Quaife Differential: We got a generous discount and a lifetime guarantee.

 

Remanufactured Axle Assembly from a Del Sol V-Tec (Honda B16 outputs)
Found in many of the world's finest weight rooms. i.e. an extremely hefty setup. Weight distribution negatively effected. Cost: $90 for each axle assembly. $180 total. Very cost effective.        

Cost: $90 for axle with female spline Qty Required: 2.

Unknown cost for male spline, 1mod involute 27 teeth, Qty Required: 2.

Problems: Will require modifications to the length of the male adapter
spline including change of length, precision drilling, and adding material
to have a round area for the bearing to support. If the round area exists,
problems may occur when trying to shorten the pieces to desired/necessary
length. Additional problems (nuisances) will come up when axles are to be
lengthened. Additional problems can be caused by the massive size of the
CVs, will definitely come close to chassis.
Total Cost: ~$400

 

Drive Axle Assembly (right side) from Irvine's 2002 Formula Car

Many of the components on this set-up were purchased at Taylor Race Engineering

All other components purchased or manufactured in-house.

At least two times lighter than an eventual DelSol assembly. Est. 10-20lb difference.

Cost could be a problem. And for some strange reason, there was slop in the TRE drive assembly on the 2002 car.

From TRE site:

small tripod center - $40ea(x4=$160)

Tripod housing - $125ea(x4=$500)

14"halfshaft - $175ea(x2=$350)

Other halfshaft lengths as well - 15.75" , 18"

Total for TRE parts only = $1010

 

 

(THE Dreaded) Option #3: Modify the existing driveline from the 2002 car to work on the 2003 vehicle.
Use last year's axle assy. Disconnect inboard CVs at the 6 Socket Head Cap
Screws. Order new spline for Quaife while maintaining spline from Zexel on
the CV side. Cost: $300.
Problems: Determine where the play is coming from in the current axle assy.
Replace necessary parts as per Taylor Race specs.

 

Drivetrin de Compromise: Most of the Taylor Race engineering parts will be reused from last year's vehicle(in hopes that they will be repurchased). The diff output splines/stub-axle from the del sol will be used to connect to the inner CVs, but the outer CV joints still need splined shafts to transmit power to the hub/wheels.

We will also need to purchase half-shafts from Taylor Racing.

To the left is a picture of the axle assembly from a VW Cabriolet. Ken's Lehigh team used the assembly in a previous car.(parts are from a Pick You Part in Anaheim)

The studs will have to be replaced.

Cost is about $40
