naci Posted May 28, 2009 Share Posted May 28, 2009 Dear All, I have two 3,9 efi V8's first one is on 1996 Disco 1 with auto box & 1:22 tc gearing - runnng 255/65/16 road tires - having RP4 cam second one is on 110 defender, with ltt 77 manual gearbox & 1:22 tc gearing - running 235/85/16 bfg - having standart cam the only difference I can feel btw those, the disco gets revved a bit more slowly than the defender I am now looking for a camshaft for my defender other than RP4 which would give me some good low range torque... any suggestions please??? thanks and regards naci Quote Link to comment Share on other sites More sharing options...
Fern Posted May 31, 2009 Share Posted May 31, 2009 My knowledge of cams: 3.9 standad cam gives good torque at the low range ~@2000Rpm 4.0 cam will give the same troque value but ~@4000Rpm. Quote Link to comment Share on other sites More sharing options...

I am glad someboyf finally replied , thanks very much... actually I am still looking for a after market camshaft which is specifically designed for giving such torque at lower revs... hence I am still waiting to hear from the other forum members who has some previous experience of such camshafts with respect to its maker and model of such camshafts... thanks in advance naci Quote Link to comment Share on other sites More sharing options...
Traco Posted June 2, 2009 Share Posted June 2, 2009 You could try the new Real Steel Cyclone cam or the Piper Torquemaster. Both are high torque cams for use in 3.9 - 4.6 engines and can be used with auto boxes with good idle. The Cyclone gives an extra 27ftlb. Another cam is the Crower 50229 from V8 Tuner.

cipx2 Posted June 2, 2009 Share Posted June 2, 2009 I remember some discussions on the subject on the discoweb.org LR forum in the US. A quick search showed some threads on the subject, including some reports about the above mentioned 50229, so I suggest to have a look and maybe post a question there.
