not such a big jump

yes, like you said, 7x14 is gettin up there

stock 2nd gen inj - vary depending on model but all are 145° injectors

49 state 160 hp - 5x9 .000318

49 state 175 hp 5x9 .000318

180 hp 5x9.5 .000354

160 hp cpl 1863, (actually a 180) 5x9.5 .000354

all calif trucks '96-98 were 180 hp = 5x9.5 .000354

215 hp - 5x10.25 .01025 .000412


300's and 330's same size - 4x12 = .000452

370's - 5x12 = .000565 155° spray pattern

435's - 5x014 = .000769 avail in both 155 and 145° spray pattern



ddp stg III (90 hp) = 50 LPM (liter per minute) 155° 5 hole extrude hone inj <5x12 270 bar

ddp stg IV (140 hp) = 66 lpm - 5 holes smaller than .0135 270 bar

ddp stg 4plus - no longer avail now considered comp waiver must be signed to obtain

ddp comp = 73-90 lpm depending on application same for pop

all four start out as 155° marine nozzles and are extrude honed

the flow numbers (lpm) i posted is what was printed on boxes that i received from ddp

there are posts on other forums that vary slightly with these numbers

measured the holes myself (.0135 gage would not go in a stg 4 ect)

have not used 50 or 75 hp ddp inj - have no idea what size the holes are



custom injectors -

5x.012 = .000565

5x13 = .000663

5x14 = .000769

7x10 = .000549 (24v conv inj are usually 7 hole)

7x12 = .000794

6x13 = .000795

5x15 = .000882

6x14 = .000923

5x16 = .001005

6x15 = .001059

7x14 = .001077

5x17 = .001134

6x16 = .001206

5x18 = .001272

6x17 = .001360

5x19 = .001416

6x18 = .001526

5x20 = .001570

ind inj super dragon flows (10 hole) - 5x10.25 + 5x18 .001684

6x20 = .001884

5x22 = .001900

5x24 = .002261

6x22 = .002280

5x25 = .002459 (this is what some refer to as a true competition injector)


*i figured out the csa (cross sectional area) for ea injector. those numbers are in bold

if you want to figure 24v stuff or something that is not on the chart use r² x pi x # of holes

take the hole size divided by 2 times pi (3.14259) times the number of holes

i guess i havent heard much about a 7x13 but something to look into but if i step up to the 2.8 class next year ill prolly just say this is what i got for air and fuel i need a injector and see what weston comes up with. The only concern i have is spraying out of the bowl on my truck once i do the ppump swap but i think the 150* sac nozzle and machining the injector to drop it further into the bowl will help alot so i can pull off more timing but not sure if it will have any affect on streetability when running around 22*.

dude - i have been running 21° (towing 22k n all)

never gonna run under 20 again

forget the sac and try to get some blank vco's


*(so you can tighten em up and run even more)

[kjpcummins]

how tight can a person go with spray angle ill have more info on the nozzle next week he said something about just having them make a whole new nozzle

thats cuz he cant get the nozzles (sac style)

if you start off with a blank you can go tight as required

weston has a forumla - figure out max timing for any spray pattern on any piston

know what i mean? your bowl is x you want to run x degrees of timing = you need x spray pattern to still be 100% in the bowl


*far as this chart and street injectos goes tho with the stock 2nd gen piston (actually there may be 2 different bowls from 94-97) you can run up to 26° of timing with a 145° spray pattern

18° max with the 155 industrial stuff

[kjpcummins]

with the ho engine 57mm piston bowl its fairly easy to spray out. I see what your saying it will be a few months prolly but we'll see what happens.

Are the MarIne injectors less than desireable on the street with a stock turbo. Or is there no point on searching for some 370s till I get more air?

Marines arnt really desirable at all. For what you get you would be money ahead in milage alone to get a good set of injectors.

so for a set of 435's with the 145 degree pattern where would one order a set?
I assume theres a bosch part number?

[flubyux2]

Yeah, that's what it's starting to sound like. What's this I've been hearing about one of our own guys who builds injectors, Weston or something?

weston is not building 12v inj anymore

how much air your charger moves wont be as big a factor as the restriction it creates on the ex side

someone needs to make a chart

with the pump maxed but not benched x injector requires x air

[flubyux2]

hey don, whats the low down on sac-less/vco nozzles? do people retrofit them onto stock injectors and modify them?
