Boost Pressure?

[SPYD3R]

Hey I wanted to know what would be a safe pressure to run at for daily driving without blowing something up. You can look at what i have on my car in my profile. Also, what is safe to run for doing some sort of street race if the need ever arises?

Thanks

I would say that safe would be 17ish for daily driving.
But the only way to tell what to tune it for the high setting is to do some logs and turn the boost up until right before it knocks.

Don't street race.

I meant street race as in just like a set-up not to actually do it. Just for the feel and power.

sureeeeee.....

so 17 psi would be safe for daily driving without busting anything. Can anyone else give their input and vouch that that is correct?

Get a datalogger so you can measure your knock count under different psi's of boost. If you're knock count is at 7 or more, your ecu is going to retard your timing, anything under 3 and your timing will continue to advance. I would shoot for 0 counts idealy, and keep the boost at that level.

Guesss that means I am going to have to buy a datalogger...

I thought its pretty impossible to count knock on 2g. And you cant tune at all, if you stop increasing the boost as soon as timing advance decreases. For example I get about 30 deg advance at some point and if I accelerate, it should fall to about 10, 13, 15 deg advance or so? Am I correct? If the timingi falls under 10 deg advance, then something is not fine.... thats the way I have understood. If im wrong, please let me know.

With an safc

 

[SPYD3R]

Its impossible to count knock with an SAFC on, or you count it with the SAFC?

 

[president95]

The safc is no good for counting knock
