lookforjoe Posted December 10, 2008 Author Report Share Posted December 10, 2008 50-24psi - 26psi. you're sure it will atomize?Where's the subtraction? The line pressure is constant (assuming the pump is functioning as intended), why would you deduct the boost pressure from that? The nozzle will inject a specific flow volume based on the psi pushing fluid through it, the boost pressure is not related in way that I can see.

lookforjoe Posted December 10, 2008 Author Report Share Posted December 10, 2008 Looking good Hussein, would be interesting to see a video of a test spray out of the water nozzle. Curious to see how it atomizes at various pump pressures.I'll see what I can do when I get to that point. Link to comment Share on other sites More sharing options...
Che'_Moderator Posted December 10, 2008 Report Share Posted December 10, 2008 Where's the subtraction? The line pressure is constant (assuming the pump is functioning as intended), why would you deduct the boost pressure from that?Cereal?Its the pressure differential. Think of the fluid dynamics like this. Your piss upstream in a river with a 3 psi current with a force of .5psi. Which way does the piss go? I'll give you a hint. Its not up streamnot sure how it works.. never really looked into it muchthink you have to run a pressure line post turbo then an inlet line pre turbo.only guy ive seen with it had it on a vortech S trim blower carI'll pass on hosing my turbo down with alcohol.

JCviggen Posted December 10, 2008 Report Share Posted December 10, 2008 not sure how it works.. never really looked into it muchthink you have to run a pressure line post turbo then an inlet line pre turbo.only guy ive seen with it had it on a vortech S trim blower carI bet the compressor blades look great after a couple of runs... Especially because there's no way to get the droplets very small with low pressure like that. Link to comment Share on other sites More sharing options...

Its not up streamAdditionally, think of a fuel pressure regulator which uses a diaphragm to increase and lower line pressure linearly with manifold pressure/vacuum... To maintain a constant effective pressure. Link to comment Share on other sites More sharing options...

Its not up streamOK, thanks for the clarification, but aren't we injecting into the stream flow (just prior to the throttle body), not against it? I certainly wasn't planning spraying backwards up the inlet pipe... I'll pass on hosing my turbo down with alcohol. Link to comment Share on other sites More sharing options...

Well not unless his phase two plans include direct exhaust injection Link to comment Share on other sites More sharing options...

Well not unless his phase two plans include direct exhaust injectionOK, so that comment was intended for him? Wasn't clear. I understand that the boost pressure will effect the spray, but it's not static pressure, correct? So if you're spraying into the pressure stream, what adverse impact would that have on the water injection pressure? Link to comment Share on other sites More sharing options...
SRTthis Posted December 10, 2008 Report Share Posted December 10, 2008 i didnt say it was a great option... i like the idea cuz there is less that can go wrong... i hate wires. if i can find a way to do the same thing as well with out wiring something up. id rather go that route. but since there is little on no info out on the mr freeze kit i figured id ask Link to comment Share on other sites More sharing options...

I understand that the boost pressure will effect the spray, but it's not static pressure, correct? So if you're spraying into the pressure stream, what adverse impact would that have on the water injection pressure?It's static enough... I would scale the voltage on your pump to get line pressure equal to your eventual effective pressure (50 psi line vs 20 psi intake charge-- 30 psi?) and test to see the spray pattern and atomization before you install everything. Or else bump up your pump pressure to compensate, as you said it was adjustable? Link to comment Share on other sites More sharing options...

Yes, the pump pressure is adjustable, just like the Hobbs switches, there is a lockdown screw for raising/lowering pressure. Link to comment Share on other sites More sharing options...
TorqueSteer Posted December 10, 2008 Report Share Posted December 10, 2008 After you are all done with the kit, do you mind listing your cost for the kit, im curious to see how much cheaper it is than buying a whole kit. Link to comment Share on other sites More sharing options...
