I don't know how many times I have said this, and it falls on deaf ears. That 570whp dyno pull is a cold pull. Not a realistic real-world number. 480-520whp is realistic safe numbers for a LT1 with 7-8psi on 93 when hot. Now switch to a E50 blend and it will make consistently 570-600whp in almost any conditions.

I don't know about you, but I would rather have a setup that can make sustained power in various conditions, vs a setup that is extremely reliant on perfect conditions to make power.

A lot of shops and companies are not going to admit this because they would sell a lot less parts. How many less supercharger kits would a company sell if they were truthful and said: 93 octane will work but not recommended. It's recommended to upgrade fuel system and run a E50 blend minimum or race fuel for the best and most reliable results.

100% agree King (I know you know that haha)! I’ve been an E user for a long time now… hope the Feds don’t take that statement the wrong way…

I think the point here is you CAN supercharge an LT1 at low boost and 93 octane. It’s just not even close to optimum as King mentioned, you’ll leave power on the table, and the risk of SBE damage is higher VS running at least some E in the fueling. But some people can’t/won’t run E so I guess those are the risks involved.
