Default How much boost and timing

How much boost and timing can I run on a ej207 v8 with stock bottom end, gtx 3076r + meth, 625 head studs, and built heads with cams?

Right now I'm running 27 psi and 24 degrees at redline but I want more power. How much can I turn it up?

We can't tell you this as it varies from engine to engine.

Your tuner is the only one who should be altering timing and boost if you aren't comfortable tuning yourself.

Depends on a lot if things you didn't list, but from naisoc water meth sticky:

"I want m@d p0w3r y0! Great! Some have been able to go as agressive as: 3 more PSI, 5 more degrees timing, and 12.5-1 a/f without detonation and safe EGTS!!!!!!!!"

Although i would be more concerned with the torque capabilities and clearances of your rods and pistons at this point cause your already at the big boy boost numbers.

tyr in small incriments. 24 is a pretty good amount if you want more I would go with a bigger turbo, ie 3576 or the new g30 770, what are you making btw?
