FK8 Inlet Pipes

[SpicyPIXEL]

Rather than start a new thread - any inlet pipe "better" than the other?
Eventuri vs Rampage vs PRL - Price doesn't matter to me

I'm leaning towards Eventuri or Rampage because of the 1-piece design

Edit: Thanks BrokeCTROwner for the correction - Eventuri IS a 2-piece design

If you want rampage look but custom design/titanium coloring...innovatig. and about $250 less

I would think Eventuri would perform better in the long run cause of the carbon pipe that "should" have less heat retention no?

Eventuri is actually 2 piece

There are some advantages to the two piece design . With that said, the Eventuri has proven gains by keeping IAT down.

I went PRL because of this 2 piece

IAT is important but so is flow + efficiency. The 2 piece designs aren't as smooth as the one piece designs like Rampage and Eventuri*

That's a good point.

Loss (minor loss coefficient) from unions/couplers. A coupler would have about the same loss as welded joint. Therefore, we should include welded joints.

	Eventuri	Rampage	PRL
Unions and Couplers	1 coupler at turbo	6 welds	5 = 4 welds, 1 coupler

Friction factor is another thing to consider. As the internal surface roughness increases, so does the friction factor and turbulence. Metal is smoother than composite.

Since the diameter of these inlet pipes is so large, I doubt the loss from coupling and surface is significant. That said, without actual measurements and calculations, this is just speculation/opinion.

The transition on prl two pieces inlet pipe is smooth . The silicone coupler is not straight coupler , difficult to explain but I will find a picture and posted

Looking for some help, does anyone know how I can source the hardware that usually comes with the eventuri inlet?
Mainly the turbo flange and coupler that go to the turbo?

You’re gonna have to contact eventuri directly for that. Or maybe hit up a vender and see if they can get it for you

I'm interested in the PRL inlet pipe. do I need a tune to run this? my only mod so far is the PRL HVI

Nope


Just make sure (Especially if you don't have datalogging abilities) that you've got the inlet pipe -> turbo gasket 100% sealed and the bolts torqued to spec as you can get small vaccum leaks if you're not careful with the reinstall.

Is there any significant difference in heat retention in regards to the tubular titanium options vs the casting on the PRL vs the composite of the eventuri?

Don't castings hold more heat than the tubular options because of cross section and structure?

I think a the end of the day any of these choices would be fine. The difference in HP is probably negligible.

But if you already have a PRL HVI or eventuri intake, it probably easier to get the same brand.

I got the prl inlet to work with the eventuri intake, but it took some work.
