FYI I saw little to no difference between stock and straight-through muffs on vf46 & 3" tbe.
Definitely sounds like +10kw but

Can I ask, how much extra dough did you spend to get from 177kw to 216kw outputs?

Turbo - $800
Headers - $600+coating
3 port boost solenoid - $150

The 2.5 has a same comp wheel and a bigger exhaust wheel, I think it is a 60mm in house blouch design, or is similar to that used in the 3076r.
Despite owning a Blouch turbo I used to doubt what they could do. Though after seeing my in the dyno still with plenty left in in, and a few other plots (from Australia/the real world) with 8cm rear housing with the 56.5mm wheel (20g-xtr and dom1.5) holding 24psi neatly to 7500rpm I am starting to think there is something to them.
Edit: wow, the GTX3071 runs a 71.4mm comp wheel and a 60mm exhaust. That is interesting.
Dopple edit: Addressing GB's spool question. I found a thread on Nasoic the other day that someone had overlaid various posters dyno graphs on one graph. The handy thing was that they were all unopened EJ25s, stock ports and cams. Obviously the numbers on the graphs were a little off as they were from different dynos, but it gave a great indication of how they performed spool wise.
One would expect similar spool performance between the dom3.5 and the gtx3076, though the 3076 on that graph will most likely come on a bit sooner as it is a twist mount.
Feel free to move this out of your build thread too Jacks.
