GTI Forge TWINtake air intake - Review....

[RedRobin]

I have noticed that in my instructions for my twintake the install picture shows the pipework wrapped in what look likes exhaust wrap.

Do my pipes need wrapping? If so any recommendations on suitable material.

....No, they don't need wrapping. IIRC, the Forge representative in the USA has wrapped his and I expect that Forge have used his photos without taking enough care to check them out for being possibly misleading. I'm sorry to say that Forge are poor when it comes to installation instructions etc - As I experienced with the filter cannisters being instructed to fit the wrong way around! < See earlier in this thread.

Is the install pic you have online? - I'd like to see it with a view to suggesting to Forge that they correct it.

Their product is excellent though.

without reading 21 pages... was there an answer to which way round the filters should be? Should it be as the cutaway diagram you showed?

Yes, as the cutaway illustration. That assumes that the previous owner had them fitted this way around. You don't want to reverse their orientation because of the debris collected then being on the engine side.

Tbh,it isn't that load..had mine fitted today & I can hear a whoosh sound at high revs..

I also get a whistling noise when accelerating hard, I just wondered if I have a leak somewhere or is this normal. Car is pulling fine and mpg has gone up so not convinced there is a leak anywhere (replaced DV a few weeks ago with the 'G' version.

I had mine fitted a few weeks ago, it tends to whistle when i'm at biting point, midway between changing gears, i did at first think, oh sh*t, there must be a leak somewhere, but i think this is just the particular sound it makes!!

[ianv5]

That's good news mine makes the same noise where you describe it.

I did have fun connecting the hose nearest the turbo but managed to sort it in the end.

The whoosh or the whistle sound mate?

[gigolo456]

I get the whoosh noise when changing gears as i give it some right foot, whereas i get the whistle when going at low speeds, like at biting point before i give it some right foot, if that makes sense!>

I don't hear any 'whistling' (DSG and K03 and also a Forge DV). I hear plenty of other sounds but no 'whistling'.

[gigolo456]

oh right, so you don't hear a whistling noise at all, in any gear, or the build up to any gear, could this be a 'manual only' trait???

....That's right, no whistling at all. I would enjoy a gentle whistle if I had one.

The nearest sound I hear is some delicious gear whines in certain circumstances. This is due to sound transfer by having a full set of VWR engine mounts.

I may speak to Forge this afternoon about the whistling and report back here.

[gigolo456]

Cheers RR, plse do, you're right though, it does make some lovely sounds, well i think so anyway, but if there is a chance that it's not operating to its best ability, due to some whistle (leak perhaps), would certainly be a concern...

Okay, will do - Job #432 on my list! After I've watched 'Neighbours'.

I may be wrong but I think that if there was a leak somewhere in the Twintake system, you would feel it via a difference in performance. A boost gauge is very useful in these circumstances.
