Default Which injectors for 550rwhp?

They are for a NA 422..Redline set to 6500rpm.Shooting for 500-530tq

I was thinking FMS 30's or 36's...The fuel pump will be upgraded too.

Thanks

That's the exact goal I have N/A for my motor. 36 lbers would do it, but I went with 42 lbers.

I figure true 42's rated at 58psi would be good,but not FMS 42's rated at 42psi.I have no problem tuning in any injector,it's just that I don't want to over inject it..

Exactly. My 42's are rated at stock fuel pressure.

42#@3.0bar are probably cheaper to get (steeda.com/ebay.com) than 36# @ 3.0bar (running at your 4.0bar) ...

theres an abundance of 42#'ers out there due to the mass production use in the lightning/cobra, and the fact they run out of juice quick and have to upgrade to 50#.

I paid $100 for 4 42# (vw use) last time at the ford shop. I guess i coulda bought me.

$200 for 42# lime tops off the svt m112 lightning, not bad., not great, but not bad.
