So you've made 380 on stock internals?! that's pretty awesome! We were just recently discussing how the pistons must be the weak link in our internals.
I am preparing to start my turbo build and have been debating what psi to aim for in a daily setup. I was thinking 10-12. But youve kinda built up my confidence a little more!

Almost 380 but its not safe.
The rods are too thin and the pistons wont resist too much.

i upped boost to 10psi maf volts are same as they were at 6psi 4.7 it took s a bit of fiddling with the MAF scaling but all is well now. MAF Scaling is 4.7v and 260.8g/s but my MAF size is 475g/s i am still figuring it out i may have the numbers backwards but it s fueling well hitting the target.

Do you mind sharing what Kind of timing curve are you runing in the tune?
maybe share a map of it or a log?
We have a mirage turbo, forged internals, evo 9 turbo, cams, with some custom parts, etc
but are having a hard time tuning the car to its full potential
It would be really nice to share some info, if you are ok with it.
PM Works also!
thanks

No i didnt,was all stock
Sadly the stock pistons couldnt handle that power for much time, they handle at most 310whp
I made 312whp @10psi
But i was cocky and wanted more and they went BOOM

you made 312 at 10psi? if your AFR's were safe, you must have been running A LOT of timing...
I blew my engine at 18psi with a 20g turbo...i'm fairly certain now that it only blew up because my meth/water injection pump failed... I ran 14psi for years, racing nearly every weekend with zero issues on 94 octane fuel, without water/alcohol injection...
do you have any datalogs from when it was running?
