let me know how they go.
Not the best pics, but out of interest here's different injector images you can tell stream vs some breakdown/atomization of the fuel, Bosch 36LB L67 4 hole, FoMoCo 39LB 6 Hole

Re: Injector Flow Testing Data
6 hole definitely looks better. More fine mist.
I would imagine injectors like this would help some with bigger cams.

Re: Injector Flow Testing Data
Just take my damn money.
A Set of 6 matched 39LB injectors and what ever adapters for the L67.
If it buys me 8-15% fuel economy in the long term, I'm in.

hahaha they are still a lot better spray than my deka 80's The1

It'd be interesting to see what difference these injectors would make.ralcool wrote:Just take my damn money.

Re: Injector Flow Testing Data
I'd take it this is at 100% duty cycle? It'd be interesting to see what they look like when pulsing at more conventional duty cycles although I guess it would be a bit harder to capture.The1 wrote:Not the best pics, but out of interest here's different injector images you can tell stream vs some breakdown/atomization of the fuel, Bosch 36LB L67 4 hole, FoMoCo 39LB 6 Hole

Did you experience a problem with your 80lb deka's. Were they new?Holden202T wrote:hahaha they are still a lot better spray than my deka 80's The1

Re: Injector Flow Testing Data
they work perfectly fine 
I got The1 to clean/flow test them for me, and there was a comment from VL400 about them being garden hose fittings, not far wrong!
these babes in my 202 with methanol and 22psi boost (fuel rail 40psi at idle with 1:1 rising rate reg) are on about 90% duty cycle

Re: Injector Flow Testing Data
Great pix. Assuming your not running sequential so with 90% duty cycle and methanol and 1:1 rising rate reg it's working well.

Re: Injector Flow Testing Data
Got to be basic physics really, when you try to pass such a large quantity through such a small orifice in such a short time proper atomisation just isn't going to happen.
IT would be interesting to see how well the injector atomises the fuel when it's running in the engine as there is a high speed air stream passing the injector which will help take the fuel away. In that pic the fuel is effectively backing up into itself as the high speed fuel stream is hitting stationary air.
