wastegate and dump valve advice

[markrenwick]

can i put a external wastegate on to my standard turbo? its a leon 1.8 20v turbo, also dump valve i know it has to be a recirc one but was considering putting a spliter d/v one on are these any good?

thanks in advance

external waste gate pointless when it involves a lot of effort.

instead of messing with the 710n (DV) I would go down the induction kit route....Get a nice sounding chatter.

I believe this can be done by bypassing the maf and having a custom map.

 

[bigben143]

its not that simple m8, why would you map the MAF out the system for?

 

[cupraslayer]

It was mentioned on here this week. Trying to think of the thread name. Was stated the maf can be bypassed and mapped to suit. Not machanically minded, so I'm only going by what people have done . I'll keep looking for the thread.

Found it..... Look in mk1 leon and go to first time lrc driver. Its in the 6th post down .

Its alright just sticking a splitter dump valve on it lol

Heard the split r valves are not ideal for 1.8ts

Going to see what its like on the softest setting where its recirculating most of the pressure had a few folk i know saying it should be alright

The 007p makes a pretty decent noise with a cone filter on.

Just bought the car yesterday and duno where to start ha ha , looked at them but i didnt like the look of the price ( im a tight arse ) and with xmas round the corner there will properly be a forge one in the near future as hoping to give it a wee bit aggression under the bonnet

 

[markrenwick]

Think im going to put a decent panel filter in it air box been drilled duno if thats a good thing or not

I'd leave the dv alone and fit an open cone.

This!

Ditch the splitter and buy a decent DV from Forge like the 006/007/008

I've just reverted back to the Bosch plastic DV from my forge 007p while trying to troubleshoot a seperate issue and the difference is unreal, the car is much smoother, way more responsive and the urgency in 3rd and 4th has returned, seems to pull much stronger now.. So my advice is stick with the Bosch dv and get an open cone, I can still hear it dumping, not quite as loud as the forge but still definitely noticeable!

Did you have the revised piston rivvs? If not the valve would have been leaking

Yes mate, revised piston and recent service courtesy of forge and there free service kit they sent me

 

[BoostHard]

With the o rings on the bottom of the piston? May have to try mine

Yeah new o-rings and greased up nicely, please do try it.. Will be interesting to know your findings

I agree with the above 100% and would never use a piston dv now. Diaphram is so much smoother and responsive IMO
