DannoSupra Posted November 12, 2007 Share Posted November 12, 2007 Has anyone experienced Turbo Surge on 1st tubby before? This is what happens. From 2000rpm, 100% Throttle in 3rd, to say 4000rpm, maybe 4500rpm. It bounces between 1Bar and 1.1Bar. Then as soon as the 2nd turbo is about to kick in, it drops to 0.7 then she kicks in up to 1.2Bar Here's a vid i did on the way home from work. Hope it'll work: http://s77.photobucket.com/albums/j75/DannoSupra/?action=view¤t=12112007024.flv Link to comment Share on other sites More sharing options...
Guigsy Posted November 12, 2007 Share Posted November 12, 2007 seems backwards to me. My first turbo boosts to 0.5 bar and is hardly noticable then the 2nd one comes on it goes up to anywhere between 1 and 1.2bar. No drop between Link to comment Share on other sites More sharing options...
colsoop Posted November 12, 2007 Share Posted November 12, 2007 Do you have access to another gauge to confirm thats whats happening. That looks like a gauge issue to me. Link to comment Share on other sites More sharing options...
DannoSupra Posted November 12, 2007 Author Share Posted November 12, 2007 Nothing wrong with the gauge, you can feel and hear the difference as the boost fluctuates Link to comment Share on other sites More sharing options...
djskeme Posted November 12, 2007 Share Posted November 12, 2007 Mine was doing this...and it got much worse the more i drove it when the clutch and fly wheel were on the way out...it was the clutch slipping under all the power of the second turbo boost..then biting and kicking in properly.

Alex Posted November 13, 2007 Share Posted November 13, 2007 It won't be surge....that's something else. It does sound like you have an issue with the levels of boost created by the No.1 turbo - its quite high. Check the hoses on above the turbo's towards the back and opposite the brake cylinder.

DannoSupra Posted November 13, 2007 Author Share Posted November 13, 2007 I have got an AVC'r on it. Has anyone got the diagram for doing all the plumbing for the vac pipes? I've lost mine :@ Link to comment Share on other sites More sharing options...
Mike M Posted November 13, 2007 Share Posted November 13, 2007 Kind of sounds like the waste gate vsv isn't doing its job as that controls No-1's boost. Link to comment Share on other sites More sharing options...

DannoSupra Posted December 6, 2007 Author Share Posted December 6, 2007 I've just put the stock vac pipes back on the car now, and it worked a treat! Link to comment Share on other sites More sharing options...
