It's admittedly been a while since I took Physics, but doesn't increasing the diameter of a pipe decrease flow velocity, all else held equal?
Yes...but all else is not equal here...this is why I also said that "that's the easy explanation" and "to a point".

What I can say is what I've done in real life experiences and that the dyno charts speak for themselves. We can talk theory all day long, but the dyno doesn't lie. I have worked with individuals who do these things for a living and have learned from them along with my own trials and testing. No I don't believe that changing to something like 5" diameter piping would be better, but with what PRL has done, I believe, should be an improvement. Eventually we'll see a back to back dyno to prove or disprove these products. With what I've learned over the years and what I see in the design of these components from PRL, I'd believe that they should be an improvement over stock...for $265 shipped I'm taking a chance...its an inexpensive trial.

More power potential...same for the turbo inlet tube...add all together with other breathing mods and it usually tends to make more power. Increasing air velocities and lowering flow restrictions. Think about it this way...the fastest way between two points is a straight line...the more gradual the bends and the larger the diameter (to a point) tends to increase the flow of air...thus making more power...that's the quick and easy explanation.

I went through this process several years ago on my S2000 and it proved to be a very worthwhile change. Here is a before and after dyno of before the piping changes and after (Red and Blue). Black denotes the switch to E85 (E65 at the time of the dyno). https://www.s2ki.com/forums/s2000-f...-rotrex-c38-92-a-1086804/page14/#post24378856

curious to hear your guys thoughts on this after getting it. I have the prl intercooler so i will most likely get it but want to hear others experience on it first.

It's live on BTurismo.com! Might have to get this and an intake at the same time-

You have to put in account for pressure, going too large, is bad yes, at stock pressure or boost. But a legitimate small increase in diameter of pipe allows for higher pressure, safely, which in turn equals more flow. On a stock setup, it won't be much in creating performance, maybe 5hp or around that (is my guess), but at higher boost pressure, stock piping will become a "pinch point" or "bottleneck" in the system, which can cause more strain and stress on parts and hinder the motor power output. Opening up the pipes just right gets rid of the bottleneck and the stress on parts, and can have a very effective increase in power. For example: A car makes 1000hp at the crank with the turbo charge piping being 3" in inside diameter. You increase the diameter to 3.5",( lets say this is maximum point of power, meaning any larger will have the same affect as 3.5" and may or may not hinder the system due to weight, and or too large to gain the correct boost / pressure level the system is needed). The 3.5" large pipe will increase power by a larger percentage than the previous 3" pipe. Figuratively speaking in suggestive numbers, the 3.5" pipe now has the car pushing 1100 hp at the crank, ( also figuratively, could be more could be less, but never less than 3" piping). If I remember correctly, this is how much of that math plays out and @PRL Motorsports will most definitely know this mechanical aspect too. I've recently gotten out of Mechanical Engineering with a side of aerodynamics btw :thumbsup:

Why is a charge tube too large of a diameter a bad thing?

Can confirm i got shipment notification! Although i dont plan on installing anytime soon since i am still waiting for inlet pipe/intercooler/ maybe upgraded turbo :oops:

I just received a shipping notification for the charge pipes & will deliver Monday. Won't be installing until the HVIS arrives to get it all done at once. Hopefully the Ti crossover & inlet pipe will be done before the HVIS arrives.
