**Fresh update 16 Feb 2011**
OK, so in the holidays I bit the bullet and installed the TD05-20G with 1.2BAR actuator that I had bought while I was away for work.
Went to my mates house and plugged the laptop in, plugged the wideband in, loaded the updated ECU files and started road tuning
Did various load and gear pulls on the highway to Charters Towers (110km/h zone) and came up with some fairly solid/safe AFR's between the 11.5-11.8 zone with a fair bit of consistency with some good timing with a boost pressure of between 21-22psi (yes im crazy) which holds fairly solid. We had tried for 23-24psi but from there it was pinging and that seemed the limit for the fuel/timing as well until we can look into the fuel a bit more. Hence we backed it off to 21-22psi which made it safer that way
(Especially on a stock bottom end 93T) LOL
On the highway the car is an animal on acceleration with the 20G and it hits loose licence zone very quickly
I just hope it can translate to the strip as well, because there is a big difference between fast shifts at the strip (from standstill) and gassing it from different gears on the highway...
Moving on to the next project:
Water/meth KitI had purchased this coolingmist.com kit way back in late 08 to add some more cooling power for the car and combat the hotter weather up here and I just havn't got around to fitting it
Its a shurflo 150psi pump with a 1 US Gallon tank (~3.785L for the Metric conversion) controlled by a boost pressure switch and I cant for the life of me remember the nozzle size! Im sure I asked for the 400HP kit/nozzle.
Since there is so much shit in my engine bay and the front bar, I couldnt find any real room for the kit in there, so my attention turned to the boot area for some inspiration.
I decided to fit it in the nice gap in the boot behind the wheel arch and made it as flush mount as possible. I made up some plyboard backing plates and spaces to mount the tank on that with the pump mounted behind it (which is the only part really sticking out now). The kit really didnt come with long enough 250psi bursting strength nylon hose for the water to travel to the front, so I got a nice length from the hose supplies as well as a QD T piece and another QD straight joiner for future nozzle additions.
I have run the wiring and the hose through the side carpet near the door trims to the engine bay for the boost switch and the ignition source and it is nice and out of the way. The boot carpet is hiding most of the wiring and the hose, apart from the obvious, and wiring run from the battery which holds the relay for the system. The nozzle is mounted about 6 inches before the throttle body for good evaporation and cooling effect and it is said that this system can even clean the pistons of the years of buildup, (there is even some pictures/writeup about it on evooz if you ever get over there for a look).
I have the boost pressure switch set to come on at only 6psi, but factory setting says it was supposed to be at 10psi, adjustable up to 25psi but Ill leave it for a while and see how it goes. When I got home from my mates place where we did the wiring install, the intake manifold wasnt as hot as it usually is! Id say it was only lukewarm at best and usually you cant even rest your hand on it as GSR/Evo owners should well know
It should be cooler once the 50/50 water/meth mix is in.
To test the before and after results I have some K-type thermocouples coming in 4,3 and 2m lengths to test 3 different locations in the intercooler pipes, which will be 1 after the turbo, 1 after the cooler and 1 before the TB. Ill be testing this at the drags or street without it on, then with the coolingmist system being on. All in all it should provide a bit more of a buffer in this hot weather
Next on the cards will be the giant intercooler in the garage
more on that when/IF I actually fit it.
