And be the loudest, flame throwing, fumes sucking into the cabin car ever! lol
Again, is this a race car or not.
Anything short of a car never seeing a plate and the road, 90% of all the things you are worrying about are irrelevant for the most part and getting way into too much detail and science behind it.
Power level you want dictates the turbo selection for the motor powering it. Tuning solution and legality will determine how much of the shit in the way under the hood can be eliminated to make room for all the turbo stuff.
Place the turbo where it has to go, space wise… then get the exhaust gasses to it some how, as efficiently as space and cash will allow.
Then the intercooler should be spec’d to be efficient enough for your goals. Not power… I am talking efficiency at pulling heat out. A drag IC isnt the same as a roll racer IC and isnt the same as a road course IC. fit that in the car then work towards charge piping fitment to the TB and the turbo.
Make a downpipe and decided what you want the exhaust to be and just make it from there.
