Ok, i've seen people ask questions about the 2090 pipe but i can't find the answer(s) i'm looking for. All the answers 'im finding are 'its better than the 2060'. Why is it??? More runtime with the same/better power band? Same runtime with more lowend/top? If some you guys can tell me from your experience about the pipe compared to the 2060 or even the Nova 9901 would be greatly appreciated.
- More runtime 30 sec or so
- Revs higher
- Overall better feel throughout the powerband
Hope that helps.

Ok, well why did I feel like my engines ran better and were easier to tune with 30%? (not legal anymore, now running 25%)

Increasing nitromethane lowers mileage.

So that XR-B is a buggy engine then? I've always wanted to try an OS.. But the XZ-B is still up there price-wise for me.. (given relative prices of what's available to me..)

Also, isn't it the nitrous in the fuel that is giving the extra punch and torque, not the methanol? Of course, both the nitrous and the methanol have to be in the correct amounts in the fuel mix or else the engine simply won't run, or won't run well if it does start. The nitrous is essentially adding extra oxygen into the fuel and it's the oxygen that allows combustion to occur and the greater the amount of oxygen in the fuel charge will create more power. I can't be bothered to check, but I think that the methanol molecule is made from carbon and hydrogen primarily (with a single oxygen atom thrown into the mix, which doesn't aid combustion. I think it's CH3OH, nitrous being NO. Also, when nitrous is broken down and burned in the fuel charge, the separation of the nitrogen and oxygen atoms is an exothermic reaction, thereby adding even more power to the engine's output.
Consider that some engines use a fuel with a nitrous content of just 5%, therefor it's almost pure methanol being burned and the power/runtime will definitely go way down, compared to a 30% fuel. Of course, I'm not forgetting that there's oil in the fuel as well, but is most likely being kept at the same or similar percentage, regardless of the nitrous %, somewhere in the vicinity of 5-11% oil, depending on the brand of fuel in question.
I hope that makes sense to someone other than me.

Is buyron fuel 25% nitro is good for O.S speed?
I'm asking this because this fuel have only 9% oil .

They are one of the most popular fuel manufacturers worldwide, so I know they do a lot of R&D and would never release a fuel that could possibly damage a persons engine.
Just out of curiosity, have you read anywhere something which states the amount of oil a particular OS Speed engine requires? If so, where did you read it and what engine were they referring to? I'm just interested to read the article/story/whatever as I've not come across anyone saying that any specific engine requires a certain minimum % of oil to safely run the engine without damaging it.
You should be safe using just about any brand-name fuel in your engin. BTW, which OS Speed engine are you using?

I'm not sure that actually makes sense, it seems somewhat illogical. The question was asking about the effects of a higher nitro content in the fuel, so therefor, logic would dictate that if there is more nitrous in the fuel mix, the amount/percentage of methanol would have to be less - the reverse of the situation you describe.
