Hi Guys,
With gas, you need around 150cfm of air to make each 100bhp, (this is very much a generalisation, so please don't flame me )
Is there a similar generalised formula for the PD diesel engine?
I'm looking at compressor maps and specs and trying to get my head around how to get a close guestimate on how much air / what size turbo I need to hit my targets.
I understand that compressor efficiency etc all has to be factored in, but I need somwhere to start from!
Many thanks,
Rich
