Best Fuel Injector size?

[53BigDog]

Hey all, need a little help on choosing a new fuel injector size.

I have a .020 bore with 9cc pistons and Stage II port and Polished PI heads. I also have a MAC CAI and a 90mm MAF.

I am staying N/A, no power adders.

I was thinking 24#

what do you all think?

24#s would be the smallest I'd go with on a high-output, normally aspirated 4.6.

I would go with 30s

go with something 30# plus in case you go more aggressive NA and just detune a bit on the fuel side?

Right now, 30's can be had fairly cheaply....I'd go with them.

you could even keep your 19's and still be ok....I was putting 307 rwhp and 340 rwtq on my 19's with a dyno tune with no issues...only went up to 42's now with my blower..

I would say 24, especially if you can get them cheap. Too bad you can't use the 05+ style - those are real cheap.

just save the money and you will be fine with 19s.
