I'm hoping replacement of the filters , as with a few miles on them , they cant just be turned around ......
Nice work on getting to the bottom of this RR  :happy2:
guess the filter manufacturer should really add some markings to the filters to avoid the issue

....It's not official yet but Forge are thinking of charging for a new pair of filters (with carbonfibre casings, I assume) and then giving a complete refund when they receive your old filters. I'll keep y'all posted - I'm waiting for an email from them.

The markings are already there in the form of the arrows. The problem was interpretation - Even Forge USA and Forge UK were not in agreement before now.



^ This arrow is meant to indicate air going IN towards the MAF. I don't/didn't see it that way myself and neither did Forge UK originally  :rolleye:

Hmm, ok so how are we supposed to interpret the arrows on the other side of the cannister?   :confused:

Carnt believe this is still going on, how hard can it be to put a filter on the right way round. It does look rather comical and amatuerish of Forge to say they know this stuff inside and out......well supposed to :rolleye:.

I agree - Forge have made a right cock-up of this and furthermore have taken far too long to sort the matter out with some definitive answers. However, it's still (in my opinion) an excellent product.

Is anyone running a TwinTake on a standard car with no mods at all?
This part of the review concerns me a little as i want to install the twintake but don’t want to encounter any fuel cuts or confuse the ECU

THE KNOCK-ON EFFECT:

As you increase the efficiency of your air intake you may reach a point where the AFR (Air to Fuel Ratio) causes running problems which the ECU then protects the engine from by applying fuel cuts. But whilst driving on the road midst an overtake, this doesn't protect you!. The expensive solution is to have an aftermarket fuel pump and appropriate remap for it. The easier way is to reduce your Boost setting but this is probably only possible on Revo software which enables fine tuning Boost/Timing/Fuelling by either the user or agent - An extremely useful feature on any modified car. As it turned out, with JKM's expertise we were able to keep the Boost at 7 but reduced the Fuelling from 9 to 8.


Or does the above relate more to a mapped car?

....As I understand it, the ECU however it's mapped (standard or aftermarket) will automatically make adjustments to best cater for the demands it is subjected to. I now (today) know that Forge fitted a Twintake to a completely standard Leon Cupra without any subsequent problems. Perhaps I should modify my review accordingly.

My individual car will have needed fuelling adjustment due to being Revo Stage 2 and having other engine performance modifications.

HTH  :happy2:

Brilliant i was hoping you would reply Robin, ah that makes a bit more sense then that the ECU is adaptive and will "learn" again with the extra amount of air being forced in.

Thanks robin!  :happy2:

....I think that it's the Revo Stage2 instructions via the ECU which will be making the demands which then necessitate the fuelling being catered for.

Revo Stage2+ definitely needs an aftermarket fuel pump according to most reports. I'm happy to stay at Revo2.

surely any arrow would be pointing in the direction of the air flow.

Minds fine now...and i have marked which way it should be on my car however mine was not installed correctly well according to the forge manual but this awhile ago now and it was a test product too. but yea over all its working fine.
