marinized v12 running 2 x 808's

[vlad01]

it might slightly, The1 should be able to comment on that.

Out of interest a mates car I tuned he's running blue tops. Had them in the high 80's duty cycle so we wound the fuel reg up to 3.5 bar (52psi off top of my head) injector data still seemed fine this was early on in the tune so any minor injector data mismatches could of been made up for in the VE table anyway. Think it finished up at low 80's still anyway once tuned but the AFR's are solid as it came up good. MANY hour's went into that tune. It's in the 12P custom tune thread VK355 bin.

I am using the vn v6 pressure reg 0 280 160 529 is there a direct replacement @ 3.5 bar

[Dylan]

Wonder how the VY V6 one goes. Think either VLAD01 or The1 has a thread on that.

Different pressure might gain you a little extra but depending on the flow/rpm you expect to need might be better to get some known spec injectors with headroom like deka 60lb. Dead time specs by voltage are on this site. Can provide link.

[jenko]

no that's a pot type regulator

[kojab]

3 bar

Are you logging the fuel pressure?

The 3 bar you mention is that at near full load

[jenko]

full load is 3 bar

Bit the bullet and have ordered some 0 280 155 715 24lb injectors ,I was wondering if these specs are what I need ,I can work out the battery bias ,but whats the rest of the figures and how do they relate to TP ?

[Dylan]

FNPW offset is what yu need think 12P calls it battery bias or similar. And just 0 out the ms add on table.
