Injectors and pump for SC

Postby nixwrx » Tue Apr 12, 2016 1:18 pm

Guys just wondering - for the 3.0 - what the fuel flow recommendations are for a SC set-up, in terms of fuel pump rating and injectors. And whether an uprated fuel pressure regulator also is recommended? (or anything else in the fuel delivery system for that matter)

And whether the above recommendations change based on 98 vs E85? With some headroom there for safety in either case.

FYI not yet SC'd but hope to do so later this year. Currently running a Kobe 265 pump and E85.

Cheers!

Running a DW65c pump the pink injectors were supplied with the kit. DW65c is 265lph pump, don't have E85 available in the UK but if you need more a DW300c will give 340lph and is a direct fit into the fuel cage.

Thanks mate. It sounds like those injectors flow around 600cc. Do you know what sort of duty cycle your pump and injectors are at with the SC setup?

(anyone local chime in on what their E85 experiences have been with the SC and fuel delivery?)

Expect 50-60%, but it depends on what boost you will run and fuel pressure.
