Should have ran the red beard filter without the top cover. Be interesting to see what it did that way. I'd like to see what my 462 does now compared to stock. Base gasket delete, home brew muffler mod, wcs filter hanging out of the cover. I ran it with the wcs filter before I cut the cover and after I cut it it felt stronger. Sucker pulls some air for sure. And it's cooler air now instead of breathing hot air under the cover. Enjoying the content, keep it coming.

I love seeing real results rather than just claims. I was watching a video earlier where someone wasn't a fan of you testing the turbo crank. I reckon if it works and you're claiming that it works then you should have no fear of it being tested and the results shown. If you're selling a mod with claims and they are shown to be ineffective then maybe don't do the mods. I personally would like to have a play at porting 1 or more of my saws just for shits and giggles but prior to doing that I would seriously consider making up a dyno rig.

[@davidgauthier5276]

Great video as usual Joe. I need to get a reschedule date for my 400c. I have 1 suggestion and 1 question 1. As free advertising you should paint the bar on your dyno stand and add your business logo to it. It spends so much time in the video 2. As they since they are 2 of the exact same model why not pick the actual peak power peak about 100 or 200 rpm lower?

[@dynojoemods2764]

Not a bad idea, As for the rpm, I just kept the line the same as the multiple line graph. Slight oversight on my part. Would probably be .01-.02 higher 200 rpm lower around 9700.

[@ciphercode2298]

At the end of the day I want a saw that cuts well,feels balanced,and that diesnt wear me out. The 400c ticks all those boxes. Smooth as silk antivibe,weighs less than most saws in its class,and is cable of both good cutting speed and can handle good size wood. It's pretty amazing how it compares to the iconic stihl 044 that everyone loved. I've never ran an 044,but it was prized for its moderate weight and size and its ability to pull a 28" bar in hardwoods or the 32" in soft. Granted today's 400c could benifit from an improved oiler, but at least nowadays we have lightweight bars and better anti vibe. I'll spend $100 to put a 461 oiler in my 400c. My previous saw was a ms441cm and with a regular 28" bar it was close to 25lb. It got the job done,but it wasnt one of stihls better designs

[@ciphercode2298]

Just picked up my 400c with 25" bar. Absolutely lovely saw. They didnt have a light bar so its wearing a rollomatic es. Still feels better in the hand than my old 441 and cuts about the same speed. I'll probably add some better spikes and a bark box eventually. Idk about an oiled air filter. Seems like itd be a hassle.

Awesome video Subscribed sir! God Bless ya!

Nice one Joe. Did you run the broken in saw with the Red Beard filter? It would be cool to see the potential on it.

[@HairlipButcher]

I like them filters. They arnt a huge gain but I've noticed my saw runs cooler after buckin 3 cord compared to stock filter. Easy and only $40.

[@timhannan4551]

The used stock saw gives 5% more HP (6.24 vs 5.94) over the unused stock saw.....but if we compare the dyno for the unused stock MS 400 (taken from the "MS400 vs MS 044" video) it is only 5.63hp...which makes it a whopping 11% gain just by breaking it in. Can these numbers be compared from one dyno run to another? Or can there be that much difference in two different units coming from the factory? Would really appreciate your take on this, Joe.

[@dynojoemods2764]

That is where it gets very hard. I would say most are within +/- 5% but if you get 1 lower and 1 upper that cones close to 10% you can compare saws from run to run. Best is to do the runs at the same time. Just like done in each of these videos.
