With a stock bottom end for a 4.6 Super charged with inter-cooler pushing 450 rwhp+, will the alcohol injection make it safe to go beyond 450+rwhp?

 

My guess would that your still gonna be putting stress on the engine the with the higher hp levels. I think it will just give you lower air temps

 

The main advantage of alcohol injection is that it lowers IAT temps and increases octane. This allows you to run more timing without detonating, which means more power.

Sadly, alcohol injection won't make the rods stronger so you are still taking your chances above 450whp.
