hey bro!!! Great point on the gas oil rations to the nitro % of oil comparisons. Yes, people who cant tune kill engines, totally right. And I've only run 30% a couple times, I now stick to 20% only because its cheaper, overall the 20% is adequate on the cost and power levels for me.
I like everyone who's just saying "no you don't" ..a simple answer can make a big difference. That's why I like short videos, they're just on point! Thanks for taking the time to make it.
@@inoahmann7542 The extra oil does NOT make it run hot. But it IS harder on the connecting rod if you're running it very rich. Oil doesn't burn, and more oil takes up more space in the combustion chamber.
Hey man love the channel@ been a long time viewer. I have a question? I have a new engine, it is a GS Racing r21pbx II .21 7 port non-turbo pIug engine. That was a a mouth full, lol but it says it comes with no plug, but the the $125 engine on ebay comes with a os #7 plug and pink and clear fuel tube, also 1 exhaust gasket, and a throttle pully rod end thingy, lol. It has also has a 3 needle carb and a 7 port sleeve. I ordered a pack of 3 of N4 glow plugs on eBay, no brand, but labled N4... well, the damn threads are wrong. Is this normal? Are there various options on threads? Anyway I guess these are useless for me, and I don't want to even give them away if they will be a problem for someone else? Thanks
Hey man the cheap plugs are often poorly made and don't last. The engine you have should do fine on the os 7 or 8 plugs. I know they are a little more expensive but woth it. 💯 as for different plug threads? No. You will only have standard and turbo witch those have different threads but that's it. Hopefully that helps 🍻💯
Always drooling over team Orion wasps I loved when tower hobbies had that engine I woukd view it everyday couldn’t afford it but what a beautiful engine
Of course the engine wears out quicker when it makes more power... Any engine DOES. It's just NOT a dramatic difference that you'd really notice... BUT, you WILL enjoy the extra power... 😁 I run 30% in EVERY engine I ever run. I have many that have 6+ gallons on them. 👌
We did a head to head test probably 15 years ago 2 engines one 20/9 one 30/9 everything else the same and it was so close you wouldn't gane one over the other for engine life. But yes the 30% always runs better
Higher Nitro content cools the engine. Its the oil package that dictates engine longevity depending on tune. You can also get same power from 20, 25, or 30% also.
You don't want to run to cool as it isn't letting the engine get to operating temperature. And if you doing that with ABC or ABN engines it will Prematurely were out the piston and sleeve because it's not allowing it to expand properly.
I run every single engine I have on 30/9 VP nitro. Even my tiny Kyosho GS11...which is in a nitro blizzard with practically no airflow. Every single engine still drips unburnt oil, which means there is plenty for lubrication. Every single engine is tuned to run a full tank, during the summer, and stay under safe spec temperature. High nitro actually provides more mechanical cooling from the evaporative qualities of the ethanol itself, though the "boom" is more intense and may generate more heat and stress in opposition. High nitro results in a nice easy combustion, giving you a huge tuning window to go richer. I was burning up my old engines on 20/15 oil trash, because it had to be sooo leaned out to even run right.
@@thebug4046 Nice brother! Pretty cool you still keep up on a 4 year old video, too lol. Seriously, I run a 23 year old .21bb with 30/9. I have several original XTM 24.7's that I could not tune for the life of me. Then one day, someone said "uhh that blue traxxas trash is impossible to tune with.." 30/9 fixed every engine issue I ever had, no joke!
@@inawrocki207 Yeah I'm usually pretty good at keeping up on comments or at least I try to and top fuel is absolutely garbage 18% oil way too much that's fine for airplanes but not in land engines. 💯
BTW thanks for the advice about the os 3 plug! I got one and it's lasted me about 2 tanks so far. Hope it will make it through my next tank. I'll buy some backups too, and the traxxas fuel and traxxas glow plugs are officially crap.😎 eventually ill probably do an engine swap, once the 3.3 gives LOL
It's not the plugs fault if it's only lasting 2 or 3 tanks that's from tuning it too lean all the time and you're eating the plugs if you're good at tuning and know what you're doing a plug should last you a few gallons. Keep in mind the OS 6# 7# 8# Are short plugs not designed for use in Traxxas engines if that's what you're doing it will make it not run or tune properly. If you have a Traxxas you need OS LC3 OR LC4 plugs Nothing else. All other os plugs are incorrect for most engines
@@thebug4046 Yeah that's the one I'm using. I'm just going off of so far. When I tuned it to "factory settings" with the low speed needle flush, and the high speed four full turns out, it was running incredibly lean. I ended up going through a lot of glow plugs during that time and I richened it to where it accelerates, shifts, smokes perfectly. But the traxxas glow plugs continued to burn out. I'm starting to wonder If the carb is faulty or gummed, because I have the low speed needle way out from flush, and the high speed needle very rich too, with no air in the lines.
@@arturos.l.2248 That also depends on your altitude factory settings might really not mean all that much depending on where you live and the factory settings are often for the original fuel being top fuel if it's a traxas engine so if you use something else the factory settings aren't gonna be completely correct just tune a rich and start from there
I always prefer 30%. The engine runs cooler, idles better, is more crisp, and has some more punch. Some engines do need an extra shim or a colder plug but most don’t, but what seems to be the main reason for that is most European manufacturers get the head clearance as low as possible for 16% or 20%, so when you go run 30% with an ultra hot plug, the tuning window gets super small and the engine becomes very finicky. I’d stick with the same heat range glow plug and add a 0.2mm shim. From my experience, that 0.2mm increase makes the engine run much smoother and tune easier
I have tried coulder glow plugs with a lower nitro % fuel and found it made tune even worse! a hotter plugs seem better as they Allow for a wider tuning spectrum
@@thebug4046 the colder glow plugs don’t burn fuel as efficiently so the engine needs to be tuned leaner so not load up, but cold plugs are significantly more durable than hot plugs. That’s why on-road engines use them
lrp suggest no higher than 36% nitro in the zr .32x 4 spec. i am running Byrons gen 2 30%nitro 11% oil works awesome ..traxxas top fuel is garbage and at 20% nitro and 16% oil it just loads up and weeps way too much as well as making your engine less tunable ..great video keep the content coming...
You can't really buy anything more than 33% at a store And lots it's for Drag Racing are custom made And as far as top fuel when it was being imported here to Canada and they had to specify oil content on the packaging which was 18% oil and 20% nitro and 33% nitro and 20% oil
To be honest you could buy 5 different brands of fuel with the same oil and nitro %%% and you wouldn't be able to tell much of any difference between them. Most companies are running the same blends of castor and synthetic just different colors for the most part. I tested that many years ago and the only ones that were different from the rest was byrons fuel since the oil used was much different then other companies or certain all synthetic fuels witch are usually lower oil around 8% nowadays. At the end of the day pick a brand tune it and send it! 🍻🤘🏻💯👌🏻
Thank you sir!! I literally everyone I have any sort of question I'll look to the bad bug for all my nitro questions!!!! Thanks for your contributions to the hobby 👍
Good Video. I do have a question. If you cant buy fuel with a low oil content in your area. What if possible can you add to the fuel to dilute the oil content down? Is that even possible? Thanks.
As most of us don't do read the manual for your engine. It will tell you what to do with the engine, depending on the nitro content like he said, some recommend shims or removing shims at 30% others do not, but the manual will tell you the manufactures recommendation For the nitro content you want to run it's that simple read the manual
They only engine I've had issues with when running 30% is the Nova P5. I could not get it to act right persuading it with my screwdriver, it had to have that additional shim.
Yeah I hear you but at the end of the day it doesn't sound any different than any other small block and why go through the process of contaminating a brand new engine I always get asked to fire up all sorts of brand new engines that I get or rebuild but the problem is When fuel costs $60 a gallon you want to use it driving not just running random stuff

When are you going to run the Omega I want to see it run I still got mine new in the box I'm going to put it in the Revo one day.. I have a question the Omega has a shorter crank how do I make it work in a truggy
Properly not any time soon it's getting sent to RB Mods for a few things Someone could have also cut the crankshaft shorter it's quite common You will have to buy an adapter shaft not exactly sure which one you will need
Will the pic omega .21 Carrie my losi eighT 1/8 truggy ,as good as my dynamite .28 ,non big red & will the pinion and clutch bell off the dynamite work on the picco .21 omega
Well here is the problem is that engine is discontinued it is no longer sold sometimes you can find them on eBay they are a pretty ripping engine for sure I think it's a 8p
A little while ago I went and bought fuel from a dude that had a rc shop and I told my engine is a .18 and I told him I run it on 25% and he told me no you are gonna burn the engine and I was like tf you talking about and when I got in the car me and my dad where laughing but I still got nitro fuel
It can but 16% is way to much oil and will be more sensitive tuning and make less power. get the sidewinder pro blend 30% or off road 25% or pro blend 20% from sidewinder.
@@thebug4046 yeah I ordered the wrong type I been wanting to check before I did it. I see the race blend in my local hobby shop that’s 30% 9% sidewinder

Should I try a medium plug again with the %30 will that help ? Any advice would be greatly appreciated thank you .
A medium plug should do just fine with 20 or 30% no need to keep jumping around with different plugs all the time pick what it runs/tunes best with and sick with it

Yeah 30% is a bit more but when tuned right it wakes up nice we can barely get it here or it's like 70 a gallon
