Saviem:
Evening all, late night, and not in good humour!!!
So Anorak, Im inclined to agree with your statement about Volvo figures.
I have an Italian spec sheet 1975, showing 360hp,
A French one showing 330hp DIN. 1975
and an early UK one showing 315hp!!!
Is this a Royal Flush!!!
Im away to the Bollinger…its too complicated for this old Farmer…oh my 75 UK one, it shows 330BS hp!!!
Far beyond me…could it be horses for courses■■?
But a bl…y fine lorry to drive…I still think , one of the best ever…stuff you Scania men every day…if only you had had a proper gearbox…but you did not!!!
Im going its cold in this old barn, nd the Bollinger beckons! Bon Nuit, Cheerio for now.
Bonne année Monsieur Saviem. There is a post somewhere from our resident F89 expert, The Crow, that states that the Italian F89 had a different injection pump, which gave it the power to beat the 352bhp minimum for Italy. Elsewhere, someone else has posted that the 340bhp Magirus V12 was rated at 360bhp for that market. I read somewhere, ages ago, that even DAF, with its comparatively small (11.6 litre) engine, had a 350bhp 2800 for Italy.
Regarding the Volvo power figures, maybe 315bhp was BSAu141 net and 330bhp was gross (DIN and BS). This would make sense. It would not explain the 330 SAE figure, though: that should have been 350+, for the same engine.
Another factor is that there are tolerances on engines and even fuel. Even the ambient air temperature and pressure will be controlled within limits, when the engines are tested. If the DIN, BSAu and SAE tests are conducted on different days, in different locations and on different individual engines, the results will have some variation. The quoted figures are just what a particular engine achieved on a single test. Plus, the figures do not take into account what happens when Mr. Greedypower, the fitter, gets his spanners on the injection pump and turbocharger!
