Our test went well. Check out this video from the inlet. This was injecting straight water through a 7GPH nozzle (rated at 150 psi), but with a 250 psi pump. Turbo is a HX-35. Figured I'd share this video because I thought it was pretty cool. I'm going to start a thread tomorrow with the details of our test.
Yeah, it was an older model dyno and it's a bit finicky. And due to the way that he had to actuate the throttle to prevent it from stalling after a pull, it did surge a little bit. The water spiraling out toward the end is the anti-surge compressor cover doing it's job.this is kinda ground breaking.. for me at least.
was that a little compressor surge??
Yeah, I see now. After doing this test, I'll much less worried about a few small droplets. We were using a check valve, but it was like 4 inches away, so we kind of expected a small amount of drain off.See why I wasn't worried about the tiny little spurts of fluid coming out of the nozzle when it shut off! Did that setup have a check valve?
That's some killer footage! Why did it look like the pipe was being saturated with fluid behind the nozzle before it came on? Just residual from previous runs?
I thought you were going to be testing on your compound setup? Throw that puppy on an AWD dyno and get some video... or more importantly some good temp,hp, and spool up data!
that was a very cool video. between seeing these test results and finally seeing the compound turbo monster up and running it will be like having Christmas and a birthday one after the other.
That was due to surge. I wouldn't expect the same effect during normal opperation. It's also worth noting that we were spraying a large volume of pure water in that video. Other fluids like methanol and washer fluid atomized better and flashed off much quicker, so it left little residue in the pipe and not nearly the amount coming back out when it surged. So, compressor damage is definitely going to be dependant on the nozzle location, fluid type, and the volume and pressure that it's being injected. But that's an entirely different test. We'll see if my little B16G picks up any damage after this year.I am very surprised to see the amount of water the turbo chucked back out. its your opinion then that this would not cause damage to the blades over time? it looked rather violent.
We thought it was a pretty sweet video too. It was something that was hadn't seen before, so we figured we would try our best to get a good video of it.PS. very cool to see the water come spiraling back out, and even cooler to see the camera nearly get sucked into the turbo.
edit: i wonder if that would count as a flow restriction and throw the numbers off.
aero_sallee: thanks for clearing that up. I was thinking of it like amperage drop in a parallel circuit with a single dc power source... i guess my confusion in my own example was that voltage would be the psi and amperage the total GPH flow. which would make sense in both the analogy and in the plumbing i think.
sorry for crowding the thread up with remedial questions.

I dont know this is a reason for people to worry less about possible damage, i think we would need to see if their was no detectable wear over quite a few of these pulls wouldn't we? Not trying to be a nay-sayer, i want to see this work, but i worry that we have jumped to a conclusion based on what we wanted this test to show.

Thanks! I have high hopes for it. I'm using your 250psi pump, BTW.Neat test you got goign on here.
