While your post is off topic, I have experience with cranking up the pressure on the stock LT4 stuff. 3400 is about the max where the stock injectors are happy. You need a cam of course to maintain that pressure. I have a few of those setups running pretty big meth kits. I just dyno tuned a couple of ZL1's like this. One was on stock blower and stock pulley that hit 798rwhp and the other one was on a smaller cam but max effort blower and pulleys and more meth and it made just shy of 900rwhp.

Both cars with stock LT4 fuel system parts, 32% fuel lobe and meth.

The setup that I started this thread about was because I wanted the maximum amount of power without a cam or meth as it is not setup for racing. It's a street car with factory tires. Car is max effort bolt on, x port blower, and moderate pulley and can run E60-E70 depending on weather.
