like my title asks, should the nozzle be spraying like a FINE mist, or should it be a harder spray that almost seems to pulsate?

 

what size injector are you using?

 

as long as its still a spray..and depending on ur hp/cooling demands...as long as its not coming out like a water fountain

 

not sure....when i bought it from coolingmist i had to give him my estimated hp/tq and he was supposed to match it with the correct nozzle....i also suggested a 3gph nozzle as well since ive read that that is what most people are running. is there a way to tell?

i figure, when my car is being pushed that hard anyway, there is plenty of air passing through the intake and therefore the spray is instantaneously getting pulled into the supercharger, therefore making it almost necessary to have it spraying that hard in order to keep up with the airflow and gain the benefits of the kit....but still...seems like a lil much...


again, should it be a FINE spray? or heavy spray?

 

Rodney over at AIS told me he recommends 6gph for our cars but I've never seen one in action (Bout to order mine this week) so did you put on a 3 or what size is the issue?
And how much of a spray are we talking?

 

3gph is fine to start with.

 

Run a number 6 nozzle with a 50/50 mix and have the engine retuned for it. You can run a number 3 but we found it was too small and did not provide optimal results. With these type of superchargers (positive displacement) and injecting pre-compressor we found you needed twice the normal jetting as centrifugals and turbos because much of the mist was instantly evaporating as it hits the hot rotors and tries passing through the rotors and the case. Run a number 6 nozzle if you want to achieve the full benefits.

 

thanks! but would a 6 gph nozzle be a heavier/thicker spray and less of a mist? if so, it seems that that is what coolingmist supplied me with.... like i said before, it sprays heavy and reasonably thick in very quick spurts

 

3gph should be a real fine mist and is what you should start with.

 

im running 2 6gph nozzles

 

all the mists from a nozzle should be a mist. the more gph, the more foggy, the less gph, the less foggy but both still a mist.

this video is 5gph, so compare it to that

there are also a ton of other videos on youtube by coolingmist, just search, "coolingmist"

 

Just so everyone knows. Raven SS is going to be making somewhere in the neighborhood of 400-450 horsepower running the TVS supercharger on a built engine. Additionally, he's running the fully adjustable Stage 2 progressive system which allows him to dial flow out through the controller rather then changing nozzle tips. This allows him to run a slightly larger nozzle(s) arrangement since he's not limited to adjustments only at the nozzle.

Don't want everyone to be confused why Raven SS is running two number 6's. That would totally throw a wrench into the mix.

not all motors move the air needed to support 6gph. start small.

 

We've found stock 12.5 psi engines to run number 6 nozzles just fine with a 50/50 mix. We no longer recommend number 3 nozzles as we found out it was not providing the full benefits. If a customer wants to run a number 3 nozzle thats fine. We simply will not guarantee the same results.

We have looked into this extensively. Not just with the Cobalt SS Eaton's but many other makes of positive displacement superchargers. Due to their inherit design and substantial surface area, these superchargers will require basically twice the jetting as a centrifugal for a equal horsepower range and boost setting.

This is merely are findings and suggestions. You do not have to follow our recommendations.

lol sorry about that

 

Oh no. It's not a problem at all. I just thought I would elaborate a little since your application is unique. Members would be very confused then as to what size nozzles they can run.

 

this is insanely easy to do at times



im good at it

 

I started by running the 3gph nozzle and was still getting knock, I then read the post above, switched to the Devils Own M5 (5GPH) nozzle as mentioned and the knock is gone, and run cooler...thanks for the advice..worked for me

 

Good for you! Happy to be of help.
