Psi Or Bar Boost Gauge

[pogo29]

Im a real learner on this stuff so please bare with me...

I was looking at buying a turbosmart boost tee from monster motorsport, But i want the right gauge mounted first so i dont overboost. So does it matter psi or bar? and what are the max psi/bar you can go with everything stock except uprated air filter under the bonnet? thanks.

stock ecu only fuels upto 12.5psi and then you hit fuel cut but you can't set it to 12.5 as you get creap. I've found 10-10.5psi is good then a bit of creap and its goes up to 12psi. I have psi gauge as the bar gauges dont seem to have alot of info in the dial I cant seem to use em but its personal choice. You can goto 1bar/1.1 on stock internal but you will need an aftermarket ecu i've got everthing to go 1bar but it just need setting up and i dont have time at the mo

PSI or bar is just personal preference really, it's metric or imperial.

1 bar is 14.5psi, standard you can only run up to 0.8 bar or about 12psi at the most as much above that and you'll hit the fuel cut (a safety feature of the standard ecu to prevent over boosting and hence running lean).

Thanks, psi gauge and set to 10 psi sound about right?

you dont set the gauge, the gauge tell you what the turbo/actuator is set to/doing. get a hks adjustable actuator to up the boost plus gives you a better boost hold and stops boost drop as the toyota actuator is turd!

Personally I find PSI easier/clearer to read as it's a smaller unit and on Starlets were really only using small numbers.
