Only Injectors and smaller pulley I added.

So you were losing to the bolt on V8s before the smaller pulley and bigger injectors. Have you gotten them to run again now that you have increased power?

Not yet but I'll upload some videos next week after we run. It wont be close

The looming question is still AFR at redline. Does your dyno chart show it and can you post a better pic?

Regarding running e85 and supercharger: One camp says the limiting factor is the stock fuel pump, the other camp says the stock fuel pump is sufficient, it's the injectors limiting us. Seeing what your AFR is at redline will definitely shed some light here (and have a lot of supercharged people buying new injectors and getting a e85 tune)

You also need to consider load. Maybe you are fine in 1st, 2nd, 3rd and 4th. But when you decide to do that too speed run in 5th, there is more load and you are pulling for longer and the AFR goes lean.

If you do the math and are comfortable with injector capacity given your BSFC assumptions, then I would still look into the pump. Years ago, Drew found issues with a VT700 kit and added a Hobbs switch activated 2nd pump. He seemed to be pretty thorough and I think ESS helped, so I would double check the assumption that the pump is not an issue at high flow levels.

Would love to see some 3rd or 4th gear pulls, thanks

Fuel-it sells a nice kit in the event the fuel pump is maxed out, might be a good idea regardless just to help with longevity of the stock pump at these levels.
