Injectors

Ok so I have just bolt ons really on my 04, mods in sig. Me and my buddy were logging the other day and my idc is peaking at 80% under wot. Do I have enough injector to support a cam heads and about 150 shot? Prolly not, so how big of injectors do I need?

Anybody?

for full bolt ons, 42s are usually plenty. Think they will support around 5psi. For a shot, you might just want to go with 60's to be on safe side.

so would allen's 48 pounders do?

might as well go 60's

K cool

I spray 150 on my stock flex fuel injectors... with full bolt ons my IDC is around 65%.

yea but i plan on putting a decent sized cam, heads, and a proflow mani too, so i dont think those stock flex fualies are going to be enough. Arent they like 30 lbs?

anything above 50 should be fine, but 60s are insurance for future mods, plus a aftermarket fuel pump

k sounds good
