p.s. We lost focus of the original idea for this thread.
Where are the dyno numbers off OP's custom intake?

If there's 5hp gain I would be impressed... The bigger draw and gain I see is the noise factor as the factory box is built to keep it quiet where round tubing will act as megaphones for the turbo suck whistle.

Unless the filter is completely submerged, this notion that engines are sucking enough water outta the air to hydrolock needs to die.

Are you speaking from experience or theory? I've taken mine from Seattle (30°-80° F averages throughout the year) to Hollywood (90° average in summer) to Las Vegas (100+ ° F average in summer) for the past 3 years...stop armchair engineering, bro lol

I also agree that you shouldn't worry about water issues if a sock is used. My supercharged Z3M has the air filter in the brake duct facing the elements, and I haven't had issues using the sock. It's been through car washes and heavy rain downfall on the highway.

In regards of power, changing the intakes shouldn't make much of a difference… if any. The way an engine makes more power with turbo is different than NA. Raising the boost pressure will allow more air into the cylinder to produce more power. A free flow intake system helps more on NA.
When you are pushing the turbos to its limit is when you’ll see a power increase from changing the intake. Some people are at the point, but not many. The main purpose I would change the intake, other than a cooler sound, would be to increase the size of the intercoolers. The power potential of adding 2 more inches of intercooling is far greater than changing the intake. There’s a reason why you’ll find many companies spending R&D for downpipes for our cars instead of intakes. Performance gains are easily proven with downpipes oppose to intakes on a turbo application. |

Socks were a must for me. We rarely get rain here but I didn't want to have to worry when we do. Never had an issue. Sometimes I just wipe them down with a paper towel if they get dirty. It's incredible how clean they keep the filter. Last edited by mirob; 01-23-2018 at 02:28 PM.. |

@M5James, Send me closer multiple angles of the pieces, aswell as sensor bung requirements. I'm going to discuss with my fab guy..... Here's an example of his work on piping... everything built from scratch! This was prior to smoothing, heat treated, and chromed. |
