Need advice for upgrades
hey guys, just purchased a 99 FRC with built LS6 with a D1SC. It currently has 60# injectors, not sure about the fuel pump with a KB BAP, and a 5" pulley running 5-6psi. I ordered a Snow Perfomance meth inj kit and a 4.38 pulley to run more boost. I'm thinking I'll have to jump to 80lbers and was wondering what other support mods/fuel mods I might expect to need?
Thanks!
Thanks!

nice setup so lets say you want for example 700 at the tire
calc what inj size you need
I'm at 800 at the tire but I went with bosch 127 as I'll be running e85
that's something to think about as e85 works great with boost but you'll need a lot of it! I figure + 40% bump in flow above the amount needed for that hp level on gas to be safe and same with injectors
fuel system upgrades on the c5 can get expensive
I'd get rid of the bap and run proper pumps with the capacity you are going to need
so a bit of advice don't skimp on the fuel system and give yourself room to grow!!

Sorry! It does have a cam, headers, exhaust, ported LS6 intake... just more concerned with the fuel system. What's the typical setup most are running? I'm new to the corvette world and I've been looking trying to find info but there's a lot of endless/pointless threads haha!
E85 is kind of difficult around here, there's none at the pumps and it's a drive to get in bulk. So I'm kind of stuck w 93/meth.
with that in mind, what should I be looking at getting into with the fuel setup if I get rid of the BAP??

I want to be around 700whp roughly, was looking at an ECS setup (kind of pricey), a Racetronix dual intank setup, or an external secondary pump.
Maybe can get away with a Lingenfelter Bosch 350?
Just looking for more suggestions. It is more of a weekend/street car so I do drive it often.

with dual meth and 80lb injectors, ECS stage 2 fuel system and stock c6 z06 in tank pump doing 900whp on 91 octane pump gas with a D1SC with rock steady AFR and fuel pressure all the way to 175+mph at 1/2 mile
