Developing an ideal intake for a turbo setup

[Poodles]

Yep, as I said, it simply doesn't heat the air as much... People has already noticed this on several superchargers for this car that it's not as critical.

agree 100% with what AVOturboworld said

I'm just trying to correct the misconception that Superchargers don't heat up the air because "it's not connected to the exhaust manifold". Compression is what heats up the air, and the only added heat from the turbocharger is what is transferred through the wheel shaft between the hotside and coldside. While this does add some heat, it's offset by the greater adiabatic efficiency of the turbocharger.

The reason it's perceived as the superchargers not needing an intercooler as much is because some superchargers don't approach peak boost till redline, and thus in the lower rpm ranges are not producing that much boost (and thus not as much heat). Whereas a turbocharger can be producing peak boost at a much lower rpm range, which will produce more heat earlier. But also much more power earlier.

You're also ignoring the intake piping having you go right next to the exhaust side of the engine...


I never said it doesn't heat the charge and I understand basic thermodynamics.

I don't have numbers because I couldn't get everything completed yesterday, but here is where I'm at vs this:


IDK what the hell that plastic thing is with the blue water in it so I took that out


I also modified the BRZ fake vent bezel to allow air flow, but it needs some sandpaper tlc and paint. I should've just went with fog bezels with no fogs in them, but for some inexplicable reason I did not .

All that was really needed for making this for the SBD Turbo kit was a mandrel bend (Vibrant 2881 Intake Tube) and 8"-8 1/8" straight section of tubing with a 60* elbow. I went with 2.75" probably could've gone with 3". I also have not fitted an aftermarket crash bar yet, so this may need to change, and I have additional tubing to accommodate that. I also do not drive this car in the rain, so sucking water isn't as much of a concern as it should be for a daily driver.

Could always use an AEM bypass filter and/or a water repellent prefilter cover. Can't always decide when it rains

I have yet to reinstall the bumper to determine how direct the airflow will be. I'll fab up a splash guard to protect from direct airflow that will allow air to flow around filter from the left and right.
