305cc's max out at?...
ok. PLEASE don't **** on me for this thread.
I've read the faq, and searched as much as I could but I need to jump on some injectors before they get sold and need a question answered that I can't find.
What are 305cc injectors good for? At what HP do they max out? 305cc is rated at 43.5PSI, something the guys over at RX7club do is bump the base pressure up a bit to say 48PSI.
Goals for my car is 220-230whp. Running MegaSquirt and a homebrew GReddy kit.
Again, yes I know the information is out there somewhere however I would like to buy these tonite and can't seem to find definitave information.
Or should I just go with 1000cc injectors? I hear they idle fine

i'm suprised i didn't think of this in my last post, but there is a good calculator here to give you an idea. It will also tell you what fuel pressure will do to your flow rate. Fuel Injector Calculator from WitchHunter Performance

If by 305, you mean the Supra 305s that tend to flow at 320, you'd be just shy of your goals. I'd find some RX8 420 cc injectors, which will give you good economy and headroom.
Alternatively, the 305s with a little bump in fuel pressure would also work.

I can tell you 360cc's won't be good unless you up the fuel pressure. Give yourself headroom, it's not that big of a deal to do it now but it is later.
BTW are theses 360's 323 gtx ones?
Edit: I was running gtx 360's at stock gtx fuel pressure (38psi) and they wouldn't cut it on a gt2554 sized turbo at 14psi boost. With a good sized intercooler I had way too much heat and couldn't get it rich enough to not melt/ otherwise damage pistons at 38psi fuel pressure (so I upped it).
