Anyone see Matt's prototype dual injector setup?

I heard about it. But haven't seen it yet. I talked about doing this for a big turbo a year and a half ago before we were able to raise the fuel pressure. Don't have facebook to see the pics.
i may not post much, but do you ever have anything positive to say? I get it you think your parts are the best, but it doesnt mean you have to be a douche to zzp or others...honestly I wouldve bought a few things from you guys but your attitude towards zzp in other threads made me not....

I never once brought up werks, on this subject. So, I would appreciate if you wouldn't be so quick to take this post simply as negativity. Its simply me looking for information on the setup, not bashing.

What did I say that was wrong there, sir? All I said is that BTF has done it for years, meaning, its been done, and its been proven. then I raised an issue that has been raised in numerous different platforms that I follow (many of the issues being raised on hondas), when running secondary injectors. The issue being fuel aggregation on the opposite side of the intake manifold. This is a real problem, and I would like to see if ZZP has a solution to that. Fuel aggregation is a real problem when adding secondary injectors to ANY intake manifold, whether it be ours, or a Skunk2 on a honda.

Thats what I am trying to do. Its not new, at all. Its just relatively unseen. 90% of the people over here don't even know who BTF is, I am willing to bet. I was just saying this is a proven setup. It works. But I just wanna know how well it works, due to fuel aggregation. Thats it!
As of right now, I am running my car with the stock turbo and E85. I was able to put down 355whp sae on the DI injectors only(2800psi). I then installed the port fuel injectors and put down exactly the same power with the DI injectors providing ~2/3 of the fuel and the port injectors providing ~1/3. This was good news since I was afraid that we might lose a little power due to the port injection not being able to utilize the benefits of direct injection. My theory is that above 25% duty cycle, DI gains are quickly diminishing. In other words, the shortened pulses of the DI system are helping at least as much as the port injection is hurting.

Yes, they are angled nearly 45 degrees.
