I was curious to know if Race gas, burns out o2 sensors? And if so how would you run the car if you had high compression, and need 100-110 race gas?

 

I have seen race gas kill 02 sensors before, but not all of them. I am not sure what makes it burn some, but not others . . . anyone else know?

 

is there a way to run a chipped ecu, without an o2 sensor then?

 

Only thing i've seen is cars chewing through spark plugs while on c16, a few pulls on the dyno and it was time for another set...never really have seen it happen to an o2 sensor but i guess its possible.

 

Leaded race gas will shorten the life of O2 sensors. I've ran a fjo wide band for 2 seasons with no problem. Aem wide band also all this year and there replacement o2 is very reasonable. Also AEM will warrenty them for 1 year.

 

burned our o2 this weekend at pomona!!

 

Leaded gases are said to shorten the life of an O2 to ~1/100th of the original.

 

is 110 usually leaded? Im not sure, because I haven't looked into any race gas locally yet.

 

Yes the majority of race gas is leaded. Check out http://www.vpracingfuels.com/i...620F6
for info about a lot of common race gas. I've personally used I think 8 different kinds of leaded VP and never run any of their unleaded stuff. I've heard the Motorsport 103 makes good power though. Get ready to pay $10+/gallon for anything other than the typical shelf-stock stuff though.

 

yes it will chew a spark plug up! yes it will shorten the life of the 02 sensor. but I have started running m1o by vp and its unleaded. $5.25 / gallon

 

where are the prices on that site? or do you have to contact?

m1o = motorsport 100e?

 

Life expectancy of wide band sensors on leaded fuel is only around 50 hours...
