yeah pretty much 40lts of fuel and im 98 kg....the engine is standard with a few carb mods but nothing special....i do have some factory mazda 12APP housings,trumpet injection and late engine management which should be good for around 250HP...i also have som factory race 13BPP housings that did make over 300hp but in its current form i did manage 58 second laps at calder but im not that great a driver as im still getting used to the car.....you can brake so late in this thing its amazing.....Its just stuck to the road....and the corner speed is something quite spectacular...this seems to be what it likes----->brake really late on the straight ,smash it down 2 gears just after you have washed off some speed,then belt the go pedal straight to the floor and turn the steering wheel ever so slightly to get around the corner!its on rails!
