Aps Phase III Passes

[Guest WHITEXR6T]

Good work getting the phase 3 evolution happening

This question might be a bit off topic, but here goes. Dont shoot me down for not knowing this please.

Is your 11 second APS ute equiped with phase 3 ? or phase 2 ?

Most of the 11 second passes in the ute were with the phase III system, though the current spec is PHASEIII1/2, still missing a few parts to complete PHASE IV. :banghead:

It is my understanding that all cars eligible for the top speed run as mentioned in the other thread are "production cars", and as such are fully road legal? Did you have any issues getting an engineers report for your car, (particularly with the taller diff ratio and the added strain this places on the drivetrain, ) in order to prove eligibility for this event?

Well the diff ratio change wont have any impact on the engineers report, I will organise a report for my xr6t next week wont be a problem. I doubt that a ratio change from 3.46 to 1 to 3.23 to 1 would be much cause for concern.

The main point here is you cant get an engineers report without proving continued compliance to ADR 79/00, this is by far the most expensive part of the engineers report and is what we provide to APS customers free of charge.

Umm, if the gearbox ratio doesn't change, the wheel diameter is the same but the diff ratio changes, where does the extra stress on propshaft and gearbox go as the vehicle accelerates at a slower rate and therefore is closer to brake torque ?

To exadurate, a car with a 10:1 diff ratio, puts less stress through the box and propshaft than the same car with 1:1 diff ratio ?

Given the previously mentioned rules regarding the requirement to ensure that nothing in the driveline is overstressed, and that the ratio change will be further increasing this, I will be interested in how the engineer will sign off on this one.

No problem,

I will let you know when the report is finalised, though just one point we dont intend to sell 3.23 to 1 diff ratios in the phase III system so this entire issue is actually irrelevant.

We ran 3.23 to 1 gears in the speed test as we needed the gearing to avoid making an $8000 gearbox swap. I do not like the truck like shift quality of the T56 6 speed so the diff ratio swap filled the void.

Peter, thanks for clearing up the issue of selling the kit with the 3.23 diff, I think WBT56's point was that the car should be registerable in the form that it ran the test, that's why I was asking.

I dont know why this became an issue in the first place as we have never stated or intended that a diff ratio change was part of the PHASE III system.

As a matter of interest I dont see any reason why the vehicle could not be registered with a 3.23 to 1 ratio.

In years gone past we have gained approval as a second manufacturer from F.O.R.S with a number of optional diff ratios and I dont see that this car (xr6t) would be treated any differently

It seems to me that some are under the false impression that the APS car was part of the magazine's major road test, whilst this is partially correct the APS car was being tested for another feature article.

I would like to say more though its not possible as a professional courtesy to the magazine.

Only that the drivetrain stress woudl be more than what the components are rated to.

And yep, sorry, I was one under that impression, and completely understand not being able to mention more - can't wait to buy and read, must have been a hoot !!

Thanks for your reply, glad that you understand now what the speed testing was about.

Its amazing though how some bag the T5, you would almost think that they had a vested interest in doing so ........I will say no more .......just read between the lines!!!
