As to the dyno hp claims you are thumping your chest about … a stock 361 is rated at 4.4hp per STIHL. Here on the graph we see the corrected hp as being almost .9hp greater on a stock saw or almost 17% more … Therefore , IF we are being intellectually honest then we need to take this into consideration when determining true gains. Heck if a stock 462c has 6.0hp but the stock baseline on joes Dyno is 7.0hp or a correction factor of around 15% yah , 8.4+hp is easily obtainable - until we apply the correction factor 8.4hp (.15) and the REAL number becomes 7.14hp … IMG_5348.jpeg Fabz givin y’all the straight goods - as always 😂

Enuff with the rubbish , carrying on Here’s some 562xp build action ! I went from the flock filter to the winter hi flow filter and p/u slight gains - on this video the winter filter is on top , on the bottom a max flow strip was placed in the inlet. Best cut 11% quicker. That gives (25+17+11) 53% gains over a stock saw running c83 or 36% gains with same b/c over stock. I have an intake comin from The Duke and I’ll see if I can get more airflow from it . Once I get the intake at a satisfactory level I’ll go into the cylinder and do some “flow enhancements” , if all works out a 60% gain vs stock as shown with 63ps or 43% stock vs my build running same bar/chain. As this is a new model I’m slowly and methodically creeping up on the target 🎯

I figure I’m going to need a lot more torque to equal this built 2100cd with the 562xp both running c83. With the 63ps on the 562xp it’ll be doable no problem-o ….

I’m at a standstill on the 562xp/xpg build until the parts arrive from the Dukes saw salvage. Here’s a 272xp with an early version rowdy pipe. As you can plainly see the saw is making tons of torque down low which is what I’m after - not necessarily high hp at 13000 in the wood , a number the saw will never get to anyways! …

Here’s the utuber that brought these style pipes to my attention. For a long time he wouldn’t show them but now we all can get a glimpse … some erroneously claim they just make noise , not power - rest assured these folk are ignorant … These pipes make most any saw bark and in the case of the 562xp really improve the output! …..

Trying to get the other 2101xp going … it has a 090 exhaust so … the carb is overfueling , suspect the needle isn’t dealing properly and the saw is getting too much fuel …

Here is a Hotsaws101 241c insane-0 vs a Hotwoods 241c in hard maple. The saw on the left was built by Hotsaws101 Jack and the one on the right by yours truly. I have a WHOLE slew of videos showing comparisons of my saws vs others not yet released …

As we can see the 2101xp is a fuzz quicker in this wood. It has an 090 muffler , a velocity stack and flow work - a stock 2101xp is 6.7hp at 99cc, this one I’ll conservatively estimate at around 8hp. Well pleased how 562xp worksaw build came out! A stock 562xp is rated at 4.7hp at 59.8cc - this one has considerably more torque and cuts way quicker than a stock saw. I could get more from the 562xp and definitely exceed the 2101xp but then it wouldn’t really be an everyday worksaw- more of a gtg / toy saw. For those in the know , the 2100 series Husqvarna can be made to run very fast, like very, very fast. Did I mention they can be made to cut fast? Anyone who claims their 562xp build is gonna walk this 2101xp in ANY timber is either being untruthful or is just ignorant to the comparison. 99cc vs 59.8cc is almost 40% more displacement and I’ve said for years 3cc is a big deal. Of course there are some who will nonchalantly claim otherwise - I say prove it - you can run the test at your location and show the class your results-otherwise you’re just a blowhard regurgitating the “company line”. Some of y’all are dinosaurs and we all know what happened to them 😂🤣😎

I have over 2 million hits on utube so … brother huskihl latest video shows his builds (550 and 560 xp) cutting thru TilliaAmericana - aka known as linden or basswood which is a very soft wood (410) Janka … IF THIS is sugar maple then I’m the King of England ! …
