Horsepower, What is the difference?!

So what is the difference between horsepower?! We have seen all these abbreviations BHP (Brake Horsepower), CHP (Crank Horsepower), WHP (Wheel Horsepower) But what is actually the difference between them all?! In todays video we are breaking down what Mechanical Horsepower is and what all of these different types are! Hopefully this helps to clear some of the confusion about the differences. If there is one thing you take away from this video just remember "Wheel Horsepower = Crank Horsepower - taxes)

Crank/brake horsepower is just how much power your engine makes before taxes :) Great video!!!

[@Smeedia]

Exactly 😉🔥

[@MrAudi220]

Good explanation, i know if your new to cars theres alot of stuff to learn, heck i still learn everyday, and i have been a mechanic for 10 year.😅👍✌️👉

[@Smeedia]

Always learning something new, I had no idea where horsepower originated from until I made this video 😅🙏

[@MrAudi220]

@@Smeedia yeah same for me brother, didn't know about mechanical hp's specifics.👍

[@Outlier117]

I prefer to measure my engine power by using the llama thrust equation.

[@Smeedia]

I've had to do that a few times only when converting from turtle power 🤔

[@patrickisherwood573]

must be how many llamas you can thrust out of your way per second

Thanks ma dude very helpful vid. I never ended up being able to go get my wrx thanks to covid but hopefully soon I'll be going to look at some or possibly a st hatch soon. 🤙

[@christopherbroadhacker6663]

I love the videos and as always very informative because now I can trip people out when they ask about my car lol. Question do I need to swap my 2nd fuel pump for E85?

[@Smeedia]

The HPFP? No need to for E85 🙏😁

[@christopherbroadhacker6663]

@@Smeedia are you sure because I have been doing some reading and some say to change the 2nd fuel pump on the driverside of the engine

[@Smeedia]

Never heard or seen of anyone swapping them. Assuming your looking into the norstrom HPFP?

When you were talking about whp, I couldn't help but hear real hp with a lisp 🤣🤣🤣

[@Smeedia]

🤣🤣🤣🤣🤣

[@ObiWanStromboli]

Just wish there was a universal accurate measuring method of knowing your car’s horsepower than it varying when you go to different tuning locations

[@Smeedia]

We need 1 universal system that read the same across the board 😖

[@Leonardo_groeneveld]

Is there any specific method to test each of these measurements unit? I recently did a dyno for my zx636 and it spins a wheel on the test machine, it produces 110hp = i assume this is WHP?

[@TCRTommyHD]

Great video! I never really knew the difference all Ik was whp was always lower than crank!

[@Smeedia]

Glad the video helped to dig into it a little more 🙌😁

[@Cpt_Wyatt]

So brake horsepower is just the engine and wheel horsepower is the whole thing, the entire car with everything on it?

[@tylerm6652]

"Full chooch". Might have to use that in the future.

[@Smeedia]

Go to phrase 🙌🔥

[@4CountDaddy]

I love the word "dynamometer" ... it's a dynamo-meter! It measures DYNAMO! How much dynamo you got..?

[@Smeedia]

Lol I have two in my office 😅

[@nichuynhh]

Got a question about the cyl 4 cooling mod, would you still need to run it with an el header setup?

[@Smeedia]

Yes, the header fixes the exhaust problem and the cyl 4 coolant mod corrects to coolant issues with the head 🙏

[@nichuynhh]

Thank you, was really confused about that

[@flintlights]

Can you go in more detail on how to buy a turbo kit for the 86 platform please? I’m looking into buying one, but have no clue what each segments are.

[@Smeedia]

I can make that happen 🙏😁

[@Smeedia]

How much power are you looking to make, also have to look at turbo placement of where you want the turbo to sit, your budget of course, turbo size

[@flintlights]

@@Smeedia awesome, thank you! I’m looking to make a conservative amount of power, safe on a stock block; maybe aiming for low 300s. As for turbo size, I’m not sure. Budget probably around 4k. A turbo kit I was looking into was JDL, just because I want that UEL header.

[@Smeedia]

JDL is a really good option and the kit that I wish I would have gotten 😪

[@flintlights]

@@Smeedia haha, yeah. I heard great things about them; fitment, quality, and customer service. The only issue is, I have no idea how to order what parts 😅

[@butterflyeffect2411]

i'm about to get my 07 wrx pro tuned. i only power mods i have a turbo back and intake. are there any things that would help my tuner and make it easier / more reliable for them?

[@Smeedia]

As for the tune not so much, an AOS or catch can wouldn't be a bad idea though 🔥

[@codyhendrickson7735]

With that little of mods done to the engine, Might be cheaper to get an E-tune. I personally wouldn't go get a pro-tune until you're atleast Stage 2+ Could save you some time and money.

[@HJ-sn5gt]

Monroney Label. Thanks

[@13abcde]

It seems to me that if brake horsepower is power produced before anything is involved except the engine, then brake horsepower would be greater than any other kind of horsepower. I need more convincing.

[@dreambiggarage]

So for your eg33 are you swapping out your trigger sensors?

[@Smeedia]

I'd like to so I'm not having to use two of them but one I get to the wiring aspect of things ill start digging more into it 🙏

[@dreambiggarage]

@@Smeedia it’s looking like I’m going to have to change mine out to Hall effect to work with my link ecu

[@Smeedia]

Let me know what you dig up for it!

[@eliezer.g9550]

Just recently I’ve failed inspection due to the o2 sensor not ready. I have done about 3 driving cycles going about 55 mph with no WOT and a total of 100 miles. I'm not sure if it's because my car battery is new or the o2 sensor going out. The o2 sensor only has about 3k miles on it. Will reflashing the ECU do anything?

[@Smeedia]

Reflash may help to reset it, could be a faulty O2 sensor like you said as well

[@eliezer.g9550]

@@Smeedia Update: So I ended up reflashing the ECU and still haven’t seen any changes I also ended up replacing the downstream o2 sensor and still nothing. I’ve put about 60 miles on it so far. At this point, I'm not sure what causing this issue.

[@Smeedia]

Are you getting any CELS?

[@eliezer.g9550]

@@Smeedia it's all good now I ended up slapping the stock intake and changed maps with to stock intake and got the o2 sensor set to ready. Anyway, I think that the Cobb tune (Stage 1+BigSF) for their intake messes with the readiness setting the o2 to not ready. I ended up sharing my issue on Reddit and it appears that many other people had the same problem. I hope Cobb fixes this issue and let others know about this before taking their car to inspection.

[@jimmyquan9388]

Imainly say 401hp and 446tq, from the crank, for my big turbo Audi A4 to sound cool but in actuality with drivetrain lost and weight of my car 360-75hp and 410-420tq from the wheel

[@Smeedia]

Still solid power numbers though 🔥🙏

[@jaejae6682]

What is the name of the wheel in the thumbnail please??

[@KALBO_TAE_CORNDOG_Boy]

dodge caravan wheels😅

[@bradgreen987]

Am always puzzled as to why most hp #s are advertised in crank hp. So misleading to me; that # means nothing. Tuners only speak in wheel hp

[@Smeedia]

They want the highest number they can market 🙃 95% of consumers don't care, only the 5% like us 😅🙏

[@REALMAURUZO]

When using power at the wheels, you need to keep in mind that you need to take into account more variables such as wheel size, tire pressure, etc. The same car with different wheel configurations will give you different numbers. Crank allows you to get a more consistent power readings.
