hey guys is there a way to increase the size of the holes in our nozzles, does anyone know what size whole is equivalent to what HP level, who and or where can i find more info?

 

exdrude hone them.

stock 2nd GEN injectors - vary depending on model but all are 145° injectors
non inter-cooled 1st gens had larger piston bowls and used 155* injectors

49 state 160/175 hp - 5x9 .000318
180 hp- 5x9.5 .000354
160 hp cpl 1863, (actually a 180)- 5x9.5 .000354
all California 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 155° - 5x12 = .000565
435's - avail in both 155° and 145° spray pattern 5x014 = .000769
7-hole are 158* spray angle, very rare bosch 148*

DDP stage III (90 hp) = 50 LPM 155° - 5 hole extrude honed <5x12 270 bar
DDP stage IV (140 hp) = 66 LPM - 5 holes smaller than .0135 270 bar
DDP stage 4 plus - 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


custom injectors

5x.012 = .000565
5x13 = .000663
5x14 = .000769
7x10 = .000549 (24v conv injector 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

industry injection 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)
