Don't forget your o2 sensors will go bad as well.

after how long though....i know its not an exact science but is it like 5 passes or like a few months?

It's not guaranteed that they will go bad. Some people have run race gas for a long time and never had issues.

Don't forget also that there is such a thing as 110 octane unleaded fuel floating around as well.

if you car has an aem, then the stock 02 sensor aren't being used anyway most likely, i removed mine... plenty of people run race gas all the time with there widebands and have no issues :dunno:

O2 Sensors are like 70 bucks, it's not that big a deal to replace them if they go bad. I don't ever worry about it, and I have a wideband.

for the amount of race gas your looking to run, i doubt youd ever have a problem, and look on the bright side...If the cats go bad, get rid of em :)

I have already spent a lot more on "steady" race gas than a stock O2 sensor costs...I wouldn't be too worried if I were you. Just part of the TCO (total cost of ownership) if you like high boost! :)

I got a whole summer out of my O2 sensor runing CAM2 115 leaded, probably 20 tanks of gas, before I had to get a new one.



I wouldn't wory about it.


Hope this helps,

Bob

Que?

The MkIV sensors are much more than that and mine above the DP was a royal pain to get to.
It's probably easier on a single, but it's misery on the stockers!

Does race gas Truly Make a Difference? Like if I dynoed my car BPU+ at 18 psi on 91 Pump or 100 Oct Race gas would the numbers really be a huge difference?

18 psi on 91 OCT probably = kaboom.
Answer = yes.

Keep doing that on 91 octane and see how long it lasts.

There's a reason why the general rule of thumb for boosting on 91 octane gas is usually no more than 1 bar, just to be safe. But hey, if you feel like its fine, keep doing it.
