Injector size

[clipto]

Of course I have been searching, but maybe it's personal opinion. But minus the fact of yes just get the biggest injectors and do it once, but for 350hp range on a evo 3 16g and I plan on staying 350hp for a long long time, what injectors would be most efficient for maxing out the evo3 16g? I hear all kinds of different size range but cant find a injector to horsepower chart. Looking to get the right size enough to max out but not totally maxing out my injector duty cycle.

You'd be happy with a set of FIC 850's. I was running my T04B at 27+PSI on a set of 850's. Never had an issue.

That's funny I was thinking right in the 850's range. Whats your idc at?

Do you still plan on tuning with the SAFC listed in your profile? If so, you can't go above 660cc without having tuning issues.

You can also check out this tech article. It'll tell you how much airflow each injector supports for pump gas at 80% and 100% IDC's.

Good catch! I certainly did not check his tuning option.

Hehe, yes I have link v3 full, just need to install. I Should of stated that but of course I have well used my safc its been good but its definitly maxed it's life out. Oh and thank your for the link great info in there, couldn't find that article when I ran through the search. Must have been my bad wording. In that article what lbs flow for evo3 16g am I looking at?

 

[snowborder714]

I seem to remember Evo 3 16g's maxing out around 44 lbs/min.

So from looking at the chart 850's at 80% seems to be right for this setup? It shows at 48.8%

 

[XiKeiyaZI]

850's will be fine. Haha.

 

[snowborder714]

That's the smallest I would go. If it were me, I would never run my injectors over 80-85%, and if you ever plan on going with something bigger than the Evo 3 16g, then you aren't leaving yourself much wiggle room.

I always recommend people to get 1050-1150's if they're not going for really big hp. Yes, that's a lot of injector, but you will almost never have to upgrade.

^ Brian just loves to overcompensate - But he's right. 850's will be fine on a 16g, but if you go bigger then you'll want a little more room. 1000cc+ Injectors would handle quite a bit more work.

 

[snowborder714]

The other thing to keep in mind is if you ever plan on running E85 (if you have it around you). You'll need a larger injector to do so.

Was thinking 1000's too, and I don't wanna run a high duty cycle. 850's is minimum it looks like, but if they have high duty cycle I would rather play it safe. Some FIC 1000's look like they flow nice numbers.
