New DIY Engine Dyno - Road to Most Powerful Two Stroke

[@Isarddubois]

I'm really impressed by your openness about your feelings and psychological state. Second time, after the whole "I'm going to make me a wood cabin" episode. I think there are a lot of men who suppress feelings until they go away, including myself. Respect for this, next to the 2-stroke stuff.

The way for men to deal with feelings (whether you recognise them or not) is to build stuff :)

If more people did, it wouldn't be something people would ever be ashamed of. It is much healthier to talk about your issues than let them build up inside l.

[@Freeman12457]

@@joshg218 it’s much easier to accept life is a bitch and feelings don’t help. When you don’t feel you don’t get depressed or anxious and you do what’s needed to survive as a man. You don’t need to “feel” to protect and care for people you love. you don’t need to feel love but you can still posses it. Feelings turn men into mouses. Being is the saviour.

I had a very traumatic childhood because of physical abuse, amongst other forms of abuse. I joined the Marines where I piled on more trauma of a different type. I ended up homeless for about 12 years after I was discharged from the Marines. I was eventually diagnosed with Complex PTSD. I understand what unresolved trauma can do to a person. It nearly claimed my life. I really appreciate your openness about what you are going through and how you are processing all of it. Your testimony can really help others to find the courage to seek out help. Things had to get really bad for me before I became willing to deal with the many layers of mental dysfunction. Hopefully others watching your video and reading these comments will be provoked to seek help, and not have to suffer for many years like some of us have. Keep up the good work and take care of yourself. We need you to thrive so we can get our Stuffing fix. 😁

Mental illness and anxiety is not something to be ashamed off or need to explain yourself you would be surprised how many people have these,s problems. Your doing a great job I look forward to your videos every week. Keep up the good work pal.🙂👍

[@Enjoymentboy]

The mentioning of feelings is something i tried to teach my children. I've found most people don't even really understand the emotions they are experiencing and so they do not react or respond appropriately. Shame, frustration and anger are all "hot" emotions and can initially "feel" the same but they are very different and once you allow yourself to actually experience them THEN you can respond properly. Most people never learn to do this It's like that old saying: When angry count to 10. When really angry, swear. The counting to 10 gives you the time to actually feel what you're feeling so that you can honestly tell that you're angry instead of ashamed or frustrated (for example). Learning how to feel your feelings isn't easy and it's something that many people NEVER learn to do. Good on you for trying.

[@JGollez]

ah, so that's how you do it...I was wondering for some time by now...

[@cuylerleonard3920]

Hey man, as someone that struggles with very similar mental issues, I can fully understand. All I have to say is the fact that you push through and get things done regardless is massively impressive. Some days no matter how motivated I am, I can't get myself to work on my bikes thanks to that fucked up head, but hearing you talk about your struggles really helps me see that it can be done :) I hope the bad days become less and less common for you bud 🤙

[@positivemasculinity42]

Hi Alex, looks like you're not alone in your struggles. I can relate to what you are saying as far as Emotions. I'm 67 and have been battling with this stuff most of my life. Keep on doing what you are doing, it's a ongoing process and the main thing is that you have some insight into what's happening to you. I encourage you to keep at it and have a break when you need to, I am sure we''ll all be still here. As far as the Engine stuff I just went back and re watched the Video where you went to the Roller/Inertia dyno and one of the reasons was the Load Cell Vibration making it difficult to get an accurate reading from this Engine Dyno. Could this set up still have that issue? Happy Festive Season to You and your Family Pete

45 years ago, one of my apprenticeship job roles (as a DC electric traction motor technician) was to operate a Thomas Salter brake horsepower dynamometer. It used a turbine airbrake, for the load, with BHP being calculated from the pounds/foot of torque displayed on the scales multiplied by the RPM, with the total being divided by 5,252. Our small hand built 48 Volts 54 Amp DC traction motors produced 24 BHP @ 2,000 RPM and were supplied to Lansing & Bagnall.

And I must remember you to take a closer look at the EGT since it´s low...maybe there could hide that precious HP we all are waiting for...

[@JaapGrootveld]

I like how you are open about your feelings. The majority of people do not want to feel their feelings and seek distraction. It's a good start to start feeling. But in the end they are just feelings that are generated by thoughts that in turn generate thoughts that evoke feelings. There is something else you can focus your attention on. The silence within yourself. And especially if you dare to feel everything that arises, it is possible to stay with that silence. But now for something completely different. A power test bench with a brake is unworkable. No more investing in it. Immediately switch to a flywheel. Keep it practical and simple, invest where necessary and that brake is useful to stop things again.

I understand your explanation on your feelings. I have spent a large portion of my life staying on the lean and narrow path of logic. I am working on a project in a different field, but it has very similar goals: to be the first at something. What you're trying to accomplish in the shop requires that emotions get checked at the door. Emotion, more times than not, will bring error and skew into your development. Choose a development path, stay on path while taking side notes on things unusual you observe. You've suffered setbacks on the project, allow an emotional reaction to that for yourself. Then there are other matters in life... Sometimes the two seem so contrary to each other. Then there's the cinematography aspect of being a good, KZbin channel. That's a passion in itself! You have many hats to wear. I guess the trick is to enjoy every moment with each of these things. You have been a big inspiration to me to push harder in my goal and feel blessed for finding your channel, its been a good thing! I bet you impact others in the same way...

My situation was in flux so I needed the distraction. I still have the finished product. It's my beloved RG 500 powered Honda NSR MC21. It was the only thing I had left of any value.

[@oliverscorsim]

Perfect. Alex I'm glad you see the why. On the compound turbo bike we couldn't get the clutch to hold to save our lives no matter what we made. Eventually I made a new primary that was much taller and removed the same gearing on the sprockets so it was effectively the same gear ratio in the end. That cut tq the clutch saw 3x and now it actually works great and I can get a whole weekend of 10krpm 2step launches at 35psi of boost dumping the clutch off the line with a flow control valve that slips it and even then my plates have a bit of life in them not much but considering we were getting one pass out of a clutch before that and launching at 20psi and couldn't turn it up to 90psi in 3-4th I think 60psi was the limit before the clutch said bye 😂. It's a much bigger loss there than anywhere else especially with low tq my set up being 155cc and very short stroke it doesn't make much tq but it revs high and we make it think it's bigger by cramming all the air we can down it's throat 😂. So those loses were pretty big and helpful in my case that I didn't have more drag but I needed to make the tq my gearbox and clutch saw significantly less. Wish I had time to work on that bike this year but one day lol kinda did a Dyno run a few months back seeing how far we could push the new turbos and eh 120ish psi is when the head popped off 😂 scary part was the copper head gasket shooting out as it's air/oil cooled lmao. Haven't figured out what I'm gonna do about that yet.

@@MikeyAntonakakis always wanted to play with vgt but never got around to it heard it's not fun but Iv seen some ppl have good success with Arduinos

[@MikeyAntonakakis]

@@oliverscorsim I got it working pretty well - it’s got electronic actuator controlled over CAN bus. I run Megasquirt 2 (which has CAN data broadcasting) for engine management, and use a Teensy on my custom circuit board (CAN transceiver, VR signal conditioner, relay control, wastegate solenoid control, thermocouple amp for EGT, 3-axis accel). The Teensy gets the CAN data from the MS2 and runs an algorithm to control wastegate and VGT, sends CAN commands to the VGT at 20Hz and does dual-solenoid dome pressure control for wastegate. It was tricky to get the algorithm dialed in but I have it working quite well now. Basically, during cruise and coastdown and stuff, VGT is wide open. When boost demand exceeds MAP (based on MS2 boost target table, realtime data coming over CAN), the VGT closes partially depending on engine RPM and current boost level. The more you close the VGT, the faster spool you get, but only up to a point. Close it too much, and it creates too much restriction in mass flow and decreases power into the turbine, so the difficult part was mapping out that response to find the peak at all engine speeds and boost levels. While we are in “spool mode” the wastegate control applies high pressure to the top of the dome (air compressor and tank in the trunk), since the VGT can produce enough exhaust manifold pressure that it pushes the wastegate open lol (especially with a light wastegate spring). Once it gets close to the boost target, the VGT ramps to fully open (gets to full open basically once boost meets boost target) and the wastegate control switches to closed-loop dome pressure control at the same time. That way once full boost is met, VGT is wide open and the dome pressure control does the final control of max boost level. I need to get a fresher video, since I’ve made big improvements since I shot the last video. But I do have one on my channel with some data overlay showing it all doing its thing (accel pedal position, engine speed, turbo shaft speed, VGT position, boost).

Looking good!! One small point about the bearing losses - I think you still have some bearing losses, since you essentially have two bearing interfaces (shaft to caliper, and shaft to dyno stand). You can draw a quick free-body diagram, the torque loss in the shaft-to-dyno stand interface will be something like: viscous drag + free-running drag + some percentage of engine torque. Viscous drag would be from any oil the in the bearing and air or whatever. The free-running drag would be any friction in the bearing when there's no load. The last factor would be the biggest, but not very big, and the first two are pretty negligible. It is due to the force applied to the load cell - let's assume the torque arm pushes down on the load cell at 1m radius. At 10Nm engine torque, with a 7.6 reduction, that means approximately 76N applied to the load cell (ignoring chain loss). That means the caliper assembly is pushing *up* on the shaft with 76N, and transferring that into the shaft-to-dyno stand interface. You are totally correct about the loss of the bearing between shaft and caliper assembly being accounted for in your measurements, though. And with a good bearing setup the loss that you can't measure should still be very low (probably less than 1%).

[@2STROKESTUFFING]

😁👍 Quit crushing my reality with math & logic!

[@MikeyAntonakakis]

@@2STROKESTUFFING Not crushing, just expanding! LOL. But you were very clever to set the dyno up this way and measure it this way! And if you REALLY wanted that last

[@raphrath8561]

Bearing loss in the stand-calliper shaft bearing cannot account for any of the power loss as its not moving thus none of the engine power is dissipated there, the only tiny torque that might be present due to static friction would just be restraint forces.

[@MikeyAntonakakis]

@@raphrath8561 Look closely in the video - there is the shaft that the hub for the brake caliper is mounted on. It looks like it has two bearings on that shaft - one between shaft and dyno stand, and one between shaft and caliper bracket. There is no bearing directly between the stand to the caliper bracket.

Yeah, it happens to everyone. As you get older you think more with your heart than your brain. There's nothing wrong with that and it will make you appreciate life more. Just roll with it because you can't stop it and it'll make you a better person and a better dad. I wish somebody had told me this when I was younger.

Best of luck and a merry Christmas to you and your family! 🎅

I mentioned on last video as a possible fix for the belt drive sapping your power/torque by doing a 'Honda - Gear driven cam system' type setup, ie using gears, from engines' crank to input shaft of gearbox, then you'd have minimal losses and a direct drive with no, erm, 'Stretchiness' (?) lol. But, I guess transferring the motor into makeshift frame so that you can drive a brake rotor dyno could work too (especially IF you can run a long enough chain so that the brake rotor is sunken into a bucket/large tub of water to allow for multiple/longer dyno runs) could be the trick 🤔😏😉... Hopefully (🤞) fella this resolves some dyno testing/power level loss issues... Note: MAYBE using the car brake disk rotor could be better as its mass is higher, so you could use that to help calibrate for power/torque runs (as obvs the motor will fight to spin it up and keep it spinning (again, especially IF the brake disk rotor is submerged in a big tub of water as the 'Air cooling fins' between both surfaces would also interact with the 'Thicker' water too giving more resistance to 'Spin up'???) 😎🇬🇧
