..just trying to apply conventional physics to this.

After the motor goes through pushing out all of the exhaust gases in the cyclinder, it'll run from the high pressured cylinder to the lower pressured exhaust manifold. From there spooling up the turbo sending the gases down to our downpipes into the exhaust and out into the atmosphere.

Question 1:
Am I correct in what I said above?

Question 2:
Should all of these stages: Motor, Manifold, Turbo, Downpipe, Exhaust each have a lower pressure than the other? Since fluids naturally travel from high pressure to low.

Question 3:
Having a 2.5" Downpipe extending into a 3" Exhaust system. This would have a more condensed (higher pres.) system expanding into a less condensed (lower pres.) system making the exhaust gases travel more effectively. Faster at a higher volume.

Question 4:
It's not about how fast the gases move, it's more of how much gas is moved in time to make room for the rest of the gas coming... Correct?

Questions 5a,b,c & d:
a: 2.5" DP --> 3" Exhaust = Expanding into the 3" then traveling slower or faster?
b: 3" DP --> 3" Exhaust = Straight through high volume flow, best setup?
c: 3" DP --> 2.5" Exhaust = Turbulent flow - however the gases would speed up through the 2.5" exhaust faster than it was coming out of the 3" downpipe?
d: Which one would be best for a b18b running 7psi. AC does not matter.

Hope you guys can help. I just woke up and was wondering about some of this. I guess it's more of a physics question than anything else.

anybody? TTT
