A/C bug rebuild project

[BIGBUG69]

Hello all
I hop it's the right forum to my questions.

I like to know what to do, so here is my situation:
I have 1500cc 70 German bug with A/C, all O.G. parts that seat 20 years.
The engine O.G. but needs to be rebuild (one piston and cylinder failed)
I'm converting the A/C to be electric compressor system, so the generator will be replaced by 75 Amp alternator with dual battery charge system.
I live in mounted hill area so need the most torque I can get from the engine.
My goal is to rebuild it to the most powerful state (considering that the case is one relief oil).
I know that it can be set to become 1600cc but what more can be done?
I will be happy to save the case original as I can and no machinery to set to much bigger cylinders than the case can hold (don’t forget the stud insert is o.g.)
So what the quality cylinder & piston set and other parts that you can offer me to get the best close to my goal?

Thanks

Converting the AC to electric will probably be a mistake. With the mechanical compressor you just have to turn the AC off when you need that bit of more power.

With electric AC the alternator is going to just keep pulling that much more HP out of the engine to charge back up the batteries.

You probably should consider going with a 74 mm or 76 mm counter weight crankshaft and have everything balanced. Just that will give you more torque to get up the hills. That plus converting to dog house cooling system will keep it from overheating.

I would stay with the compressor with the electric clutch but replace it with a new one. Sanden ,for one , makes small ac compressors that take less than 2 hp to operate.
Just my thoughts,

I think that although the mechanical compressors today are work more effective, it too much for the old engine.
The 90Amp or 75Amp alt spinning the same speed and dual charge batteries system (like camper) should do the job, with the help of the compressor controller.
Also the dc compressor with his controller is sitting at the front trunk with short pipes direct to the evaporator and the condencer is under the front car is more efficient then the old Aircon system with long hose and condencers near the engine heat.
The "side effect" is that the engine compartment stay clear and accessible, no dual carb or big compressor stand.
I've 76mm crankshaft in the new rebuild engine.
Don't froget it already work at the EV cars and Hybrid cars to.

What you thinking?

Then you need to turn it into a complete EV or Subaru engine.

If electric compressors worked you would be seeing them in modern cars.

The only reasons Hybrids have them is they run at 110ACvolts off the cars main batteries

A modern rotary or scroll compressor and an adequately sized condenser will not load a healthy VW engine down.

I didn't reinvent the wheel and background i've also. (And i'm not saying that for show-off). I realy whant to here new thinking ideas.
If i didn't see that it worked on other bugs and campers and trailers (all 12v), i will not start to build one.
The bigger the aircon system is the bigger is load on the compressor and so on...
The controller job is to balance the load that it need from the battery/alt and not to take it at once, it's Inverter.
The reason way most car companies are not using dc compressor is their calculations just like they use front wheels to drive and steer or the poor insulation on the car, mostly money.
All the things we daily use, was inveted 100 years back and the basic and Physics haven't change.

If it will work for me fine, if not i'll cry for my failure. Einstein said we learn from our experience only.

Thanks

I'm interested in seeing how well this works. I think performance will only be adequate, if that, but I also hope to be proven wrong. Good luck!

I know that like any system it got upside and downside and nothing is perfect.
I'll do my best to upload the project to the site and if it will run fine other can see and learn from my mistakes and make it better.

You may want to join a Prius forum and ask what their mileage ,power and A/C performance is when it's 90 degrees out. A hybrid is basically a eletric car with a added combination generator/power-booster gas engine. I wonder if on hot days with the need for strong acceleration ,the A/C works for crap. Stored energy in a battery has to pay the piper at some point. I could not find the amp rating on a hybrid alternator but it has to be over 75 amps. 75 amps is barely okay for a late model car.
