Going turbo and I'm wanting to put down "most" of my power to the ground lol. Here are the three candidates.

1. Helical (ITR)
2. Quaife
3. Kaaz


How much of a difference would the quaife make over the helical? And which is best of the three? Going in a GSR.

 

Well the ITR and Quaife LSDs are both helical ( torque biased) differentials. I believe the kaaz differential is a 1.5 way clutch type differential. You're going to want to go with a helical LSD for a street-driven car, and the install is relatively simple. Quaife LSDs are also known to be bulletproof. I say go with the Quaife

 

i have the ITR tranny and it works great!...

ps i also have a brand new itr lsd, 0 miles with ring gear hit me up if u are intrested in it...

 

Also have a ITR LSD for sale

But I would go with the Quaife.

 

if you have the money go quaife. But if your on a budget then go itr. hey i was kinda wondering about buying and itr lsd not sure can you guys pm me a price thanx

 

Quaife all the way. Good product and comes with a warranty. Thats all we sell and use on our race cars.

 

I haven't heard of the other brands, but I'm running Turbo on my ls and am buying a Quaife LSD also. Heard nothing but good reviews about them.

 

Alright looks like quaife took it lol. Man they're expensive though!

 

Yeah they are a bit pricey, but it'll be worth the money for it.

 

Well, what is the purpose of the car? Rally? No helical...go clutch-type.. Such as the Kazz... Drap or strip a helical will work...

Clutch-types are VERY high maintenance... And you have to run whatever fluid that Manu. recommends... A helical does not require the same maintenance, and you can run oem fluids...

Keep in mind that when a wheel comes off the ground, with a helical type diff, that wheel will get all of the power...

 

Yeah a 1.5 way Kaaz LSD would have its advantages for auto-xing and road racing but it sounds as if the OP is more concerned with daily driving.

 

The car would be a multi-purpose car. It would be my DD, see some autoX, some drag, and lots of spirited street driving and tearing through the mountain roads.

Agreed... I would say a ITR diff or a Quaife should do it..

 

go ITR

awesome,my first post on HT

Straight from Quaife's website...
"The Quaife torque biasing differential enables your car to accelerate quicker and corner faster. How?

By getting the power to the ground!

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).

In cornering, while accelerating out of a turn, the Quaife biases power to the outside wheel, reducing inside-wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed.

The Quaife also controls loss of traction when the front wheels are on slippery surfaces such as ice and snow or mud, providing the appropriate biased traction needed to overcome these adverse conditions. The Quaife Differential provides constant and infinitely variable drive. Power is transferred automatically without the use of normal friction pads or plates seen in other limited-slip designs.

The Quaife's unique design offers maximum traction, improves handling and steering, and puts the power where it is needed most. A definite advantage whether on the track or on the street.

The Quaife is extremely strong and durable and since the Quaife is gear operated, it has no plates or clutches that can wear out and need costly replacement.

The Quaife is great for street driving or racing. Racers don't have to put up with locking mechanisms or spools that created unwanted understeer under power, or in the case of front-drive cars, even tear the steering wheel out of their hands when cornering. Because it behaves like an open differential during ordinary driving, street drivers will have trouble telling it's there until pushing the car's limits."

 

^^^^ That means nothing in respect to my post... When one wheel comes off of the ground, and the other remains in contact with the road, such as driving over an fia curb, that wheel will get all of the power... This is inherent with Helical diffs... Quaife is no different.

But thanks for the post...

Multiplying zero torque by the torque bias ratio still results in zero torque. Physics rules.

I believe that Torsen makes a preloaded helical differential that addresses the problem of lifting a wheel. Too bad it is not available for Hondas. Another way to address this is with brake controlled traction control.

For anyone considering a Quaife, please read my exchange with the Quaife America representative.

Also, since Quaife will not disclose their torque bias ratio (the only numerical parameter that defines how well the differential is functioning), their warranty is essentially meaningless. As long as the differential is in one piece, it still works according to their wording. The ITR differential has a clear functionality check procedure outlined in the Helm manual.

I'm not saying that the Quaife ATB differential does not work, but according to my exchange with Ralph Hollack, it does not work better than the ITR differential.

 

^^ Interesting convo...
