Following this closely.
I’m in a very similar spot on my LT4 2650 setup, currently around E50 - E55, 9.45 lower, 90mm upper, and seeing about 16 psi. DSX dual in-tank setup is holding good pressure so far, but the high side is basically at its limit already.
The Wisher aux injection looks like exactly what’s needed to safely bridge that last gap without completely reworking the fuel system. I’m planning to order the kit as soon as it’s available.
Goal is full E85 capability and supporting an 80–85mm upper pulley. 1000whp territory is the target.
Looking forward to seeing more results as these kits get out in the wild.
