10psi of resistance doesn't equal any hp, it's just the amount of resistance or force that the turbo is applying.
I'm just trying to get him to realize that reistance (otherwise known as boost pressure) has nothing to do with the limiting factor of what the engine can handle. His engine can handle about 300whp, regardless if thats 6psi or 18psi, if he's under 300whp it doesn't matter how much boost he runs.
The two main things that will break a motor.
1) exceeding the limitations of the motor (power wise so in this case 300whp)
2) crappy tuning. You can blow your motor on 5psi if you have crappy tuning.
Here is a little example.
My bone stock b16a made 199whp @10psi running a small garrett t3 turbo. (.42 /.48 )
I replaced that turbo with a larger t3t4 (.57 trim .63A/R) At 9.5psi (.65 bar) my stock engine made 226whp same exact tuning set-up. I switched to hondata and it put down 248Whp @ 9.5psi.
So without changing the tuning I picked up at least 27whp just by going with larger turbo, who knows it probabaly could be more since I dyno'd the first time in the winter(35 degree's out) and the second time in the summer when it was about 70 degree's.
Invest in the tuning and keep it below 300whp and you'll be fine.
Still here... sorta...
