Turned out she was pulling the choke out to hang her shopping bag on, Went like a scolded cat once I worked that out.🤪

When I was Kart racing, I had a similar ignition system. There were companies that made retarder boxes you could add on, to allow higher initial ignition, which then backed off timing by so many degrees per revs. (Amount was determined by what was required and the boxes were tuned as appropriate). I would think something like this with a variable exhaust length would go a bog way to improving power band.

An exhaust valve which could change the exhaust timing (power valve) would be able to help your pipe wave timing issue. More duration would allow for a high rpm timing with the same pipe, shorter duration for low rpm. At least using the port timing formulas for pipe effective length from Blair’s design of two stroke engines.
@marcelpursche53393 жыл бұрын
I think he intents to use this engine only at full throttle and resonance rpm. Kind of like a stationary engine that would always run at a constant rpm. The clutch and CVT will ensure that the engine rpm(under load) can be the same no matter the speed of the vehicle. So a very narrow power band isn't an issue.
@brannonhudson68683 жыл бұрын
@@marcelpursche5339 I think that there’s very clearly an issue with the high crankcase volume not having enough scavenging at below peak rpm, so he cannot spool the engine up under load properly. Only real solutions for more scavenging (beyond piston/port) on a two stroke is pipe induced scavenging or forced induction. If he could have a clutch that kicked in at higher RPM this would clearly help it reach the rpm, but the load from the dyno might still bring it down enough for problems. Perhaps upgrading the ECU to programmable would help get the spark timing to help with piston/port scavenging as well. Complete engine management across RPM and Load is key, and is the difference in a good engine and a good-enough engine.

From my experience wave action tuning NA 4 stroke engines, the Intake tuning is always a lot more powerful than the exhaust. You can have crazy gains with intake runners (+20% to +30% BMEP) that are tuned appropriately. But I guess it works differently with 2 strokes or the RPM is so high that that short runner on the carb is sufficient enough? Maybe that is worth looking into?
@sersge3 жыл бұрын
i heard if you got intake in a range where some resonance charging might happen, you will never get it right with the powerband from the exhaust and it somehow hinders power.

This was the resonant frequency of that space. The powerband example you demonstrated and also noting that it works best at a specific rpm, and as such the peaky nature of a tuned 2 stroke is the same type of thing. Its the resonant frequency of the pipe shape that determines what kind of tune your engine will have. Ive been told skinny pipes tend to be higher rpm speed pipes, and big bulbous ones are for torque.

Good messaging. If the stinger pipe is placed within and centered in the expanded zone of the pipe you will have a much stronger resonance without problems of exit restriction due to this placement. I read an article about this during the 1970'2 and decided to try this on my already strong 125cc Sachs. However, I also added an approved Chrisman spark arrestor on the end of the stinger which likely didn't enhance the power itself. Stronger throughout and especially on top as recorded by my "butt dyno" and multiple drag races with my buddy's 250 yammie. Try it sometime on one of your known engines. This is not crap.

Great video, Alex, on so many levels. We could all make the comments section so much more enjoyable, if we would take the time to read what is posted before commenting. If someone else has already posted an identical thought, just give theirs a thumbs up. That way we don't have to read the same suggestion 50 times. I love reading everyone's comments, but our collective time is valuable.
