K22SUP Posted June 11, 2015 Share Posted June 11, 2015 Hi guys can you'd have a look through pics and see if you see anything untoward pipes that are not there or is this normal with dump valve ect removed Quote Link to comment Share on other sites More sharing options...
ScottC Posted June 11, 2015 Share Posted June 11, 2015 There are pipes missing if thats what you mean Quote Link to comment Share on other sites More sharing options...
K22SUP Posted June 11, 2015 Author Share Posted June 11, 2015 Yes I just wondered should there be as many and should they be capped Quote Link to comment Share on other sites More sharing options...
MRX Posted June 11, 2015 Share Posted June 11, 2015 Is it running in TTC mode? Quote Link to comment Share on other sites More sharing options...
K22SUP Posted June 11, 2015 Author Share Posted June 11, 2015 (edited) No it's sequential in one of the pics u will also see a metal pipe under inlet manifold I have been having hesitation issues at high revs coil clips now changed new plugs so am just inspecting everything else Edited June 11, 2015 by K22SUP (see edit history) Quote Link to comment Share on other sites More sharing options...
K22SUP Posted June 11, 2015 Author Share Posted June 11, 2015 just more pics to let you'd have a look Quote Link to comment Share on other sites More sharing options...

K22SUP Posted June 11, 2015 Author Share Posted June 11, 2015 The car is running bpu inc boost controller but second turbo def come on at around 4000 rpm ? So as far as I am aware it's sequential but I can see a hose on mine looped and the two on yours are not makes me wonder Quote Link to comment Share on other sites More sharing options...

masterfett Posted June 11, 2015 Share Posted June 11, 2015 The car is running bpu inc boost controller but second turbo def come on at around 4000 rpm ? So as far as I am aware it's sequential but I can see a hose on mine looped and the two on yours are not makes me wonder pretty easy to tell. if first turbo comes on first at about 1800rpm then you get second turbo at 4000, you are seq. if no boost till 3500/4000rpm sequential. but doesn't look 100% right to me.. pretty sure my pipework doesn't look like that.

K22SUP Posted June 11, 2015 Author Share Posted June 11, 2015 Aye certainly feel second turbo around 4000 rpm but maybe it's both I really need to know how it should be piped with the modifications or is it correct which by sound of it I don't think so Quote Link to comment Share on other sites More sharing options...
masterfett Posted June 11, 2015 Share Posted June 11, 2015 i assume if you have a boost controller you also have a boost gauge? so you will see if you are in positive boost before 4000 rpm... if not well you probably should get one in order to monitor what the boost is doing.. however you will hear the first turbo come on at 1800 revs, mine whistle like hell.. if you cant hear your turbo before 4000rpm i would say its either in TTC mode or something is wrong. i will have a look at my pipework tomorrow and see if i can help you out a bit further.

Mcdade Posted June 11, 2015 Share Posted June 11, 2015 Mine are the same as benjy's mate. Quote Link to comment Share on other sites More sharing options...
K22SUP Posted June 11, 2015 Author Share Posted June 11, 2015 Hmm am sure it starts to show positive boost we'll before 4000 rpm but a think either it's been piped because something is pumped or because he thought it would be better if anyone has any pics of there vac pipes with boost controller ect please post them up I will get it changed over why they are all looped like that I dint know unless someone on here does Quote Link to comment Share on other sites More sharing options...
Scoot Posted June 11, 2015 Share Posted June 11, 2015 Ed where about in Scotland are you? I might be able to take a look at it tomorrow. Quote Link to comment Share on other sites More sharing options...
Ian C Posted June 12, 2015 Share Posted June 12, 2015 (edited) Have a look here: http://www.mkivsupra.net/vbb/showthread.php?35924-Sequential-turbo-hoses And here: http://www.mkivsupra.net/vbb/showthread.php?35926-The-sequential-system That should tell you how things are meant to be plumbed in and what might be going wrong and why if they aren't like that. Having said that: The two uncapped pipes at the back of the engine are technically okay if you've got a boost controller plumbed in properly, they are a return-to-intake channel for the EBV VSV (which is now directly plumbed into the intake) and the wastegate VSV (which I assume is no longer used due to boost controller). The uncapped metal pipe at the front of the engine is the other end of the wastegate VSV connection so again, not really a problem. The uncapped metal pipe under the intake manifold is the stock fuel return from the stock FPR, which you don't have, so that is also technically okay. I say technically as I can't really see a reason why you'd need the aftermarket FPR that you have as it can only cause problems rather than improvements For example, if it's set to the wrong static pressure or it's a ghastly rising rate jobber - both of those might give you a high boost misfire by cocking up the fuelling. The only query I have is where the tee'd off hose from the BOV goes. Probably to a boost gauge or something?

K22SUP Posted June 12, 2015 Author Share Posted June 12, 2015 Hi Ian thanks I have had a look basically as far as I can see hopefully beginning to understand we block off egcv and the waste hate actually sends vacuum to egvb hence pipes been like that I have changed manifold pipe egvb return pressure from waste gate so I am getting a better understanding are these valves electronically switched by ecu ? Or does egvb work from vacuum from waste gate actuator ? So we don't use it anyway with boost controller ? Also as far as I read it should be one on end of actuator capped and boost controller plumbed into top and turbo mines is not or do both ports on actuator do the same Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 12, 2015 Share Posted June 12, 2015 Ive got an opinion, ditch the chav valve Quote Link to comment Share on other sites More sharing options...
