safe boost levels
« on: December 31, 2004, 04:27:09 pm »
just wondering what a safe boost level is to be running on a stock 2g 7 bolt?

think it depends what turbo you are using
and what you consider safe

safe is kinda a grey area
between the engine lasting as long as possible
and the engine blowing up in the first mile

Stock. The higher you run it, the larger chance something will break. Research on supporting mods to extend the life of your engine or think about saving up for a 6 bolt solution. Lots of guys run 14-16psi on average I would say. You will get a fair life out of that.

I take no responsibility though to your driving methods as they are a direct influnce on the life of your car in any condition or modification.

James, if you're still running a 2g BOV, there really isn't much point in turning up the boost.  They can barely handle anything above stock

depends on fuel,(supply, tuning and octane rating) intercooler,(size, make and placement), and a few other things.

get a better bov, better fuel pump, run 94 octane fuel, make sure your intercooler is clean and you have no boost leaks.

Make sure your car is in top tune BEFORE you do any mods.

Even after doing all that, you should still get a datalogger, and even then, I wouldn't go much over 17 psi.

Do all that tho, and you will see a huge increase in power. Provided you do a full exhaust too.
