Fiat Abarth 131 - Gearbox ratio difference
Posted: February 24th, 2009, 2:50 am
I have put together two speed vs. rpm graphs.
One shows standard gear ratios of a 131 and one showing close ratio gearbox as used in 131 Abarth.
Both calculations were made based on a 7:43 diff.
Look, what a difference a competition gearbox can make!
It looks like making the engine 180+ bhp is just the beginning of hard decisions and spending ... it really requires more! The diff and gearbox seem to be key.
