You are on the right track.
My opinion is the "cap" so to speak is the significant overlap of using hot NA cams.
Custom cams are most likely the ticket to big numbers and yes even on pump gas.
Right now your max output is hurt by the fact you are low compression, runing hot NA cams, and losing too much of your high boost.
It could be a reason as to why the few dyno's show a cap around 6300 rpm and raising the boost doesn't help. (seen on 3 different setups now)
You know the turbo has more in it. A 57 trim should continue to raise power to 20-22psi on the 2.5 litre and not cap around 17psi.
Someone's sure to try the oval cams at high boost sooner or later. I think they'll make monster torque but they won't hold on long enough to make monster HP.
Also the monster torque may be unusable anyway because of traction issues in the first several gears. Low rpm torque is not necessarily a good thing in a platform that can't handle it.

That brings us back to custom cams for those wanting to really push the limits.

And you wonder why I was willing to try and stick with the escape 3L cams!
I hinted as much before. I had some indecision because I was going to run lower boost for a while, but I was planning for the future.

Suneil, can you email me the dyno showing the 330 wHP on pump gas? I'm very interested.
Thanks,
