I have a 27/6 that I almost had off the car today, but ran out of time. I have had it on the car for about 7-10k miles. I had planned to tune my Viesse softare, but never got a chance. So I have not had it past 12 psi or controlled by boost controller, only tial wastegate. But it still spooled to 12psi around 3k. I had a AFM relocation kit, which I think helped quicken the spool.
I plan to got back to the shop where the car is in a couple weeks, and can have off. Sooner if needed.
It was made by Charlie @ Evergreen turbo. I had 2 made, this first one outflowed my AFM, so I had a second made, which is this one, that would not. I had planned to run 15-16psi. This one should flow nice to 18psi if you desired to boost that high.
PM me if interested, or I can give you more info.
BTW this AFM kit is for sale as well.
