Most powerful Modern 70cc chainsaw! 

You are supplying an awesome tool for customers to use when deciding which chainsaw they would like to purchase. It’s great to see how groups of saws stack up on a dyno graph.

I've owned 6/8 of these saws and I've settled with the 462. Its the lightest and has the best handling out of the lot. Doesn't feel bulky in your hands. Limbs well due to high rpms and will pull a 32ich bar just fine if your chain is properly sharpened with proper racker depth. Its a brilliant saw for being 72cc. I sold my 500i after 1 week of use as it just wasn't as handy and easy to use as the 462. (found it bulky like a 661) just my personal experience's. 2 and half years of use on my 462 with roughly 50-75 tanks of fuel per year. Not one problem with the saw during my ownership. Food for thought - Mac

I bought the Echo (personal use).....it was the price and better warranty for me. I've only had the chance to run it once....on a large oak. It cut like a dream.

Many thanks to you Joe! I was always thinking how would these saws manage on a real dyno and now I know that. And thank you also for showing the metrics.

Great vids Joe. I have a 565 Huskie and I got to tell ya It took 12 tanks of fuel to break her in. And I’m telling ya its a ripper. Love to see a fully broken in 565 do a pull. Keep up the great work👍👍

Your dyno videos are so interesting and informative Joe, thanks for taking the effort to share. Confirming my thoughts on getting a 372xp OE and getting it ported for a great little firewood saw. Best wishes from Western Australia.

Joe thank you for the very complete lineup. Could we please have a 60cc saw test next.

500 views an hour!!! Killing it Joe!! Thanks for the awesome videos

I needed a bigger saw for some big oak trees that needed clearing so I made the excuse to but an Echo 7310. I love it along with my other echo saws. I came here to see how it stacks up against the rest. For the money I paid, I'm really happy. I have a 620 and 4910 that I did a muffler mod and carb mod on after about 5 tanks of gas. I'll probably do the same to my 7310. I did get to use a 500i while I worked along side a crew on a job. That's the most impressive saw I've ever used but I didn't want to spend $1,400 on a saw I only need one a year. The saw I use the most is my 4910. It's light, powerful and 100% reliable. I love you videos man, thank you

Nice to have a little more than guys' impressions to go on, thanks for putting in the work

I've always claimed & believed the 572xp out runs the 372 but it's cool to see the numbers. Thank you

Having viewed your charts a few many times now I can follow your pointer to get it.

Great comparison! The 462 really showed up to be down so low on displacement. Just speaks for the engineering of that saw. I run my 462 in hardwoods with a 25-28" bar and full teeth chain and is an awesome saw for felling and limbing in a production environment.

Nice work Joe! Thanks for all your work!

Most comprehensive saw video ever, awesome man

Right on👍 Thanks for information. I'm glad I got the 461 over the 462. She pulls a 32' nicely for me where as it looks like the other may have struggled.

Awesome vid, just milled some Russian Olive yesterday with the 500i. The 500i really does run nice under a constent heavy load.

That was awesome! Can’t believe I hadn’t seen it before now. Picked up a couple of the last 7900’s just because and glad I did. Needs some carburetor work but even still I was impressed enough to get a little ea5000. My old late 80’s stihls (034,044,066) still run like new but getting worth enough used to stop running them as much. 👍🏼

Great video i have a 461 and run a 20 inch bar full chisel for most of the year that saw is an absolute workhorse. Non ethanol fuel is the key

Love the video! Always wondered how they compared against each other.

Another awesome video Joe👌 very helpful since there are a lot of factors when choosing a saw.

Awesome test Joe.A comparison of different fuels and or oils would be cool.

Nice test video! I would be interested to now see them ported, muff modded and broken in for full potential

What a blessing. Was just wondering which 70 cc saw i should buy. Awesome content

Those makitas are real nice saws, in my country they are literally half the price of the husky/stihl equivalents.

Another great video, I imagine it was a good deal of work putting it all together.

Late to the game here, but LOVE these vids. Good info to help in planning future saw purchases. Thanks very much.

Great info Dyno Joe. Be interesting to see how a Farmertec 372xp copy comes up and a Iron Horse modded 372xp (ported) & 372xp (86cc). @Ironhorse sent many of us here 😊

Great job. Sure gave me insight. And proof in the pudding about the 462 lack of bottom end being a short stroke saw. It's my favorite no doubt for my needs. I wasnt surprised the almighty glorified 500i barely makes more power then a 460,461. That drop in power on the top end like you said amazes me that under load it drops off. Which load is any amount of cutting at that rpm, to drop of and get it to the midrange? I thought that was really interesting how they all have done that when you put load to it. Anyhow I just think you're Dyno runs on these saws is great, keep up the great work!

Awesome comparo again, Joe, hey just something to remember in regards to horsepower differences between all these saws is that a modded muffler on a 372xp would probably make it in the top 3 for power. The best saw is the one you like to operate the most and last the longest, good work Joe.

Awesome video! Really like these comparisons videos

I love these videos. They really let a person fine tune a saw know how to change porting techniques. Will deff change the game of r/d! So the peaks will be little deceiving. One needs analyze the graph to fine tune a saws performance. The thing that matters the most is what rpm range are you in in the cut!!!.Which saw gas the most hp and torque in that rpm range!! In that scenario the x-torque, and 572 pulled away from other saws with more power and torge in those rpm ranges where saws are ran! The572 and 462 produce the most hp and torque out of all the saws from 9 k to 12k.

Great comparison Joe. I know that had to take a lot of time.

Awesome video ... the same 70cc contenders woods ported I would like to see... always thumbs up content 👍🏽👍🏽

These are great videos man keep it up!

Great vid. Extremely useful info!!

They say the 572 wakes up after break in , i wonder how much difference that would make ?might make an interesting video testing that

Amazing video! Keep up the great work!!

Another great video. Thanks for posting. It is appreciated.

Awesome video Joe, would love to see what the difference in hp is on the MS500i after putting on one of those barkbox mufflers.

Great stuff!!! Love seeing all the brands without talking some up and bashing the others. Some youtubers are too brand loyal. They all have some great saws!

great comparison video on saw performance; this kind of thing is new and needed in the saw community; awesome job.

Great vid can't wait till the ported shootout of them

They are all so close that you can’t make a wrong choice. Other than the 500i costing 500$ more for not having that much more power. 462 or 572 if buying new. Too bad they stopped making the 461 because it is one heck of a saw

Great head to head, data doesn't lie. Thanks for the efforts you make to put out noticeable content. This whole chainsaw community knows about you and much respect is shown.. Nothing but potential Joe, keep em comin.. SLANT'E

Dude this is awesome! Keep it up.

Another great effort, thank you!

Epic! Great info people have been looking for. Keep it up!!! 🤟🤟🤟

New subscriber and really enjoying your videos you are doing a great job!!

Btw this video rocks ,answers many questions in a great saw world , amazing what’s available and how dyno jo can make them really run the way u want

Thanks Joe

Wow Joe Excellent data. The cubic centimeters difference I’m sure played into results But would be interesting is to take hp per dollar spent!! Take the MSRP and divide by hp output and come up with dollars per HP amount. !! That could make a difference to some people The 500i at anMSRP OF $1,370.00 with a 25” bar and 7.04hp comes to $194.60 per hp!!! Ouch!

Great work Joe!!

My man from "Blackhawk" land you sir like I said awhile back. You're content is on point. Keep the videos comming sir. Take care.

Back in 6/20, you had a stock 572 @ I believe just above 7hp on the dyno. Damn variables.

Nice job! Thanks your work.

Thank u 4 doin this!!

Next you should do a 60cc Dyno run. 311,362, echo cs 590, cs 620,husky 455 and I think the 460.

LOVE seeing the metric weights in there. Thanks Joe. Have you ever tested any of the chinasaws or done any porting on them?

Great information!!! The big winner I see is the 461. Seems like it has the most power and tq low/med high. Only at 10k and above does 462 start winning. None of them are bad choices. Choose your flavor and let the chips fly.

Dang it. I wish I could’ve came up with one of my Original Dolmar 7900’s for this. But even then, the 7901 is closer to one you can buy new, so I get it…it’s hard to please everyone. You’re a brave man Joe🤣🤣🤣

yes the video i have been waiting for!!

Ought to try doing the 60cc class and include a 460 rancher.. that was the saw I started out on and ran for years, these dyno comparisons are what get mad views

I have a 461 and it does have the torque. Had to remove the plastic limiters from the carb adjusting screws because I couldn’t get it to idle. Like at all. I don’t really like the way the saw performs across the board though. I still use it, of course. My go-to saw is my Holzfforma 372. It has been a reliable saw for about five years now and I love the way it cuts. As others have said, a sharp chain makes the saw. I always carry spare chains and bars. If you get your bar pinched in a tree and you don’t have your heavy equipment handy you can pop your power head off and cut yourself free with your spares.

The 372 Xtorq with an MSRP of $840.00 comes to $148.94 per hp! But alas there are other thing to consider as you pointed out fit, weight, dealer dependability, I am a numbers guy so I like to to see $ per HP. Grew up on the meager side of life and like to get the best bang for the buck!

I'm old small engine tech, the large intake ports lower pressure and speed.And lots hog them out. It's fun to watch.

Excellent comparison . . .

Great video!

Very nice Joe

Great test ! I will take my converted 64cc to OE 79cc 7900 Makita ex rental Home Depot saw that I have $450 into over a new Stihl 500i . LOL

Another awesome video!!!

good job joe

Love these tests you’re doing! Any plans for the 60cc class?

I really enjoyed your videos, thanks

Thanks for the info my friend great videos

Great info!

Fantastic!

Excellent video

the 500i is the best saw made its so light & powerful love it

love these videos

very well explained

That's a nice comparison I would like to see just the 572xp an 462cm run against each other to many lines is confusing lol. Put a Muffler modd on them both run them again be a nice turn out

Great info and video! :) 🤝🤝🤝

One of new favorite channels, I love the variety of content. Maybe in the future dyno viewers chainsaws, or a saw between a aftermarket rebuild and oem rebuild

Nice, thanks a lot.

Great video

The 462 edged out the 572 in stock trim. Surprising. The 462 needs that extra 2mm stroke that the 461 has.

I like saws 70cc and larger. I have a 462 and a 441. The 462 feel torquey in comparison to the 441. Even though people complain about the torque of the 462, it is better than a 372. I also have a farmertec 440 and 372. I don't have much have much run time on the 372 so I can't comment on it. I think it is going to be good. The 440 seems to have torque about like a 660. It is a very good cutter.

Great information and i love your videos. What do you think of the Echo especially for the price? I feel like with few tanks and a proper tune it would be a bit more competitive.

Pretty damn good numbers from the 572xp. Interested to run that 461 vs my ported 572xp. It should wallop it pretty good. I'll be testing them with either 25" or 28" bars in hardwoods.

Really a good test with even a better expanation. Like the americans say, there is no better subsitude for power than cubic inches. and maybe more important, for torque when you compare the 461 and 462. Maybe a nice upgrade for your video's, give the factory displacement, power and torque and weigth vs your measured numbers. (not for displacement. ) keep up the good work. like your channel very much.

Nice work Dyno Joe! 👍 ... I appreciate all the hard , painstaking work you are putting in. Definitely putting some chainsaw “myths” to rest. Your straightforward no BS approach will take you far. Lotta guys yappin and beatin their chests out there. Refreshing to see someone giving the “straight-goods” !

Great video thanks! I'm curious as to why you pull the starter cord when turning the saw off though?

I'm not surprised the 462 was 2nd, that saw is an animal

This is great!!!

Great video.

Thanks Dyno Joe for this analytical saw info - fascinating stuff! About the hole in the 500i dyno graph at the upper rpm range... do you think that was done to look favorable on European emissions testing? Is the ability coming connect a computer to the saw's fuel computer and change the fuel table like they do when "re-flashing" engine control units (ECUs) in cars to correct the air/fuel ratio across the rpm range?

Thanks for adding the not as well known Makita/Dolmar.

Awesome vid Joe! Love the 462, quick question why do you pull the cord out when shutting it down ? Thanks

It amazes me that the echo ranked something other than last.
