[DeTomaso] Quaife ZF-Q transaxle

[Garth Rodericks]

Details on the new ZF-Q transaxle: 
  http://www.gt40s.com/forum/gt40-tech-powertrain-transaxles/20751-zfq-new-proposed-gt40-transaxle-3.html
   
  The price of the trans in the US ready to install with CV output shafts and GT40 top plate will be $11,800, the price of the trans in the UK is £5995.
   
  As one guy said earlier, this trans is like a modern version of the ZF on steroids and is truly capable of handling 550 Ft lbs of torque and 600 BHP. The ATB differential and chosen gear ratio will make this trans outperform the old ZF unit. The ATB diff carries a life long Guarantee for the purchasing owner, The gear set and casing carries a 1 year parts Guarantee.
   
  The bolt on racing oil pump will be sold as an optional extra for approximately $475.
   
  The first 10 transmissions will have a promotional discount of $1000. As Martin said we have already sold the first one, orders are secured with a deposit of $1000, or £500.
     
  Excerpt from the thread:
  The ZFQ is fitted with the Quaife ATB diff below is information about the ATB from the Quaife web site.
   
  What is a Quaife ATB differential?
  The 'Automatic Torque Biasing' differential is Quaife's unique patented design, and is an after-market differential that provides smooth, constant traction for racing or slippery road conditions.
   
  Suitable as an ideal replacement for any front, rear or four wheel drive application, these ATB differentials have the added benefit of no adverse effect on the steering of a front wheel drive vehicle.
   
  Quaife ATB differentials have been used in a wide array of applications, from Formula 1 cars to emergency and public utility vehicles, where all weather mobility is essential, and where the product must perform in the most demanding of conditions.
   
  Available to suit a very wide range of vehicle applications, from Alfa Romeo to Volkswagen and including Ford, BMW, Honda, MG & Rover, Vauxhall/Opel, as well as a range of light commercial vehicles.
   
  The characteristics of the differential are that it progressively locks as torque increases; there are no plates or clutches to wear out, as the more conventional limited-slip designs incorporate. The ATB differential is particularly effective in combating the effects of FWD torque steer and understeer.
   
  Quaife Engineering also offer their ATB differential with a lifetime warranty [see terms and conditions], as a demonstration of the quality of the product.
   
   
  The Ultimate Differential
   
  The Quaife Automatic Torque Biasing Differential enables your car to accelerate quicker and corner faster. How? Simply by getting the power to the ground!
   
  The Quaife differential powers both drive wheels under nearly all conditions, instead of just one.
   
  With an normal open differential, fitted as standard on most cars, much precious power is wasted through wheel spin under acceleration. This happens because the open differential shifts power to the wheel with less grip - along the path of least resistance.
   
  The Quaife differential, however, does just the opposite. It senses which wheel has the better grip, and automatically biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.
   
  In cornering, while accelerating out of a turn, the QUAIFE biases greater 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 differential also controls loss of traction when the drive 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 ATB 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 ATB differential's unique design offers maximum traction, improves handling and steering, and puts the power where it is needed most. A definite advantage, whether you are on the track or on the street.
   
  The Quaife differential is extremely strong and durable, and since it is gear-operated, it has no plates or clutches that can wear out and need costly and regular replacement. There is no maintenance required to the unit, so once installed the unit can be forgotton, apart from the better road responses.
   
  The Quaife differential is great for street driving or racing. Racers don't have to put up with locking mechanisms or spools that 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 cars towards its limits.
   
  The Quaife differential is proven in everything from SCCA Rallying to drag racing and Formula 1. It provides autocrossers with such an advantage, it has become "required" equipment for a winning effort.
