Subject: Team3S: 10W40 in the tranny?! (WAS Manual Tranny Fluid)
 
What's this about using 10W40 in the tranny?! I have never heard of that...
Obviously benefits are that you get a thinner oil so it does not take as
long to get around. (My tranny shifts rough first few blocks) What are the
downsides?

I don't know abou the local stores in your area, but I can tell
you it was pretty easy to order it online for me.

Refer to the viscosity comparison chart at the url below to see that 40W engine oil is similar in viscosity to 90W gear oil.
 
http://www.bobistheoilguy.com/visc.html
 
The 10W40 engine would only be "thinner" than 85W/90W gear oil when it is cold.
 
Jim Rowe at Metric Mechanic has in the past recommended Amsoil 10W-40 fully synthetic engine oil for Getrag Transaxles. I don't know Jim Rowe so I don't how much confidence we should put in his recommendation. We can probably be sure that engine oil is not going to harm the "yellow metal" (soft synchro parts).
 
The downside or 10W40 engine oil? Perhaps not sufficent friction for quick engagement of the synchronizers? I really don't know. I have Pennzoil Synchromesh in my Getrag 5-spd and I find the shifting *noticebly* improved to when I had Red Line in there previously.

Subject: Team3S: A different question on rotors
 
This is sort of a general question on cars.  What kinds of pressure do brake rotors see?  I assume that they are as thick as they are due to the need to disipate heat, and not to resist bending due to the pressure.  Is this a correct assumption?  And if heat were not an issue, how thick would they have to be?

Rotors see equal pressure from each side so thickness is really not an issue, it's
a clamping force. Motorcycle brakes are a few tenths thick. You may need a half inch
to stop a 4000 pound car from 80 mph once --- if you want to repeat the process
you'd better have good cooling or more mass. Drag cars have small brakes [ read this
as low mass ] just because they only have to stop the car from speed once per race.

I notice that a lot of rotors are made up of what looks like two plates with a baffled open area inbetween them.  So they must be resisting bending enough to avoid being clamped together, right?  That's probably more a function of the baffling to hold teh plates apart, but assuming those were not there, how thick do you need to not bend?

I have seen solid rear rotors on certain disk brake cars that appeared
no thicker than 1/2"

The baffling, or air space is for cooling only --- I don't know what the minimun is for
disk thickness with cooling vanes but assuming it only needs to stop once you could
probably get by with 1/10 th on each friction surface with cooling vanes spaced an
inch apart or so apart and 1/3 of an inch thick.
 
what is the object of the question ??? Are you planing on redesigning your brakes.
 
Willwood has a varied selection of oddball rotors for you to look at.

Subject: Re: Team3S: A different question on rotors
 
The purpose was really more of a thought exercise than anything else.  I am curious how brakes would be designed if it were not a matter of warping due to heating and cooling, i.e. if heat were not an issue.  It seems the thickness of the rotors seem to be pretty consistent within a small degree.  The process led me to think that if you till wanted to use the two plate method, how much is enough to avoid clamping the plates together under hard braking conditions.  I was also thinking about bleeding off the heat.  Is it a good idea to bleed off the energy very quickly, or does that contribute to the warping, or even make it worse?  Or is it that the rotors are heated, cool perhaps only a little, and the are heated again that is the main mechanism for warp?  Would being able to cool off more faster extend or reduce the life of the rotor if the metal were thinner?  Really I've been reading the posts on brakes and seem to be hearing some things that conflict, at least to me, and these are the questions that I've come up with.

Subject: Team3S: Engine hit the floor???
 
This morning we were taking the engine off of the engine stand.  We had it
on the hoist so we lower it to about 2 in from the garage floor.  As we did
that one of the safety pins that hold the long "legs" of the hoist came out
and the engine hit the floor from height of about 1 1/2 in.  The oil pan did
not even get scratched or dented, no visible damages. My engine just got
rebuilt with custom forged pistons and valve job.  Should I be concerned
about anything???  I assume that the engine should be able to resist such an
impact.
 
Thanks a lot
