Yes I know how it works. I just do not agree 100% with the post. No matter what Pat does he has a small intercooler. While the water spray may bring down the air temps. It will not get more air into the engine. The flow size of the core will not change. Also if the water spray is not a very fine mist you will not get much in the way of gains. All you are doing is changing the point of detonation by slowing down the burn. It may stop detonation but it will also cost power, because water does not burn. This is why the early systems did not work well. The very high pressure systems spray a very fine mist into the intercooler tubing. Another very good way to cool the intake change is to use extra injectors. The very fine high pressure spray of the MPI extra injector setup works as good as any water injection kits out there. The thing this way is you are not only cooling down the intake charge you are also adding fuel.
the BEST way for him to reduce detonation is to INSTALL THE FRIGGEN NEW TURBO KIT WITH MUCH MORE EFFICIENT INTERCOOLER AND TURBO THAT HE HAS LYING AROUND
that will solve most of his problems.
sorry, but I just couldn't pass up the chance to rib him about it... again....

I no longer have the J&S, and I can't install the new setup yet because I don't have all the parts yet. Trust me, I really want to get that thing in there. There are also some local import folks taking noise about the Protege's, I want to lay the smack down.
Well tonight it seems my car got slower, or JDM Sam's car got faster. On my old tune, we were even. It also didn't help that he started in 3rd gear, and I started in 4th...but I still hung with him anyhow. We did discover something else, or rather I was actually made to notice that my boost needle kept spiking up and down, and was not steady. Since Sam has experience setting the duty cycle on other boost controllers. So we put a decline trend on the duty cycle towards where my topend is, and I notice the boost holds steadier now. It "feels" slower due to it not spiking up and down giving me that extra push, but that was also counter productive to my engine reving smoothly. Got some ping I guess due to the boost holding steadier now. Making some small adjustments to my map. Here are the pictures of my wastgate map before and after below:

Tonight when I left work, I found another vac/boost leak. When I had the MPI in I was trying everything to get my car to run like I wanted it to (when the problem was totally something else). I had hooked the vac lines to my stock fuel pressure regulator to a boost signal. I later reverted it back to the stock setting, but had to add in a 3-way vaccum T there, with a vaccum cap on the 3rd leg of the T. Well, I went out and started my car up, and remembered that I had thought about hunting for more vaccum leaks earlier, so I popped the hood and put my ear by the intake manifold. Low and behold, that familiar sucking sound that I still hadn't been able to locate. I wiggled a vac line around just for grins, and low and behold, the pitch of the sucking sound changed. (hmm) I did it again, and the same thing, so I gave a closer look. Low and behold, there was a hole in the plastic vaccum T! Looks like the plastic had been melted by hot air. (eek2) I killed the engine, and pulled out my Defi Boost Gauge box from my trusty garage in the trunk (where I had about 2 ft of extra vac line), and replaced the line. Started the car back up, and where my vac reading used to read just at 20, it now read slightly below 20 now. I put my wastegate map back to where it was before. My car pulls again!
Tonight I was pulling my car into the garage, and my idle gets all irratic...like upwards of 2500 RPM's and s***. I get a knot in my stomach. 
I am of course logged into work, working on a change request, so I couldn't deal with it right way. When I did go back to the garage, I pulled off the MP3 cover and looked around. The presure of starting the car had popped off the PCV valve line from the manifold! I will be sourcing some clamps tomorrow. As a matter of fact, I will be looking for clamps for ALL my lines. I am even considering starting a thread about clamping all your vac lines for those of use who boosted a N/A Protege.
