Walbro, 550's enough for 10-11 psi?
Is just a Walbro and the stock 550's enough to support 10-11 psi and 250 FWhp? (With a, S-AFC and FMIC)
Does the Walbro 255 raise fuel rail pressure enough to effectively increase the rated CC flow of the injectors?
Thanks
Dumb question, I know... I'm an N/A guy!

I know they're good for 10psi on a stock IC and exhaust. I pulled 195HP on a Mustang Dyno.
We did hit 12psi briefly and the afr didn't go past 12/1. At 10 afrs were in the low 11s.
You said something about being an NA guy. This isn't a boosted NA engine is it?

The new engine is getting lower comp 9.5:1 rotors... it's something.
By meaning I'm an N/A guy, I mean that I know pretty much everything about N/A setups, but I don't know much about the specs and limitations of turbo cars... I'm learning!
Ya, A little richer mixture will be riequired to further prevent detonation than a regular comp. motor...
