60lbs. Depends on the base psi your calling it.
60@ 43.5psi
Or
60 @ 60psi

We have a flex fuel 6.2 dyno'd 610 with (stock Flex fuel injectirs)
54lbs I think is what they were called.

If that's your plan then get a set sized for your application that will let you achieve that power goal and give you some room .

I have 60#ers but without the meth I don't think they would have cut it .

Also mine are Deatchwerks plug and play. I suggest talking to them and seeing what they have for setup . I'd rather have plug and play then re-wiring /spacing if it can be avoided.

i have the same injectors as TIM Z

71# at 4bar

$450

SD60's are fine for 600, they are actually 72's at 4 bar (58psi) I made 800 hp with them at the track, maxing out the 340lph fuel pump but was also running meth with a single 15gph nozzle. SD60's and a Walbro 450 would be my recommendation for 600 even with out meth.

Not to thread jack, but this is the issue I'm having. Last 2 months I can't seem to get my divers rear injector to seal. I'm running the siemens 80s with a ls1/ls6 fuel rail and its leaking like crazy were the injector meets the rail. I got the old style o-rings installed and just picked up a set of new style and some ls6 vette o-rings see if it will seal. Idk what else to do?
