Happy thanksgiving all. Curious what is the HP loss from the flywheel to th=
e wheels. IE what does 292 at the fly equivalent at the wheels?

Hi Bob,
i am pretty sure that Tran X is the same as a Salisbury LSD and is still av=
ailable through TR Enterprises here in the UK.
I do not know what car you are using (TR4 i think) so a new Tran X is proba=
bly ok. I have 2 Salisbury LSD units in 2 axles for my TR4.
However, if you are running a TR6 then I would recommend a Gripper LSD as t=
hey can handle the extra power and need a lot less maintenance than the Sal=
isbury (I swapped out and sold both my Salisbury LSDs for 2 new Grippers fo=
r my TR6).
www.gripperlsd.com
Of interest my TR4 produces 194 bhp at the flywheel and my TR6 produces 252=
 bhp at the flywheel.
Hope that helps,
Keith

 Hi,
I broke a diff at Thompson back in October and I finally did a post-mortem.=
 Looks like a couple of bolts backed out and when the shit hit the fan, the=
 4 or 5 that were still holding on sheared off. In any case, lots of metal =
bits in there. Some of the big pieces bounced around in the diff and there'=

assuming that I find no cracks in the center section, it it accepted practi=
ce to clean off the dings to prevent stress risers and re-use it or is this=
 a "tosser".
Speaking of Tran-X, does anyone sell those now or are we limited to Quaife =
and GKN? I see that Rimmer lists both of those units. To be honest, I'm not=
 a fan of Quaife because I have to run the rear a lot softer to prevent whe=
el spin in the tight stuff - that kills my times at places like Thompson an=
d Palmer (like 1.5 to 2 seconds a lap.) Speaking of GKN, I know nothing abo=
ut them other than "clutch type differential". Feel free to chime in if you=
 have experience with those units.

Also, I am nearly 100% certain that I was using new lock washers and Red Lo=
ctite high strength thread compound, so the bolts backing out was a total s=
urprise when I cracked the case open. I was assuming that the pinion head h=
ad sheared off based on how the car felt when the diff broke. It was BANG a=

Off topic - looks like I'm not driving at ButtonWillow, I got a reply from =
Joe Siam that he has nothing available for that date. Oh well. Look like my=
 budget is going to gears and stuff anyway... ;-)
