Postby DTanklage » Sat Oct 20, 2007 8:08 am

stock 1st gen inj - 6x.009" = .000380" total cross sectional area

non ic inj - 4x.013 = .000531 ( larger than ic inj)

2nd gen inj - these vary depending on model

160 hp- 5x .008

175 hp 5x .009

330's - 5x.011 = .000474 (20% larger than stock)

2nd gen 370's - 5x.012 = .000565 (48% larger than stock)

ddp stg IV = 55 LPM (only 10% larger than stg III's) 5 holes <.013

ddp stg 4plus = approx 65 lpm

ddp comp = 73+ lpm

pods - 4x.015 = .000707 (% larger than stock)

2nd gen 435's - 5x014 = .000769 (twice as large as stock)


custom injectors -

6x13 = .000795

5x15 = .000882

6x14 = .000923

5x16 = .001005

6x15 = .001059

5x17 = .001134 (300% larger than stock)

6x16 = .001206

5x18 = .001272

6x17 = .001360

5x19 = .001416

6x18 = .001526 (400% larger than stock)

5x20 = .001570

6x20 = .001884 (500% larger than stock)

5x22 = .001900

5x24 = .002261

6x22 = .002280 (600% larger than stock)

competition p-7100 injector 5x25 = .002459 (freg↓n huge)

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


please post the sizes for the tips that are in question (if you know them)

thanks

ps - that should be good for about 800 hp if your unit is big enough to burn it all

forgot to ask you what size jets you are running with the stg 4's???

A= pi r squared

Area of one hole * number of holes = total area

3.14*((1/2 diameter)^2) * number of holes


For example, stock 6x.009:

3.14*((0.5*.009)(0.5*.009)) * 6

= 0.000382

Or if you wanted to be more accurate you could use 3.14159265358979323846264338327950288419... for pi. :P

when i figure them i find the Rsquared part first, then multiply by 3.14159, then multiply by the number of holes

iow for 8 by 11 ▬ 11/2=.0055; .0055x.0055=.0000302; .0000302 x 3.14159 = .0000948; times # of holes 8 = .000758" (i drop the 4 and only go out 6 places)

FYI: ref ~ The DDP4 1st Gen injectors.

I talked with the fellas at DDP today regarding the DDP4s for the 1st gens and had no luck in getting the actual orifice size. Also, the older versions run five orifices where as the newer now run four orifices.

they are small

much smaller than 014

all i know is that they flow 55 liters per minute compared to the stg III's 50 lpm - and both are smaller than pods

with the ve being such a small pump i dont know why they didnt take em out a ways further and make them bigger than pods?

its not like we can make the pump push a bunch of fuel to make hp

we cant

have to do it with big injectors
