Dinan turbo inlet installed; w/ sound clips
Installed the Dinan turbo inlet today and thought I'd write a quick review. Install took about 30 minutes. I was worried it was going to be a pain to disconnect the Evap hoses, PCV valve, turbo clip etc. but it was actually pretty easy. It was kind of a pain to take off the inlet O-Ring and swap it over but pretty sure I got everything correct.
I already had the full Armaspeed carbon fiber intake, so this was just adding the Dinan carbon fiber turbo inlet. Performance wise, can't really tell any gains. Sound wise, the Armaspeed intake already made it much louder. The turbo inlet maybe added a slight bit of noise. The one change I noticed is when I let off the throttle, there's kind of a whirling/whining noise which wasn't there before. Anyone else notice this? Here are a couple clips I made. One from in the car (with windows closed) and the other is giving some revs in neutral coasting by around 3mph. https://www.youtube.com/shorts/Pr6SnwPStf0 https://www.youtube.com/shorts/WSBx_yklj90 |

Looks good. The whirring sound you described might be referring to the spool up/spool down sound from the turbo. If so, that is normal.

Thanks everyone! I actually sent my video to a tech at Dinan; he responded that the noise is completely normal and that it's the diverter valve opening and closing.

I ended up removing the Dinan turbo inlet and just going to run the Armaspeed intake without it. While the Armaspeed sounds amazing with the turbo spool, blowoff valve type noises, I wasn't a fan of the noise the turbo inlet made (pvc echoing type noise when letting off throttle at low rpms). While it's too quiet with no aftermarket intake, and too loud with the turbo inlet in my opinion the aftermarket intake with stock turbo inlet sounds perfect.
