Question Hertz and its affect on noids

I'm wondering if someone can explain what changing the Hertz on your nitrous controller does to the solenoid, especially in relation to pulsing the noid?

I've been told to try different Hertz settings on my controller when progressing the noid at low percentages, and that different noids, like a trashcan, require different settings than a standard solenoid. I would like to have a better understanding of the impact of changing this Hertz value.


Thanks
Kevin

Well hertz is a measurement of cycles per second, if you didn't already know that. Now from my experience the smaller the plunger the higher the hertz can be and the smoother the delivery of nitrous or fuel will be, now with the trash can noid the plunger is huge and can't cycle as fast so the plunger doesn't even get a chance to open till higher percentage on the progressive. Best thing to do is to bench test each noid using the same psi and voltage to see what works for you. Hope this helps.

As mentioned above, the plunger size is a part of it. But as mentioned a trash can solenoid works best at slower hertz. One of the other main reasons is the coil size. When hertz is to fast, the coil cannot saturate with enough power to operate and move plunger. When you slow it down, the on and off periods become longer in time, hence better control and reaction..

So steve since you have to run a lower hertz with a larger plunger thus less opening/closing cycles per sec. do you then have less adjustment with a trash can noid on a controller and if so is it a noticible one ?

Well the bigger the noid the harder it is to tune it to progressive it softer.
It's harder to make a 400 hit leave softer with a trash can noid then it is with a smaller noid if your using a progressive box.

If you want best peformance, run a 16v system. It mostly has to do with the energy the coil has, vs the force needed cycle the plunger. The more energy the better. Some small solenoids don't have the coil strength to get pulsed properly. The lower the frequency, the "better" they mechanically operate, but ideally a higher frequency makes the system better theoretically.

Might want to check the thread again. You haven't provided any "cutting edge knowledge".

It seems everytime you enter this forum it's to throw a SALES pitch!

No you still have the same adjustability. Your range of percentages and time is still there to work with.. It will actually just be more responsive to changes from what I see.. SJ

I do not agree with this statement. You'll be really surprised I think if you just slow down hertz and try it.. SJ

Steve are you responsible for removing my posts on this thread or have you condoned it or are you not aware of it.

In your instructions, it states that posts would be deleted only if a persons 'main' aim was to promote their products and yet my main aim is to educate and pass on my extensive knowledge on this subject. I made NO mention of my own products, I didn't link to any of my products and I don't have a HUGE BANNER with contact details in each of my posts, as say Monte does, so can you please explain why my posts on this thread have been deleted?
