DO NOT waste time with anything other than Aquamist. We've all been here before, but ponying up the extra $500 for the quality system and failsafes is worth it.
Also, running W/M for just "cooling" is completely stupid. Basically you end up spending a pile of money for nothing, and in the end want more power, and then once again you have a sub-par system with low quality nozzles and junk failsafes (if any).
FWIW, I've been running a really aggressive high timing (20 degrees at high RPM, and ~30psi) file for like a year and a half and my car has never seen 100+ octane during that time. I rely on Aquamist for the fueling/knock resistance, and it's never let me down. And my car sees 20k+ miles a year..

I have a question for the big turbo gents, I recently broke a piston, and had to get some new ones. At the time I nor the mechanic knew the exact reason. After doing some hunting I found that it's more than likely the wastegate not opening, thus leading to at least 32lbs being created. Do the internals, ringlands/pistons hold that type of psi and I just had a bad piston, or it that type of psi too much for the ringlands/pistons? I am going to fix the issue, but I was just curious.

I already put new OEM pistons back in, and by me, I mean the mechanic. Was that a mistake? I was under the impression the pistons were pretty stout and that the rods were the weak point. Even though I had a piston break. However I got IE rods put in as I got them at a good price at the time of install.
Not a huge update on my front, but I bought a QTP low profile exhaust cutout. The switch is mounted, but I still haven't really figured out where to put the actual cutout, nor have I looked. I almost pulled the trigger on the raceland one since it fits so nice, but I didn't want to deal with it leaking a month from now or immediately.
I'm hoping I can fit it above my "UB-type" brace and have enough room for it not to be hitting everything. I'll get under there and cut/cut/cut/hack/weld tomorrow most likely!

That's with it being removed and installed multiple times on multiple engines with a wife who might not be the best at using a clutch. It only slipped when cold too. I want to get dyno tuned though so I didn't want to risk it.
i say put it as close to the turbo as your willing to deal with. i think fireballs was right behind his subframe
