1/4 SCALE V8 Engine Gets TUBULAR Exhaust System!

[@o0julek0o]

Now it sounds like a full sized engine, I swear.

[@lawnmowerdude]

You can get the sound of a full size engine by carefully timed popping sounds too.

[@dyllanneedham2087]

Imagine how it would sound with individual throttle bodies

[@gvii]

Boy, that thing has been a real pain to get up and running properly. But holy heck, does it sound fantastic now that you have it running right! I could just sit and listen to that thing run and be perfectly happy, lol.... Good to hear that the motor didn't get cooked when the water and oil pump wasn't running. Can't wait to see what you end up doing with it once you get all the bugs worked out.

[@fightuntil996]

The sound with the new muffler/exhaust is amazing.

[@RANnewlife]

That growl from such a small engine. Soo satisfying

[@tylerpoore97]

Bro. You are killing it. Been following you for YEARS because of literally no one else putting in the effort(actually having the tools to do so as well) to make these crappy toy engines/models actually run. Massive props and congrats on the subscriber boost lately!

[@bluespidergaming7719]

im trying to give me some credit engineering is hard

[@Matt_Deluca]

Although I think it's neat that such an engine is available, there seems to be a lot of engineering fails with it out of the box. Perfect content for you! But I'd be upset if I bought one of these and had this many problems. Sounds great with the new headers though! Nice job

[@jackradzelovage6961]

its chinese made. they dont care if it works :/

[@heckin_dinosaw]

I believe the reason for slot of these fails is that these kits are usually sold to be a display piece, that can be capable of running, not as an actual motor designed to run, this why so much stuff usually has to be redesigned for it to run reliably, but I agree, for the price of it they should be designed much better

[@2Skinny]

Especially since you can build an LS from junkyard parts for how much this thing costs.

[@paradiselost9946]

if i bought a conley precision, and had these problems from the box... id track them down atnd throw it at them. but for about 1/4 the price, one can expect dodgy crap from china.

[@heckin_dinosaw]

@@paradiselost9946 what ever happened to Conley? I know they had a building fire but did they ever recover from that?

[@tiporari]

Exhaust length and presence of crossover such as H or X pipe have a big effect on sound. It would be an amazing thing to experiment with tuning the exhaust to get different tones from the engine.

[@MiGujack3]

8 to 1

[@matthewmondragon2074]

Could be, however the important part is trhowing away the gases to the the cylinders more cleaner, if we focused much into the sound some of the gas could be still stuck and mess the combustion, thats why most of perfomance/racing exaust pipes have bigger diameter, and the sound? Well is secondary. Could be great if its try replic or make similar to the Ford GT40's exaust type, to start it simple.

[@exoticcreature3059]

I don't doubt that sir but the H and X pipe less effect on sound that's you think due to the fact that the header primary length is fixed in the and so is the engines firing interval. Those two factors didctate sound the most. H and X pipes are mostly for scavenging and balancing pressure differential of the exhaust between both cylinder banks. Messing with the header primary lengths, such as using unequal length headers, will have more impact on sound because you change the timing at which the exhaust pulses from the cylinders meet each other, and whether they collide or not. 180 degree headers would be a prime example of this.

[@Calebt1981]

A V8 sounds great no matter the size. This is amazing!

[@OldCurmudgeon3DP]

Trick dad used to tune the collector length (1/4mi drag race) ... Make a crayon mark down the pipe, go make a pass down the lane, cut the pipe off where the crayon burned off.

[@NOTTApro142]

I bet with the better flowing exhausts it’ll run much better. But if you make multiple of different header diameters you can adjust how much torque, or how much power you want. That’s what they do in Indycar, and almost everything!

[@wesleybarton8854]

Well alrighty then. I think I'm in love. That sounds fantastic! Love the headers and muffler combo. Looks fantastic and sounds even better. Would like to see you put it on your dyno set up and see how it preforms under a load. I am glad it is ok after the oil pump and water pump quit. Looking forward to seeing what you have planned next for this engine.

The return of the machining ASMR king...

[@markspain2219]

That thing rips, could listen to that revving all day!!

[@markspain2219]

Thats awesome!!! What should I do?

[@quinnobi42]

That thing sounds sick! It surprised me how much the mufflers did, I kind of expected that they wouldn't make much difference.

[@0rphros]

Gotta upgrade from the double boggalator and get a 4 barrel for that beast

[@BigMountainCustomRC]

The fact that the "chainsaw" sound is gone makes it so much better. The headers definitely made it sound better. But the proof is in a possible "dyno" pull.

[@captainslow2883]

A rev limiter would be pretty cool to see on a small engine like this

[@TranceFur]

Love the sound of the new exhaust. Before, it sounded like a hot rod someone built in their shed. Now it sounds like a well-engineered machine.

[@MaNNeRz91]

Please make a miniature supercharger for this 😍😍

what, yet another centrifugal charger that cant possibly work?

[@thaphreak]

You zoomed on that belt and heart dropped, "oh fuck" lol. Glad it's fine!

[@0120raptor]

Johnny You advance the timing by moving the rotor arm relative to the inlet cam. I had to do this but it means drilling and tapping a new hole in the rotor arm and grinding a new flat on the cam.I`m setting mine to 25* BTDC. As it comes from Enjomor mine was 5* ATDC which is no use at all.Also changing the hole size in the carb feed won`t do anything. The carbs will never flow enough fuel to warrant equal size holes. Lastly the cam timing and valve clearances need carefully correcting. Both are wrong on mine.

[@lukasboyer3099]

that new exhaust system sounds insane it sounds like you are hearing the engine from inside a car that’s really cool

[@camyota]

The first time ive heard one of these things actually run and sound right!

[@davidreynolds8551]

Love the time and thought that you put into modifying the engine to make it work better. It now sounds a lot better and much more throaty than before. Look forward to see what other modifications you make to get it really humming.

[@aserta]

FYI there's a switch that you can mount on the test board that decouples both wires of the battery so you don't have to fumble with disconnecting it. You can find it in the usual places, like fleabay.

[@asterix3674]

Imagine if you make a 8 to 1 exhaust, that would sound magnificent!

Do one of those crazy 8 into 1 headers. There is a bit of science that needs to be looked at for the collector. It makes a V8 sound insane.

No doubt these engines are made too quickly from china, and you improve them way way more than any possible on a real made engine That's very cool and a great satisfaction for you and us to see.

[@Outlawlife1010]

Sounds like 2 and 6 are running lean. Thats the studder at about 2300rpm and the boggy 2 step after throttle release over 2300. Have a built lt1 that did the same thing. Lil port and polish and new rings fixed her up though. Bad little motor though. Sounds tuff!

[@harshdhiman9720]

Cant wait for the super charger ❤❤

[@nigelbarradell2265]

SOUNDS GREAT WITH THE NEW PIPES

[@GulliJ]

Sound way better after improvement, in my thoughts it need a bit modded exhaust over the new headers. Xpipe and light silencer to not mute it too much but balance a bit the sound and it also appears the rev is way better with new headers so... HP must be better too

[@IzEDraGoN]
