 Scott,Just my two cents worth (no cash value), but we have a Detroit locke=

 pushing the car. Bear in mind that neither us, nor our cars have ever been=
 described as super-fast. I do notice the difference when racing my Bugeye =
with an open diff, as it lifts the inside rear and loses drive.=C2=A0

We have run a QUAIFE for 30 years and it has been flawless in the TR4.

Scott, I went from a welded diff to a Quaife last year. Easier in the
paddock etc to drive and push around. In the corners, less fighting the
wheel, more point and shoot. Downside, I'm getting some wheel hop when I
hit the gas. I've been making suspension, tire pressure and shock
adjustments to dial it out, almost there. For the K Cup (and not one of the
fast cars), I put an old welded diff in to get a better ratio (3.89) vs the
normal 4.11 Quaife. Not sure I made the right call, no idea how many hills
were at RA, but with all the settings the same, no wheel hop so it must be
caused by the Quaife.

GT6 diff in the car for the big stub axles, Quaife PN QDF8K. I ordered it
last spring directly from Quaife when the exchange rate was pretty good.

Hi Scott,
I=E2=80=99ve run both a welded diff in the #114 (Dads car) and a Quaiffe in=
 the #80. =C2=A0On the same track, I find high speed sweeper corner speed i=
s much better with the Quaiffe as the welded diff requires modulating the t=
hrottle to control the forced oversteer, where the quaife car is flat out. =
=C2=A0Last turn at Thompson, the #80 was 11mph faster exiting the corner wi=
th the same driver. =C2=A0 However, on the hairpin, the welded diff was a m=
uch better performer where the quaife required a VERY smooth line and was m=
odulating wheel spin where the welded diff just rotated the car and shot ou=
t of a turn. =C2=A0 I=E2=80=99ve developed a simple questionnaire to help. =
=C2=A0Lap times were the same on both cars.
1. =C2=A0Do you drive like a madman? =C2=A0If yes, run the welded diff2. Ar=
e you a smooth driver? =C2=A0If yes, the quaife rewards smoothness. =C2=A0

LOL
I have not driven a Gripper diff

I hope that helps!

I don't know what the "Gripper" is, but if it is anything like "Phantom Grip" that you add to a stock diff to create friction to "lock" the two sides, It doesn't work.  The Quaife works fine until you lose drive on one of the two sides and then it totally uncouples the diff from the drive train.  You end up pushing the car off the track.

The k car uses the Quaife  “ Torson” design . It’s average ! But that’s all that was available 20 something years ago when I restored that car.

My preference is a clutch style ( Tran-x/ 3D) . They’re tune able ( break away- the amount of Lbs it takes to loc up) and can buy individual parts should you need them .

thanks, Dave.  Well, I have a welded diff - it requires some input to =
work - does that mean I drive like a madman?  Interesting, your results =
are the opposite of what I would have expected.  I assumed the welded =
diff is more of an inhibitor in tight turns where it wants the car to =
understeer, and on sweepers the wheel speed differential would have less =
of an effect.
Guess I=E2=80=99ll just have to try and find out.  Don=E2=80=99t like =
the idea of any wheel spin though.

Hi Scott,

I=E2=80=99ve run both a welded diff in the #114 (Dads car) and a Quaiffe =

flat out.  Last turn at Thompson, the #80 was 11mph faster exiting the =

1.  Do you drive like a madman?  If yes, run the welded diff
2. Are you a smooth driver?  If yes, the quaife rewards smoothness. =20

LOL

I hope that helps!

some input to work - does that mean I drive like a madman? =
&nbsp;Interesting, your results are the opposite of what I would have =
expected. &nbsp;I assumed the welded diff is more of an inhibitor in =
tight turns where it wants the car to understeer, and on sweepers the =
wheel speed differential would have less of an effect.<div =

 From the web site, the Gripper is a clutch-type differential like a Salisb=
ury.
If you want adjustable ramps, then Gripper looks like a good option. If you=
 want a no-drama diff, get a Quaife and drive s-m-o-o-t-h.

   I don't know what the "Gripper" is, but if it is anything like "Phantom =
Grip" that you add to a stock diff to create friction to "lock" the two sid=
es, It doesn't work.&nbsp; The Quaife works fine until you lose drive on on=
e of the two sides and then it totally uncouples the diff from the drive tr=
ain.&nbsp; You end up pushing the car off the track.

Thompson fall finale and Watkins Glen, July Sprints, same diff, welded
(2021) vs Quife(2022), in both cases marginally faster with the Quaife.  In
the case of the Quaife results, I was still getting wheel hop, backing off
exiting the corners, so not the best I expect to get from it. New rear
spring, less camber, this year but track conditions (wet) at Thompson make
the 2023 comparison (not included) moot.
Best lap welded -
Thompson -
1:34.692
The Glen
2:46.708

Best Lap Quaife -
Thompson
1:34.372
the glen
2:46.202

Scott,
Just my two cents worth (no cash value), but we have a Detroit locker in th=

at RA, and frankly don't notice any difference except in the pits or pushin=

Keep in mind that the question was a GT6 question,=20
The top 3 GT6=E2=80=99s at the Kastner Cup were all running welded Different=
ials.=20
I have run both a limited slip and welded in more than one GT6 racecar.=20
To me there is no comparison.
Welded wins.
You have to be a very deliberate and a careful downshifter for certain.=20
But, All the power you need is ALWAYS there.
Without exaggerating....The fastest times ever turned by A GT6 at Road Ameri=
ca Were recorded this past weekend during the Kastner cup.=20
The welded Diff is the fastest setup for a GT6, period.=20
With a minimum of an additional $600 fee For the limited slip, I see no reas=
on to switch unless maybe it might last longer and you would like to go slow=
er.
If you are a good driver, The winning answer seems to point toward welded.

Can't keep my mouth shut on this one, lots of great advice so far.

Jack ran welded diff in TR-3 back in the day, he reported push unless he 
kicked the tail out.  Taught him bad habits he had to unlearn when he 
went to a formula vee where smoothness rules. When he built his TR-4 he 
did the Quaiffe diff so I have experience with that one.

The three main LSD's are

Gear type (Quaiffe), clutch type (Gripper / Salisbury), detroit locker, 
I guess also viscous coupling but I'm going to ignore that one.  This 
would be like a Nissan or Subaru LSD probably.

As mentioned, the gear type diffs reward smooth driving.  If you lift an 
inside rear wheel, it WILL spin and you will lose some but not all of 
your drive (open diff you lose all).  In Jack's car, I suffered from 
that but Jack didn't after learning to be smooth in the FV.  Forced me 
to pat attention to smoothness.  Gear type diffs are pretty bullet 
proof, they rely on some creative use of worm drive gears as I 
understand it.  If both wheels are on the ground, it will transfer 
torque to both properly and not spin the inside tire.  Overheating 
doesn't appear an issue.  There are very smooth in engagement - can't 
feel it.

Clutch type have many adjustment options if you choose to use them.  
They require some care in what lubrication you use since they are using 
clutches in an oil bath.  The clutches can wear over time so there is 
some maintenance needed.  They can also produce heat when being actively 
used, that can be an issue in longer events.  They can keep an inside 
wheel from spinning when off the ground.  They are progressive in takeup.

Detroit Locker is not generally available in the TR diffs, they are rare 
in the big TR's, not sure if they are even available in GT-6 / spit.  
They act like an open diff on corner entry so no push but act like a 
welded diff on power on exit of turns.  They are mechanical, reliable 
and not sensitive to which lube you're using.  This is the one that fits 
MY driving style.  You can feel them engage at times - I don't notice 
while racing but do notice it in the rain or when pussy footing around.  
Would be horrible on the street I'd think.

Cheers, Tony Drews

I am the smooth madman.
And a further fact analysis has to do with oil volume=20
The limited slip unit installed inside the tiny GT6 diff case takes up way w=
ore space than the welded spider gears. Thus the welded setup allows you to u=
se more oil which is critical.=20
Generally speaking the GT6 Differential requires more oil volume not less.

Fascinating and accurate run down Tony.
Since I sent you a personal congrats a few hours ago I’ve been mentally reminiscing about when you graciously let me drive the Red Rocket in the RA enduro years ago.
Remember when I went out for practice and came in after a lap or two and told you about the banging I heard coming out of corners?
With helmet on and car running you explained I was only hearing the Detroit Locker engaging, said “don’t worry about it” and sent me back out. I had never used a DL in anything but a straight line and although I found the noise a bit disconcerting, I took your advice. Sure didn’t want to )and didn’t) break a borrowed car but boy was that fun! 
Congratulations again and all the best.

In Jack's car, I suffered from that but Jack didn't after learning to be smooth in the FV.  Forced me to pat attention to smoothness.  Gear type diffs are pretty bullet proof, they rely on some creative use of worm drive gears as I understand it.  If both wheels are on the ground, it will transfer torque to both properly and not spin the inside tire.  Overheating doesn't appear an issue.  There are very smooth in engagement - can't feel it.

The clutches can wear over time so there is some maintenance needed.  They can also produce heat when being actively used, that can be an issue in longer events.  They can keep an inside wheel from spinning when off the ground.  They are progressive in takeup.
> 
> Detroit Locker is not generally available in the TR diffs, they are rare in the big TR's, not sure if they are even available in GT-6 / spit.  They act like an open diff on corner entry so no push but act like a welded diff on power on exit of turns.  They are mechanical, reliable and not sensitive to which lube you're using.  This is the one that fits MY driving style.  You can feel them engage at times - I don't notice while racing but do notice it in the rain or when pussy footing around.  Would be horrible on the street I'd think.

Very well summarised, thank you Tony and congratulations for the Cup, great to follow the legacy !

I do run a Gripper in my TR3, which is indeed a plate type LSD, but with the advantage over the other Salisbury plate LSDs that the clutch discs do not have a friction material coating.
 
Therefore they (almost) do not wear vs the usual coated discs, which can wear very quickly under hard use.

Advantage over a Quaife : again, as the other plate LSDs the Gripper is fully adjustable and does not need traction on both wheels to work, meaning it works on snow (very useful here for Winter rallies in the Alps), slippery surfaces, and in case of wheel lift, where the Quaife is lost, as it needs an amount of grip both sides.

I run the car mostly in hillclimbing (and road as well, it is street legal) and the gripper does its job very well. Some track as well, but no experience with a welded diff to compare.

It would be interesting to see what the other Tony in the UK (Tony Sheach) who is road rallying intensively in the UK uses and says (Here is a hint: he wrote to the list in 2014 "Conversely, real men have rear wheel drive with plate type limited slip diffs .... I rest my case m'lud.")

Take care dear Foters!
