Coming from the N/A class. Got tired of being N/A and since everyone is going boosted, I am as well. So question is, how safe am I going on the procharger? I'm FBO/e85, I know I'll have to go back to pump gas. My main question is, will I be safe with my stock fuel system for awhile before I get the funds to upgrade the fuel system? Is there anything to watch out for?

Procharger on the stock fuel system won't be much faster then your full bolt-on E85 setup. The reason is the swing in power going from E85 back to pump gas and how much timing you will have to pull to run pump gas and boost. You will be going from 27-28 degrees of timing down to 12-15. That right there is probably pushing 60hp loss from your NA power. Then you feed it 7psi of boost and you might gain 140-150hp back. So now you are up 80-90hp but you also added 60-80lbs to the nose of the car. And what you have is a low 11 second car which is probably close to where you are at now except the boost setup is probably going to trap a little harder. My recommendation if you are not wanting to spend money on the fuel system is to At least put a meth kit on it(for added octane and cooling) so you can feed it some timing. If you can get it up to 18-20 degrees it will feel like a entirely different car compared to 12-15. Octane is very important on these high compression engines as you have likely seen from how well they respond to E85 even when NA. That tells you right there that Pump gas and boost on a stock compression LT1 really limits their capability.
