GM and Stanadyne took a huge gamble when they neglected to do some proper testing on their new system, but the good news is that the DS4 injection pump is actually a pretty solid and reliable unit now. Some of them passed through our doors 2-3 times or more before the customer could actually get their truck out of the driveway. We rebuilt hundreds of them under the GM warranty service period before they finally got all the bugs worked out.

The Stanadyne DS4 electronic diesel fuel injection pump has marked its place in diesel history. US Diesel Parts carries a great selection of 6.5L diesel turbo performance parts and stock parts for your 1993-2000 GM truck. “(But) don’t take anything away from George (Fury), he was an unbelievable driver, a ripper teammate, ripper guy… he was one hell of a driver. “What do they say? You weren’t cheating at all, you were just pushing boundaries,” Scott cheekily concluded. George only used it on the straights, but he gave it a hit and that would have given us a lot of power.”Ī very similar trick was allegedly employed under the bonnet of Peter Brock’s Mobil Ford Sierra in the Bathurst Shootout in 1989.Īlthough no technical breach was proven and Brock’s pole position stood, the Mobil team was later fined $5,000 for a “moral infringement of the rules”.Īs Scott points out, it’s likely no coincidence that key members of the Bluebird program had by that point transitioned to the Mobil outfit. “(In Hardies Heroes) I think it ran 1.8 or 1.9 (bar of boost), more than we’d ever done.

Scott said the combination of that and cool ambient conditions at Bathurst set the scene for Fury to record the fastest-ever touring car lap of the pre-Chase Mount Panorama circuit. You could imagine what that could do because we could run a lot more boost!”

“It went from plus 30 to maybe minus 30 in half the length of the back straight. I hit the button and I’m reading it out to Howard 25, 20, 15, 10, 10, minus 5, minus 15, minus 20! “The temperature in the intercooler chamber coming into the engine was 30 degrees, 35, whatever. “My job was to do the read-out on the straights (via radio) to Howard (in the pits) and they would record it. Fury in action during the Sandown round of the 1984 ATCC. “We filled a fire extinguisher (pointed at the intercooler) with the stuff and I was sent out with a thermometer, fundamentally… quite a bit of sophisticated gear, in the spare car. “Howard and the boys came up with this idea of running air conditioning Freon gas straight onto the intercooler,” said Scott, who recalled testing the effectiveness of the system at Sandown. However, he was not shy about another trick that he says helped Fury in his famous 1984 Hardies Heroes run at Mount Panorama. Scott also downplayed the use of the brake bias adjuster in race conditions, saying he only used it in endurance races where fuel loads varied greatly during a stint. It was only to fine-tune the boost if it wasn’t quite set perfectly.” Fury and Scott at Bathurst in 1984. “I never, George never, ever touched the ashtray in a race. You would probably wind this thing 15 times to get it to go a point of a bar. You’d go out and it might have 1.69 bar boost. “What you would do is, imagine we used 1.7 bar boost in qualifying. The little gauge in the ashtray was so finite, it was to finely tune the boost,” he continued. “The boost is adjusted by wastegate, it’s under the bonnet. However, as with many stories from the past, Scott stressed that the two devices weren’t quite the game-changers that they may appear to be.

LISTEN: Part 1 of Gary Scott on the V8 Sleuth Podcast “George and I will hold our hands on our heart and tell you, yes, it did have the ashtray, it had an adjustable boost in it and yes, our headlight switch had the adjustable brake balance,” he confessed. Scott was drafted into the Nissan team ahead of the 1983 endurance races and was co-driver of the car that George Fury drove to pole at Bathurst the following year.

In recent years Fred Gibson, a driver for the Howard Marsden-run Bluebird program who eventually took over the Nissan team, has been open about the fact some “fudging” of the rules occurred.īut is it really true that the Bluebirds had a turbo boost adjuster knob hidden in the ashtray? And that the drivers could alter the brake bias via the headlight switch?
