Landy lack­ing oomph!

Land Rover AFRICA Magazine - - TECHNICAL -

Keep up the good work with an ex­cel­lent mag­a­zine. I have a De­fender Td5 130 with 33-inch tyres on 15-inch bead locks. The first gear is too fast (or weak) and it stalls of­ten when rock crawl­ing. Although the en­gine has been remapped, I am still look­ing for more low down torque. I am con­cerned that chang­ing the diff ra­tios will af­fect my cruis­ing in high range. Will it help in the low range depart­ment to fit a vari­able turbo with all the good­ies like in­ter­cool­ers etc?

- Ivan Smuts Ed - I con­tacted our friend and Landy per­for­mance ex­pert An­thony from TorqTune to ask for ad­vice. The Td5 gen­er­ally only starts to pro­duce mean­ing­ful torque at around 2 000 rpm. Depend­ing on your gear­ing, and es­pe­cially those with large tyres, pro­vid­ing an even worse ra­tio, you can find it dif­fi­cult to get off the mark. Remap­ping does help with a lit­tle ear­lier torque (100 revs), but there is only so much you can do with a stan­dard turbo. TorqTune does a vari­able noz­zle up­grade (VNT) with an ap­pro­pri­ate remap that will pro­vide you with a whole dif­fer­ent beast. The turbo spools up much ear­lier than a stan­dard turbo and you will start to de­velop torque 300 rpm ear­lier.
