Have just got home from Sydney. Car is just great, no difference from LPG to Petrol.(except costs) APS knew I wanted to make more power one day and fitted two regulators to the car. Just to give you an idea of the potential here, one of these regulators on an LS1 is known to flow sufficient fuel for 200+ rwkw so I have two!!! :yummy: You can barely see the injectors (they are under the manifold) check out the pics: Boot Install (very neat) I got the 60L useable tank, apparently this is the biggest available for the BA/BF. Hidden injector. 2 regulators (1 is good for 200rwkw!) Fuel switch Regarding fule consumption, According to ECU between North Richmond and Bathurst was as follows: (keep in mind that I accidentally forgot to change from manual on both legs and therefore drove in third for quite a while.) Time 1hr 31 minutes Ave speed 80k Distance 136.5 Average fuel consumption 11.1l/100k's The car used 16.69l of LPG for the trip. 16.69L divided by 136.5 (trip distance) is 0.1223 so 0.1223L is average fuel per kilometer. Multiply 1.223 by 100 and that gives 12.227 L/100 average over the trip. Keep in mind on this leg I was overtaking and doing lots of uphill driving. Next leg. Bathurst to Mudgee via Sofala (More hills and corners): ECU (reset when leaving Bx) says: Trip time 1hour 25 minutes Avrage speed 89k Distance 116k Average fuel consumption 10.7L/100k Actual use: 15.137L divided by the distance 116k is 0.13049 per kilometer ( the ambient temp is over 30 degree's celcius at this stage) so that's 13.0494L/100k's The last leg I cant really measure because I accidentally drove on petrol for some of the distance. Go the LPG! If you can have power and cheap motoring, why not have both.?
