So while I agree on what you have posted and it has been well thought out and supported over the last 6 months or so on fuel system. I think for me and people like me will always error on the side of robust and dependable. That is why I went to the ported heads and cam route and the IMO more efficient blower with the most headroom (stage II intercooler, D1X). So yes my setup absolutely fails the price / performance equation. but it does follow the minimum boost, max available octane to achieve target HP formula perfectly and is STILL way cheaper than a ZL1. Heck I'm I have the biggest pulley they make for the D1X (slowest turning least boost).... don't need anymore till I get wider rims a 888R tires for the rear.. don't worry I go through a set of rear tires every 5000 miles.. it will be soon...

True but its only going to take 8psi of boost with E85 to make the power I want. ADM did it with a LT4 blower, wouldn't be surprised if the Whipple can get there with less boost. Remember the Whipple makes 585whp on 91 octane with the stock pulley on a stock car. Add just e85 alone will add 60-70whp. I just want to have enough fuel system for that and I am good.
Heads/Cam would come into play if I was trying to go over 700. I would definitely shoot for the most power on motor and use less boost. That is the great thing about e85, it basically allows the same thing. I agree about putting power to the ground. No point in making more until you can use what you got.
