92 Octane for Nitrous?

I'm a daily driver and I am not going to use nitrous at any certain time. Do you have to use 92 octane with a wet system? Whats the disadvantages other than speed? I read it can cause detonation in the cylinder in the articles section. I'll probably be using 50 or 75 shot. If you have to use 92 octane then I'll probably not be getting NOS because I don't pay for gas, my parents do. (Im spoiled.)

Thanks

Re: 92 Octane for Nitrous?

You don't "have" to, however in order to run nitrous on less you will have to pull timing to avoid detonation which will in turn decrease your power. Also, the lower the octane, the better the chance of detonation even with lower timing.

You don't want to mess around with nitrous and try to "make it work". Nitrous is something that requires a good tune and good gas or else you can efficiently take apart your motor. It's not something to try and skimp on. It's one of those "Do it right, or don't do it at all" kind of things.

mixing a little 110 octane with your 92 tends to help

He's wanting to run sub-92 octane.

To add to my previous post, if you get a wet kit you could run 87 octane in your car as long as you had a higher octane in your secondary fuel system...like 110. A dry kit, I would not recommend running anything but premium.

Re: 92 Octane for Nitrous?

i would recommend running above 92 ocatane with nitrous period. if u think about it this way. average price difference in 87 to 93 octane is 20 cents a gallon.. so average fill up is 12.5 gallons. approx. $2.50 extra.. it's worth the extra couple of bucks.

if this car is your DD i recommend stickin to bolt-ons.
