out and talk with people instead of trying to "school our azzes" as you so eloquently put it.
The thread which I stickied obviously got your attention so out of courtesy I will unstick it and let it float to the bottom.
