What do I need to boost up too 18 psi?

[TeclipseFTW]

ok, so what psi will the 190 support on a big evo III 16g with 550cc injectors?

Using that information coupled with flow rates of the 16g will tell you what the max psi you can run based on injector flow and fuel pump flow.

so this is a little confusing...


Injectors

390cc @ 100% IDC will support 27.99lbs/min
390cc @ 80% IDC will support 22.39lbs/min

450cc @ 100% IDC will support 32.30lbs/min
450cc @ 80% IDC will support 25.84lbs/min

550cc @ 100% IDC will support 39.48lbs/min
550cc @ 80% IDC will support 31.58lbs/min

580cc @ 100% IDC will support 41.63lbs/min
580cc @ 80% IDC will support 33.31lbs/min

650cc @ 100% IDC will support 46.66lbs/min
650cc @ 80% IDC will support 37.32lbs/min

Fuel Pumps

Walboro 190lph

10psi = 46.48lbs/min
11psi = 45.89lbs/min
12psi = 45.26lbs/min
13psi = 44.58lbs/min
14psi = 43.86lbs/min
15psi = 43.09lbs/min
16psi = 42.28lbs/min
17psi = 41.43lbs/min
18psi = 40.54lbs/min
19psi = 39.60lbs/min
20psi = 38.62lbs/min
21psi = 37.60lbs/min
22psi = 36.53lbs/min
23psi = 35.42lbs/min
24psi = 34.26lbs/min
25psi = 33.06lbs/min

Walboro 190lph (Rewired)

10psi = 60.68lbs/min
11psi = 59.85lbs/min
12psi = 59.01lbs/min
13psi = 58.16lbs/min
14psi = 57.29lbs/min
15psi = 56.40lbs/min
16psi = 55.49lbs/min
17psi = 54.57lbs/min
18psi = 53.63lbs/min
19psi = 52.67lbs/min
20psi = 51.70lbs/min
21psi = 50.71lbs/min
22psi = 49.71lbs/min
23psi = 48.68lbs/min
24psi = 47.64lbs/min
25psi = 46.58lbs/min

Does this mean that I couldn't run 25psi with 550cc injectors and a 190 walboro pump on my 16g turbo?

Do these numbers take into account different turbos?

Money is an issue. but, i was just going to tune with the SAFC II because those are available for 200 or so."

Save another month and get Ecmlink lite because you'll not regret it. You’ll also need a wideband. Turning up the boost- is playing with the air fuel ratio by nature, you must have that wideband. I went with an innovative LC-1 because it was cheap but not too cheap. I recommend the link because, its like $150 more; the benefits of running and saving for the link outweigh the costs. Oh and you will need to upgrade your maf to fix fuel cut; i went to an evo one.
Dsmlink allows you to select various mafs.
You should have a front mount intercooler. I do not run one. I have however put the boost to 18. I do not have stock injectors, I have hand me down rc 550's and a rewired 190, so a hundred sixty bucks of parts. Get a good boost leak test, and make sure everything is sealed up good. I've had to crush the bov to hold the boost in more- it still leaks. *I must get a punishment racing fmic kit*.
