Just wondering what you guys are running.I hear alot of the turbo guys are running Q-16 and the nitous guys are C-16 both are leaded so I am assuming its ok to run so a short period at the track. I have a 5.7 with 15-16 psi of boost and lookin to get the most out of it .What would you recomend ?
Leaded will kill cats if you have them. Ive found TT101 for $5.95 a gal in Palatka Fl. Its 100 oct unleaded from Chevron.
Predator 93 Oct. Tune, Radiator Baffle Delete, Intake Reso Delete, LMI True CAI, Mobile 1, EGR Delete, BT Catch Can, Taylor Shorty Wires, and lots of dreams...
I have no cat's so thats not a issue thanks though
I'd talk with your tuner. If your set up can take advantage of race fuel maybe they can adjust timing and/or other paramaters.

Alot of racers are switching to Shell UTR fuels where they were using C16, it is unleaded and has performed very well, you will need to check the tune to make sure everything is good.

I run VP C-16 as it burns much cooler for the KB.

How much of a difference in octane rating fuel would require a new tune? For example my Charger is tuned for 91 octane and I only have 93 octane available, I think a new tune is not necessary. But if I go from 93 to 100 it appers that a new tune is required.
Needing a tune isn't much related to the "octane rating" as it is to the fuels specific gravity(oxygen content). The amount of oxygen in the fuel will determine whether you need a re tune or not. Obviously if the oxygen content is higher, the motor will run leaner. So fueling will need to be adjusted to keep your air/fuel ratio where it needs to be.
If you're looking to use one of the unleaded race fuels. Sunoco 104, vp 109, etc. then you will more than likely be fine without a re tune. It will just run a little safer.
C-16 vs Q-16 I know that Q-16 is oxygenated does one burn hotter then the other? I plan on spraying in the future would one be better for that?
The Q16 is a very good fuel, just a little sensitive to moisture, containers must be kept closed and I would not let it sit around too long.
