Re: %Fuel

There is no real proof that running a higher nitro content is good/bad/better/worse blah blah blah.
I'm going off from what other ppl have done, the results they had from it, and the results I am seeing from it. 40% nitro in my opinion is far superior to 10% - 20%. I am running Blue Thunder 40% with 6 oz-added castor oil. I will NOT go back to 20%. It's a night and day difference between 20% & 40%. Cooler temps, better idle, and stronger motor. The greatest advantage of upping the nitro is you can runner a richer setting, which will bring the temps back down while getting added performance. I am running 2 1/2 - 3 turns out on the main needle. I am getting more power now than when I ran the truck lean on the 20%. I have not used a temp gun to prove this, but I can touch the stock head now and it won't burn me like it would when i was running 20% lean.
The added castor oil is a vast improvement also. Since there no rings in these engines, the fuel/oil mixture gives you the seal also in the combustion chamber along with the tapered bore.
Hope this helps some.

Re: %Fuel

first i have an ole traxxus nitro hawk with a .12, secondly i have a nitro rustler with a .15. I switch my gas from 10 to 15%. I heard the same hoopla as everyone else, anything more will fry your motor and i'm just skeptical. NavyDood, how much fuel do you mix with 6oz. of castor oil, 1qt, a gallon??? How much of the 40% mix have you ran through your motor? Marc

Re: %Fuel

DOH sorry all.

I have a T-Maxx with the stock motor. I know of ppl getting up to 15 gallons of 40% thru their engines with the added castor.

Re: %Fuel

Hey navydood, did you and do you reccommend breaking in your motors with the 40%, and you still didn't tell me how much fuel you mix with 6oz. of castor oil. Thanks Marc

Re: %Fuel

what? why do you guys mix in castor?
i just buy my 15% and dump er in. methinks this is why you can run 40%

Re: %Fuel

The oil content should be minimum 16% for car engines. 18% is preferred by most manufacturers.

Blue Thunder is only around 12%. By adding 6 oz. of Castor oil "To a new full gallon of fuel" that brings the oil content up to around 18%.

Castor oil is one of the main ingredients in the Nitro fuels for lubrication. I buy the castor from wal-mart in the laxative section. (No I'm not kidding) That is all the stuff is.

I didn't break my engine in using the 40% with added castor. I used Traxxas' 20% because that is all that the hobby shop had at the time. As soon as they got the 40% in, that is when I switched.
