Thought I would add some background details to Roberts report...
As you probably all know the Australian Top Doorslammer class regs are more liberal in the engine department than ProMod, allowing Top Alcohol type combination including screw-blowers. However the cars are limited in blower over-drive and carry a hefty 2700 lb minimum wieght.
That is where Willowbank Raceway decided to make things interesting, setting up a run-what-ya-brung no-limit match race between the 2 quickest cars in the country, Victor Bray vs Peter Gratz.
While both Gratz & Bray campaign carbon-fibre '57 Chevy bodies over a Murray Andersen double-rail chassis, there are _major_ differences in their team operations.
Victor Bray, a national icon in Australian motorsport, runs a smart 3-car team (2x Doorslammer + 1x TAFC) which enjoys major backing from Castrol, allowing them the resources to race (and win!) at tracks from coast to coast. Victor also has an impressive inventory of modern BAE6 engines, and has a very close working relationship with Norm Drazy who supplies his PSI blowers.
In relation to his very seasoned rival, Peter "Yahoo!" Gratz is a relative newcomer to the sport and his Valvoline Chev is run on a shoe-string sportsman budget. His step up this season from a 14-71 to Whipple screw-blower has gained the team performance, but the price has been heavy in increased maintenance to their one-and-only engine. A dicey situation for a team that does not have deep pockets!!
The third component in this match race was of course the legendary track conditions at Willowbank Raceway. During the winter months in South Queensland, a chill creeps into the normally balmy weather and the air conditions for motor-sport are just about unbelievable. In fact if you have never been to a race such as the famous ANDRA WinterNationals, you may _not_ believe that the corrected altitude at this racetrack has been known to hit MINUS 500 feet!!! These condition combined with world class track prep is what makes this the home of some awfully stout track records <grin>.
Robert has already fed you the results, but I thought you might like to see the actual run numbers (courtesy of Dennis Syrmis & Willowbank Raceway) from the match race:

(Note: Debris from Gratz's car caused the erroneous speed!)
The aftermath of that final pass was that although Gratz ran his person best he also lost an engine in the lights. In Dennis Syrmis words, " the sky lit up like a roman candle as the engine exploded, nitro Funny Car style. The car crossed lanes, causing Bray to brake heavily and then hit the Armco hard, eventually coming to a halt at the end of the asphalt ".
Both drivers were un-hurt and Victors car is repairable. However Gratz could only salvage a few spare parts left out of the pile of junk remaining from what was his only engine. With Scotty Cannon arriving down-under for the USA vs. AUS tour in just under 8 weeks, it looks unlikely Peter will be racing unless he can find some serious support....
