Nice to see some testing on this! I always wondered how much hp my car would lose roughly when the AC is on. I have a 2007 Accord 4 cylinder (166 HP stock) and it does feel a bit bogged down when the AC compressor kicks in
What size engine does that accord have, 2.4 liter? Engines have come along way. 2.0 liter engines make roughly the same power in 2019 models and get considerably better gas milage at the he same time. I only mention this because my current car, 2019 Corolla hatchback, has a 2.0liter 4 168hp and is EPA rated at 32mpg city and 42mpg highway. I live in AZ and have taken a 150 mile trip this summer running the AC the entire way.. being that it was 100 outside. I still beat the EPA rating and got 45MPG. The difference in acceleration is not as noticable as older cars I've been in. Honestly, if I need to floor it to pass, it must shut the compressor off. It feels exactly the same.
@@kevina2052 AC compressor is designed to disengage upon wide open throttle or high rpm. Different car makers implement slightly different, but very similar.
@@kevina2052 In my 2002 Subaru Outback, it shuts off AC and Alternator above 80% throttle. It even says so in the owners manual. I'd imagine newer cars would do even more...
I had a 1990 Nissan Sentra 5 speed manual back in the day. It had a very simple A/C unit, of course. It literally had a blue button to press to engage the compressor. If I shut that off while I was merging on to the freeway, especially going uphill, it felt like I hit a damn turbo button! It was that dramatic.. 1.6 liter inline 4 with about 90hp I believe. So, if it was pulling as much as this Lexus or even half as much, that's a HUGE percentage of it's output.
Kevin A - Bro that comment made me laugh because it’s so true! I have a 09’ Toyota Corolla with a 4cy 1.8L and prolly like 115HP. When the AC is on it drives fine until I need to accelerate quickly…..I’ll hold down the gas pedal and about 10 seconds later it starts to actually get going and catch up, very non responsive……I turn the AC off and all that disappears and you don’t notice a thing.
Yeah that's what we would have thought as well which is why this was so interesting to us. We originally stumbled on this result while doing some back to back testing on some products we are designing for these cars. We accidentally forgot to turn off the AC and were astonished by the power drop.
Ryan Esposito On these year model Toyota's, Lexus, the compressor is always on. It varies freon flow with an internal valve that changes with load demand and cabin temperature. It's a weird system for sure.
It's very interesting. On my G37 it's hard to tell the difference but I could easily tell the difference in older cars for example early 2000's . I'd like to see more tests with other makes.
So, this particular Lexus has a variable displacement compressor on the A/C. While it is handy to see it presents a load, the load is entirely variable based on the temperature settings, outside air temperature, blower motor settings (yes, that blower motor uses HP too), so to say a 10 hp loss really only applies to what you were testing that day. Old school A/C like my Supra has is easy to disable, and the OEM ECM automatically disengages the clutch on the compressor at WOT. When Lexus went with the variable displacement compressors, they lost the clutch so they lost the ability to turn it off easily.
Thanks for the info Lobuxracer! Yeah I think it would be much nicer if it could be fully disabled at WOT like some vehicles. Oh well, the good out weighs the bad on these ISF's so just gotta remember to turn that AC off before we try to race these things ;)
My Genesis 5.0 automatically shuts down the A/C compressor at WOT to deliver optimum performance. However, my 2001 Nissan Altima did not and because it didn’t you definitely feel the sluggishness. Note: The A/C Compressor that Hyundai Genesis uses is a variable displacement compressor which allows it to adjust itself depending on the demand for cooling from the temperature sensor within the cabin, and ECU intervention for WOT operation. My Nissan Altima on the other hand had a fixed/clutch operated compressor. Meaning that when it’s on, it’s always operating at full capacity, and there by draining the vehicle’s performance whether WOT or just simply cruising around. Most Hondas and Subarus still uses this old technology even to this day.
that car was built to turn too!! take her to the track aswell. you have an american sounding v8 and can turn that car is a win win, i took one up to 120mph and it feels like your going 70
@@SikkyTV No that's normal. You are not taking in to account the ac makes engine run 10-20 degrees hotter and causes major heat soak in forced induction cars like mine. I am losing at least 50wheel. I can feel it up top
maximus vonce yes completely right my thermostat is set at 180 degrees I will make a pass at 140 degrees with the ac on I’m at 200/220 at the end of the pass with it off about 170-190 makes a big difference in just 10-20 degrees
And this is why it is said that you use more gas when you use your AC because if you’re trying to drive like Mario Andretti with your AC on in order for the car to do what it was doing without the AC which your butt down describes to you you tend to use more gas to go at your normal pace
Would be a bunch of work but if you're building a hot rod and fabricating your own lines... you could fab the ac line to make a fuel cooler. Maybe get half of the loss back with ac and have a wot ac shut off set up (switch or maths output). Tank with water or washer fluid if you're forgetful, ac and fuel line wound up, close to engine. Lots of work for not much in power but maybe you'd see 5-20hp with real world underhood temps (could probably drop fuel temp very dramatically) and don't have to use ice.
Fun fact, your average car's A/C is at least 3 times more powerful than your average window unit. Your house is pretty much always below 80°, and once it gets to the desired temperature you just keep it there. A car on the other hand will easily exceed 140° in the sun, and is half glass and has no insulation. Not to mention we demand that our car be comfortable within about 5 minutes. It's counter intuitive because a car is so small compared to a house but car's air conditioners are more powerful. Once upon a time there was an advertisement for a semi truck that stated their air conditioner unit had more than enough cooling power to cool a 2,000sqft home. Neat stuff.
As the owner of a stock D16Y7 powered base model civic making a maximum of 106hp, I would rather resort to cracking open my crank windows than A/C on the freeway or on clear backroads for better acceleration and gas mileage
It's a noticeable difference in any car no matter what if your concern is performance... everything counts in large amounts. Turn off your AC, lights, radio, wipers, lose your "extra baggage" - hell, even having a clean car free of dust and debris inside and out helps. If you want every ounce of gas to go toward acceleration, better shut those "power sapping amenities" off!
So what I am not sure of is that when the AC is on, at least on all the cars I have, and you go above a certain throttle position it shuts off the AC Compressor. Does Toyota not do this or did you shut that feature off. I know on my old LS1 GTO you could adjust the throttle position that caused this to happen with HP Tuners. Also as an Engineer 9HP seems like quite a bit.
@@SikkyTV so here's the issue I have a compressor for a 5 ton home unit is at most a 5hp motor, I realize that AC motors are more efficient but 5hp to run a house vs 9hp to run a car ac compressor seems very high. And every car I have owned for the last 20 years shuts off the compressor at wot, not saying your lying just seems a little unbelievable.
Hello, I have 98 camry and I notice this. I have always noticed in other cars the ac seems to use some amp draw and make vehicles bog down some. What is the usual solution?
But no one normally drives at wide open throttle. It will make more sense to test low to midrange at partial or half throttle. Or maybe from a 60mph roll which is when must people look for that extra punch to pass on the highway.
So I have an 08 GS350, which I would like to start planning an LS swap into. I've seen someone swap an LS into the is200. I know the GS platform comes with the V8 option as well so I'm thinking LS swapping shouldn't be a problem. I have some questions though and was hoping you could help me. Any help would be appreciated. Thanks
I personally see a bigger effect on 4-cylinder engines than on 6 or 8 cylinder not only from displacement but because you have more cylinders firing and overcoming the constant and continuous load of air-con compressor that keeps the engine parts from swinging naturally drag-free as when A/C is off. Can you test sub-optimal variables and their effect on power including: 1. dirty air filter 2. old 12V battery 3. old oxygen sensors 4. worn spark plugs
Thanks for the clarification, was wandering about this. I have the exact same car and recently had it tuned to find out the a/c was left on. So would i be right to assume that the tune is still good, but when i drive around without it on, i have that little extra more OR does it mean it somewhat limited the amount the tuner could do his thing? Im not going to bother going back to retune for such a small variance but just curious.
Technically it should be fine but the tuner may have made adjustments to try and compensate for the lower power outputs he might have been seeing if it was dyno tuned. It definitely should be tuned with the AC off but I don't think it would cause any harm or hurt the tune in a major way.
Yes to get a full AC delete number but we were just interested in what it would do by simply turning it off since most People wouldn’t delete working AC on a street car. Would be interesting to see though
How much would you gain by bypassing the compressor all together? Begging the question iz it really worth it to have no ac in your racecar? Obviously in competitive drag your looking for every hundredth a second but events like rocky mountain race week drivers are driving hundreds of miles is really worth the power gain to sweat your butt off
I had VW Lupo for sometime. With 1.0cc engine and i think around 50 HP. Up hill with AC on, no chance impossible. If its long hill no way. Now i have Fiat Stilo with 120HP multijet engine. It feels the AC i need to push throttle a bit when starting to move but thats all. This video is true but the bad thing is this is HUGE engine, in Europe too expensive :) and i think, im electronics ebgineer i know a bit of mechanics, i think big engines can use their inertia more efficently, because of heavy pistons and crankshaft and AC has small effect. But tiny eco engines unusable with AC.
good question. Only way to find out would be to test it. The pulley itself won't make much of a difference so I would suspect the results would be similar to this giving all other factors equal.
SIKKY I’ve taken my serpentine belt off. I found a Toyota 12 V water pump for $32. It’s electric. I can put it in in line. So now my car has no belt. I was getting 94 miles to the gallon for the last 300 miles on this particular car. I’ll let you know what the new mileage will be. I have a 2000 Honda Insight. I have another 2000 Honda insight that I have 10 modification on. I reduced its factory weight by 170 Pounds. And I have a hot modified fuel line that goes into the fuel rail and --the injectors put the gas in the motor. But it is super heated gasoline --have orifice in the line to control the volume of gas the car burns. This car gets 150 MPG in Fifth gear. At 50 miles an hour. After it has been driven 4miles and everything is warm and hot Look up leanburn .The superHeated gasoline improves the O2 sensor and ecu relationship.
damn my k10 1.0 litre engine has only about 67hp at 6k rpm which is the redline. So in normal rpm range hp should be way less like 30- 40 or something, 10 hp is like minimum 25% of the power. No wonder it feels damn slow with the ac on.
When your AC compressor is in good working order. These people with clapped out compressors been running since they bought the car. Highbeams on full constantly too.
But then again this is a big engine with heavier rotating weight so hp loss is very little but try that with a smaller engine then hp loss would be bigger.
These Dynapack dyno's are extremely sensitive. We have been able to measure gains just from adjusting spark plug gap changes and even switching to a quality synthetic oil over a mineral oil.
This is why I dont understand certain things. Power is calculated in horses, so why the hell an ac compressor is taking so many horses, a horse in reality can put hell of lots of power. So this is why i cant understand a car with 100hp will drop in power so bad that it will almost stall.. Cmon!
@@SikkyTV All electrics draw from the alternator, which in turn drags on the engine. The better question would be how many electrics could you turn on before noticing an effect
yes you are correct but the draw on the alternator from that fan would not be measurable on the dyno because it would be so minute. Good point though and the reason lots of drag cars don't run alternators to get every last bit of power.
SIKKY it's not that you're purposely deceiving anyone. But since it was not stated that this car is the exception and not the normal, people will watch and assume no matter what car they have a loss of power will happen at full throttle.
You state that a civic will want to turn off their ac when they want to go fast but a civic compressor will disengage the clutch under high rpm or high throttle making no difference in power.
LOL ok no more AC when I’m on the throttle. Great video review!
Lam Le ha ha, yeah will be like hitting the NOS switch 😂
No Fr ac on I get gapped by cars, ac off I gap those same cars. Maybe a placebo effect but ac off makes a big difference
This video answered my question a 100 percent. Thanks
Glad it helped!

Yes if the compressor is going bad it can definitely effect it
If the same car never had air-conditioning and there is one less pulley for the belt to travel how much horsepower is one less pulley equal to

When your AC compressor is in good working order. These people with clapped out compressors been running since they bought the car. Highbeams on full constantly too.
Yes, definitely makes it worse when clapped out lol!
my hybrid gs450h ac doesnt feel noticeable🤔
I hope your being sarcastic 😂😂😂
But then again this is a big engine with heavier rotating weight so hp loss is very little but try that with a smaller engine then hp loss would be bigger.
agreed!
Turning off ac gets you about 150 hp extra
lol, maybe not that much but does make a difference!
If you are going to race, just turn ac off😅and you will not be in a nightmare on summer😊
I don't get it. AC doesn't not use more than 2500w or so. Which is around 3 horse power.. How would you ever notice that
These Dynapack dyno's are extremely sensitive. We have been able to measure gains just from adjusting spark plug gap changes and even switching to a quality synthetic oil over a mineral oil.

That’s a nice ass Lexus
This is why I dont understand certain things. Power is calculated in horses, so why the hell an ac compressor is taking so many horses, a horse in reality can put hell of lots of power. So this is why i cant understand a car with 100hp will drop in power so bad that it will almost stall.. Cmon!
good question, this use of HP is from a very long time ago so likely has a lot to do with the accuracy of an actual horse vs nowadays. lol.
Wait, a Lexus sounds like that?
Yes sir! A V8 lexus.
That explains it. Now I can stop yelling………nnnnooooo Monica!!!!
×guy revs his car at the stop light×
Me : ×grins and turns off AC× bet
🙌🏻
Invest in a $14 clip on shirt mic
Got one now! Works great.
2,5-3% hp peak difference
yeah, that's noticeable.
This is whp too hp loss at the engine is higher
yeah, was amazed at how much it affected it.
Am I the only one who once felt ac on INCREASED hp?? 😂😂
lol.....yes
Not much difference if your cars above 200 hp.
This car is around 460hp so I would say the difference is pretty big still if we were able to measure it on this car
The question is what about just the regular fan blowing !
The regular fan would have no effect
@@SikkyTV All electrics draw from the alternator, which in turn drags on the engine. The better question would be how many electrics could you turn on before noticing an effect
yes you are correct but the draw on the alternator from that fan would not be measurable on the dyno because it would be so minute. Good point though and the reason lots of drag cars don't run alternators to get every last bit of power.
O 10hp big loss! Sorry you can't hear my sarcasm
10 hp to the wheels is a lot to turn an ac compressor
I agree with husspower, 10whp is basically an intake
This is a deceiving video. This car did get affected. But fact of the matter under full throttle MOST cars will not be affected.
+importdynamicshi thanks for watching. Some will not be effected but most will. No deception going on here.
SIKKY it's not that you're purposely deceiving anyone. But since it was not stated that this car is the exception and not the normal, people will watch and assume no matter what car they have a loss of power will happen at full throttle.
+importdynamicshi ok. Yes I can see how that could confuse.
You state that a civic will want to turn off their ac when they want to go fast but a civic compressor will disengage the clutch under high rpm or high throttle making no difference in power.
SIKKY nice video other than that. Maybe a variety of cars would be good to show some cars lose some cars don't.
