Or...How about a methanol injection system?
Even if you dont care about grenading the motor, you will get a Huge performance increase if you take care of the predetonation.

Tom, I appreciate the advice, however I've already got most of it covered.
Fuel delivery is up to the task. I have a Fuelab 41402 160 gph pump, fed by a -10 sumped tank, which splits to two -8 lines before the fuel rail, and 80 lb/hr injectors. It never...never...went lean. I have lots of logs showing that the fuel system is capable of supplying the correct fuel pressure and AFR even at 16 psi and 7000 rpm.
I don't have room for an A2A intercooler, with my AC stuff in the way. I do already have a dual nozzle meth injection setup on it.
I circled one nozzle, and there is another one on the back side of the pipe that you can't see. I am also running E85.
I plan to upgrade the bottom end, since high cylinder pressure, whether from big hp, or detonation, bends rods. The stock cast pistons also don't give much room for error if you get a little too greedy or get some bad gas or something.
I've built and ran two other big turbo LS motors in the past, and never broke anything with them. Once I hurt this one early on, I didn't really care about it anymore, so I just kept turning up the wick on it to see what it would take before it came unglued...which it never truly did. Call it a science experiment
