Why is everything I'm posting going to tech? I swear I posted this in Chit Chat....Anyways, read below:

I've never ran c16 or any type race fuel to this extent. I plan on using it for my dyno tuning this weekend. My plans are to run a 93 tune for the street with low timing and then doing a race tune with the c16 for max results...

My question is how long will my wideband sensor and other sensors last with the c16? I dont want to replace everytime I run the fuel. I've heard some people on here run race fuel and dont have ill effects and others do.

My exhaust is kooks Headers, no cats, x pipe, and magnapack mufflers.

Leaded race gas will kill the o2's but if you only do it at the track you should be ok for awhile. Have you considered e85? It is 105 octane and costs $3. Before I switched to e85 I my plugs would shit the bed before the o2's but that my just be the shit design of the new plugs.

I have but dont have the funds right now to make the switch...And the closest e85 pump is 45mins away and I drive this car pretty regularly

E85 is the way to go, C16 is around $9/gal last time I checked. Worth the 45 minute drive to fill a 55 gallon drum or something. You could do a 93 tune and an E85 tune.

The problem I have, or had with E85...not sure if anything has changed.

The last time I researched it, it shown that the quality was not very regulated. At least here in PA anyway. There were too many inconsistencies in the octane rating, some stations used more gasoline in the mixture than others and that was just too much to risk.

The two shops closest to me are a sheets convenient store, so I don't trust them.

E85 is the best option if he has the fuel system to support it. GT500 pumps and a dual BAP with 80lb injectors are not enough pump to get him the 700+rwhp he is looking for. E85 requires around 30% more fuel than gasoline to run. So C16 is his best option right now with the system he has.

Now later on down the road if he wants to convert he could. The fuel system cost is more, but the long term cost is less.

Run the c16 on the dyno and the track and nothing else, not all the time. Use the 93 for the street and you should be fine for awhile. Like is sounds, the more run you the c16 the faster you will clog up the o2's and such.

In other platforms (DSMs and turbo Buicks), certain wideband/narrowband 02 sensors have shown to be more or less resistant to lead fouling. In particular, Denso narrowband O2s have always worked great for me with leaded gas in the past with my GMs. I swapped my Mustangs sensors out to a set of Densos in the hopes that they work as well in my Ford.

I am right at 700rwhp with the setup you listed. After the new tune for E85 I data-logged my FPDC, at the track, and it didn't have enough margin for me so I upgraded to the 20V BAP and am comfortable with the setup (FPDC around 75%).

I went back and looked at the build thread and I think he is shooting for 20+ pounds of boost. With that much boost 93 octane is pushing it, one bad tank and boom.

I am not trying to sound negative on this build as it is very close to mine but I still worry about the stock KB inlet at 20+ pounds of boost. You may want to get a couple of different size pulleys and see if you max out around 17 pounds. I am happy to help if I can as I spent a lot of time getting mine to where it is and think I have learned along the way.

I agree with that statment, 20lbs is alot on 93 octane. Will be awesome beast on c16 for sure and will run great, no doubt in my mind. I to would be worried on 20lbs of boost and pump gas. Always thought the limit was around 17-18lbs for some reason to keep it safe.

I run c16, and my wideband lasted till almost the end of the season. I had to replace it in October last year. So I figure I'll be replacing it at about the same time. I replace my sparkplugs a lot more.

I was going to go with a 93 tune around 16-17psi and a race tune around 20psi, but Im just going to keep it at 16-17psi for both. I will just have a more streetable tune with the 93 and then the race tune w/ c16

The first night I ran c16, I killed a rear o2. They had 42,000 miles on them, so they were up there in miles to begin with, but the c16 finished the job. If you want to run a higher octane fuel, without converting to run e85, I would suggest sticking with something unleaded (VP109).

Fact. I had less than 3000 miles on my bosch 02s and 13 gallons of leaded 112 killed them. BTW Wideband still works good so I DUNNO.

Im leaning towards the VP109, but just wanted that extra insurance of the c16. We will see what happens when I get the car running good.

E85 ftw son
One of the younger kids in are group run it and makes awesome power. He stores 55gallons at a time. I just can't see spending 9-11$ a gallon for C16. But i run 109 at the track with no issues on my )2 sensors. 4 years and still they read good

Everyone keeps telling me to go e85, but they are not seeing what I keep saying...The closet station is 45mins away! Im not driving and storing 50+ gallons of fuel at a time.

I will only run race fuel a couple times a year. This car will be street driven most of its life. I will not be at the track every weekend. I just wanted the fuel for the tuning and the occasional track day

If you do go e85, do some research on what is at the pump that has the fuel. While they do use 15% gas in the mixture, there is no mandate for them to use a specific octane, so you might get a batch with 15% sub 87 octane gas.

^ for E85 the guys around here have it tested by are performance shop, out of the 3 years no one has ever gotten a bad batch.

Don't get me wrong, I plan on running E85....there is a station less than a mile away from my tuners shop that has it.
