will FIC 1450's get me to 35psi on e85 without max. my IDC's?

[johnmarines]

Was wondering if my current FIC 1450's will be able to get me to around 35-37psi without maxing my IDC's. Im debating on upgrading to some 2150's but I would think its overkill. My Mods are the following

Built bottom end
L19 Head Studs
Precision 6152s
T3 Shearer Fab Turbo Manifold & O2 Housing
jayracing fuelpump Pro Series 342 Fuel pump(rewired)
kelford 272/272
3" GM mas
GM MAF cable
linkv3
JMF manifold
>>>>>E85

Only one way to really find out and that's to go out and see what happens. I think you should be fine though.

Im just going to bite the bullet and go ahead and pick up some 2150's....

There's a chart in the tech section showing what amount of airflow the the injector can support on e85, just read in there and give yourself soem room for error.. I have 1000's and make 438hp running them into the 85-88% IDC (although theys should support more in a perfect world or according to the chart, but there's also a note in that thread that there's a 15% error margin or so IIRC)

Just use the turbo's map and figure out your airflow goals to pick injectors, you really shouldn't go oversize if you don't have to, going too large only kills feul economy worse than what you're already setting out to do, and gives more idling issues if you don't have really good management to control them (and no matter what management no injector likes to open less than 2ms per pulse and become erratic and won't remain consistant at those openings for less than that) On my 1ks, i'm idling at 14.5:1 and they are getting a pulse width of 1.20ms
