DC to AC Conversion Upgrade Cost?

COPB

I was asking Gorno some questions on the Bonanza thread and thought I would move it over here. Not being a moderator, I had to just go with this route.

I am wondering about the DC to AC conversion in electric golf carts and the upgrade cost. I know that Hyperperformance makes a conversion with an 18 HP motor. I asked Gorno about the AC carts at the meet and he wrote;

I don't know which vendor supplied the hardware, but I can tell you that when one of these hi-per AC carts gets on the go-pedal there is whistling coming from under there that can be heard across a field. It's kinda spooky, but the results are incredible. For more info I would check with GarageBuilt over on the BU forum. His carts were kicking some serious ass all day!

I will never buy a gas cart.

Never.

So I am wondering; Is there other vendors of AC conversions? I was not aware of any.

The 18 HP conversion of Hyperperformance costs, about, $2,100. Now, I know that some would have sticker shock when they see this, but anyone who has put a big block in his cart will tell you that this is a very competitive price. And you would save more than a grand on a lift kit and bigger wheels and tires. Of course, you will be putting the lift kit and tires into batteries. But, it is more than a 20 dollar bill every time I fill my cart now. So,,,,,,,, there are trade offs.

You have to take into account, that this 18 HP electric would be more motor than a 30 HP big block, maybe even a 60 HP. I mean..... 81 pounds of torque :eek: and I mean INSTANT torque. So, you would be getting more than the price of your batteries back right there.

I stand with Gorno on this. I think that electric carts are the future of high performance. I know that there will always be gear heads that need to hear that engine and I admit that it is nice. I mean they know when you arrive and they know when you leave. But I find that on the golf course, I feel cheated when I have to take a gasser. The electrics are just that much nicer. And the smooth power...... it's like ridding on a steam powered tug.

Gorno,

Do you have any specs on theses carts? Are the owners forum members here? If not we need to get them over here... :D

I'm pretty sure Ron Watson is GarageBuilt at BU. I will send him a line.

COPB, is the conversion you are quoting the one from Golf Car Catalog .com?

I went over and looked and did not see any AC conversions. Do they handle the Hyperperformance motor?

Thanks Gorno. I see that they seem to be talking about the Hyperperformance product.

How long was the drag strip, 1/8 mile? Man I wish I could have been there. I just got back from a 2 week vacation.

The golf carts were measured for 1/8 mile. The track itself can accommodate 1/4 mile runs but it has a very short runout. There will not be any 7 second cars running the quarter at London Dragway, not enough track. It's a local 1/8 mile facility.

Was it a shorter or longer track than the 2nd Bonanza? I could not tell if that was an 1/8. I have an old video if someone could tell by that.
If I remember right Nate and I were in the 8 second class then, his 120volts got me by a few 10ths. :confused:

Frank,

I would say at the 2nd Bonanza the track was 1/16th mile or close to it judging your times and the videos I saw back then...

gornoman,

Thank's for the invite. I have been involved with Hiperformance Golf Car's over the past 3-years. And have become good friends with them.

They do make high end products, But you get what you pay for. We all know that on 36-48volt carts that you only can build them for speed or torque, but not both out of the same cart.

So along came the Hiperformance AC systems. Claiming to have speeds of 25 mph and 81 foot lbs of torque. And now you have a system that can do both plus a hole lot more, why shouldn't the public expect to pay more?

If you guy's have any questions or just want to hear more about AC systems, Well this looks like a good place.

Hi Ron and welcome to the forum. We are the richer for your presence. :hattip:
You bring up paying more for this conversion, but as I have posted, I do not think it is any more than a big block installation.

I have wondered why Hyperperformance advertises 25 MPH. Seems to me, with that torque, a person could put in some taller gears and still have more torque than any gasser. If a person did put in taller gears, could the speedo module be programed for accurate speed, or not?

I know of an old CC in a junk yard. I do not know the year, but it has the cartouche body. The Hyper web site, seems to me, had years for Yamaha and ezgo carts their product would fit, but I do not remember anything for CC.

COPB,

25 mph is all that a manufacturer or dealer can publicly advertise by law.
And yes gears & tires will make a difference on the topend. And the speedometer & tachometer can be set accordingly.

I had two AC carts there this past weekend.
48-volt EZ-GO & a 84-volt Club Car. And on the last run of the night, the Club Car ran 50-mph in 12 sec and I do have the time sheet. Or ya'll could just ask Nate.

Sorry I got side tracked. The AC system has alot more to offer than just speed. Unfortunately I dont care. I am just a speed junkie.

COPB, I dont know what a top speed would be for the 48-volt system.
With the right rpms,gear & tire, I would say at least 50-55. On the last run of the1\8 mile my 48-volt was set up & expecting to run 40 mph. I was unable to get it to the line.

Electrics are impressive but I just wish there was something that could be done about the range. If they ever come out with more advanced batteries electric will rule zee world!!

As far as range is concerned, an electric will more than be enough for me. I remember back in the late 60's early 70's. We would all go out snowmobiling on a Friday or Saturday night. Machines were not all that reliable then and just to get all of them running so we could take off was a chore. We would always ride until we got someplace we could stop and drink. Man, you would think you had gone so far and it would end up you had put on 12 miles. :rotflmao: No trails back then, just ones you made yourself. Then, you would ride a bike all summer and have less than 1,000 miles on it. What I am trying to say is; People tend to believe they put on more miles than they actually do.
And with this Regen braking, just go someplace that is all down hill. I could, probably, drive the cart from Minnesota to Florida. It is all down hill, just look at the map. :rotflmao:

What is the range of miles you are looking for? 60-70 mile range with a set of 8- 6volt Trojans would do the job, with speeds 12-15 mph.
