RE: TopFuel ? 90% Nitro Fuel ? Anybody uses that ?
Out of curiousity where are you sourcing your nitro TF (Top Fuel) from which has this 10% methanol added to it and how much it costs and shipping cost if you know them I think in the USA they are reluctant to sell pure nitro any more in case the gooks might make bombs with it and so it is sold cut down with some methanol .Also there is a small but extrremly small risk that 99.99% nitro can become shock sensitive and the risk increases with age with age so they put the dye in it to show when that risk becomes more possible.The adding of 1% methanol reduces that risk to be shock sensitive to neglible.The adding of 10% methanol probably makes the use of the nitro methane for other uses much more difficult than drag racers where rules dictate max ~85% nitro . Certianly if the prices of TF (Top Fuel) are good for the nitro when you factor in the off the shelf prices in the LHS methanol is typically €12 a gallon imp (4.55 liters or 1.2 gal USA) and nitro for me often costs ~ €140 per gallon imp and EDL costs ~ € €120 per gallon imp then buying the nitro TF (Top Fuel) that way with 10% methanol mixed in might work out cheaper for me . What shipping rates are you working with as nitro and methanol are often HAZMAT rates ??? balasaeater

I ant no expert on smoke but it tends to work better they say with gasoline engines .This is becuase the gasoline burns much hotter than glow fuels so the smoke systems tend to work best with hotter burning fuels Balsaeater

RE: How to "Make" own fuel
[quote]ORIGINAL: downunder Well here's a bit more to add to the arsenal, nope, not a cut and paste this time :) but just something I've learned. Infernal combustion engines get more efficient the higher the compression is but of course this is limited by what the fuel can handle. Nitro is terrible at handling compression so you give away efficiency but gain back by burning a lot of what's really not a good fuel in itself. Most engines have a compression of around 9-10:1 which is fine for relatively high levels of nitro (~20% area?) but methanol can handle around 17:1 compression. I experimented with an Enya 60X by running it on 80/20 fuel and incrementally raising it's compression. At 13.5:1 it'd gained a little over an extra 20% HP which probably put it somewhere around what it would get using lots of nitro. I'm certain I could have gone even further if I'd also experimented with colder plugs which would have retarded the ignition point so allowing an even higher compression to advance the ignition point again. Given what I found, I convinced my son to use the same fuel in his car but with the compression also raised to the same level. It performed exactly the same as identical cars/engines using 25% nitro other than he could race for 8 minutes per tank compared to 6 minutes for the others. Quite handy when they have to make pit stops :). The difficult part about doing this though is you need some accurate measuring equipment and a lathe because taking out a few shims doesn't come anywhere near doing enough. [/quote] Unfortunaly the glow plug isnt so good for controling when the fuel ignites .I think 17:1 comprssion ratios or even s high as 22:1 are rumoured with methanol are sopposed to be possible with spark ignition methanol engines.Glow plugs wont go so high as the predetonation issues will get them.Methanol fuel neat with no nitro can be interesting for high compression for those with the tools to do it with some engines How difficult was the tuning as its reputed it gets more tricky to tune as the CR goes up Blasaeater

RE: Fuel for Savage XL K5.9cc Truck
Hi I m more from the model planes but I have helped car guys out First thing is the new engines can be dogs to use tune etc until they run in Realy its better to use running in fuel higher in oil and lowwer in nitro methane These engines will run OK on 80% methnol and 20% castor but you wont get the fastest speeds or fastestest acelerations Adding nitro methane will boost top speeds posssibly 5 to 20% depending on the model.However the accelertion will be greatly improved especialy the low end with higher nitro content which is good in small circuits with lots of bends when racing another similar car If however your just beating up and down a straight track for fun then high nitro content isnt probably worth the extra cost or issues These engines will run well on all castor fuels or all synthentic fuels or combinations of the two oils .For maxumum speeds then its probably going to be either 100% sysnthetic or a mix of something like 70% synthetic or 30% Castor The total oil content can go from 8% up to 20% depending on factors .Racing guys will often try to use the minimimum and that might be 8% synthethic .General modelers will probably opt to do 15% with some sort of synthetic Castor mix like 70-30.Guys who want more economic fuel or want longer life for the engines and are not so worried for the messy quality of Castor might opt to use 15 to 20% all Castor oil Nitro methane is best thought of as nearly liquid air as apposed to its fuel.So ~30% nitro methane from the engine points of view really mens its 70% fuel and 30% air (in real life it does burn a bit but but its full for nitrogen which expands with heat and oxyegen which burns with methanol).This mean that often 30% nitro fuel will double the fuel consumption eg your tank runs out twice as quick but you might gian a 20% power boost.However the 30%nitro fuel might cost twice as much as the non nitro fuel so in effect your rinning costs could quadruple So for economic most users opt to use 5 or 10% nitro fuels as that often gets them 95% of the cars abilties If the fuel is a zero nitro or low nitro like 5% it will be better often to have a hotter plug.If the fuel is a high nitro then its often better to get cooler plug.You know if your plug is too hot if its life is too short .You know if your plug is too cool and it wont tick over for too long and stops after a 30 seconds or quits when you go to pull off The fuel the airplane guys use will often do the job for car fun running around but might not give you best top speeds Model airplanes due to the heavy loads from props often have to use very high oil contents typicaly ~17 % However some home brew fuels for model planes on the bigger engines are down to ~10% but off the shelf stuff from the LHS is rarely below 15% I would put through the engine a low nitro ~5% fuel with high oil content of 15% to 20% of any type with castor in it eitier all castor or part Castor for the running in say two liters Expect the engine not to want to tick over so great and not be able to go so fast as it is still tight when its running in .I would keep the body off for extra cooling if its hot weather and to make it easy to restart if the engine stops with half the fuel still in the tank whatever After that if your happy with the fuel then you can stay with that fuel .If you want max power you can look to go to a 8 to 10% synthetic mix with a ~25% by volume nitro fuel(30 % nitro in the USA often mean 30% by weight which is something like ~25% by volume ) Rough rule if your importing fuel from say Turkey which supplies model fuels or if the main fuel supplier is in Tehran whatever chances are its made to european specs and nitro is mixxed to volume .So ~20% nitro european would be ball park ~25% USA equivalent and ~16% european would be ~20% USA and so forth Some model car fuel racing regulations for racing fuels specify either max of 16% or 25% nitro fuels allowed Nitromethane is often difficult to get so although its reputidly more bad for the cancer producing fumes or issues some guys replace nitromethane with nitro ethane which is about ~70% the power of nitromethane . But often nitro ethane is much cheaper and more easy to get hold of outside main land europe .It often in mainland europe that nitro ethane is not allowed to be used or sold anymore due to it reputed cancer producing issues If you do use nitro ethane read up on the risks and the instructions and dont breathe in the fumes However most model fuels in the 1960s era had nitro ethane in it and there are still many of those modelers still alive and kicking For methanol its better to aim for 99.9% quality. Sometimes in real hot climates for extra engine cooling we add water to the fuel maybe as much as a few % as it help take the heat away . But that is specialist stuff for the experts . Generaly any water in the fuel makes the engine often a dog to start and tune properly. Methanol fuel will soak up water from the air real quick if you leave the cap off .If you look at the fuel in the bright sun and you see stringy things in it thats water content where the water doesn't quite mix with the fuel .If the fuel has got this quality shaking it a lot before refueling will mix the fuel better and reduce the risk for running issues . It often seems to be the case that methanol that is classed as 99.5% seems to be more dodgy manufactureing or something and makes life hell to sort out for modelers as to what is the issue.Stories bound of guys who buy a 200 liter drum of 99.5% and it requires the whole drum of the fuel has to be fine filtered to remove the BBS and SBS ( big bits of s*** and the small bits of s*** )which seem to float throughout the stuff. That 0.5% seems to be not just water but anything else that was in the factory where it was made . THis methanol is probably meant for the less critical industry uses like chemicals for cleaning where the factory would clean the methanol before mixxing with other chemmicls . For whatever reason this happens with 99.5% methanol I never heard of any problems if the methanol is highest quality 99.9% Hope that helps somewhat balsaeter

RE: *** CLUB SUPER TIGRE ***
I dont find the cost to use methanol in my 26cc MVVS and 30cc Saito too big an issue > I get the methanol by the gallon and the EDL synthetic by the half gallon and the nitro by the half gallon.Mix is 10% oil 5% nitro and fuel consumtion is on mid gas is about 1 onz per minute or 2 onz per minute WOT. The difference is WOT with the glow engine is easily 25% more than most gassers of same CC Based on that I would probably opt soon to get 200Liters of methanol and chase up a few bigger second hand Supertigers like 30cc 35cc and 60CC or failing that get other makes of glow motors of similar power and dimensions The methanol fuel consumption is about 1/3 more than a gasser and as my local prices for Methanol in 200L are about 50% more than gas I estimate it costs twice the price than running a gasser,However unless I drop my electrics which I fly a lot at the same time the few flight every weekend about one gallon of glow a weekend don't make it worth it for me to switch over to gassers full time.If however I was doing three gallon s a week of glow fuel then getting a gasser might be more interesting to keep costs down Certianly more than 60cc I would change to gassers Balaseater
