Trickyx, when my 4.6L TR8 was putting out somewhat less than the 280BHP it had produced on the dyno, it could use up to 24L/100Km when really thrashed. On a Sydney Brisbane run, on one stretch it used only 12.9L/100 for a tank full. It had an overheating problem in heavy traffic, on 30-C days.
Since then it has had some performance modifications, & is producing over 320BHP. After the modifications, but before propper tuning, just some mucking with the laptop, I did 2,900Km, Brisbane to Wollongong & back with about 30% city running. My overall consumption was 10.1L/100Km. The overheating was so much reduced I could use the air conditioning in city traffic on a 27-C day.
From a different angle, I have raced a number of cars around Bathurst including F1 V8 Brabham Repco, F11 Brabham Ford [1100cc], FJ Lotus 20 Ford 1100cc, Morgan +4 2.0L, Holden Monaro, Ford GT HO, & even a Hillman Imp, among others.
They all but the Imp gave 7 miles/gallon
[:D] Obviously we were better drivers that that rally mob. [}:)]
I know this sounds ridiculous, but that's what they used. If you would like to cover the expenses, I'd happily run the 4.6L V8 in a race there, to find out how it compares for you. [:D]
