Hey guys,
Firstly thankyou for clicking this topic, on saturday I will be picking up my first ever turbo car, mk4 1.8T like most people that get a turbo im interested in getting a dump vavle for it at some point.
Now I have read that there are, atmos ones, recurit ones, cheap ones and expensive ones.
I have also read that done wrong, could cause problems and even worse MPG.
Now as much as I would like one, if its going to come at a cost to my engine i wont do it, I plan on really looking after this car, using only super fuel, full tank with petrol magic (the turbo one) each month, and service every 6 months.
I also have read that alot of people see dump vavles as a "chav" thing, i am in no way a chav, and to be honest im supprized a "chav" would insure a turbo as im certain they would have no year no claims :grin:
Any advice would be brilliant.
Thankyou
Nino

Best and only "dump valve" I would use is the forge 007 or 008p re-circulating valve and nothing else.

if your on a budget get one from here they are exactly the same as the forge ones and myself ,wayne i think, and a few others are using these with no probs as said its same as the forge one without the big price tag :wink: if you can get one cheaper then even better :grin:

friend of mine put one of those on his TT. 2 weeks later the seals had deteriorated. They may look the same as the forge ones but the quality just isn't there in my opinion.

Thanks alot, so it seems id be better off getting a decet forge 007 or 008 and decent turbo pipes and ensure i use a recurit valve? If my uderstanding is correct?

I was going to get one but got lucky with a genuine Forge 007

Yes you cannot run a dump valve it needs to be a recirculating type

really as on inspection they appear to be the same inside as the forge mines been on for well over a year with no probs it was nick at r-tech that recomended it to myself as he done some research on them i guess its just luck of the draw with anything you buy could be good or a bag of sh!te :smiley:
ah remember you on about one wayne didnt know if you got it or not my mistake :smiley:

They get really good reviews on Briskoda and other forums, was just about to get one but was offered a s/h Forge at a really good price.

cant fault a good deal :grin: :cool:

What power are you aiming for?

Nothing massive but thinking is like to end up at 200-250 mark in the end by the time i do everything??

There is a huge difference in 200 and 250bhp. Depending on engine code, 200bhp is achievable with nothing more than a remap. 250bhp requires a whole lot more.....silicone tip/boost pipes, turbo back exhaust, FMIC, injectors, maf, fuel pump, actuator, probably turbo then custom map.

as its hes first turbo car he wouldnt know that.
and its not the case you "can not" run a open or vent to atmosphere dump valve, its the case that the charge thats dumped will be lost to air, and as the ecu has accounted for the air its just dumped, causing it to run rich, so its not recommended.
ko3s and remap will yield 250. and the ko3s is straight swap. or for the extra effort a ko4 gives better drivablility. and pulls stonger.
-
you can run blow off valve on early agu engines as i did with no codes or problems its just not recomended and on the dyno it will put your power down as i found out :lipsrsealed:
-
you can run em on aums without codes or running issues. Does it lose power? Cant say i noticed any loss. If i did i would rather use the old plastic valve.
