streaky Posted October 8, 2007 Share Posted October 8, 2007 Wierd question..... My Disco has a 4.6efi hot wire now and yet I'm not so chuffed at the performance or it's even worse fuel consumption. After some trouble shooting my workshop has had the truck weighed and came up with a figure of 450kg over the top of a standard Discovery Series I. 98' model. The increase in weight consists of ARB Bull bar 50kg with Ramsey winch 30kg, two optima batteries 20 kg, Wolf rims shod with 265/75 R16' BFG AT's KG????, two stainless steel underbody fuel tanks weighing 60kg combined, Front runner roofrack 30kg approx, rear load draws 25kg approx. Thats a breif list of the weighty items accumilating approx 270kg.... I can't yet see where the rest of the figure has come from but will find out when I return to UAE next week. I went to visit the boys at V8 Developements last week with JW, they seem to think that 450kg would slow the truck down in terms of accelleration and general grunt but I'm still not 100% convinced it would effect the fuel consumption that much. I was getting approx 250-270km to the tank full (90lt) this seems really bad to me even with a truck weighing 450kg more than standard. V8' D's had some great inputs about enough air getting into the plenum. I currently run a Mantec snorkel and regular OEM airfilter. The K&N's let in far too much powder sand for my liking. Assuming the engine is tuned to perfection with a Kent 268 cam, vernier pully arrangement and a Mark Adams 4.6 Tornado chip.... do we think I'm over reacting to my poor fuel ecconomy or should this be expected? Thanks. Quote Link to comment Share on other sites More sharing options...
