thirstybeast Posted March 25, 2008 Share Posted March 25, 2008 Hi The engine will perform fine without an intercooler especialy if its low revs work or the cooler is likley to get packed with mud. A few people have been asking about this recently, I would say if you can fit an intercooler do it. If you cant it will still run well. I did some comparisons last year between my 200 disco with a cooler and my 200 engined 110 that dosn't have one. I put a thermo couple in the air intake manifold of each and got the following readings with outside air temp at 1 degreee C. Intercooled TDI intake manifold temp at Idle with engine warm 20 degrees. Intercooled TDI intake manifold temp at full revs with engine warm 40 degrees. non intercooled TDI intake manifold temp at idle with engine warm 56 degrees. non intercooled TDI intake manifold temp at full revs with engine warm 100 degrees. This pretty much shows the effect of an intercooler! That said my defender has yet to get a cooler fitted and pull's well fully laden on or off road with 33x12.5 R15 Hankook mud tyres.(maybe I should say pulls well for a TDI as a modern diesel will blow it away).
