[@afellowinnewengland6142]

I'm a retired automotive technician so take my advice with a grain of salt. When you install something forcing significantly more air into the engine (Supercharger) you immediately need to recalibrate jetting (or injector tune) to increase fuel delivery- especially on the upper half of the rev range. Bogging on combustion engines is a symptom of fuel starvation. Increase fuel delivery incrementally until the bog goes away. Your goal should be to run slightly rich to keep temperatures down and ensure you won't damage the engine. The other thing to think about is the ignition timing which needs to be recalibrated slightly for forced induction. You may need to advance it a touch. Good luck. FYI- a very cool little engine. I wish we had things like this when I was a kid.

[@ThePower1037]

The only thing I would add to that is since the oiling system in this engine is the fuel, I'd all a little bit more oil into the methanol to keep temps low, also the timing will be hard to adjust, because the glow plugs at boost tend to overheat and pre-ignite.

[@MidMadn]

Seeing that it is a glow plug engine - I don't think the timing can be altered.

[@ThePower1037]

I thought I was hearing something not right , after reading what you said , I was right with what I was hearing. . . 👍

[@fowlplayoutdoors68]

I heard the bog as well in the intro. Was surprised about what seemed slightly poor throttle response. Generally, I expect a well tuned roots setup to be pretty snappy. But, you do have it backwards on the timing. When you compress the intake charge with a supercharger, or turbocharger, the molecules in the intake charge are closer together and this causes combustion to happen faster. Therefore, you need to retard timing from what it would have been naturally aspirated to prevent detonation. The same is true with nitros, which some would call CHEMICAL supercharging.

[@Missed_Apex_GT]

It’s going lean at high RPM mate….add more carbs,fuel and air otherwise it’ll run super hot…great video ❤️❤️❤️ adding boost means the engine will need to flow nearly double what it is now…I’ve built real engines with high boost,maybe look at increasing port size and or bigger valves…you got this bud love your work ❤️❤️

[@dlaw1954]

In bigger engines, bogging down at high RPM usually means too much fuel, doesn't it? Unless everything is getting too hot and it's expanding, causing internal friction? The exhaust looks pretty rich to me, too, but I'm not real familiar with nitro/gas RC cars either, certainly not anything in this caliber.

[@YZ-YZ-]

Likely too much friction at high rpm that the engine struggles to overcome. The blower is probably producing little (if any) added power, while contributing to parasitic losses and heat.

With more air, you need more fuel. Try building a pump and pressure gauge that will give you the right amount of fuel depending on the pressure.

[@bradleyward285]

You can have more pump all day but if the carb jetting isn't big enough it will never get the fuel it needs

[@billynomates920]

@sourand jaded thanks for your comment. rather more detailed than mine would have been (even could have been) i just liked the whoop whoop sound of the miniature supercharger! 😃

[@jsmith1871]

​@@sourandjaded2586the fueling is still an issue beyond just winding the needles out. Traditional automotive carbs suffer in supercharger setups as the vacuum of the blower prevents the power valve from opening under WOT, this is due to it being actuated as the engine vacuum decreases while the supercharger increases carb vacuum as it spins. These hobby carbs don't have any of the circuitry required to properly fuel this application or make use of boost reference and winded needles will just muddy the throttle resolution elsewhere. How does forced induction increase your compression ratio? The comp ratio is set by the material properties of the engine components. Do you mean volumetric efficiency? If so it's directly benefitted by forced induction. A thicker head gasket can reduce the compression ratio which can assist in avoiding detonation. Forced induction enhances your volumetric efficiency provided you can adequately fuel the application. Literally everything hinges on the carbs.

[@kleetus92]

@sourand jaded Only thing I can think of is the carbs aren't designed for that much airflow and are going lean, or, the 2 to 1 feeder can't supply the fuel, might need a separate one for each. You wouldn't think it would need that much here, but who knows. Other thing is might need different glow plugs, might be blowin these ones out.

[@thunderdick6117]

It's not a fuel issue it's an air flow issue. The reason you can hear such an audible whine is due to back pressure in the blower case from the blower being so restricted . They made it like that on purpose and the two very small outlets from the blower are clear evidence of that . This blower was made for sound not performance . That's the reason it's bogging it's not getting enough air you can hear that the blower makes less noise at high rpm because the vacuum from the engine is effecting the back pressure in the blower it's being lowered because the engine is trying so hard to get air . If the air outlets were bigger it would breathe better but you wouldn't get the cool blower whine .

[@stevenboswell4524]

The bog seems to be rpm related, not just throttle position. Which indicates fuel starvation. With a full scale engine, this is fixed by adding a boost referenced fuel pressure regulator. This raises fuel pressure to increase fuel delivery as boost increases. Otherwise, the carbs will be either overly rich at low boost/part throttle, or overly lean at higher boost/full throttle/high rpm. Either one causes a bog. The trick is, applying that to this small scale version. The creator was smart and talented enough to build this incredible engine, I dare say he already knows everything I just typed, but applying it brings up all sorts of issues and requires quite a bit of knowledge. I'm sure the creator will end up getting it tuned right and I can't wait to see the final product!

[@pootmahgoots8482]

You need to increase the amount of fuel coming into the carbs to compensate for the increased amount of air coming in from the supercharger. Really cool setup. I am looking to get some of these engines to build and put on display. :)

[@whitehuayra]

It runs lean on WOT, we can see the fuel stopping to circulate in the line at WOT, the carbs are not designed to be fed high pressure air from the supercharger is my guess. Awesome work. The sound is so nice.

[@JshDav]

It's a draw through set up, the supercharger is actually sucking air (and fuel) out of the carbs and the pushing it into the engine, I suspect it's actually running rich up top due to the suction from the supercharger pulling too much fuel through, it has more of a rich bog sound to it

[@harrypwhite]

Sounds like the mixture is leaning out too much, so you definitely need to add more fuel. Maybe extend one of the existing pulleys outward, and then you can make your own supercharger gearing? Definitely excited to see where this goes. I remember seeing some 'turbo' keychains which were sealed, so maybe you could have a look at twincharging it? Just a thought :p

Seems like there is a great deal of friction in the supercharger itself also - maybe some bearings or self lubricating bushings?

This is soo cool, you'll get it figured out. I think the glow plugs can't keep up with the upgrade. Or it just needs some tuning. Either way, good luck bud, I can't wait to see what you make out of this. I wish they had these when I was big into RC. Lol. But I also don't have the knowledge that you have lol.

[@ahmetbirinci7768]

You can watch keith57000's v10 engine build compilation to see a nicely built supercharger which isnt straight. Also to mention his v10 engine also struggles in full throthle.

[@daviddeaton8430]

When running a screw blower that engine is going to need tons of fuel, it sounds like it’s running way too lean to me, the way it wants to fall on its face at higher RPM’s, those little kit motors are really not designed to run at high RPM’s for any length of time anyway. But I guarantee if you fatten up the full mixture it would run a lot better. I would look into some bigger CFM carburetors for it if were me. Good luck with it .

[@m4d_mark_xtr3me79]

Yeah its leaning out the top end. I would tune the HSN on the carbs to give it more juice. Half a turn out on each. (Counter clockwise) The low speed needle seems a tad rich and your idle could do with being slightly higher. Turn (clockwise) 1/8th But as a first start that went well. It also seems like a backpressure issue if I'm being honest. 30% is actually pretty good stuff, plenty of punch, I used to run byron in my savage and it loved that stuff. That bogging out issue definitely sounds like a fuelling issue crossed with backpressure.

Plus it also could be pulley system isn't the right diameter to feed the fuel/ air to the engine that's required for an improvement over N/A

[@mikethompson9745]

What's not to love about a supercharger of any size? Are you planning to replace the water pump shaft with a idler style?

[@musicauthority7828]

Do you have a way to dyno it? because my guess is you may not see an output increase over naturally aspirated.

[@Demoni696]

Really cool build! Regarding the issues with WOT performance, there are a few things from the (big) car world that might help: Spark plug gap - When you up the boost level you normally need to close down the spark plug gap to get effective combustion. Not sure how this would work with glow plugs, do they make them with bigger or hotter elements? Also boosted motors normally run less timing advance vs NA motors, since glow plugs are always you can't adjust this but I think you would get similar results by adjusting the octane of the fuel. It's a bummer they made the pully on the supercharger so small, would have been a easy way to get more boost. You could create an additional gear box between the belt and the supercharger, to give you more ratios to play with. CNC project time!

[@UnitSe7en]

Yep, glow plugs come in different temperatures. High compression engines need hotter plugs usually.

[@analog56x]

sounds awesome! it definitely looked like the belt was dragging on that water pump cover that you modified though... looked very tight there. i think you might need more fuel for the added air... im excited to see your version!

[@justanotherguy469]

But how do you think he can add more fuel?

[@analog56x]

@@justanotherguy469 maybe bigger carbs, or bore them out? im betting its lack of fuel. with the fullsize cars, if you add forced induction, you have to add bigger injectors for more fuel, otherwise you'll lean the engine out and blow it up.

[@oliverscorsim]

I really wanna see that Dyno brought out for this na, and out of the box supercharged, then I wanna see you millout the top of that blower and make your own intake plate with 4 big carbs. This things lean up top and blowers generally need a 1.5-3:1 intake to outlet ratio. You might get two carbs to flow the fuel if you drill the bore for the needle valve and anyother restriction in the fuel.

[@oliverscorsim]

I don't think the belt has anything to do with it running badly either. Iv built lots of fast big stuff including a tiny compound turbo 155cc near 100whp. I don't think the belts the best but I don't think it's the big problem it's definitely lean.
