Jesus... is this thread really 3 years old.  :scared: :scared: :scared: :scared: :scared: :scared: :scared: :scared: :scared:

Found it when looking for another intake, after reading all the pages i wondered how this faired up

ROH ECHT:
Just because this is old and to post a couple of things I'm not sure are included in the previous pages;
They did upgrade the intake for the mk6 Golf R with the DV relocation...


.....and the Volant did result in low fuel trims, on average, when they had MK6 Golf R people report their fuel trims with various intakes; on another forum. These averages was posted once ten people reported for each of these intakes. So some didn't make their list if less than ten users reported their trims;


I may have posted this all before, on those previous pages, but I'm old now (62 next month), and I just don't remember.

62, wow, good on you  :drinking:

Good info  :happy2:  Its great to see people take a scientific and detailed approach to these things rather than slapping any old intake on and calling it done.

Even 5% drift caused drivability issues on my Edition 30.  Doesn't sound a lot but it's still a large error the ECU has to work around when calculating fuel trims. I saw 8% error with my Racing Line intake over a week, which grew to 12% after a month of daily use.  Revo intake got up to 18% iirc.  LT and ST trims max out at 25% and then ECU runs out of options.

The 10-25% error intakes shouldn't even be on the market. They are utter garbage and destroy low end response.

Stock intake = 0-1% error margin.

I have the P-Flo and, with its K04, its trims typically sit at +7% (warm months)...but trims (multipl./long term - off idle) can creep up toward +10% during the colder months.
Neuspeed's older P-Flo was worse; with its MAF position much closer to the down-turn just prior to the turbo.

My warm month (US)mpg is 30 mpg (30.2: over 650 mile average) currently; 36 mpg (Imp.). I have difficulty keeping its mpg above 29 mpg (US), 34 Imp. mpg, in the cold months.
I've considered swapping to a CTS intake, but I really could be gaining very little for doing so. And this makes me think to just stay with what I have.

I know there was a good bit of hype being spread, regarding the REVO intake for some time. But in the 80+ page "Topic/Thread" where the trims were being shared, the REVO trim reports were all near the +15% mark; ±2% to 3%. I always thought if the transition in the REVO tube were further upstream, then maybe the laminar air flow would have settled better. But that's me being suspicious of the transition in their tube; just prior to the MAF and possibly disturbing the airflow at the MAF.
I know GIAC worked with EVOMS in correcting their early production period woes, regarding fuel trims, and it seemingly paid off. Sadly though, EVOMS has discontinued production of their MK5 intakes when sales for it dropped. EVOMS; another I considered.
