As the initial dyno tests are concluded our Project Holden V8 comes off the dyno. The stock 5 litre EFI engine is found to be in great mechanical shape making 296 BHP when tested with Pacemaker 1 3/4" primary header size Pacemaker Tri-Y extractors.
Our donor engine (Holden 5litre EFI V8) is given a wash and an oil change prior to mounting it on the engine dyno. After installing the engine on the dyno a fresh load of mineral based "Martini" 20w-50w oil is added with a new GM filter.
Take a Holden EFI V8 cutout engine out of a VN-VS Commodore. Run it as is on the engine dyno to baseline it and begin to make changes to evaluate the costs versus the performance gains. We find many enthusiasts make changes that are not always cost effective.
