Inside looks good, thanks for sharing these

Man, I love these tests. Thanks for doing this. I've been debating "upgrading" my CTS inlet to the Uni TIP and just can't justify it. Even though it'd be a ~$20 difference after reselling the CTS. The only thing that bugs me about the CTS is the way the PCV bung bottle necks a bit. I doubt that has any actual negative effect to power... now that I think of it, it might actually help prevent some turbulence.... what do you think?

How many data points do you collect for each TIP?

I looked into velocity variation exiting the elbow during the first test series. There was generally consistent performance among the aftermarket elbows with APR measuring slightly higher variation than the others I tested.

How many data points do you collect for each TIP?

I pick what looks to be an average. When running air through the part there is a good amount of turbulence and that creates constant pressure changes which then affects the flow rate. Once up to the test depression I run the test for 10-30 seconds and observe the oscillations of the airflow and estimate the center point. That's the +/- 3 CFM margin of error I refer to. The sampling rate of the digital manometer is set to 50 samples per second.

Thanks as always for your great data on this. The 034 is interesting considering the pipe diameter.

Hi Guys
I resume the thread to ask you what you think of vwr..Here in Eu is an high end performance parts for VW ... and i would like to go with a VWR inlet hose and inlet pipe ... I would not want to lose torque on low revs
PS: i have a GTI 7.5 with OEM airbox modded + drop filter and Revo stage 1

Do you think I'm doing well or do I just throw my money?
Thx..

VWR TIP and Hose should be fine. I wouldn’t consider it throwing your money away.

thx man... my worry is losing torque at lows...but from what i have read (yes..i have read all 32 pages.. LoL) i should have no problem ...

PS. think this is best G7 forum ever read bfr ...

Waste of money for stage 1.

@Diggs24
Bcs wouldn't I exploit it or do you think it's counterproductive?

Baby turbo isn't sucking enough air to need a bigger inlet.
