We'll be posting up those volume pics in the next day or 2. The size, diameter, radious, angle sure come into focus with the pictures I posted. I think we should market our turbine side as being so much bigger/volume than anything on the market.
So many people; get caught up in the hype about the divorced wastegate, when in-fact on a stock 9 turbo our turbine pipe is the key to our power increases. Now on a larger turbo ie; FP green then the wastegate would have more of an effect however we still feel that our huge turbine exhaust tube is our power producer.
We also have been R&Ding the auto-x extension pipe as well as some other super secret future EvoPowerMods products, so stay tuned.....
Thanks for all the weekend orders, and all the PM's/Emails. We will work hard this week fabricating your orders for shipout asap.
If you are interested in our O2 Housing/Divorced Wastegate; let me know and I'll answer all of your questions. We can make you one to order in a very short time frame, order one today and get it shipped out in 7-10 days.

Kevin, here is the comparison I promised. 3rd gear pulls before and after the dump. Boost controlled via Greddy Profec B Spec II. No settings changed on the boost controller. Evo IX MR. 255/40/17s.
Baseline: full boost @ 3250
O2 Dump: full boost @ 3188
Spool benefits were slightly greater in 4th gear, but I do not have a log of that. I will plan to log spool in 3rd and 4th to verify when I install the part on my own vehicle.

As I've stated many times, when I install the part on my own vehicle I plan to test boost response via my JDM MAP sensor.
EDIT :: BTW, before even posting that comparison I stated that load was not boost ...
Bryan, I honestly feel like you are trying to discredit me and I'm not sure why ...

Not at all. Just trying to keep the small amount of actual data posted in this thread honest.

I've edited the original post to avoid confusion.
EDIT :: For reference, here you can see a comparison of logged boost vs 2-byte load (used in my comparison earlier) ...

My wording was incorrect, but I do feel that the spool comparison was valid due to the similarities that boost and load share.
