And tight bends will increase turbulence which is bad for air flow.. alot of things the manufacturers do are to do with spacing.. The hdi bay is tight enough as it is standard!
Yes but we are all arm chair engineers who just read a few books at best.
Anyone here have a fluid dynamics qualification and practices it daily who can comment?
The problem is we apply hard fast rules like 'bends are bad', but in practice everything is a compromise, and it's the sum of the compromises that engineers are BLOODY good at getting right... usually to the point that their compromise is often better than a half-arsed un-compromised solution!
Remember too that things don't just turn bad suddenly. There are a raft of efficiencies that fall off as you ask more and more from the engine and it's about dealing with the important ones first.
That pipe might be small fry vs other things even at 200bhp!
I'm not saying don't mod.
But until you incrementally modify and test to make sure mods improve things you may as well just wee in the wind!
