Hi James that's pretty much the same setup that I run. I didn't really do it to get a big hit in power more so to make the power more consistent and make life a little easier for the engine. That's a good time what was your terminal speed ? Some people have said that it's possibly better to have 2 injection points for the WMI on the intake manifold of the engine as the amount of WM delivered to each bank is liable to be different. The intake for one bank has to turn back on itself and it's possible that the one bank would get more WM than the other. But if you introduce it closer to the engine I don't think it will have as much time to vapourise and mix with the incoming air.
