911 RSR 3.8L NA | G50 5 Speed

We fit this 911 race car with a 3.8L 964 based RSR engine, and coupled it to a 1989 G50 transaxle.

The gearbox has all the tricks, tall 2.8 ratio first gear mainshaft set with close ratio gears straight thru 5th gear. 
We set the G-50 up with a Quaife torque biasing differential and our billet side cover.

This is just the start of our project build sheet, see the detail in the photos and read the description of parts & service related to getting it done.

These services shown here are performed daily at PATRICK MOTORSPORTS, and the products we use are always available for purchase with same day shipping! Call or email us for your needs today.

Palme - FB test

Now it was time to run the car in the real world at the race track, we were
able to fit in 2 track days at Firebird Raceway. We spent one day on the EAST track (4 nice straights with good braking zones), and one day at the WEST track (featuring 1 long straight, but mainly consisting of transitioning turns that allow you to practice your trail braking skills, along with 2 great carousels).

We like the Firebird WEST track for testing because it lets you hang out the car in a variety of corners. This is great for getting the 911 right to the ragged edge, this is the only way to help you dial in the car!

Palme-G-50-trans-detail

G50 Transaxle - Quaife Close Ratio Gears / ATB Differential. 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 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, 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.

Here we are spinning up the flywheel & clutch package for the 1987 1989 G-50 transmission. We start with balancing our 240mm lightweight flywheel to less than 0.1 oz per inch from center using our CWT 5000 digital balancer system. We then add the G-50 aluminum pressure plate, starter ring gear and complete the assembly.
