How hard is installing a window AC unit. I am highly considering buying this AC unit and installing it in my garage. It being 100+ degrees out is really killing my wanting to work on cars. Also how long does it take to actually start cooling off the room its in.
Not same but to illustrate: https://www.amazon.com/Amvent-Ductle.../dp/B0081HMXHC You'd need to size for the space obviously. |

Easy to install. I had better luck in a previous house with a ductless unit I installed in my garage. You have better choices of internal placement.
Not same but to illustrate: https://www.amazon.com/Amvent-Ductle.../dp/B0081HMXHC Note that while the unit linked to above comes pre-filled with refrigerant and uses quick-connect fittings, some come empty and require the use of a vacuum pump and then an R410 filling station after the lines are hooked up. |

The garage is about 750square feet which seems to be right between needing 14000btu and 18000btu. It has zero insulation though so I was figuring larger is probably better. The one at lowes just happens to be available today which is sort of why I was looking at it.

One of the problems with the window unit is it'll be near the floor where the ductless wall unit can be placed higher so you'll get better circulation (IMHO) i.e. cold air is heavier than hot. The fan grids tend to be variable (not sure on all). But, in general, they are higher priced. Tough call. Good luck. |

Searched and nothing definite. Symptoms of high intake temps?
I only notice this mostly in the afternoon, near 100F temps outside driving home in semi stop and go traffic. When I let off the gas pedal completely, usually AFR will shoot up to 22 for fuel cut and the car will decel like normal. Recently in the heat, when I let off there is no fuel cut. Runs rich (10-12 AFR), sputters.. RPMs slowly fall. If I release the clutch it still runs rich and the idle is at around 2k RPM. IAT is right behind the radiator :cry: A lot of examples I come across is with megasquirt, hot iat but running lean... Just want to be sure before I start investigating on extending the wiring down towards the intercooler piping down below. Get it drilled/welded or whatever and take off the powder coat on the existing piping... Or use the IAT piece found on BEGi's site. |
That window unit will improve your life. Do it. Low country has special requirements for managing Summer.

I bought the biggest window unit that Lowes had. I should be hooking it up tonight or tomorrow once I get some one to help me. Now I am debating installing some insulation. Is it worth doing the sides and not the roof? I have zero desire to get into the rafters to attempt to put insulation up there.

Also, if there is any possible way for you to include a radiant barrier under the roof, you will be absolutely amazed at the temp differential. http://www.homedepot.com/p/Reach-Bar...Q&gclsrc=aw.ds |
I use ductless minisplits because my "house" is a 140 year old church, and it was the easiest way to retrofit AC. I just installed a second one yesterday.
Do it, but don't use the one linked. You want to find something with a high SEER. 110 units are available now with SEER numbers above 20, which is ultra efficient. 13 is below the energy star threshold. My electricity bill does not significantly change when running it 24/7 when using AC, but it increases a bit when using the heat pump. Have 2 extra sets of hands when you install. Find an AC guy that is willing to work on a unit he didn't install to vacuum out the refrigerant lines before you release the Freon. It shouldn't cost you more than ~$40 |

So far, still looking for a solution...

Coolant is rock solid at 200F~ 12:00 on gauge. |

NO, that would be a waste of time if you aren't doing the roof. You could do the roof alone and get a decent return on the effort, but not the walls alone.

Tell me more, tell me more. Our upper floor ceilings are insulated in the attic but the attic gets hottt in the summer; there's no insulation on the actual roof. Would I just nail this onto my rafters to create a radiant barrier beneath the roof?

So today i decided to check out that exhaust leak..
A weld in the exhaust broke in the...... Are you ready? The BEGI DOWNPIPE. There is a joint where the pipe going down meets with the 2nd pipe that goes under the car. Right before the bend there appears to be press fit welded joint and it cracked all the way around. |

How old is the downpipe? I mean I wouldn't exactly be mad at BEGI. Sometimes welds fail, there is not a vendor out there for miatas that I have not seen have zero issues ever with cracking welds. I have seen plenty of cracked turbo parts frm FM, Artech, Begi, Absurdflow over the years. It sucks when it happens, but you just take it to an exhaust shop and have them fix it them move on with your life. No miata turbo parts out there are sold at a price point to have perfect welds 100% of the time. You get enough out there with enough miles driven on them and eventually a few will have issues.
