IC Sprayer results and question
I hooked my washer motor up to a mister and set it up to spray my (stock) intercooler when I am under boost. So far I'm getting good results (150 F max, faster cooldown after boost) but the temps rise after the boost. So I'm wondering if there is a way to have the system lag a bit. How can I get the circuit to stay on for a few seconds after the switch goes open ? Would a capacitor work ?

Thanks, I'll look into it. I also realized I can put a check valve in front of the pressure switch and a needle valve after that. Then I can control the bleed down of pressure seen by the pressure switch.

Ok, I did the pressure thing. I had to add a liquid soap bottle as a pressure chamber (probably get an rx7 one later). The needle valve work wasn't the right range (not restrictive enough), so I put a .5 gph fogger nozzle on the end. Intake is now briefly 125 on full boost, and drops within a few seconds. Next I'll be improving the mister. BTW, how many of you didn't know there is a big HOLE in your IC duct that points at the battery ? Just sealed mine with foil tape and I'm sure that's helping, too.

No it's not Turbo'd
Heat Kills the battery and that hole is menat to blow out any stagnant hot air that's in the battery tray...
So expect to go through more batteries than before...

I was just saying... there's a reason for most things on the 7.... most are not immediately apparent...
Except for that intercooler paperwight, I think you can yank that, no problem....

Update, changed out the POS metal mister for two DIG foggers. Much better mist. Checked the flow, it will take a LONG time to empty the tank. Now I'm going to set the pressure switch to come on earlier, try to get ahead of the curve. The secondary turbo adds some serious heat ! Also did the fan mod. Got rid of the heat soak. Otherwise 140 F intake temps on starting the car !

The LaBreck/Unobtanium bushings do not come with pillow *****, if that's what you're asking.

I'm looking at doing the max cooper pillow ball bushing replacement (http://www.maxcooper.com/rx7/how-to/...lls/index.html ). I know there is a tsb for bushings for pre 5/92 (mine is 4/92). I'm wondering if the tsb is included in the 6 pillow ball bushings.
