This is a very cool conversion. Nice quality parts, Nice mechanical skills.
FAST from 0 to 30, Quick to 60, Faster than gas to 100 ..... Electric is all about the torque.
More wind load at higher speed will drain the energy much faster than rolling along at 35mph.
You can have range and speed, just not on the same fillup, like a gas car with a 2gal gas tank that takes 5hrs to fill.
You can go 100mph on 2gal of fuel, but you won't get 30mpg.
As the battery pack starts to drain down,the inverter can adapt to the lowering votlage from the battery pack by automatically boosting it back up to full voltage so still have full power.
I'll bet the acceleration is a BEAST!!
It's cool that you did the conversion, but I love the sound of a Porsche engine...
Never saw 2 motors stacked like that b4
0-60 times are still relevant .... really helps on highway ramps
This set up makes the car go faster no matter torque (twisting power) or Horse power (units of measurement). When quantitative analysis is applied here then in theory it produces 400 horse power compared to the old boxer Engine @ 185 brake horse power.
Charging connector right next to the washer fluid? Bright idea ;)
What's the 0-60?!! That's the useful bit of info when people ask how fast it is; and how far does it go?
Lets say as this :
Heavy truck 3500 rpm, 1000 hp, 3000 Nm, top speed 120km/h
Car 10 000 rpm, 1000 hp, 1000 Nm, top speed 420km/h
So if you need somthing to pull you need low rpm with high Nm or if you want speed you need high RPM with lower Nm (both car and truck have same HP 1000 )
You must first know what you need for then find balance between HP and RPM.
most important question is ,whats the range?,,how far can it go on a charge??
very cool
COOL CAR !
i find the driving experience should be and always be hearing the engine, using the the gearbox and the way the power is delivered to the wheels. stuff like that give the car its personality. the electric engine sound like they will be ok for the people who just want to get from A to B on short distance trips but for people who just want to enjoy the car.... its going to take alot of convicing for most people to make the change when more electronic cars come out
depends on your application, but rpms are largely irrelevant so long as you can gear it down to whatever speed you want. it only comes down to the toque required to do the work, and the power required to produce that torque at the desired rpms. So to answer you question simply... its all about power. power is work done per unit time, the more work you do, the more(or rather faster) things can be moved.
Yessss... and the limits are running away from it's followers.
Excellent. Upgrade the electric Porsche with solar cells not only charging the battery, but also running the car longer by sunlight.
Porque no enseñas las baterias cabezon
I think you need to look up the relation between power, rpms and torque. if you have two 1000hp motors like the ones you're comparing, then they can both produce the exact same torque if geared to the same rpm output via a gearbox (ignoring losses in that gearbox). whats more important is the size and weight of the motor per kw produced. small high rpm motors can produce more power per kg/L, and thus are more usable in a sports car.
What type/brand of motor was used? I have a 1981 Datsun 280ZX and those would fit in my engine bay with room to spare
What kind of motor is this how can I find one
How much weight did it gain?
what is that blue car in the background at 0.06???
So what is more important hp or rmps... I see 1.5 at 2500 and 6ph at 3500 rpm
People ask questions because they are curious (and interested)
But why do people still ask how fast a car or another will go if most countries have
How much cost conversion?
I prefer the air cooled rasp of the original. Danke schön.
People you do not ask the right questions, how much is the engine? Conversion possibilities? Miles per full charge ? Batteries warranty? Is a 200 hp available ?
What's the range? Huh
2.5h to full battery from 9 years and 400hp.....man
Because a speed limit doesn't mean you can't go faster, it means you shouldn't! :D
why two motors?
Does anyone know what the streamlined blue car in the background (from 0:06 to 0:08) might be? A Google search has yielded no results so far. Thanks.

Amiyah Glass, this is so funny! I thought that you were making on of those silly jokes that web surfers are so fond of. But no. It is (or was) actually called the ETV! Thanks for the info. I found out it was correct by looking up what show it was (Tampa EV show 2012) and that lead me to more images of the blue car being off-loaded from a truck to the exposition hall, etc. Thanks!
170 mph electric porsche huh. I would like to see that.
Simply you put the car in a test bench and you measure the torque, the hp and the speed all in one shot.
People are so misled by how fast a car is. Horsepower means absolutely nothing. It just describes how well the torque is maintained as RPM increases. So people say, "Oh that diesel only has 500 horsepower, my ubiquitous supercar is faster" well, no. The supercar revs super high, and maintains it's torque at high RPM, so it has a high horsepower number. However, the diesel may only rev to about 4000 or 5000, but it has a stupid amount of torque. The low redline means that 500 horsepower at 4000 RPM translates into a much more powerful engine.
That is why electric cars in particular, are thought of as slow because they only have 200 horsepower. But, as soon as the motor gets off of the starter solenoid, if it is brushless, or from absolute 0 rpm with a brushed motor, you have more torque than just about any clutch, transmission, or tire can handle.
I have an addition to make, my statement applies to diesel and electric engines and motors, however, with gasoline engines, IF your engine revs REALLY high, such as a sport motorcycle engine or formula 1 engines, your gearing can be ridiculously short, so you can get a great mechanical advantage. However, that mechanical advantage is to make up for the lack of torque. Torque is a force, horsepower is just a descriptor, so in the end, the amount of torque at the wheels is what moves you.
Dude. HP or watts (different units that measure power) is a product of torque and RPM. An internal combustion engine can develop its max HP at one speed only which is the maximum allowed RPM for that engine. If your 500 HP engine can run at a maximum 5000 RPM, it means that at 2500 rpm it will develop only 250 HP. As the engine's RPM increases, so the HP will increase until it reaches 500 HP. An electric motor is much more flexible because it can use all the available power at almost any RPM. If the RPM is increased, the torque will decrease to match the power delivered to it. If you feed an electric motor with 500 HP of electricity, it will use it all regardless of its speed. And that's why a 500 HP electric motor will perform better than a 500 HP gas or diesel engine. Got it ? It's physics. FYI at low RPM, no internal combustion engine can match the torque of an electric motor, that's why locomotives use electric transmission instead of a crankshaft and gearbox to get the tonnage moving. Btw 500 HP at 4000 rpm means 500 HP, not more.
What you said is completely wrong. So many wannabe mechanical engineer don't understand hp is a direct translation of power 1 hp = 745.7watts so what it means is this is a 300KW motor. Being 300KW is its maximum power delivery. I'd understand if you said my car has 300ft/lb of torque its faster than your 250ft/lb of torque car as the lower torque car may rev faster and be quicker, but hp is a combination of rev's and torque which means directly how fast the car can accelerate, the only additional factors then is weight, drag friction ect. I'd agree in part if compared to a turbo engine a 200hp electric will probably beat a 250hp turbo as the turbo's power delivery is far from linear but compared to a naturally aspirated car the figures are pretty comparable in acceleration.
watch my electric conversion
I wonder if he has the same problems that the tesla has.. From the Battery to the motor, the Tesla was designed very well, yet take it around a track and see how it holds up. The batteries curve with use, and going on a track really emphasizes this. Battery tech needs to go through a few more leaps and then it will be compatible to internal combustion. As for now there are some obstacles to overcome : /
Simple, because some of us frequently drive at more than 100mph in highways,
Near me in Portugal.
Combine this with a graphene super capacitor which charges in seconds
what motors are they?
i think they are duble warp 9 motors
Warp motors are DC motors.
that's a lot of horsies but I'm just not ready for electric cars and I'm wondering how that's gonna affect my electric bill? my elecltric bill for a month was an extra 100 with one tiny air conditioner! I know I know it depends on my kwh usage but still !
Electricity cost for powering a vehicle is 1/10th the cost of petrol
I think typical car uses 20kW of power if you drive "economically". One hour of 20kW driving is 20kWh. How much 1kWh cost in the US?
***** America's national average is $.12 per kw/h. That means that an hour or driving at 20 kw/h would be $2.40, but that doesn't sound right to me.
The Nissan Leaf can do 500 Km for $5, the average speed is 80 or 90 km/ph, that means the the Leaf uses about 80-90 cents per hour.
Boris Tyson I saw Nissan Leaf data. It has 24kW/h battery. Full charging cost $2,88 (at $0.12/kWh). In ideal conditions, on highway at 60km/h range is 222km, so it uses 11kWh/60km or 11kWh/hour. So Leaf can do 500km for $5, but this is for ideal conditions and not 80-90km/h. There are test results at Wikipedia: en.wikipedia.org/wiki/Nissan_Leaf However I'm pretty impressed. Maybe it's time to put some solar panels on roof and harvest "free" energy?
This is why im building one, my electric bill is included in my rent to i pay 625 for a 2 story house each month, so this to me sounds like an awesome idea. Wife is already buying me a shell for our one year anniversary.
No. hp, or kw, is a measurement unit. tell me which has greater volume, a liter of water or a liter of oil? its the same with power. a 400hp motor puts out the same (peak) power as a 400ph engine. The difference that you've missed is that the motor will put out that power at much lower rpms, and over a broader range of rpms than the engine, which is why it so easily outperforms it.
He looked uncertain about answering her questions.
I would too Joe Joe. How fast is it? Do you mean how fast does it accelerate or top speed?
Since its an electric, and electric motors are capable of developing their max torque at essentially zero RPM, 0-60 times are almost always better than a comparable ICE.
They've solved that too. There's now an electric aircraft.
And heavier no doubt!

yeah you read good ``1kw input 4kw output`` and i am not joking and dont tell me about physics laws ther are wrong.
I agree, to a degree. NASA has been using Hydrogen/Oxygen fuel cells to produce electricity for nearly 50 years. Hydrogen however, has its own problems because its almost never found in nature in pure form. It almost always needs to be separated from some molecule which usually takes a lot of energy.
Chuck O There is abundant carbon-free hydrogen potential here in Canada with our large hydropower surplus. Problem is demand, storage/pumping and shipping infrastructure more than availability. I'd be willing to go hydrogen if it were available and some bugs were worked out.
I can't wait to see some of the conversions from wrecked performance model s Teslas with 416 hp and 443 fl.lb. torque in a much lighter frame and lighter (less large) battery. Something like that will go like scat! ;)
There was that Stretched VW van, can't remember seeing how it finished though. But there are lots of problems with doing that unfortunately... you'd need a custom fabricated frame which could support the battery from underneath... too costly
MuzzaHukka
Do it when cops aren't looking?
The electric Porsche was nice I guess but how many are like me that wants to see and find out what I the blue car in the back ground Holly crap no that looked cool
Newb questions..."how does it charge"?..."how fast does it go"?🤣
Within the next year or two everything is going to be changed. Research on new Battery tech just in the last 6 months to a year. ;)
riiiight.....we follow speed limits :)
Da, da! Muuuuuuuul....
naww a trip to the pump when gas is about $6 per gallon is all it would take
400 hp electric motor is not same as 400 hp petrol or diesel engine..
You can solve those problems by using hydrogen fuel cells to provide electricity instead of using batteries.
because people like to think they're badasses who could be involved in a high speed chase at any moment.
Man ask ``So what is more important hp or rmps`` i say simple thing.
The gearbox is you can say is another part of story.
Fuel consumptions per output power per Kw that is a looong story.
Pull out from car its petrol engine of 150 Kw and put Electric motor of 150 Kw you will think you driving F1 car. Faster more powerful..... and you can drive at full power output at all time with electric motor but with a petrol it will be big bang BUUUM after that you will need a prist or new car.
people who buy these cars who dont always go the speed limit haha
Yeah, I know I'm stupid :D
Judging on the "smart" smears on the roadside, I'll keep being dumb :D and perhaps live longer.
LOL...limited to 160 to 170 mph...How ya like me now?
Electric cars simply haven't caught on because the car companies aren't making them available. I've seen one Chevy volt on the highway. I've yet to see a Chevy volt, Nissan leaf, or mitsubishi Imiev for sale at a dealer. They aren't selling because the majority of people will not buy a car without driving it or at least seeing it in person. In the end the car companies will stop make EVs and say no one bought them. Even though they were never available to test drive at dealerships.
Could go faster if they had the gearing.
Battery, 40 amp electric motor, alt. Learn to wire this, you will never need to charge any other way
1kw input 4kw output? yeah, because fuck reality....
U are right i have the same problem with the EV apocalypse, but when batteries technology get more development in the future and sold in masses EVs will be cheaper, lighter, maintenance free and faster you and me will be forced to convert into EVs (Unfortunately).
For the same reason we pull into bikini car wash's and pay college girls to pretend to wash our cars.....
You can use inplix instructions to build it yourself guys.
Its pointless on a full course track, other than drag racing, they 'sag' after a hard lap and continue to decline in speed AND torque just as a simple R/C car does. As impressive as they can be in the 1/4 mile, you wont see electric on an F1, Le Mans, or NASCAR for that matter anytime soo. They can be fast but it kills any endurance. Our current tech allows for the slow but steady method, and that alone... at least for now.
I dont know if this counts as 'any time soon' but have a look at formula-e. 'now' is NOW
Doesn't mater how fast if you can't get back to your charging station.
Same goes for the regular cars - no gas, no go ;)
Woman reporter seems most interested in how fast. When you use 300kw bursts its hard to get 100 miles.But boy can you go fast in 3 seconds.
+Nikolay Agopyan Yeah, but can you go for 400-500+ miles on a charge? Even my big heavy van can go 450 miles.
Maybe those EV's should have a onboard generator ;)
Teslas are getting pretty close to that kind of range. In the following few years as energy storage systems get better we will be able to drive anywhere and charge anywhere from wind and solar. It will be expensive at first, but very shortly mobility will become almost free after that. It was the same as the first cars were invented.
nonsense, it's a unit of measurement, it doesn't change between gas combustion and electric conversion, or any other type of energy conversion, not a physics major are you? :)
as to you're physics laws are wrong claim... prove it. simple as that. 400% efficiency, I doubt it somehow. IT'd be wonderful if there was a way... but like I said... I doubt it somehow....
stii vorba,decat mult si prost,putin si bine,da nu de asta ii vorba.
Daca stii conduce meri cu cat vrei si traiesti mult
If ya cant go 200 miles, its only a run about round town. Lot of $ for that.
Then don't live in rural areas.
You say 400 hp but it is not same. 400 hp electrical motor is more powerful and faster from 400 hp petrol/diesel engine.
Petrol 400 hp 300 N.m 10 000 rpm. 30% efficiency
Electric m. 400 hp 600 N.m. 10 000 rpm 90 % efficiency
And now who is more powerfull and faster ?
Physics laws half of them are wrong !
It same when thay say you can not get more energy from input ahah only in joke.
I have electric gen. input 1kw output 4kw and power up entire house. And to tell me it is not possible heheh
que pena da ver un clasico arruinado!!!
What's the car's 0-60 time?!! Who cares about top speed.
