Thank you for the transparency, Ash really appreciate the honesty and testing the kit for us RS owners, saves us ££!. Most would not share the the the things that did not work well. Thank you!
Just being honest mate... I'm not bashing the product either but i feel it needs a revision maybe? 🤷 I'll keep you guys in the loop regarding how i get on with forge
i have the GFB DV and i mate really good figures on the dyno at RS tuning. Id say go for that mate its defo an upgrade but make sure you buy the correct revision of the GFB, cant remember if the GFB comes oiled or not... I know after a while they do need oiled a little as maintance.
Had the GFB on my m135i, solid part that they made. Not a big fan of the spacer, I would like to have something that’s more than just sound. Happy that the boost leak was not something bigger.
Ash, thanks for feedback, I have two of these spacers installed on both Megane 4 RS Trophy and I didn't notice anything yet. Maybe we should contact Forge Motorsport to have some advice about this issue ? Maybe some gasket sealant on the surfaces in contact will do the job ? I don't know.
Have you remapped yours? I'm thinking of getting one as the first little mod I do to my 280 just to get some more noise without spending over £200, maybe as Ash said, it's not built to handle the added boost from the remap.
What about placing a thin and flat rubber gasket where the piston of the valve is in contact with the metal where normally we should have a recess ? It should work to ensure there is no leak at all between those 2 parts.
Do you reckon it might be worth having the map checked? As it was mapped with the spacer on I'm guessing that the blow-by was happening when it was mapped too. If you're getting slightly more boost pressure it could be running a tad leaner. Not that it would be massive I wouldn't have thought.
I don't think it'll be a major issue. Could be wrong. Like you said it's peace of mind. If you do end up with a gfb diverter valve let us all know where you get it. The only one I can find is the forge recirc valve which I'm ordering. Good to have you back as well. Think you're the only one doing any proper content on the mk4's 👊🏻👍🏻
And the moral of the story is, leave things alone, most aftermarket parts people fit are the parts that are at fault and most end up putting standard parts back anyway.
i have the GFB DV and iv had mine mapped and made the most torque of any MK4 RS iv seen mapped by paul at RS tuning. Could this be a factor? its possbile. Either way, im going to say its an upgrade. If we all had that mentally (which i assume is if it aint broke dont fix it, or in this case upgrade) no one would get aftermarket anything.
@@VersionOneUK So you think it's always been like that? You do wonder why Forge never added a seal down there. Have the mentioned anything about it being a defect?
@@SuperSnoopy78 i think thats the case mate yes... Like i say I don't know for sure how much boost is getting by but if smokes with fairly lowish pressure is getting through i'd imagine quite a bit. I have informed forge of the issue so may need a revision, but I'll keep you all updated
I got it to do a video mate, i don't want to start chopping stuff up for a bov so I'll probably just get a GFB diverter valve soon. Was basically a test to see if it was any good for noise for people that like easy mods

Yeah i had one on my clio trophy mate, proper sturdy bit of gear!!
@@VersionOneUK if you want the part number or anything let me know and ill have a look on the box, im sure my unit fits both the clio and the megane.
@@johnboy2436 yeah i do believe they are the same mate, i was pissed because i sold my clio and forgot to take it off 😂😂
@@johnboy2436 have you got the part number for the GFB for the meg? By the looks of things its the same as the clio just want to be sure. Nice one!
Would be great if you could get in contact with Forge about this and letting us know the reaction in a further video. 👍
Already on it mate! I will keep you updated

Yeah i ran the gfb on my clio trophy before this, quietened down my intake quite alot. Great mod though!

I've already been in contact with them mate waiting to hear back!
@@VersionOneUK Great ! Thanks for this. Hope they will produce a version 2 for you... Version One ! ;-)
@@MrToonfish we'll see mate!

The leak isn't either of the o rings mate, its from the centre

I will get it checked mate, i was going to just for piece of mind

@@teljacobs1982 Thanks mate, and will do! I got mine off gfb's ebay store originally, but i will be looking into one for sure

Oow interesting. Would love to know if there is design floor in them. Wondering if to remove mine now :S But I do like the noise it makes...
I don't think the noise is worth the performance mate personally... The open filter still mates a good noise 👌🔥

Those Forge spacers are trash bought one for my 208 GTi but never fitted it because it still used the standard diaphragm

@VersionOneUK GFB is the way to go in these cases got one on my 208 they're the business and hold boost really well 👌
Save yourself the hassle and throw it in the bin, no need for it anyway.
Only had it on for a video mate
@@VersionOneUK hope you never paid for it then
