Routing the line from that connects the intake manifold to the pcv to pre-turbo instead should help eliminate blow by (with a catch can).. it helped in my case, but the rings are getting weak now.

Who rebuilt the head and what was done? Were old valves with bad margins used? Good valves lapped and thrown back in? Was a leakdown test ever done?

I will have to agree, some panty ripper vids should be in order... But not in this foot of snow we just got. 398 whp should be enough to release a "quality" NE crew burnout this time

I was curious what boost was run and the final numbers but nobody was talking so I did it myself. I was the most vocal about what it would or wouldn't do on Josh's car and was curious to see if I was right. For 8 psi, I wasn't far off track.
Mike and Josh's plots on the same plot:
Same curve but far more power:
green: 8 to 9 psi
red: 14 to 15 psi
blue: 22 psi
Not sure who's plot it is but itw as said in another thread that it was a GT35R

21 psi with a gt35r should be well over 400, closer to 500whp, even with 81mm bore and 7.xx:1 compression. good job hotrex
i wouldn't really call 18° at 19 psi 'too' conservative, not over agressive, but not really conservative.

finally people are not being ignorant and seeing that at 21 psi it should be WELL over 400 (even with a stock head)
