For those who are interested in modifying your XR6T, here are some more options which appear endless at this stage...
Calder October 10, 2003
NIZPRO BA XR6 TURBO LETS LOOSE with an 11.73 At 125.90 mph.
Nizpro debuted their Acid Rush BA XR6 Turbo sedan at Calder Raceway on October 10, 2003 intent on some ‘shake down’ passes, noting that Nizpro staff were specifically interested in data logging to ensure that whatever changes that may be required, could be easily implemented in the future.
Vehicle modifications consist of Nizpro’s Stage One XRT300 power-up kit (custom powder coated high-flow CNC machined inlet manifold, cast alloy thermostat housing, powder coated cast alloy rocker cover, cast alloy 100mm inlet tube, K&N pod filter, cold air-box, high-flow tube and fin intercooler with lightweight aluminium end tanks, compact dry-cell Odyssey battery and battery box), along with upgraded fuel injectors, and a MoTeC M800 ECU.
For a 4-litre Ford engine that is surprisingly close to stock internally to deliver a potent 426 kilowatts through the wheels on a DynoLogic chassis dynamometer, Nizpro had also to replace the restrictive catalytic converter (in an otherwise factory exhaust system), along with a high-flow fuel pump replacing the factory item.
245mm wide Nitto road/race tyres were also fitted to an otherwise stock vehicle (including the factory turbocharger) that weighed in at 3918 pounds at an independent weight station.
Traction proved a problem, as did the diff ratio that resulted in the Falcon hitting the factory imposed 5700rpm rev limiter by Calder’s 1100-foot mark. However the Nizpro team were quite happy with the information provided by the data logging, and also drove away happy with the knowledge that they had just set the fastest ever time for a BA Falcon Turbo with a respectable 11.73 @ 125.90 mph.
Nizpro’s Simon Gishus stated that having established a base line, and become aware of all potential problems, that he will make specific modifications to ensure the vehicle meets or at least goes close to meeting its potential at the next outing.
Using the traditional Drag Racing formula (speed over mass over distance), it showed that wheel spin and hitting the rev limit had resulted in a loss of approximately 3-4 mph off the terminal speed, with the top end charge indicative of a run perfect 10.6 second pass.
