Hi guys,
Thanks a lot to all those that responded. In particular, Dozer, Floyd, Bob Y
Ross and Bob. This is the first (
well second now)time on explore OZ and I really appreciated the
feedback. I have the update model which has the 265/75 x 16 BFG A/T currently and for some funny reason the final drive on the 1HDT is 0.88 cf to 0.81 for say the 1HZ according to my manual (Max Ellery pub'). The "low" final drive makes 200rpm difference at 100kmh.
The reason behind looking for a o/d unit, is in looking for the vehicle, numerous others were looked at and they all seemed to suffer from copious amounts of blowby which I put down to too high revs typically at touring speeds, especially for the turbo diesel. I really appreciated the comments re BHP and torque cf to revs and I will probably go the rubber option as i too were concerned about reliability issues of the o/d unit on the proven toyota product (which incidentally is only supposed to be used at speeds of 80kmh and above in 4 or 5th.
I spoke to my diesel mechanic about high revving diesels and even though the 1hdt is an overhead cam he still thought that 2800rpm on the Hume was too high for the 4.2 litre. Maybe 3litre turbo diesels need more revs, but all the auto's sit on about 2100 - 2300 with a torque convertor though.
Toyota's
unofficial comment is the high revs for 5th is that it is made as a 4wd for low ratio and must be useable there????
Anyway thanks a lot for all your comments.
