Tomcat Nev Posted April 12, 2006 Share Posted April 12, 2006 Does any one have any figures for the maximum torque that the ZF HP22 or later HP24 can handle?? Cheers Nev Quote Link to comment Share on other sites More sharing options...
will_warne Posted April 12, 2006 Share Posted April 12, 2006 The figures I've heard are 280 lb/ft and 360 lb/ft respectivly. Quote Link to comment Share on other sites More sharing options...
steffUK Posted April 12, 2006 Share Posted April 12, 2006 How can i convert lb/ft into Nm ? cheers Steff Quote Link to comment Share on other sites More sharing options...
Astro_Al Posted April 12, 2006 Share Posted April 12, 2006 1 ft lb = 1.35 Nm (ish) Al. P.S. Just to be pedantic, for the record it's lbft, not lb / ft which means pounds PER foot and is not a torque. It's funny that people always write Nm correctly (not N/m), but often put lb/ft. Quote Link to comment Share on other sites More sharing options...

will_warne Posted April 12, 2006 Share Posted April 12, 2006 Sorry Al, your totally right. Steff, that gives a figure of, about, 380 Nm and 490 Nm Quote Link to comment Share on other sites More sharing options...
Astro_Al Posted April 12, 2006 Share Posted April 12, 2006 Sorry Al, your totally right. Steff, that gives a figure of, about, 380 Nm and 490 Nm Hey, its cool - I do it myself when I'm not thinking too hard. I don't know why but it seems to be kind of the accepted way of writing it... Cheers, Al. Quote Link to comment Share on other sites More sharing options...
Tomcat Nev Posted April 12, 2006 Author Share Posted April 12, 2006 Thanks, thats just what i need. It means that a 24 internaled 22 (if there was such a word!) will take a chevy................ Nev Quote Link to comment Share on other sites More sharing options...

It's funny that people always write Nm correctly (not N/m), but often put lb/ft. Well I usually put lb ft not lbft or lb/ft so what do you make of that then? Nm are a nasty foreign invention that should be banned along with kilowobbles and driving on the wrong side of the road bah humbug ;) Quote Link to comment Share on other sites More sharing options...

Nev Yes, that's what I've got and as long as you keep it cool and aren't tuning it madly it should be OK. You can still make a 24 spec box go bang (ask Lara ) Quote Link to comment Share on other sites More sharing options...

Nev If it's going behind a chevy, why not a th350/400 or a built 700r4, if you are wanting to keep a land rover transfer case advanced adapters do conversions from the above to lt230.

pugwash Posted April 13, 2006 Share Posted April 13, 2006 great link, but do you have any idea whinch part would do the job? Quote Link to comment Share on other sites More sharing options...
Lara Posted April 13, 2006 Share Posted April 13, 2006 Hi there, I think you will find just like me that an HP22/4 will not take 360ftlb / 490Nm torque for very long. My 90 has exactly 490NM and has eaten 5 or 6, 22/4s and at least as many torque converters (even specially uprated ones) I now have a specially uprated HP24 and a special 12" torque converter to cope with the power. Hopefully that setup will last. If doing it again I would 1000% deffinately fit a Yank box, probably a TH700 Lara. Quote Link to comment Share on other sites More sharing options...
Astro_Al Posted April 13, 2006 Share Posted April 13, 2006 Yeah, what he said. Those ratings look pretty marginal for most Chevy engines. As he says, why not run a box designed for more torque? I'm currently goingthrough the exact same nightmare with manual boxes and chevys... Seem to be settling on the NV4500 as the alternatives are either marginal on torque capacity or too long. Bogmonster - try to be more contraversial, start using ft lbs... Al. Quote Link to comment Share on other sites More sharing options...
Tomcat Nev Posted April 13, 2006 Author Share Posted April 13, 2006 Hmmm, i wanted to keep the 4 speed box if possible but having looked at the cost of uprating the HP22 to HP24 and then changing to LT230 i can buy a complete VHD TH350 with manual shift etc that will last all day long. Therefore sticking a LT230 on the back of a TH350 is what i think i shall do, i checked Advanced Adaptors out and they seem to do everything except a TH350 to LT230. Marks4x4 in Australia do a TH400 to LT230 conversion but i have no idea whether this can be modified or even if it fits directly on a TH350. Nev P.S. i might have some RV8 4.6 tuning parts for sale soon...... includind Twin Plenum set up. Quote Link to comment Share on other sites More sharing options...

But that said i carn't find it on there website either. Worth giving them a call to find out if they still sell them, Quote Link to comment Share on other sites More sharing options...
