Fuel Injector comparison, stock vs Ford vs Volvo

[fishEH]

So I have a set of each, all used. Decided to do the ghetto clean with brake cleaner and a 12v battery.


I was surprised at the difference in spray pattern. The stock Rover D1 injectors basically dump fuel out like a garden hose.

The Ford were better. #0280155700

And the Volvo seemed to have the best pattern of all. #0280155746

Great. This needed to be done. Did you try multiple D1 injectors? Maybe you got a bad one.

I did the same process with 8 of each style. Results were consistent.

Love the bench. First look I thought you had this going on in your kitchen. Somehow Volvo seems to have no problem with injectors needing to be flushed or cleaned. Interesting the spray pattern is so much better too.

The pattern on the Volvo injectors looks like it is supposed to spray the back of 2 intake valves.

I've done fuel injector "upgrades" on other motors and never really saw much of a difference aside from a better idle. I'm sure there is a difference, just don't know if you can really tell. Def cool to see the different spray patterns.

I used the Ford Motorsport injectors in the P38 when it had a stock motor with just a cam in it.
Hard to tell the real difference as the Rover ones were no doubt pretty worn, but the idle did smooth out.
Worth the money if you are needing injectors anyways, otherwise....

Does the engine really care that much about the spray pattern?

Efficient combustion does

When I first opened my old shop, I took a bucket full of injectors, a five-gallon pail, a fuel pump and a battery changer and set them up to test fuel injectors.

I went through to find those that leaked the least

While I know I posted it here, it was probably before the crash that wiped everything out (but, it was after Kyle banned me so maybe not).

Either way, I will someday build a real injector test bench as I now have an injector pulse generator that will drive four injectors at once. However, the Chi-Coms are now offering complete tester/cleaner setups for less than $500 delivered.

Now, I have had really great success with GM injectors but wish they had some lower flow-rate units as those I've used were just too rich. Truck ran great, but was hard as Hell to start when warm and fuel economy was horrible, but oh my did the truck run well!
