Fuel injector and pump choice for new turbo setup Been running my LS1 na for a while now and decided to go FI. Trying to determine if this setup will work or not.
current setup:
LS1 running stock flat top pistons with upgraded rods. 10.87:1 static comrpression with PRC stage 2.5 LS6 heads with PAC double springs. Cam is clone from the trick flow 515 kit 585/585 lift and 223/230 at 0.50 and 112 LSA. Bolting on a gt45 and planning on running 10-12 psi. I was looking at running siemens deka 80# injectors and a walbro 525 pump at 70 psi using a 1:1 fpr, and switching to e85 or even e50. Does anyone see any issues with the setup fule flow wise (outside of people not likeing the valve overlap or 112 lsa on a turbo)? Ive seen plenty of people saying they are hitting 800+ rwhp on those injectors and at 70 psi i feel like they should flow plenty but not sure the walbro 525 can keep up, though charts Ive looked at seem say it should make it. Obviously I'd like to be under 90% IDC but the car will see street crusing the most with limited track time and a few WOT pulls in mexico.
