I love the Hellcat name so much because of jokes like this, the name is unforgettable.

not to mention it's a pretty basic/ rudimentary blower

he should make an agressive cam for that dragstar wraaaaaaaa

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.

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

@@MidMadn Glow plug "temperature" can be used as a robust way to adjust timing on a nitro engine.

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

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.

Agreed, definitely needs more fuel.

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.

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.

You mean it have a swedish accent?

I never saw a miniature super

You’ve never seen one before this video?

@@ryanryan3473 Nope.

@@cenreaper9127 I've seen small engine compilations, and some have the supercharger, but I'm not sure if they are actually forcing air, or if they're just for show

yeah ok

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

@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! 😃

​@@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.

@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.

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 .

What is the adress internet site for these engine please?

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

@@JshDav But i saw the fuel stopping to flow in the clear tube at high rpm. Also try to elevate your fuel tank.

Needs a lawnmower carb!

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

But how do you think he can add more fuel?

@@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.

Agree, but I would love to see how that Boost's on "HHO" the skill this guy has, he could make Tiny Electrolysis device, see how that Boost's. I love to see all his YT Project's, great maker, think all his builds are great. Running on HHO, would be super cool.

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.
