Since you didn’t mention it, I thought I’d ask. Are you upgrading the alternator related wiring when upgrading your alternator?
You need to go back to factory seats or retro seats for harry. Those racing seats are shit.
I'm not even close to as expert as you, but is it okay for the oil lines to rub up against the condenser fan? It seems like it could rub through over time.
Nice work. ✌️✌️✌️
Here in UK an onboard log fire is more of a priority.
I can't help being captain obvious here. The fact that the A/C is not pulley driven but electrical makes no difference to how much engine power it will eat up. Kilowatts is kilowatts. When you turn on the A/C your new beefier alternator will need to generate as much power to run the A/C would've taken when driven by the crank directly.
Why don't you use a heat gun for heat shrink tubing?
Hi Jeff – I have a 1985 911 with factory AC that barely cools. It has the same small side vents, but also has a center dash vent which works well for fresh air. In any case I'm very interested in seeing how well the electric retro-fit AC system works. Keep up the good work and excellent videos!
This couldn't have come at a better time. My old man just got the same kit for he's g series and no one wanted to touch it in Sydney without charging an arm and a leg to install it. We just got the 175a alternator installed so this walkthrough will come in handy
Oops…………at around 19:30 you mis-state the basic air conditioning cycle. The whole process can be done with ordinary air (that's how most systems work in airliners) but it is much more efficient and compact for an A/C system to use some sort of special gas which can change state from a liquid to a gas and back again at reasonable temperatures and pressures. "Freon" R-12 is the familiar stuff from days past, but these days cars usually use 134-A or the newer R1234YF refrigerant.
The compressor discharges hot, high-pressure gas. This gas then goes to the condenser (not the evaporator as you say) where the hot gas is cooled and turned into a high pressure liquid. Since the hot gas not only gives off it's heat, it changes state to a liquid as well; therefore, the amount of heat rejected to the outside air via the condenser is even more dramatic. From there it goes to the expansion valve near the evaporator (inside a box under the dash) where the high pressure liquid is expanded and converted into a lower pressure gas. Any gas cools as it expands, but by also changing state from a liquid to a gas, the resulting heat absorption is more dramatic. As this cool gas travels through coils the box, a fan blows cool air into the car. The cool, low-pressure gas is returned to the compressor where it is again converted to a hot, high-pressure gas thus completing the A/C cycle.
I noticed one of the condensers was touching the wing/bumper flange at the AC line connector, can the condenser be moved inboard or put some edge protection on wing return flange
Happy holidays to you and Mrs Jeff. Hope you are all well. Stay safe
hi Jeff great work as usual. 🙂
but should you heatschrink the entire fuse?
how do you see if it is blown?
