thats an interesting idea, i am not sure but i think fitting a turbo would be cheaper and possibly more effective however, i drive a gq 2.8td and i can understand a turbo doesnt suit everyone, ie i would imagine a supercharger runninng on a belt is more reliable than a red hot turbine spinning around, have you known anyone to fit a s/c to patrol, let us know how it goes, especially interested if you get it on a dyno.

Colin,
I have a 4.2 litre Cruiser with a Sprintex supercharger fitted. The improvement in power from standard is remarkable. I recently towed a Coromal Magnum 440 camper trailer across the Great Central road from Perth to Yulara, up to Darwin and then on to the top of Queensland before leaving it in Mossman and doing the Cape in tents. The economy has suffered a bit, but it doesn't seem to change whether you tow or have the aircon running. Overtaking no longer requires me to phone ahead a week in advance and make a reservation. It's just a matter of put the foot down and hang on. The greatest advantage is that you are getting your boost all the way from idle and do not need to have the revs up a little in order to get the turbo spinning. One disadvantage is that the belt spacer moves the fan forward about 25mm and I paaid the price for not blinding my radiator when crossing the Goyder River on the way back from Nhulunbuy, but that's another story altogether. Do i recommend them as a power booster. bleep yeah!
