Few Turbo Boostin Questions

[baby34]

Hi just wondering

Is it safe to boost to 11 Psi on stock turbo and no front mount intercooler. everything else stock.

And since its a manual boost controller.. how can you tell if its @ 11 psi? as the dashboard only says 7 max.

Would i be getting backfire because the boost is so high?

Thanks.

yes its safe, the dash isnt in psi i think from memory its in mmHg so the 7 is around 1 Bar

Get a real boost guage :-)

most Electronic boost controllers will show you the boost level reached too.

11psi is OK, just make sure your plugs are good, fuel system is up to scratch and your fuel is high octane.

depends on what sort of driving you are doing. if you are doing any track work, etc then 11psi without a fmic isn't the best idea, simply because the small stock intercooler suffers heatsoak pretty quickly. in winter it isn't as bad thanks to cooler temps, but still worth saving up for a fmic as your next mod.

and +1 to getting an actual boost gauge that reads in psi. the stock gauge should be reading a little bit over half way at 11psi.

if you are running your boost at 7 on the stock gauge, then any backfires are a result of the ecu trying to save the turbo by dumping in extra fuel and backing off the ignition.
