The Alky dual alky kit will raise the limits of the double pumper.
In my opinion, that thinking results in lots of engine damage?

The alky is not there to make HP, but to cool the charge and raise the point where you get detonation. You may get a little added HP with the alky, but you need more fuel, gasoline, to provide the BTU output that gives you HP. If the necessary extra fuel is NOT available, the mixture goes lean.
The HP increase with alky will come because with the cooling effect, boost and RPM can be increased. The difficult part is determining the "final" limit of this level.

Why is it that some forced induction high HP engines inject alky or even 100% water, and still develop massive HP and stay together? Most likely their fuel delivery system is capable of delivering as much fuel that is needed for their HP level.
After years of re-building many alky injected Buicks that never had any knock retard shown, but evidence of pre-ignition damage is easily recognized as the engine went lean.
What is tuning, providing enough fuel at the proper time for the HP level desired?

We overbuild our fuel systems so it is always able to supply more than is ever needed, alky injected or not.
In an alcohol fueled vehicle, it will take 3 times more alky than high octane gasoline to make the same HP, so injecting a very volatile mist into the combustion chamber without enough gasoline will be disastrous.
