TURBO TAXI AND AUTOTRAD DRIFTER COILS
PULLED FROM THE LATEST COPY OF STREET MACHINE.
On Day One the Taxi didn’t look like it was going to play the game at all with a 12.11 and a 12.3 at 118mph, but closing up the plug gaps to a mere 8-thou meant the Taxi had enough spark to run an 11.54 at 121.99mph. What a relief!
The crazy thing is that the 1900kg Falcon clearly had more in it because the ignition was still breaking down, so we packed up the gear and headed to Warwick via the scenic route before hitting the rural 1/8mile the next day.
Despite the tight plug gap the Taxi decided it really didn’t want to play at Warwick and the best we could manage was a 7.86 at 91mph; four-tenths slower than our half-track speed on Day One. So we hit the road back to Willowbank via Toowoomba and hoped for at least one clean pass on Day Three.
To kick things off for the last day Scotty decided to do a pass on the Falken street tyres and without even trying it ran a 13.3 at 109.6mph. Then he bolted on the 255 drag radials and Taxi decided to throw a tantrum. Run after run the ignition system broke down every time and combined with some serious heat soak, thanks to the thermometer cresting 30 degrees, the best we saw was a 12.49 at 115mph. Arrrrgh!
Clearly our next job is to sort out the ignition system. We’ve already added a set of Autotrad Drifter coils post DC Weekend and while they’ve definitely made a big improvement to driveability, they’re still marginal at 16psi. To run that 10-second pass we need to crank the boost up to 20psi and that’s just going to kill the spark again, but we reckon there’s a solution on the horizon.
So stay tuned for the next instalment of the Turbo Taxi.
