It sounds like your motor failed from either 2 situations either..
A - bad tuning.. premature ignition
B - your tuning was fine but simply the internals could not handel the power you were producing (due to running a large turbo even at low boost)
7psi of boost is 7psi of boost.. but weather you are makeing 150whp or 300whp.. thats what can break your motor.
Just off topic.. i know D16s standard rods are only good for 200whp. Eg car a could run a T25 on 7psi and make 150whp tuned mildly... and another identical car could run a
Gt35R on 7psi and make 250whp tuned mildly.. and Boom! throw a rod out the block (similar to lukezen)

Yeah the tune was fine and the engine only had like 40-50 thou on it...twas fairly virgin. Could be a range of things that could of caused the issue. I just think it was a combination of a t04e with solid boost and high rpm and possibly slight premature ignition and thats all it needs really and things can all go south very fast.
But i dont regret doing 9:1 compression now at all. Once i have it fully boosted to 20psi and i hear it wind up im seriously going to jizz in my pants "like at the end of sixth sence was bruice willis was dead, i Jizzed in my pants"
i see fastfwd point and understand from his experience where he is coming from..........
but like i have said before.................there is nothing better than driving ur stock internal high comp honda all day every day.....and once u open the throttle and reach 4000-4500rpm............ur on boost and the gate is screaming away...........
my setup has been going strong for almost a year now, and it gets driven daily............
no compromise on drivability for daily duties with high comp off boost, and the thrill, exciting pull when on boost (7.5psi) and the stock high comp b18cr.......
like many people have said, an engine can fail at any given time for a number of reasons.............it could be tune, it could be oil pressure, it could be 'its time is up'
in ur case fastfwd, i think it was badluck, as if it was tune, im pretty sure it would have shit itself a lot earlier than 6 months down the track...............
Yeah tru tru but we all learn from our experiences and im just sharing/venting mine. Just chatting with this guy on another thread and he was running 16psi on stock internals/compression and i couldnt believe him and still dont really but he seams to have this other guy backing him.
IEVAQ8 you just commented on it also, i wasnt saying its not possible to make that power on a stock motor i was saying that its not possible to be pushing 16psi on a stock motor with stock compression.

fairly insain if its tru.
I too have heard of people running 15psi on stock internals hence why I think 10psi would be completely safe

Of course it is true. You can run 20psi and more on a stock motor if you want. You'll have awsome power for a whole 5 seconds flat out. Or you can run 15 psi for 20 seconds flat out. Or 8 psi flat our for a minute. (made up figures)
Its not the Psi that kills a motor its 'how you drive it' and how its tuned. If your running high boost on the street, giving it a spurt here and there so often, you'll never have any problems. If your going to be flat out on the track its gonna blow eventually. That goes for any motor, if your thermal management is not up to scratch it will eventually blow. As always its a lot of things to consider, not Psi.
