More than 1.3bar with Stock EU Twins?

[Pred]

I have a problem with my twins. The specs: EU Twins, Parallel Mod, Greddy BC etc.)

 

I cant go over 1.3bar . I tested different settings but the boost dont go over 1.3bar.

 

Any Ideas?

i went at 1.5 bar to jap show on j spec

Does the boost controller have a safety limit built in to it? 1.3bar sounds like the point at which a safety would normally be set.

[Pred]

limit is @ 1.4

i try to set my boost controller to 1.1 bar but what ever i do it will still go over 1.5 bar .

seems good to me untill they go bang. i dont have a 1.2 ring , but going single soon.

could be a small leak in a pipe or the intercooler

Why would you want to go over 1.3 bar? All you'll do is generate more heat, it's unlikely you'll get more power than you would at 1.25... that's my experience anyway.

could be quality of fuel add a bottle of octane

Your singling my old red?, looking forward to it mate

I'm very interested to know how adding octane booster to the fuel can affect the mechanical operations of the boost control system.

mate i haven much knowlegde of turbo cars, from experience my car was overboosting as high as 1.71bar that was adding toulene/xylene and 2 bottles of nos octane booster to a tank,since i stopped using the additive boost has dropped down to 1.4/ 1.5bar,the only other factor i can think of is the weather has got warmer,

I saw a 5th hear test of octane boosters the other day, said they all reduce power...

[nigelboyne]

from experience in turbo and non turbo cars adding toulene/xylene increases pwr and torque along with smooth idle
