Manual Upgrade

[Guest ante]

Just a note on quick shifts, the actual travel of the gear stick is shorter due to a higher pivot point so first to second can just be flicked in with almost half the travel as a standed shifter, your still left will some of the strange things T-5s do when your in the mood.

thanks ante - heard you the first time heheheh.

Love your work bcl. Looks as though your headed for an upgrade. Just checked aps website to compare their torque figures with the TKO's. The TKO looks as though it could only handle the Phase I option. And the TKO II can only handle Phase I and Phase II. Phase II if your feeling adventurous. Looks like we're getting somewhere. Hopefully we will get there b4 our gearboxes crunch out!

Interesting article in August Motor, CAPA supercharged a XR8, 400kwfw (310 kwrw), with the Tremec gearbox, only mod was the exhaust and chip 'fooler' Oh. and supercharger (silly me!!) :D

Cost $6900, and CAPA are confident the XR8 drive train can handle the upgrade.

How much for the Tremec gearbox/XR8 drive train (minus trade-in)?

Chief,

I haven't contacted CAPA, so I don't know where they are sourcing the 6 speed box from.... I.e locally or O/S.

Check out the following link to a U.S site of a company called SMH,as it may be something like what is being offered.... modified 5 & 6 speed versions of the Tremec.

How the ratios used would work with our car, rather than a V8, I can't say.

The box CAPA offer is sourced locally. They are VERY strong, you don't have to cut the car, and they really improve the XR6T.

All the Tremec detail on the SHM website is a direct cut and paste of the Tremec brochure. 98% of everything else on offer appears to be straight out of the Ford US motorsport catalogue.

they mention the TKO which is also on the CAPA website no price as of yet. I suppose we will have to wait until a bit more R&D is done.

TKO will not fit without seriously altering driveline angles, among other things. R&D is done. The chiptorque car has been running around with a T56 in it for many months now. The box is already proven in many high powered V8 cars in Australia, and fitment is easy.

If you check out the specs on the TR-3650, as used in the V8's,

As for what the XR6T uses, I’d like to know. The Tremec site mentions the T-5, but my understanding is that the T-5 is Australian made... BUT that box has torque capacity of only 407 N-m.  So what do we have, and what is the torque capacity?

The TR3650 has an integral bellhousing and so won't fit the I6.

The T5 we use is not listed on the Tremec website. Tremec manufacture the vast percentage of the hard parts for this box. It is assembled locally. The internals are specified as "T5Z" and they carry a torque rating of 447Nm.

Thanks wbt56.

So T-5 and T5 are not the same, although some specs are similar. OK.

If the T5Z is rated at 447 NM and we have a base 450NM motor we are definitely at the limit.

Any information garatefully accepted. I'd like more info on the T56, and what APS are looking into.

regards,

Brian

The internals of the box are the same as the Mustang Cobra R. Ratios are: 2.97, 2.07, 1.43, 1.0, 0.8, 0.62. First is essentially the same as the T5. Second and Third are slightly lower, and fifth is closer. Fitment is relatively straightforward. The same flywheel, pressure plate style, crossmember, mount, tailshaft, etc, are retained. Driveline angle is identical to factory, and the BCD rubber coupling is retained, leaving no avenue for NVH issues to arise. Stick comes through the same hole in the floor, same boot, console boot, etc, therefore interior remains unchanged, except for the extra gate on the pattern on the knob. The mustang T56 does not have the rattle issues that seem to plague the TR3650 used in the V8. Hope this helps.

Ben.

Thanks for the info WBT56. that's the kind of stuff that we need to hear. Appreciated.

Sorry about the late post guys but FWIW, the T56 conversion that we are running in the ChipTorque car was done at Mal Wood in Warwick and should be available from us on the Gold Coast or our Sydney Distributor in due course but in the mean time, contact Mal Wood Auto directly on 07 4661 3548. It is a super strong box with great ratios (unlike the Expensive Daewoo version) and will hold all the torque that we expect to throw at it.

Lok11,

Any idea on price? Even a ball park figure would be appreciated.
