Aquamist?

Is that the name of Jackson water injection kit? Anyway, I was looking at the specs they had on their page and it said it lowers temps 69 to 100 degrees. I believe it hooks to the windshield wiper fluid container.

So, my question is to this highly knoweledgable group: would there be a performance benefit to using one these with the Hondata, larger injectors and 10psi+ boost set up?

I realize you can tune out the detonation with the Hondata, but would that aquamist system cooling propeties be useful in a high pressure set-up. Would it really sort of work as a psuedo intercooler?

I just can't remember anyone trying one with the Hondata - but if it actually offers that much lower cooling benefits it seems it could add more horsepower.

Oh, yeah, doesn't it spray through the intake? That's what I was thinking.

I mean, no one with a Hondata really should be having problems with detonation, but Hondata doesn't cool 69 to 100 degrees lower, and that is what seems interesting about using it.

I have the JR water injection (Aquamist relabeled) and I'm running an EFI PMS with the JR upgrade crank pulley. The nozzle for the kit actually taps directly into the intake manifold. I don't think it adds any big HP gains, but keeping things a little cooler should provide more protection at higher psi and higher temps. And your valves should be kept nice and steam cleaned [img]wink.gif[/img] .

As I recently mentioned, the JR WI on a 12 psi JRSC integra (>9:1CR) yielded 22 whp after all tuning was said and done.

Hey, 22 whp is fairly significant in the world of imports.

That's good news though. Cause I may die of old age before someone posts dyno numbers of their home made jrsc intercoolers.

Cotay, can you please give more info on this. I'm using it on my GSR at 10psi and stock timing and will soon be going to a hondata after christmas.

BTW: When ever I pull my plugs, they are white on the tips, I know that usually means detonation, but could it be because of the water/alcohol mix?

The last time I checked my timing it was like 14-15 degrees.

those are great results. What else was changed in conjunction with the water injection that helped yield the horsepower? It wasn't simply a result of slapping it on I'm assuming?

Also, what were the base numbers that the increase started from when you tuned? Was it well tuned to start with, or was perhaps part of the increase better tuning of the setup and the water injection?

I'm not trying to discount your results, and in fact, I'd love to see them myself. I'm at 9 psi, and have tuned with my PMS and the H20 injection. I gained 20 HP tuning, but I had a slipping belt up top that had been changed in between and the PMS was a new factor.

Maybe the difference is also that you're at 12 psi and perhaps the additional heat increase factor was hurting to begin with?

Just want to understand more and share [img]smile.gif[/img] .

cpa: How can I get the map that you are running at 9psi and the water injection?
I was planning on the PMS or Hondata, not sure yet though. What kind of power are you putting out on your car with 20 extra HP from the water injection?
How much is the PMS system with everything I need minus the injectors, and where is the best place to get it?

I'll back up a step and include the setup:

b18c w/ wiseco pistons/eagle rods
Hondata 2b w/ RC 440s
Kami header
JRSC w/ 3.8" nose pulley and endyn stepper pulley

The car had been previously dyno tuned w/ only the nose pulley and made 225 whp. a/f was 12.2-12.3 across the board. Timing was extreme as the low comp. pistons didnt seem to mind(33-35 deg TOTAL advance in boost columns).

The car was then retuned with the same setup and the stepper added. a/f was retuned and timing remained the same. Midrange power was up and about 10-15 lb/ft (177 total!) above the previous setup but peak hp was only 2-3 more (sorry, no IAT data log was available), but im sure you can guess the intake temps.

Finally on the last two runs the water injecton was hooked up after all tuning was said and done. We changed absolutely nothing. As I said 22 whp was gained, all above 6k where it began to fall. Total whp, I believe, was 256 hp SAE.

Since then the engine was resleeved to 84.5 mm, decked .020" to gain the .030" piston to head sweet spot. This also raised the comp to 10.1:1.
We are dynoing in 2 weeks at ISA in tacoma washington and should see 280-290 whp and 200 lb/ft.
Hope that helps.
