jalexquijano Posted February 14, 2016 Share #1 Posted February 14, 2016 (edited) Just finished installing a Vintage Air Gen II mini Kit and a Sanden Compressor 508 model. I manage to actívate the system with the rotary fan control and disabled the horizontal controls once removing the heater box and stock blower. However, i still think this system lacks blowing power as it does not blow enough cool air compared to ac systems of modern nowadays car. Is there a way i can solve this? should i consider the Honda Blower Upgrade to add this up to the vintage air gen II mini kit? Anyone?

siteunseen Posted February 15, 2016 Share #2 Posted February 15, 2016 Are you saying it doesn't work as good as a modern day system? Did you install it or pay someone? Have you fixed the other 17 problems you've complained about? I'm not trying to be a d*** but you're making it impossible not to be. There's been so much help given to you but you just ignore us. Nobody takes you serious anymore. I've typed this out of pity. 2 Link to comment Share on other sites More sharing options...
jalexquijano Posted February 15, 2016 Author Share #3 Posted February 15, 2016 (edited) I paid someone around US$800 for the installation. But the AC is not blowing enough air! Still working on the rough idle and stalling issue which only happens when the engine is hot and which could be causing fuel percolation at the float bowls of the carbs. This guy has the same problem i have in his 1973 240z and addresses the solution perfectly: https://www.youtube.com/watch?v=AW_8LggHv8A Edited February 15, 2016 by jalexquijano Link to comment Share on other sites More sharing options...
Zed Head Posted February 15, 2016 Share #4 Posted February 15, 2016 He's making progress site! The Honda blower swap is popular. The factory blower is a bit weak. Do the swap. Link to comment Share on other sites More sharing options...
djwarner Posted February 15, 2016 Share #5 Posted February 15, 2016 I would agree that the mini II fan is not as powerful as the Datsun fan you replaced, but it has never failed to cool the car reasonably well. Due to the large rear glass, the car will tend to soak up heat when parked in the sun. When this happens, it takes longer to cool the air inside the car. You haven't described how you plumbed the three outlets. I piped mine to the two circular vents on the out board sides of the dash and the center vent above the OEM ventilation controls. Turning the fan up to high will increase the flow volume but the air coming out the vents will be warmer because the heat being removed is a near constant. Turning the Thermostat control colder will give far better results than turning the fan speed up. All in all, it is what it is. If you can crank the thermostat all the way cold with the fan turned all the way up and the coils don't freeze up, you are getting the maximum cooling the system is capable of producing. If you are seeking a strong breeze blowing on your face, the mini II isn't going to cut it. Link to comment Share on other sites More sharing options...
Zed Head Posted February 15, 2016 Share #6 Posted February 15, 2016 Does the Vintage Air Gen II have its own fan? I assumed that it was just a compressor and cooling unit, and the stock Datsun fan was retained. Link to comment Share on other sites More sharing options...
djwarner Posted February 15, 2016 Share #7 Posted February 15, 2016 The Mini II has its own fan. One point I didn't mention was that the high speed power is fed through a relay rather than through the switch. If jakes' s installer eliminated the relay because he was using the OEM fan switch, he may be losing power at high speed. Link to comment Share on other sites More sharing options...
zKars Posted February 15, 2016 Share #8 Posted February 15, 2016 The hose connections and hose extension also can have an effect on the air flow. Make sure all the hoses are firmly attached at both ends and sealed, ie NO LEAKS!. Second, make sure the hoses are stretched out to the max. Assuming you're using the VA hose, the ID smooths right out when the hose is taught, but is very rough on the inside if its slack. I was tempted to run 2" aluminum pipe except at the very end ends. It's hard to get the hose nice and stretched and still stay attached. I wonder how your installed plumbed the center vent. The stock duct work behind the dash vent center outlet doesn't have a nice round place to connect a hose. I had to fab up an adapter. If your installer just sort of placed the hose behind the vent, it could be blowing cold air into the back of the dash. My system blows pretty strong. Yes, not like anything modern I own, but plenty strong to keep the car cool. Link to comment Share on other sites More sharing options...
jalexquijano Posted February 16, 2016 Author Share #9 Posted February 16, 2016 I will need to take the car back to a more specialized shop so they can verify the AC Installation! Link to comment Share on other sites More sharing options...
