Great explanation sir. I had no idea some guys could get insane amounts of power from a saw until I got my hands on the 460 lite and it opened my eyes to say the least
I did one of ur builds,, xl12 with pioneer 1200a piston, raised exhuast to 106, no base gasket, port matched cylinder to case, opened up trench in crankcase, and opened intake runner to make it more straight,, she pulls chain now!!! Thanks for them porting vids!!!
There is a channel on UA-cam and seemingly there komatsu zennoah 5800 clone is claimed to be 8hp ....I think the man is a little confused with his reading on his dyno
A lot of that is in the transfers. Remember in the book when they were talking about direction of the flow and how moving the direction of flow towards the intake helps higher rpm power.
@@Smittyschainsawslook up some of the stuff by Frits Overmars and Jan Thiel. There is an article written where they discuss thoughts on transfers and it is a good one with nice pictures and clear explanations.
I only list my in cut rpm on videos for testing purposes and trying to determine a gain. It is irrelevant unless testing in the exact same log, with same chain, on same saw, on same etc. I make no power claims tho.
Yah , we can make anything make sense on paper right and who’s this joker here using my icon and name ? The true “dyno” is in the timber - Always has been , Always will be. Nobody “Races” saws on a dyno 😂. We are not driving a wheel here gentleman we are going thru a clutch and a cutting chain ! , unless you live/test saws in a warp bubble where the laws of physics do not apply to you for some reason, You simply cannot (on gasoline and sans expansion chamber) , I repeat , cannot move enough AIR thru the ENGINE to produce USABLE GAINS in the TIMBER correlating to these claims … ol Fabz is after USABLE GAINS, take some cream of the top , thicken the mix where ya saw makes its livin and then slay with the chain. We’ve all known about this for 50 Years 😂
@@fabzacres-blackcat The only part of this comment that doesn’t make any sense to me is the part in which you say that you cannot move enough air to support these claims. It just doesn’t make sense to me at all. The reason why is that I have ran 8hp 65cc saws. Some guys are getting 9hp or more. I have ran this stuff and I can say for absolute certainty that you can feel the power. It kinda surprises you a decent amount when you do run one of these saws. Now if you think 9hp out of a 65cc saw is just not possible then you should check out the guys doing it professionally for the racing world. They will hand your butt to you and it has happened to me repeatedly. Now what I think you are actually thinking is that it’s not practical in a real world situation. For that I can agree with to a point. To be honest I drive a Ford Ranger to work every single day. Now if I owned a 600hp car would it be practical to drive it to work. No of course not. I can bet you with everything I have that I will absolutely drive that 600hp car to work. It won’t be practical but it will surely put a big smile on my face. Why can’t we do it and have fun with it at the same time? That’s why we do it really. Not for practical purposes but sometimes you can find a situation that it is practical. Especially when time is money.
@ U can only physically move so much air thru ports at a given rpm - this is simple, basic physics and cannot be disputed whether you live in Western NY or Michigan or Pennsylvania 🤣… I have software and by taking a mold , with a product called vinamold you can measure all the pertinent dimensions and then input these values and the software can calculate what you have - kinda like an etch a sketch Dyno where you can make small changes and “see” what happens to the engine WITHOUT having to so much as pickup a file ! The more precise/accurate the dimensional/volumetric measurements the more accurate the results in the real world however there is a margin of error maybe 5-7%. IF your talking about “race saws” specifically MADE for fastest 3 cuts then let’s stop Right here … it’s an apples to oranges comparison imho… Sure , with an expansion chamber , perfect setup on a 10 point checklist and the right go-go juice ya can EASILY DOUBLE the output of the chainsaw motor but again drawing comparisons to A ) improved work saw to earn a living with ,! and B) all out piped race saw , is disingenuous and makes everything clear as mud imho. Good day
@ The volume of air a port can move does not govern how much power the engine can make. Not by a long shot. The majority of power being found is through improving the efficiency of the flow and improving the efficiency in which it can capture the energy. Finding big power is more about efficiency than moving more air. The better you get at getting the flow figured out the more efficient the engine runs and the more power it creates. It is an art that takes a lot of practice.
@ its volume AND velocity … Flow is the AMOUNT of air/fuel mix an engine receives/ can receive measure in cfm … velocity is concerned with the SPEED at which said mix moves thru the intake , into the crankcase and then thru the transfers into the combustion chamber where it’s converted to useable power via combustion. Flow is important , more AIR more Torque however the key to increases in power AND efficiency lies with velocity
@@fabzacres-blackcat Yes but don’t forget about pressure. Pressure is an important part in the equation to figure it all out. This is commonly felt with changes in altitude but can also be manipulated in the crankcase. Temperature also matters because volume changes with temperature but it’s not really considered in this form.
Fake news … Fake sock puppet account masquerading as me too ! There’s only one original Fabulous Fabz and YOU ain’t it pal so suck it and suck it good 😂
😊😊 a ported chainsaw will out cut a stock saw any day ported 4 more air flow also makes more HP and a bigger carb and muffler mod no baffle also makes the saw pull better and U have 2 have the right coil on the saw that will let turn the RPMS 😊😊OMG 11 9 2O24

Vary Interesting stuff bud

The trick is moving the torque peak to a higher rpm and have it stay close to peak over a wider range of rpm.
You move the torque by increasing combustion pressure at a higher rpm or more favorable crank angle.
A lot of that is in the transfers. Remember in the book when they were talking about direction of the flow and how moving the direction of flow towards the intake helps higher rpm power.

I’m finding leaning on it hard teaches you a lot about the torque
@@Smittyschainsawsleaning on it with a tach and measuring chain stall RPM is helpful.
@@Super-Dave-Outdoors Just be mindful because the clutch will start slipping when enough torque is applied.
Is there a way to measure torque without a dyno? I cant make the investment for dyno runs where Im at in the game.
Not that I know of
