Quaife LSD vs TRD Helical..

[gts24]

So I can get either one of these LSD's.

Quaife has a lifetime warranty even if raced.

The TRD one is well, it's TRD. But it's TRD Japan. So there really isn't a warranty implied there, but I think that if you take your car in for warranty work and you have TRD stamped on there it's probably gonna look a lot better to a tech (if needed).
So which would/will you get?

[Pribilof]

Quaife.

Were would one go to find a Quaife diff.? I'm interested in knowing more about it. Thanks.

K, any reason why? please explain a little furthur... thanks

I'd go with Quaife because I don't want to be tearing my tranny apart all the time to adjust a clutch type LSD, you cant find the TRD helical anywhere and if you did who knows what it would cost you. Quaife warranties for life even if raced. I forget who makes TRD's LSD for them but I'm sure Quiafe's is as good if not much much better than TRD's. Quaife has an excellent reputation for building LSD's, gears, full trannies, etc. Whats not to like about Quaife?

Oh, and Phantom Grip has a HORRIBLE reputation. It's probably better then our stock open diffs, but its a far cry from a good LSD

From Quaife's site:
The Quaife Differential powers both drive wheels under nearly all conditions, instead of just one. With an ordinary open differential, standard on most cars, a lot of precious power is wasted during wheelspin under acceleration. This happens because the open differential shifts power to the wheel with less grip (along the path of least resistance). The Quaife, however, does just the opposite. It senses which wheel has the better grip, and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.

In drag-race style, straight-line acceleration runs, this results in a close to ideal 50/50 power split to both drive wheels, resulting in essentially twice the grip of an ordinary differential (they don't call open diffs "peglegs" for nothing).

Pribilof: dude, how do you like your valentine1? n what did you pay for it?

[t2000gts]

how does an LSD affect/improve handling?

[erok]

An open differential sends power to the wheel with the least traction. A limited slip differential sends power to the wheel with most traction. To put it very simply; power + less traction = wheel spin. Power + more traction = acceleration.

IMO, putting an open differential in the new celica was the single dumbest thing Toyota did in designing our cars. How much more could a LSD possibly have costed Toyota to install in the factory? $500? Maybe Dave Draper can give us the dealer cost on a new open diff for comparison.

I think the reasoning of Toyota at the time was, "This is going to compete with the Honda GSR no need to add a LSD".

I'll add more like $1000+ on the sticker price of the car plus think of how much them they would have to stock in all the dealerships across the US. Its a pretty expensive exercise from their viewpoint , where the majority of Celica owners would'nt know what a LSD is or how it functions.

All I can say its a shame they did'nt put it into the car in the factory as stock equipment. Oh well, I'm ghetting one later on anyways.

Bingo.

While a lot of people who hang around here see value in a limited slip diff, most Celica shoppers would say "Huh?"

I'm sure Toyota's thinking was to keep the price low for the 90% who wouldn't appreciate an LSD, rather than cater to the wants of us rabid 10%.

That said, I'd love to have one too...a "Type R"-type version could have allowed catering to both needs.

[scapamouche]

And make up for the single biggest weakness in the Celica for autox. Make us more even to start with in DS. The driver is more, of course, but you can't sneeze at a better mount for the driver...

[autxr]

The problem is, it DOES NOT add $1000 to the price of the car.

What does Toyota pay for a standard diff? I dno't know either, lets assume $200. What do they pay for a LSD unit? I can get a Quaife for $800, so lets figure Toyota can get them for $600.

Difference? $400.

Installation is the same, because it goes in when they build the car, they don't need to spend a day taking the car apart and putting it back together.

no i think the looks fast thing was the dumbest thing

[F22-Raptor]

I got the Valentine 1 as well and it is sweeeet. Saved me about 12-15 tickets already. Tried some of the other Escort 8500 and all that but I know the owner of V1 (his kid goes to the private school I worked at for 5 years) and the V1 is simply the best you can buy. Period. Oh I paid 399 for it.

[Xlr8_10]

cool F22, you got the hook up with the dude? if so spread the good fortune. =)

[Pribilof]

I agree with autxr, +$400 MAX to the sticker price. One of the main reasons I want a LSD is because I have a steep gravel driveway and its a B1TCH to get up because my wheels spin... not both of them, just the one with NO traction. And since it's that wheel which gets all the power, I don't go anywhere. It's the same story in snow. Have you EVER driven a front wheel car that drives so poorly in snow? or in the rain?

[Pribilof]

while we're on this topic, here's something I was wondering yesterday when I had a flat. Let's say you put your donut spare on the rear of your car. You can drive as far as you want on it without f'ing up your car because you're not going to burn up your differential because the rear doesnt have one. Now lets say you put it on the front. Can you also just drive around as long as you want with the donut there? Since we have an open diff, that wheel would just become the drive wheel, correct? And since an open diff transfers to the path of least resistance, there isnt any risk of burning it up like a LSD.

Am I correct in assuming all this?

I think that to answer this question you simply have to look towards cars that come with an LSD standard. ie Type -R and the new sentra ser spec v..... and I'm gonna assume they have a spare...
