Does anyone know where I can get the following fuel ingredients?

- methanol
- nitromethane
- castor oil like Benol Klotz, Castrol M or Shell Advance
- synthetic oil like Techniplate, UCON LB 625, Dumonde

Preferably in KL/PJ. Other locations would also be of interest as it serves for other people's curiousity when reading. Thanks.

Blending your own fuel?

Methanol and castor oil can be bought from medical supply dealers, as for the Klotz techniplate you will have to order it online. Castrol M can also be bought from those Racing Bike specialist shops.
Nitromethane is a controlled item, don't know whether you can get it locally or not, you can try the austrialian website. Maybe they sell it.

What percentages are you planing?

I am off to Penang this Wed and I know the supplier for methanol and all ... will ask them for KL contact, used to blend my own plane fuel last time.

I think a good start is always like nothing less than 15% lube is there is no synthetic. Nitro at about 20% is enough. Question is what is the best blend of castor and synthetic?

That is what most fuel manufacturer didn't put it down(trade secret) As synthetic will burn out faster than natural caster, Natural caster aides in the cooling and will be the remain in the crankcase, so my guess is around 40% syn and 60% caster out of the lub content percentage.
BTW, Initial D you should ask for the ungummed castor, normal caster oil will leaves a shellac like residue in the crankcase.

15% oil? Might as well run diesel in these engines ! That's too much oil. I think it'll become like PowerTrack nitro. Blubbery and sluggish.

Usually, 11 to 12% is enough. If you want to race, then 8% lube is very nice. The guys at the recent 1/8th worlds use 4% lube ! That will give you all the power you want but sacrificing engine longevity.

The rule of thumb is for hot days, you use about 50% equal portion of castor and synthetic. For cold days (hardly ever in our climate), use castor in 30 to 40% in the total lube proportions.

just make sure you have fire extinguisher nearby. I also heard that when mixing fuel you have to really mix it well otherwise the nitro will evaporate fast and your mixture will be incorrect....is this true?

more like moon shining samsu !

Ummm, did not think of that. The idea of making your own fuel is for quality control and also to keep the cost down further ! As much as possible, if the ingredients can be bought locally, the better it is price wise.

Benol would be a better replacement but if Castrol M is the only thing available, then I have no choice... Racing bike specialist shops? Any examples?

Controlled substance? What are their other uses besides for RC fuel?

The problem with combustibles is they cannot be transported easily via courier etc.

Ummm, that would be a variable !

Mix in smaller quantities lah...

One heat, one engine strategy?
The engine will not last more than 2hr using this percentage, the sleeve/piston and bushing will wear out from the lack of lubrication.

InitialD

Yup, more like it. Look at the amount of engines they brought in...

Are you sure he is not selling them there during the race for any sucker who blows their engine?? lelong lelong!!Corally tuned engines

InitialD

Why would Collari want to sell his priced engines and give more power to the competitors at the Worlds?

cheh, strategy, make the engines he sells a bit slower mah, the ones for himself more powerful mah!! Anyway he won the race yeah??!!

The problem with mixing your own fuel here is the humidity factor unlike in europe. As methanol is hygroscopic, absorbs water from the atmosphere, so, it might not be a good enviroment to blend your own fuel unless, it is done in a suana room!


Look for those shop that always races their bike in Shah Alam or Sepang or Go-Karts shops may also have these in stock.


Ever heard of nitro bomb? Is a sort of explosive aiding substance(oxygenator).

Yea, but you can also declare it under lube oil, and pray hard nothing happens during the trip.....

Its like playing TOTO with more variables, so higher chance of your name in the top ten!
