How many tanks of C16 do you think you can get away with before messing up your o2?

funny thing i only did dyno tuning and 1 track day and my oem are fine but my aem wideband is toast..

will see soon enough

It wont kill the sensors too quickly, my friend ran C16 in his evo every time he hit the track and his 02's lasted for years.


Now if you have a wide band 02 it might not last as long while running Leaded and if the EGT's get really high the sensor will burn out quickly.

Thanks for the response. I only have OEM anyway so as long as it doesn't mess up my dyno run or whatever.

so you're going to be running C16 on your dyno? then what PSI?? cause i thought you were going for a reletevely low boost for your turbo..

or are you just seeing what it can do on high boost and racegas?

either way, i can't wait for results

low boost.......... When I said that I was referring to pump gas numbers. I don't want to have to run 25 pounds to make a good number on pump if you catch my drift.

Anyway, I still don't plan to run over 25 or 26 on race (might do 104, but just checking my options) because I don't have enough injector to support it. (630 - 660 cc @ 4 bar is a little over 700cc+ flow (I think) so I don't think I can safetly run 30 pounds or any Mike type boost numbers).

P.S. Its not worth running a 35r if you are not going to run at least 22 psi. Anyway, this is at best a month off. The motor is not done yet and I have been asked to do 1K mile break-in.......... ahhhhhhhh

If you run C16 are you going to be really high adv timing? Because with out the high timing even with very high boost levels(30+) then you are just wasting the money of buying C16, at that point just run 110 or 104 octane.

Well the only way for me to advance timing is through lemmi..... I don't think I want to go past mid 20s (25+ under 30 --- High RPM advance)

How timing do you run on 104? --- YOU SHOULD SERIOUSLY BE RUNNING C16. I can't figure out why you don't. Its not like you can't afford it.

I run about 25 degs of timing on 104 or 110 at 32psi. Yes I could or should be running C16 but it is twice as much per gallon then 110. I can always make another file for C16 with way more adv timing and load it in when I feel like running C16 instead of 110.
