GR Yaris Boost dial

[Sturesmyg]

Was wondering. There is the digital boost dial simulating the turbo pressure I assume. Going from -1 -> 0 -> +1 -> +2. How far should/could it go? Meaning. How much pressure can the turbo charge? Mine usually stops at 1,5. Is the because I usually drive shorter trips and things aren’t warm yet?

As the Sherlock amongst you may have uncovered: I am not a mechanic and have approximately 15% understanding of a turbo.

A little under 1.5 bar is max.

See it like the speedometer. They usually go well beyond Vmax. In stock form the GRY will get to about 1.4. to 1.5 bar. With some minor upgrades you can exceed these to about 1.6 to 1.7. With some aftermarket turbo charger the block can reach well beyond 2.0 bar. HKS boosted the block with 2.7 to about 375 HP. (new filter, intercooler and pipework) 475 with E85.
