I remember this car making 850rwhp with a power sucking PD supercharger. It only had a KB BAP for fuel. I'm pretty sure the BOSS uses the exact same fuel pump.

I also remember another car with a centri supercharger running E85 going over 700rwhp with just a BAP.

Either way, over 650rwhp I would use race gas.

I would suggest a 3.6" or 3.47" pulley and race gas to get where you want to be if you insist on keeping the stock pump. I only know of one guy on this forum that ran the 3.33" pulley with a stock fuel pump and raced it (without a wastegate). The car was quick but it didn't take long and he sold his somewhat new aluminator as a hurt engine. Maybe the reason you can't find anybody running that combo is because it's not a great idea. I've done it and gave you my feedback. Your car may be different initially, but you'll eventually regret it. If you play with fire you get burned.

thanks for your good answers, I appreciate!!
