I don't think any amount of porting is going to make up for the hairpin corner the exhaust makes on the inlet of that turbo. I wouldn't bother with a tubular header on these though, the choke point is obviously going to be in the turbine housing. People should realize the turbine housing is designed to accelerate the flow into the turbine wheel smoothly and ts is a critical aspect to good turbine performance, not bash it into a wall and make it turn 90+ degrees. I think they would literally be better just making it more like the old "center inlet" T4 housings. They at least flowed well, although they killed turbine efficiency. I think this housing will kill efficiency and flow.
The only dyno chart they have that looks reasonably good is the GT3071R. I would put it up against an HTA Green on spool, the HTA Green would dominate it on power though.

FWIW, when I talked to them about doing some testing I did tell them that I thought it would be a waste of time to test the standard 30R-35R and the GTXR was the only stuff anyone would want to see results on. Perhaps they are just waiting to get the GTXR stuff in. They havent been in contact since the day this was initially posted.

there are 3 options.. 1st one is as i said before they dont want to sell
2nd one is they dont trust their stuff 3rd one is they dont have any knowladge about marketing They have to know that at least one of the well known vendor had to made a test unless they wouldnt sell this
People had started to talk about bad housing desing already
Also, Atp's first bolt on kits for evos were horrible We will see

It's been freshly re-built and sitting in a box in the living room now for the past few weeks.
