Injectors Spray Patterns

[Dillz]

Me too, when some people are paying over $1000 you would expect them to be matched to the ports. Wonder if Nizpros are still twin?

By degree of the cone would say 30 degree in the 60's be favoring one side more where as 5 degree in the ID's be hitting the middle more? Is that how it works?

yeh I had a fair idea this is where it was heading the partial throttle response and even idle performance only reason I asked was because I wasnt sure if toads was hunting for back to back testing of injectors in same same condition but different oriface and or spray patterns at wot, I was thinking at wot there would be negliable differances but THIS is where experiance will say otherwise.

as in the 80lb deka isnt the best choice for the 4.0 and can be a *beep* to make idle right because of the single and very narrow spray pattern but at wot the results seem to be as good as a dual cone spray pattern but only a decent amount of r & d would show this up?

ratter what have u seen?

this may be b/s but I would think injector spray pattern would be something the n/a side of things would be greater affected by

thinking thinking

^^^^ I like this jet.

Maybe under boost I would say the spray pattern of the single spray ev14's makes fark all difference as long as the cone width is well.. wide, as is 15+pounds of boost helping the fuel find its way.

However, in vac and low boost situation the twin spray would really be beneficial. especially when cruising at 100kms.

on the falcon with the bridge there the single narrow spray pattern of a deka may have an effect that might seem weird and very unconventional but the pulse of high pressure fuel hitting a point almost a fork on the road may have a greater way of disrupting the fuel so its more in a mist form as it enters the pot vs 2 squirts entering more as a compact stream..........................this is just a thought as the more broken up the fuel and more mixed with the air leaves an area in the cylinder with a maximum air/fuel mixture vs a clumped air /fuel mixture ? this may be the nitty gritty though?

not entirely

get a spray bottle and set to mist, then spray a fine mist into the air, note the very fine mist.

Now spay with an empty stubbie in the centre of the mist about 30cm from the nozzle, note how the mist bonds to form larger droplets once it collides with the stubbie

[JETURBO]

all I heard was stubbie

what beer we drinking lol?

yeh I hear what your saying I was just going outside the box on the thought process as many tuners have dramas getting typical types of injector to perform and others seem to have no trouble at all, there must be an answer to this and experiance is the key like everything in life, but spray patterns must be either a huge factor or nearly no factor in this?

how bout a dyno run with a dual spray injector then another dyno run with the injector turned 90 degrees? ( so it hits top of bridge and bottom of entry runner)

this could of been dyno wogs secret to get 300 out of stock squirters lol

that makes sense - if the cones are set on enough of an angle that the fuell will hit the runners.

would be easiest with stok injectors, no? can't argue about tuner setting them up wrong then

Lol good analogy till the end, I was thinking now put it on stream and squirt it at the end of a credit card. Not fine mist is the result.
