Can someone explain in detail how to do the 1 bar loop?
Last time I tried it my car just boosted like crazy. I think it may of been down to the t peice I used but I just want to make sure I'm doing it right?

Theres a diagram in the useful diagrams wich shows you how to do it but you will need the restrictor pipe otherwise you wont get 1bar bill....

I like how it's called "the dodgey 14 psi trick" Laughing

I might just stick with the unstable bleed valve. I'm scared to try the 1 bar loop mod again because my turbo about shit itself last time! Lol

The thing is when I did it last time it hit about 1.4 bar before I backed off. I may of crushed the t peice putting the pipes on because it twisted when I pulled the pipes off. I'm just afraid to do it again incase it wasn't the t peice at fault

basically as above it just bleeds off into the induction pipe.

I cant really understand why they call it a 1 bar loop because if you disconnect the multiplug from stock boost control solenoid you don't even have to loop it and it will still hit bang on 1 bar with restrictor pipe just by bleeding it back into intake

I would think it was more an likely be the tpiece as its the same efect as the restrictor ...

I can't explain why but I'm getting well over 1 bar with "the 1 bar mod"  confused 

I'm seeing 1.2 - 1.3 bar and I dare not keep my foot in any longer to see what it's boosting to.

God knows why it's doing that?

No mate I'm sure I haven't, I just put the t-peice were the MBC was and T'd it to the intake pipe as per the diagram. I don't understand why it's doing that and I don't want to find out if theres a limit to the boost when it's set up that way because as soon as I see it go over a bar I poo my pants lol
