Just looked at my Coolingmist components today and wasn't impressed! They sent me a defective nozzle. When i called them the guy was insulting and didn't believe me.

After sending him a picture of the defective part I didn't receive an apology for their mishap or any of the like.

His response was

"wow I will send you a new one"

 

It's hard for me to tell from the picture, whats defective about it?

 

There is only threads on 50% of the nozzle! The other 50% is threadless! lol so once you screw it into the manifold you cannot put a fitting on it!

 

Figured out my oil feed dilemma! Didn't have to purchase any fittings just moved things around and it worked




Once the feed was in place I was able to clock the turbo and install everything else!



Also got a chance to work on my dedicated methanol injection manifold. I went ahead drilling and tapping all the coolant ports on the manifold and the IACV. Also drilled and tapped two vacuum ports that will not be needed at the moment but I can easily install a quick connect fitting if needed in the future. Should look clean Everything was tapped with 1/8NPT and will be plugged with blue anodized plugs

Nice work. How did you get out the nipples on the IM? Did you just drill them out? Or use heat and pull them out, just wondered.

Good idea.

 

I tried heating up the area around the nipples with a propane torch I had at home but they didnt budge. I just cut them off as close as I could and used an 11/32 drillbit to chase the existing hole. It worked out well and guided the bit centered on all the holes. It got rid of all the steel nipples and my tap was cutting through aluminum on all the holes so it worked out well!

The IACV absolutely doesn't need the coolant to function. When I took it off you could see exactly how it works. The coolant lines literally just heat the iacv and do not pass through anything electronic whatsoever.

 

Right, but w/o coolant, you will have to tune your car more exact to function in changing temps. I know where I live during the spring/fall it can be in the 80's during the day and fall into the 50's at night.

Not at all. I'll take better pictures of the inside of the IACV when I get home. Basically the IACV consists of two chambers. One which leads into the Intake and one which brings in air from the throttle body. It has a servo motor which connects these two passages letting air into the intake when needed. The coolant portion is literally just a pocket which serves to make sure the servo doesnt freeze up in cold conditions. Much like how a carburetor can freeze on a snowmobile in the winter.

Having the iacv as hot as the engine serves no purpose to its function of controlling idle apart from preventing the servo from freezing and not opening.

The ecu opens or closes this servo based on engine idle or cold idle settings. Theres no reference or sensors for coolant on the iacv so it will not affect its operation.

 

Interesting. I've just assumed, perhaps poorly based on what I've been told in the past. I've had mine apart last year, but didn't think twice about it when I was cleaning it.
