AMS EVO X makes 550whp :)
They might of done it intentionally to keep the power down on the stock block. Or just not enough fuel so they taper it. I doubt on q16 mix they would have a problem holding boost on a 35r but I could be wrong. I stick by my guess of its intentional with some reason/s.

Boost controller has a soft spring in it I think. I kind of just did this on a 'whim' without any planning to see what it would do. Easy 550whp with a completely stock block gets a big 'thumbs up' from me! I literally spent about 15-20 minutes doing this... although I am pretty quick at what I do 
Great work guys this is good info cause i was wondering what are the limts on the stock sleeves keep going on power like to see what the sleeves can hold up to before they go i am estimatng around 650 to 700 i think it is not nessisary till then
thats some serious torque up top with stock cams, wow. I want to see this same car with cams added to it.
got any dyno sheets of a IX with a 35R and around the same whp on your dyno? interested to see torque up top

The piston ring end gaps are not set up for this boost level. Setting expectations that this is "easy" is not a responsible position IMO. I am sure Martin can comment on this subject from an engine building standpoint.
Someone was asking for the weak link? There it is. Ring end gaps from the factory are too small. Excessive boost closes the ring end gaps until they touch and break, taking the ring land and part of the piston with it out the turbine housing. This result will also require rebuilding the turbo with a replacement turbine shaft or having it upgraded to a larger variant using the broken turbo as a core.
You've been warned.

You recommend taking out the rings and increasing the gap?
Great setup AMS! I sure hope the motor stands up to the punishment that would be awesome!
It is something we have considered, however once you do all that, you might as well build the engine correctly with forged parts.
