I run Sunoco 110 in my 'bird. Its 13.5:1 N/A. I'm planning to spray a 200-250 shot and when I do will probably go to 116 oct. to be on the safe side.

So if i run C14 in the N/A i will on the safe side ? or that will be too much ?

You should go to their website and read up, but C12 is ~110L. C14 is formulated for high compression N/A (like your combo). C16 is for FI, like my combo. Some folks use C16 for motor + nitrous and some use the C19? or 21?, the nitrous fuel they have.

So plan on C14 for all motor.

If you are running the GM PCM, ignition, cats, etc., you must run unleaded gas. In which case, VP makes a 104 octane unleaded fuel, which would handle c/r of ~13:1.

VP's C12, 14, 16, 25, etc. are leaded fuels.

So the 104 octane unleaded fuel will be good for N/A 13:1 c/r . but how about it if i want to use some nitrose ?

104 octane unleaded fuel will be good for nos.
