Default Meth Nozzle Flow Test

RESULTS UPDATE ON POST 31


I figured most of you guys might want to know this. I set up a small test to see how adding another nozzle to my kit would behave. I have an alky control kit, use 100% meth, and currently have 2 14gph devils own nozzles with the system set to come on at 5psi. Those of your familiar with the kit know there is a controller, ranging from 0 to 8, to adjust the meth. I took measurements with 1, 2, and 3 14gph nozzles at referenced pressures of 10, 15, 20, 25, and 30psi using compressed air at the controller settings of 1, 4, and 8. This would be the same as the boost psi you run.

I did this with the engine off so obviously the voltage is a little lower than it would be when driving, but I had a charger on it and it was a steady 12v through the testing. I did not touch the initial or turn on setting, just messed with the controller and added nozzles.

Here is my nozzle setup, got this cool nitrous distribution thing with 4 ports on the other end. Feed line from pump is -4an as are the lines to the nozzles.

So once I measured the nozzle pressure at all these points I put it in excel where you can do some cool stuff with it. First I correct the numbers to nozzle pressures by subtracting out the intake pressure. Same reason why injectors flow less with a forced induction setup, all the nozzle cares about is the pressure across them, not the total pressure.

So once that was done I came up with the graphs below, one with the controller set at 4 and one set at 8. I didnt bother graphing the 1 setting but its lower than 4

The most significant thing you see is the diminished return from adding a third nozzle. The single 1x14 is what you would expect with the nozzle being close to its rating and relatively flat, especially with the controller on 8. At 25psi, going from 1x14 to 2x14 increases meth flow by 63%, but only 6% when going from 2x14 to 3x14. Clearly the pump is maxed out.

With the controller set to 8 the pump is giving it all it has over 15psi so you see a very linear decay like you would expect. You can control the behavior below this point by adjusting the "initial amount" and "turn on psi" dials on the controller, but once the pump is maxed thats all there is.

And because I know someone is going to ask for it, here is the chart in lb/hr using 6.6079lb/gal as the density of methanol.

If you read my writeup on fuel pressure vs. flow (Which I highly recommend if you havent, https://www.performancetrucks.net/fo...p-flow-510434/) you know we can estimate the power potential given a flow rate of fuel. Using a BSFC of 1.0 (optimistic for methanol), the rating in lb/hr is the same as the horsepower it is able to support. For example, with 2x14 nozzles at 20psi of boost you can support about 138hp on the methanol fuel source. This says nothing about the anti-knock properties or cooling, just the amount of power you can get by burning the fuel.

So what now...I am going to call Julio tomorrow and see if there is a way to get some more sauce out of this pump or if upgrading the lines to -6 will help any.

I attached my spreadsheet if anyone wants to look at it.

That is alot of meth! does your pump have an allen screw to adjust the pressure on one end?

also what kinda pressure did the pump put out when spraying?

Not sure about the screw but the spreadsheet has the pressures in it. Most i saw was 100psi, it behaved like an internal limit.

Bout the same results Jarrett has had with his unorthodox methods of testing lol.

You should send this to Julio. I'm sure he'd appreciate it.

Nice write up Atomic. What was the reason for adding another nozzle? Why not add another pump and add two more nozzles?

Nice wrote up.
Probably going to need another pump. Like you said. 3 nozzles looks to have maxed out the pump.
Wonder if you loose any burn rate with lower pump psi more flow if the droplet size is larger ???

Its a lot easier just to add another nozzle, and I didnt want to mess with a second pump due to plumbing. Part of my plan to keep from damaging the head again is more meth.

I really like the devils own nozzles since they appear to atomize much better than other nozzles ive seen even at a low pressures. I would guess the difference between 50 and 100psi is negligible given the turbulence and distance to the cylinders.

this may be a dumb question, but why do you need multiple nozzles?

why not just one BIG nozzle? atomization problems? just thinking out loud

15 is the largest anyone makes I think, and yes atomization. The bigger the nozzle the more pressure you need to make it atomize better, and since the nozzle flows more and you have to run a high pressure you need a bigger pump and so on.
