As I’m sure your aware Alex; the mixing of Nitro and Gasoline doesn’t work well without a significant amounts of acetone…..a way to get around this is to make a “GEM” fuel (look it up using a VPN set to the USA); on FTY-Racing’s Website. GEM is a Gasoline, Ethanol, Methanol mix that allows you to match the fuel flow requirements of E85 (stoichiometric 9.76:1-AFR), which is less volume than pure Methanol, but still good solubility with Nitro, and a MUCH wider tuning window (the power is basically the same from 0.7-0.8-Lambda with very little change either side of this target w/out any nitro added). Here’s an example if you can’t find an article on “GEM” fuels (see BELOW); that you could then add your Castor based 2-stroke-oil / Nitro-Injection too, and it should mix easily, without much / any acetone. -Gasoline = 35% -Methanol = 45% -Ethanol = 20% I think this would be worth a try (getting it running well on a “GEM” fuel mix), then trying your prototype Nitro injection setup again. Others have commented on this video, that using an external power jet / gravity feed (like a GP 2-stroke) for the Nitro may be a more controllable way to meter fuel (maybe worth a try too). On a different topic; I’m not sure if Nitrous Oxide (NO2) can be purchased in the region you live??? I acknowledge the maximum power potential of (NO2) is a bit less than Nitromethane (CH3NO2), but the maximum potential of (NO2) is likely MUCH greater still than the engine can mechanically sustain for a full-run duration at Bonneville…..100% Nitromethane can achieve (2.3X) the output of a non-oxygenated race-fuel, and Nitrous-Oxide can achieve (2X) respectively, but as said these theoretical thresholds with NO concern for reliability, whereas 1.5X power of N/A seems to be the "upper-limit" in the top forms of drag racing outside of Top-Fuel (see example below).... 20hp from 50cc is achievable (you've been close before) on race gas, therefore with (NO2) 1.5X * 20HP = 30HP......this is a VERY significant increase in power given how little change to the engine / fuel system is necessary (a fuel / nitrous nozzle, solenoids, and a bottle), and the best part is it's adjustable / scalable through jet size changes to the nitrous system, the carburetors tuning would remain similar to N/A, as would the engine mechanically. Keep up the good work (persistence is key) 👍
@fredmitchel1236 no one. I would say 40hp is not possible with traditional 2 stroke design and regular gas 30hp seems more like the limit, but 40hp with exotic fuel should be within reach. it's also possible with no limits, 4 stroke, top fuel power density would make 67hp from 50cc and it could actually use much lower boost/torque per liter but rev much higher "realistically" an inline 4 with high rpm and high boost that would be balanced and have the minimum number of cylinder to have a power stroke matching every compression cycle. a single or even twin cylinder couldn't run anywhere near the required boost pressure but there is zero interest in spending that much money to make a super powerful 50cc that doesn't fit any class in any competition. NA 4 stroke tops out around 300hp per liter (motor gp) so that would be around 15hp for reference with a ~20krpm redline and exotic valves.

In short, it would 'shatter' the molecular cohesion of the gas molecule, creating more of a fog. This, of course, was easier to light off than the normal intake spray, especially on richer mixtures. It is my thought that it would allow a larger injection aperture, reducing clogging. Being electrical in nature, there would be no parasitic drain on the HP figures. Just an old gearhead rummaging around in his memories. Your successes, however small, bespeak your understanding and skills.

Klotz Super TechniPlate : this products viscosity is abnormally high for a synthetic/castor blend. Instead of 22.4 @ 100C it should be between 15 and 20. So I think this has polymers in it to artificially boost the viscosity. Those polymers can actually reduce lubricity at high temps. Products like that are best for street bikes, not race bikes. For a castor/synthetic blend without the street bike additives you can use Silkolene Pro KR2, Penrite 10 Tenths Race Castor , or Maxima CASTOR 927.
Great progress, nitro explosion are very bad on top fuel racing and they only have very short runner lengths from injector to intake valve. And with your volume of the crankcase it could make it much worse, any safety ideas to prevent explosion and injury to your groin,chest and legs? Maybe Kevlar vest draped over engine and frame backbone?
Nitromethane can run very rich AFR. but running an engine on lambda on petrol and adding nitromethane on top will cause the engine to run very very rich, as you are basically asking the nitro to burn completely without additional oxygen, which it can, but it is better with a bit of O2. its a tough mix, and i would suggest the best option is to have two injectors and controlling them directly from an EFI. tht way you can lean out the petrol somewhat when injecting the nitro.. godspeed :-)
Alternatively he could add a powerjet giving him a smaller main jet and putting a solenoid inline with the power jet so when the nitro goes the power jet closes giving a leaner mix and a conventional carb set up on gas with the ability to add nitro.
@@MC-Racing you can mix nitro in the tank, which will make the carb tuned for gas/ethanol run too lean when mixzd with nitro Which requires lower AF ratio. then inject even more nitro to restore the proper AF ratio. just make sure the ratio between nitro added in the tank + nitro injected is correct. it would be much easier to get the injection right in different conditions like Norway/Bonneville with state of the art EFI EFI only would make more sense in my opinion (simplicity, versatility) but Alex seems very decided to keep the carb. I haven't heard about high performance/high revving engines having combustion issues because of injection and requiring carb. you just need the proper injection setup, and being able to play with different fuel mix could help get rid of potential combustion issues.
Bro I love that intro song!, and I'm not a fan of the older sounding stuff either lol. It's always a good day when 2 stroke stuffing puts up a new video!
I've been following you from the start and what you do is fantastic don't ever stop!!! You have finally pushed me over the edge (hahaha) to comment as you are so close to being able to make some real progress but you've got to get to the point where you know accurately the actual fuel quantity per rev. Please embrace your Arduino skills and start using standard (but quality, not ebay poop) injectors fired for know times at known pressures etc. I've been doing my own project along these lines on a 3 cylinder 2 stroke outboard modified for throttle body injection, bosch injectors, a Speeduino PCB (Easy to DIY build) but my own very rudimentary Arduino code. Tuning is a breeze compared to the pain and guesswork I see you carburettor fans going through - give it a go, you won't regret it :)) Final thoughts on this last video - not knowing the mixtures accurately there could be two things that have given you the power boost 1. That the petrol fuel mix was far richer than you thought so that addition of Nitro brings in the extra oxygen to get you on tune 2. You are running a pipe which is a big part of the HP production, you must consider how you are shifting its tune point when you go changing the exhaust gas mix/temperature as you will be when you add Nitro (get your EGT probe fitted???) I hope you find these thoughts helpful and encouraging. Keep going!!!!!
To avoid running into weird nitro mixing with gasoline or pooling in the crankcase, maybe you can spray the nitro in the transfers? You've got pumps that can do multiple bar of pressure now, so that shouldn't be an issue.
Curious if you can use the standard cabruetor with gas, but have a "power jet" that only sends nitromethane into the intake. You need a valve that can turn on the power jet at close to full throttle. The ultimate WOT nitro flow shall be determined by your pressure regulator. Or get rid of the carburetor and have three "shower" jets on a throttle body: two for gas (idle and up) and your nitro jet (full throttle) If only there are nitromethane mechanical pumps out there that are small, enough for this 50cc single...
Thats o great idea, take the head of the injectorhat too. Then you have a way to give more/less!! Look in the bilcross/folkrace guys. They dont like the saab99 kjet. So it will be cheap.
The best song was the closer, 2-stroke darkness! I can't wait for their new album "Stoichiometric nightmare" and the hotly anticipated single "Inertial dynamometer meltdown"
Through my younger years trying to make engines run on nitro, I learned nitro makes no sense. If it's not running right, just add more nitro. Not a little at a time like gas. A lot more. Raw nitro coming out the pipe is normal on a 2 stroke
You can not run nitro, nitro cooling down air coming into chamber, so your engine have more mixture. Bigger boom more wrm wrm. He is running nitro methane it is sort of very flamable liquid.
Since your pulls are so short maybe a pressurised tank with nitro and inert gas, and just a an pulsed injector to regulate flow. A small pressurized co2 1time use type canister as pressure source, and an injector for flow. No risk of particles, fast to build and bulletproof. Just cost of CO2 canisters as a negative.
Nitro is the key to your power search! Its containing the heat which i hear you canbusevwater injection with nitro since nitro expands about 5o times while water expands 200 times when ignited. Love the Channel brother!!!!
For the time being...rather than spending hp on finding an electric fuel pump... Go find a cannister rated for like 200 psi.. The outlet tubing goes in bottom of tank. Another hose on top of canister goes compressed air. Now you can just pressurize the canister and outlet pressure will be any value you desire...just vary air pressure. Choose like SS304 or 316. I have 3 canisters. I do brake bleeding with the little one gallon. Another I time went on a rescue mission...took the 3 gallon and fired up 1969 Porcshe 911...71K miles.. I just fed the weber carbs with like 6 psi...It began its life with mechanical injection..but was converted to carbs... Being an old type 1,2,3 VM wizard....no troubles for me I worked on alot of engines.. When the 911 was worke up...i never really heard of such aggressive race engine sweet sound.. She ran on all 6....i actually filled her with too much oil...not used to dry sump...but I got that figured out...and drained some Then hauled it to Phx. It was my late niece car. She bought it for $9K in 2001 from some old dude that liked her. I wanted to sell in Phoenix to a bigger audience....That old man bought it new in Tucson 1969 Cause I said i would... I looked up some prices...i had no idea I entered Craigslist ad at about midnight for $20K....just to see if would get bites... Within 8 minutes there were about 5 people interested. I told my sissy po you already have bites... Somehow with that ad- a guy was invited& came to look and said take ad off...and put up Sold... He came over...backed off...offered $15K... My sister then took my pictures relisted and sold the red 911 for $23K...around 2014 What does this have to do with the worlds fastest 2 stroke ? Nothing...
easy answer about the rich/lean question.mixing in the tank and in the crankcase ARE different and both conclusions are actually right -if you're adding pure nitromethane to the an existing AF mixture, it will run richer. (adding more fuel but not more air) -id you're just mixing the nitromethane in the tank then it will run leaner (the mixed fuel has lower AF ratio so same carb setting will give too high AF ratio. other way to look at it you are removing some gas by displacing it with nitromethane ) -combination of both could run neither richer or leaner if you can tune it right the right calculation...
You still need to look at the work ALEXLTD has done on electric centrifugal supercharging and methanol intercooling. Substitute the methanol with nitromethane. Instead of fighting corrosion with liquid pumps use a miniature DC air compressor to pressurize the headspace of the fuel tank or tanks.
I had an idea with this the other day bud. Your original pump nozzle set up but add a plunger to the float bowl to kill the main jet during nitro injection. In theory it should work well and fairly easy.
A gm style idle air control valve would be easy to make work and one could weld a mount onto the float bowl that it screws into. Control could be as easy as when the nitro goes on the plunger kills the main jet. Later you could actually slowly kill the gas from the main with its positioning and taper the nitro on for more or less nitro or to control afrs. Nitro does eat rubber and most things.
If thats a cheap fuel pressure regulator the diaphragm in it will fail my get eaten away on e85 in less than a weeks time so nitro is gonna kill it quick. Fabricate better diaphragm now to save headache later
Have you considered using a pressurised tank for the nitro with an air pump to maintain pressure. This option removes all the drama with finding a nitro compatible pump.
Most EFI pumps cant handle sucking through a filter, they are not designed to have restriktion on the suction side, so move the filter. As outhers have sudjested, you could try k-jet nossles/injectors. Regards Erik (swe)
Great watch and loved the music! Just a throwaway question here, but how possible would a direct nitro ejection be? As in it skips the crank case? I remember one of your old prototype engines had a secondary intake that was direct to the cylinder. Having the crankcase getting full of nitro and gas along with all the mixing that happens in there sounds problematic. If you could find a way to have the nitro directly injected into the cylinder skipping the crankcase. Another idea is like the nitro funny cars, they start on gas and then switch to nitro
Poenget med ett filter er å ta unna for slitasje i pumpen (spon) slik at ikke trykkregulator og dyse tetter seg, pumpen får heller ikke nokk tilførsel ved å sette filter forran pumpa og dermed høyere slitasje
If the carburetor for your gasoline engine's A/F ratio is set for peak power at about 12.4/1, then you should be injecting 100% nitromethane at a much richer A/F ratio than its stoichiometric (complete burn) ratio of 1.7/1. As a suggestion: you might choose 1.25/1 as a starting point and then calculate nitro's flow rate based upon the engine's airflow rate at the estimated peak-power rpm. As an aside... you have the ability to measure fuel-flow and air-flow rates...right? By injecting an unknown amount of nitromethane into your engine, you will be lucky if it's too much (rich) and is providing much needed sensible-cooling (there is no vaporization cooling with nitromethane) to the combustion chamber. When running nitromethane at it's peak power A/F, it will generate seriously high temperatures, especially since you're running a compression ratio best suited for gasoline (much too high for neat [pure] nitromethane). Also, since nitromethane is very slow burning, you will need to add a bunch of timing (ignition advance) to get the engine's peak pressure spike within its TDC ballpark. Disaster lurks with retarded nitromethane ignition timing. If the engine has "run-on" problems at ignition shut-off, the nitro is probably (as you mentioned) firing off some component (Spark plug, etc.) that is glowing incandescently within the combustion chamber, which is why top fuel and funny car (drag race) engine-tuners rely on a fuel supply shut-off to terminate a run. If you already don't have them, invest in a couple of A/F flow instruments; eg., an "old school" rotometer for fuel flow, and "calibrated air-flow nozzles" for airflow rate. Wishing you the best, and Cheers!
Nitromethane has a substantial heat of vaporization, maybe not the highest there is but still, and is used in cupious amounts. What exactly makes you think it has no evaporative cooling effect, that makes no sense at all.
I just lost a lengthy reply to this (UGH), so here's the condensed version: Nitromethane, because of its 1/1 peak-power A/F, does not have time to change state (liquid to a vapor); therefore it can't realize the benefits of vaporization cooling. Theoretically, nitro's potential looks pretty good, requiring 258 btu of heat to vaporize one-pound of itself. Compare this to methanol, which needs 472 btu to vaporize one pound of itself... almost twice as much. However, when factoring in the peak-power A/F ratios of each chemical, nitro's prospects to vaporize take a turn for the worse-258/1=258; methanol-472/4=118. Stated another way: nitro will require more than twice the heat to vaporize in the engine than methanol at their peak-power A/F ratios (258/118=2.2). Over the years, while engine tuners have witnessed frost build-up on methanol-fueled engines (carb, induction tract, crankcase, etc.), no such condition is observed with their nitromethane-fueled counterparts. In fact, only a small percentage of nitros vaporization-cooling potential (if any) is ever realized. Instead, nitro relies on removing heat without changing state-a process known as "sensible heat removal", or heat removal by conduction. As an example, in top fuel and funny car drag racing, where extremely rich, near neat nitromethane mixtures are used to control combustion temperatures and detonation, vaporization cooling is ignored; in the minds of most tuners, it simply doesn't exist. Going a step further, only part of nitromethane's fuel charge is atomized let alone vaporized in its flood-like rush to the combustion chamber and beyond.
@@DavidGierke-nl1dl Thank you, that's a very comprehensive and informative reply for a TH-cam comment. So, it has an evaporative cooling effect, it's basically just not significant enough under common A-/Top-fuel etc. conditions to really take it into account. That makes much more sense to me.
if your going to keep it mechanical under high pressure and having a duty cycle solenoid to control the injector eg at certain rpm , directly injecting it into the crank case might offer a smother transition with normal gasoline as with the low atomisation of the fuel that close to the reeds and the nitro cant mix ( it cant mix anyway), but directly misting into crank case at required load might offer better control other than that i would just got to efi
Why not feed the nitro simply by using a power jet nozzle. Then you don't need the electric fuel pump... Wops, I just saw that someone had already come up with the same idea. However I want to add that a second gasoline power jet feed in order to avoid too lean mixture should also be used.
I haven't watched the video all the way through yet, just to where he says he's curious about if injecting nitro will richen or lean the engine. I'm going to make a guess right now and see what his results are. My experience with nitro in our AA/FA car tells me injecting nitro on an already running/tuned gasoline engine is going to lean the mixture. The adding enough nitro to run on both properly without also adjusting the gas circuit is going to displace enough air that it will require much more nitro to make up for it, which will cause the overall mixture to go lean. Now this is based on 100%, we fix the issue of adding fuel displacing air by adding boost. - Now I'll resume the video and see how wrong I am 😂😂
The AI generated songs were so funny, but at the same time it is amazing how good it already works, just like your latest test with nitro injection. A 20% increase with a clogged jet dribbling fuel in is a success. These gear pumps don't like running too dry as there is always contact between the teeth which need an oil film between them to prevent eating themselves up. That's why they are mainly used as lubrication or hydraulic pumps. Could a membrane pump work? problems could be the pulsating nature of the flow and the membrane's resistance to methanol or nitromethane.
I'd suggest you remove all fuel filters from the system and just prefilter your fuel before it goes in the tank. The direct injection bypass is a pretty good idea but you're missing a few things. I know Nitromethane is fun to experiment with but the lessons are expensive. You'll need to add an oxidizer to your Nitro fuel mix. Most people don't know this and it's not a sin to not know something. I wouldn't try injection using 100% Nitro (I'm not going to say "trust me" but I will say you'll find out why I wouldn't if you continue). I had great luck with a mix I called the "sweet 16". You start with an empty 1 gallon jug, add 16 ounces of Nitromethane, 16 ounces of Propylene oxide and around 4 ounces of castor oil (the same stuff grandmothers used to give children years ago), then fill the remaining space in the jug with Methanol fuel. You can play with the mix to make it your own by adding more Nitro if you like, at your own peril (I have blown the top half of engines off of the block by using just a bit too much Nitro). You will not get much benefit out of Nitromethane until you start adding an oxidizer. You'll see what I'm talking about.
I'm a mechanic but my two-stroke knowledge is limited to what I've learned here and with wrenching on my DD671-powered bus, so please pardon my 'two-stroke ignorant' question: Could the nitromethane be injected directly into the transfer tube as opposed to the carb so that it enters the cylinder (mostly) fully atomized? If not, why? Is it just a bad idea, access to the transfer tube, or something else? Thanks! Les Loved the music, BTW! Another outstanding video.

You are running a pipe which is a big part of the HP production, you must consider how you are shifting its tune point when you go changing the exhaust gas mix/temperature as you will be when you add Nitro (get your EGT probe fitted???)
I hope you find these thoughts helpful and encouraging. Keep going!!!!!
Gotta get that song on Spotify.
To avoid running into weird nitro mixing with gasoline or pooling in the crankcase, maybe you can spray the nitro in the transfers? You've got pumps that can do multiple bar of pressure now, so that shouldn't be an issue.
KILLER Killer killer opening music score! Patent it. Copy write it, but PLEASE give us a link to it.
...oh and, good stuff Maynard.
The venture into AI music is pretty successful, quality isn’t the greatest but hey a song about Nitro in mopeds has all of the forgiveness
@@AndrewKay-fg1bj no it doesn't. AI music is not music, it sucks the soul out of the rest of the video
@@TheMarcQ i started to watch this channel to learn stuff. more music = less learning
Curious if you can use the standard cabruetor with gas, but have a "power jet" that only sends nitromethane into the intake. You need a valve that can turn on the power jet at close to full throttle. The ultimate WOT nitro flow shall be determined by your pressure regulator.
Or get rid of the carburetor and have three "shower" jets on a throttle body: two for gas (idle and up) and your nitro jet (full throttle)
If only there are nitromethane mechanical pumps out there that are small, enough for this 50cc single...
You can maybe buy a nozzle from a bosch k jet injection system , it is designed to spray contentiously with variable volume and will open at 3.5 bar .
Thats o great idea, take the head of the injectorhat too. Then you have a way to give more/less!!
Look in the bilcross/folkrace guys. They dont like the saab99 kjet. So it will be cheap.
The best song was the closer, 2-stroke darkness! I can't wait for their new album "Stoichiometric nightmare" and the hotly anticipated single "Inertial dynamometer meltdown"
The music is amazing! Only channel on youtube with it's own AI tailored songs
Hi from Montreal, love your experiments!
Love the Outtro Music!!! Keep up the good Work love this show ..
At the beginning I thought, cool music and strangely at the exactly same topic as the video, now it makes sense 😂
K jetronic injector, regular 3.5bar pump. VW Polo fuel filter with internal fuel pressure regulation. Maybe run the flow valve electronically.
Through my younger years trying to make engines run on nitro, I learned nitro makes no sense. If it's not running right, just add more nitro. Not a little at a time like gas. A lot more. Raw nitro coming out the pipe is normal on a 2 stroke
You can not run nitro, nitro cooling down air coming into chamber, so your engine have more mixture. Bigger boom more wrm wrm. He is running nitro methane it is sort of very flamable liquid.
Since your pulls are so short maybe a pressurised tank with nitro and inert gas, and just a an pulsed injector to regulate flow. A small pressurized co2 1time use type canister as pressure source, and an injector for flow. No risk of particles, fast to build and bulletproof. Just cost of CO2 canisters as a negative.
Until there is a problem, then you have a big spill...
this is just testing for eventually using on his landspeed bike.
the music is hilarius
Finally something that makes sense.. I haven't watched yet.. maybe ill eat my words
awesome vid and even more awesome song playing in the background
How I appreciate an adult style of music instead the usual rock garbage can theme. Thank you for not assaulting our ears.
DUDE!!! The music.... so goood !!!!!
Nitro is the key to your power search! Its containing the heat which i hear you canbusevwater injection with nitro since nitro expands about 5o times while water expands 200 times when ignited. Love the Channel brother!!!!
@@vancemacd6315 how do you ignite water?! vapor expands a lot compared to water in the liquid state, but it doesn't "ignite"
why do 2 strokes make me feel like im dreaming in everyway even working on them i feel they are meant to be
Brother you look more like a mad scientist every day.
For the time being...rather than spending hp on finding an electric fuel pump...
Go find a cannister rated for like 200 psi..
The outlet tubing goes in bottom of tank. Another hose on top of canister goes compressed air. Now you can just pressurize the canister and outlet pressure will be any value you desire...just vary air pressure. Choose like SS304 or 316. I have 3 canisters. I do brake bleeding with the little one gallon. Another I time went on a rescue mission...took the 3 gallon and fired up 1969 Porcshe 911...71K miles..
I just fed the weber carbs with like 6 psi...It began its life with mechanical injection..but was converted to carbs...
Being an old type 1,2,3 VM wizard....no troubles for me
I worked on alot of engines..
When the 911 was worke up...i never really heard of such aggressive race engine sweet sound..
She ran on all 6....i actually filled her with too much oil...not used to dry sump...but I got that figured out...and drained some
Then hauled it to Phx. It was my late niece car. She bought it for $9K in 2001 from some old dude that liked her.
I wanted to sell in Phoenix to a bigger audience....That old man bought it new in Tucson 1969
Cause I said i would...
I looked up some prices...i had no idea
I entered Craigslist ad at about midnight for $20K....just to see if would get bites...
Within 8 minutes there were about 5 people interested. I told my sissy po you already have bites...
Somehow with that ad- a guy was invited& came to look and said take ad off...and put up Sold...
He came over...backed off...offered $15K...
My sister then took my pictures relisted and sold the red 911 for $23K...around 2014
What does this have to do with the worlds fastest 2 stroke ?
Nothing...
This intro/nitro song slaps
Nice blues
The song is great!!👍
easy answer about the rich/lean question.mixing in the tank and in the crankcase ARE different and both conclusions are actually right
-if you're adding pure nitromethane to the an existing AF mixture, it will run richer. (adding more fuel but not more air)
-id you're just mixing the nitromethane in the tank then it will run leaner (the mixed fuel has lower AF ratio so same carb setting will give too high AF ratio. other way to look at it you are removing some gas by displacing it with nitromethane )
-combination of both could run neither richer or leaner if you can tune it right the right calculation...
Let’s see how it behaves!
You still need to look at the work ALEXLTD has done on electric centrifugal supercharging and methanol intercooling. Substitute the methanol with nitromethane. Instead of fighting corrosion with liquid pumps use a miniature DC air compressor to pressurize the headspace of the fuel tank or tanks.
I had an idea with this the other day bud. Your original pump nozzle set up but add a plunger to the float bowl to kill the main jet during nitro injection. In theory it should work well and fairly easy.
A gm style idle air control valve would be easy to make work and one could weld a mount onto the float bowl that it screws into. Control could be as easy as when the nitro goes on the plunger kills the main jet. Later you could actually slowly kill the gas from the main with its positioning and taper the nitro on for more or less nitro or to control afrs. Nitro does eat rubber and most things.
There are reasons why fuelpumps in alcohol classes(dragracing) has steel bodies.
If thats a cheap fuel pressure regulator the diaphragm in it will fail my get eaten away on e85 in less than a weeks time so nitro is gonna kill it quick. Fabricate better diaphragm now to save headache later
Have you considered using a pressurised tank for the nitro with an air pump to maintain pressure. This option removes all the drama with finding a nitro compatible pump.
Nice Soundtrack
Maybe throw an indicator light in-line with the fuel pump circuit so we can tell when you have it enabled?
The smell of the klotz super techniplate ❤❤❤❤❤❤❤
Most EFI pumps cant handle sucking through a filter, they are not designed to have restriktion on the suction side, so move the filter. As outhers have sudjested, you could try k-jet nossles/injectors.
Regards Erik (swe)
Great watch and loved the music!
Just a throwaway question here, but how possible would a direct nitro ejection be?
As in it skips the crank case? I remember one of your old prototype engines had a secondary intake that was direct to the cylinder.
Having the crankcase getting full of nitro and gas along with all the mixing that happens in there sounds problematic. If you could find a way to have the nitro directly injected into the cylinder skipping the crankcase.
Another idea is like the nitro funny cars, they start on gas and then switch to nitro
Poenget med ett filter er å ta unna for slitasje i pumpen (spon) slik at ikke trykkregulator og dyse tetter seg, pumpen får heller ikke nokk tilførsel ved å sette filter forran pumpa og dermed høyere slitasje

I really like the AI music, good job and big thanks!!
Aquamist makes a really good water/meth injection system, they’re based in the UK.
Besides your awesome Video content, I'm REALLY enjoying the (A.I.?) music & vocals!
You should watch patrick garage, he´s done all this testing with mechanical fuelpump,, hint: he runs lectrons now!
If the carburetor for your gasoline engine's A/F ratio is set for peak power at about 12.4/1, then you should be injecting 100% nitromethane at a much richer A/F ratio than its stoichiometric (complete burn) ratio of 1.7/1. As a suggestion: you might choose 1.25/1 as a starting point and then calculate nitro's flow rate based upon the engine's airflow rate at the estimated peak-power rpm. As an aside... you have the ability to measure fuel-flow and air-flow rates...right?
By injecting an unknown amount of nitromethane into your engine, you will be lucky if it's too much (rich) and is providing much needed sensible-cooling (there is no vaporization cooling with nitromethane) to the combustion chamber. When running nitromethane at it's peak power A/F, it will generate seriously high temperatures, especially since you're running a compression ratio best suited for gasoline (much too high for neat [pure] nitromethane). Also, since nitromethane is very slow burning, you will need to add a bunch of timing (ignition advance) to get the engine's peak pressure spike within its TDC ballpark. Disaster lurks with retarded nitromethane ignition timing.
If the engine has "run-on" problems at ignition shut-off, the nitro is probably (as you mentioned) firing off some component (Spark plug, etc.) that is glowing incandescently within the combustion chamber, which is why top fuel and funny car (drag race) engine-tuners rely on a fuel supply shut-off to terminate a run.
If you already don't have them, invest in a couple of A/F flow instruments; eg., an "old school" rotometer for fuel flow, and "calibrated air-flow nozzles" for airflow rate. Wishing you the best, and Cheers!
Nitromethane has a substantial heat of vaporization, maybe not the highest there is but still, and is used in cupious amounts.
What exactly makes you think it has no evaporative cooling effect, that makes no sense at all.
@@heinzhaupthaar5590
I just lost a lengthy reply to this (UGH), so here's the condensed version: Nitromethane, because of its 1/1 peak-power A/F, does not have time to change state (liquid to a vapor); therefore it can't realize the benefits of vaporization cooling.
Theoretically, nitro's potential looks pretty good, requiring 258 btu of heat to vaporize one-pound of itself. Compare this to methanol, which needs 472 btu to vaporize one pound of itself... almost twice as much. However, when factoring in the peak-power A/F ratios of each chemical, nitro's prospects to vaporize take a turn for the worse-258/1=258; methanol-472/4=118. Stated another way: nitro will require more than twice the heat to vaporize in the engine than methanol at their peak-power A/F ratios (258/118=2.2).
Over the years, while engine tuners have witnessed frost build-up on methanol-fueled engines (carb, induction tract, crankcase, etc.), no such condition is observed with their nitromethane-fueled counterparts. In fact, only a small percentage of nitros vaporization-cooling potential (if any) is ever realized. Instead, nitro relies on removing heat without changing state-a process known as "sensible heat removal", or heat removal by conduction. As an example, in top fuel and funny car drag racing, where extremely rich, near neat nitromethane mixtures are used to control combustion temperatures and detonation, vaporization cooling is ignored; in the minds of most tuners, it simply doesn't exist. Going a step further, only part of nitromethane's fuel charge is atomized let alone vaporized in its flood-like rush to the combustion chamber and beyond.
@@DavidGierke-nl1dl
Thank you, that's a very comprehensive and informative reply for a TH-cam comment.
So, it has an evaporative cooling effect, it's basically just not significant enough under common A-/Top-fuel etc. conditions to really take it into account. That makes much more sense to me.
with this setup you can run the nitromethane like nitrous oxide, mixed with gasoline
Success!
Nitro loves compression! Build a high comp head and try it!
if your going to keep it mechanical under high pressure and having a duty cycle solenoid to control the injector eg at certain rpm , directly injecting it into the crank case might offer a smother transition with normal gasoline as with the low atomisation of the fuel that close to the reeds and the nitro cant mix ( it cant mix anyway), but directly misting into crank case at required load might offer better control other than that i would just got to efi
had a little moment there at the start before i remembered that AI is a thing...
i could not believe what i was hearing! 🤣
Holy sh*t this is the best song I have ever heard! :)
Why not feed the nitro simply by using a power jet nozzle. Then you don't need the electric fuel pump... Wops, I just saw that someone had already come up with the same idea. However I want to add that a second gasoline power jet feed in order to avoid too lean mixture should also be used.
I haven't watched the video all the way through yet, just to where he says he's curious about if injecting nitro will richen or lean the engine. I'm going to make a guess right now and see what his results are. My experience with nitro in our AA/FA car tells me injecting nitro on an already running/tuned gasoline engine is going to lean the mixture. The adding enough nitro to run on both properly without also adjusting the gas circuit is going to displace enough air that it will require much more nitro to make up for it, which will cause the overall mixture to go lean. Now this is based on 100%, we fix the issue of adding fuel displacing air by adding boost. - Now I'll resume the video and see how wrong I am 😂😂
Came back just for the song 😂
The AI generated songs were so funny, but at the same time it is amazing how good it already works, just like your latest test with nitro injection. A 20% increase with a clogged jet dribbling fuel in is a success. These gear pumps don't like running too dry as there is always contact between the teeth which need an oil film between them to prevent eating themselves up. That's why they are mainly used as lubrication or hydraulic pumps.
Could a membrane pump work? problems could be the pulsating nature of the flow and the membrane's resistance to methanol or nitromethane.
nitro moped blues .......... thank you
Can you put an inline fuel filter between the electromechanical pump and the nozzle?
I'd suggest you remove all fuel filters from the system and just prefilter your fuel before it goes in the tank. The direct injection bypass is a pretty good idea but you're missing a few things. I know Nitromethane is fun to experiment with but the lessons are expensive. You'll need to add an oxidizer to your Nitro fuel mix. Most people don't know this and it's not a sin to not know something. I wouldn't try injection using 100% Nitro (I'm not going to say "trust me" but I will say you'll find out why I wouldn't if you continue). I had great luck with a mix I called the "sweet 16". You start with an empty 1 gallon jug, add 16 ounces of Nitromethane, 16 ounces of Propylene oxide and around 4 ounces of castor oil (the same stuff grandmothers used to give children years ago), then fill the remaining space in the jug with Methanol fuel. You can play with the mix to make it your own by adding more Nitro if you like, at your own peril (I have blown the top half of engines off of the block by using just a bit too much Nitro). You will not get much benefit out of Nitromethane until you start adding an oxidizer. You'll see what I'm talking about.
Didn't you play with an Arduino PWM circuit a while ago, you can control the Plan B Fuel Pump with that and a relay...
Hahaha😂 best intro so far. 😂❤
I'm a mechanic but my two-stroke knowledge is limited to what I've learned here and with wrenching on my DD671-powered bus, so please pardon my 'two-stroke ignorant' question:
Could the nitromethane be injected directly into the transfer tube as opposed to the carb so that it enters the cylinder (mostly) fully atomized?
If not, why?
Is it just a bad idea, access to the transfer tube, or something else?
Thanks!
Les
Loved the music, BTW! Another outstanding video.
You ask too much but request a question mark and paste it. Yes/No???
@@magicbox9371 just copied yours. Thanks
Would injecting a little bit of diesel as soon as the nitro is turned off help?

Switch to running the engine on methanal, nitro mixes verry well with alcohol.
Are you always using the same heat range plug, or changing depending on how rich or lean you are trying to go?
needs timing as the flame front will change when adding nitro
haha, "plan b is my saviour" , den er litt mørk tatt ut av kontekst
Loving the AI music :D
Wtf the music? Jajaja excelent
Are you allowed to show you have nitro now ?
That isnt a "Injector" stop missleading everyone. If you used a proper injector this wouldnt be a issue.
Would direct cylinder nitro injection be an option?
