Well going based on my VR6 which wants only 91 octane or better in it. The onlything that would happen is that you would get spark knock and your gas mileage would suffer a bit. There wouldn't be any long term damage to the motor, it just wouldn't run the best. The motor was tuned to run on higher octane gas so that's what you should continue to run in it. When i bought my 01 GTI i put 87 in it and all it did was give me spark knock and didnt have as much power as it does running on 91+. Only reason i put 87 in it was i didnt see the sticker on the inside of the gas lid till it was full. After that its been nothing but higher octane fuel.
20t
30 * 20t * 10 = 6000t
y(t) = 3.5 - 3.5*e1-20t Then dy/dt = -3.5*e1-20t*(-20) = 70*e1-20t
No because 16s+20t when factored is 4(4s+5t)
Yes The 20T motor is slower than the 15T motor with The 19T pinion
h=20t-5t2+1
No, a 40t is bigger. 40t vs 20t refers to the number of teeth(that engages with the chain) that each wheel has at its circumference. The tooth size is fixed for all bikes that use the same chain spacing, so a 40t chainwheel will have double the circumference of a 20t wheel.
20t
20 gallons is approximately 75.702 litres.
If you mean 20t^2 -12t then it is 4t(5t -3) when factored
40 THOUSAND lbs. It takes 2 Thousand LBS. to make a ton.
"Needed" isn't a suitable word. Any tooth count will work, and only rider experience can say which will work best for him/her. 20T is fairly small, so I'd recommend a small freewheel too, to get any kind of speed out of the bike.
