Aquamist 2d - what size jets to use on a Stg3 car?
I've searched and searched and only found every possible answer. I've read results from a pair of 0.4mm to a pair of 0.8mm. Not all of those are K04 cars, and some of those are 1S systems.
So, does anyone have this setup, or recall what jet sizes would work on a similar setup for comparison purposes.
Somewhere was stated to have the WI be 10-15% of total fuel flow. If the RS4 injectors flow 481 cc/min, then 6 of those flow 2886 cc/min.
10% of that is 288.6 cc/min
15% of that is 432.9 cc/min
The chart below shows that each 0.5 mm jet flows 200 cc/min on the 7bar pump, and thus 400 cc/min for the pair. This seems to be a good choice assuming the constraints above are true for the 2D kit.

But I thought Jason/ND was running dual 0.8mm, but I can't find that anywere in the archives, so perhaps I'm making that up.
Anyone have other info to help?

yeah, see here I see dual 0.8mm ....
maybe that "10-15%" wasn't for the 2D system<ul><li><a href="https://forums.audiworld.com/s4/msgs/1304045.phtml">https://forums.audiworld.com/s4/msgs/1304045.phtml</a</li></ul>

Old school way of figuring out what size to get is start off small and keep going up in size till it
stumbles (make sure to go in no more than two jet size increments). Then jump back down one or two sizes when it does. Just because jet size X works on car Y doesn't mean it is the ideal one for you.

heh...
Bachelor's and Masters in Electrical Engineering, worked for Motorola and IBM doing stuff along those lines and now working for a software company, dealing with customers, sales, marketing, R&D, etc - where companies like Motorola and IBM are our customers.
I guess what fits the bill for what you're suggesting is when I'm working on a benchmark of our software for a customer, documenting our performance depending on OS, # of CPUs, method of using multiple CPUs, etc, etc.
Recently, our software demonstrated a 5x speedup when running on 6 CPUs. This was quite impressive and even more so when taking into account the fact that those 6 CPUs were on three different machines across a network, and the data being run was on yet a 4th machine.
When Linux machines started becoming more mainstream for my industry, we showed a 32% reduction in runtime merely moving from a Sun Solaris machine to a Linux machine, both with ~900 MHz CPUs.
So, yes, I kinda do this stuff at work too
