N20 (300+) - what fuel are you using?
N20 (300+) - what fuel are you using? Just like the topic says.
I have a 12.8:1 compression ratio, will be spraying over 350 eventually, and run C16 in the fuel cell and the stand alone cell on my car. Nitrous system is dual stage (fogger + plate).
-9 plug and timing somewhere around 15 total to start on just my fogger (250 shot).....dont know where it will be when I have the plate on as well.

I would stay with the C16. It is a proven fuel that works great with nitrous and is fairly inexpensive. You could try the C23 but I don't see it making much diffrence other than costing you more money.

Brad, the C16 will work great for the compression that you are running. You could try a higher octane fuel such as the NOS Fuel made by VP, but before you do you should consider two things. One, the small amount of change in octane between the C16 and other fuels with higher ratings probably won't make much (if any) difference in performance or safety. Second, running a fuel with higher octane than what is needed for the compression of your engine can actually lower performance of an engine. The C16 will work great on engines up 13:1 (some one correct me if I'm off on that compression number for C16). Since nitrous doesn't actually increase the compression ratio the C16 would be my suggestion.

ive always read, heard, ect ect that this much spray needs this octain, this much needs this, ect ect, and better safe then sorry.
i knowsome people that have dont the old switch a roo onthe motor fuel at 104 and the stand alone at 117 and boom, just because of dilution.
not even 100% sure what octain c16 is?

VP rates the C16 to 17:1 compression so 12:1 should be cake. It is 117 octane. The C23 is only 2 octane points higher. The VP NO2 fuel (they should really change the name to N2O) is 120 octane and a fair bit lighter than the C16 and C23 (SG of .699 vs. .735 and .713). From what I understand it was designed to be a lighter slower burning fuel to help with the guys that were hurting pistons from running too rich.

Thanks for the correction on the compression limit recommendations of the VP C16. Noyzee, my comments were for brad. I was mainly just explaining that using a very high octane fuel isn't necessarily the best for an engine. Sorry if there was any confusion.
I understand too much octane than needed can take a little power away, but I would always try to run the highest octane that is proper for the combination. If C16 is what works then C16 it is. My point was that if a higher gas will keep it safer then I would not use something less because of the slight difference in cost.
I am not a fuel expert like some of you guys here, so my original statement was kind of generic.

FastBlack - I think all have covered it well here about your setup being good with the C16 in both cell and tank. I know you've been dying to get that thing back to making passes and look forward to the results.
slowredz - How much are you hitting? I've gone the route of pump gas (93) in the main tank and C16 in the fuel cell and would recommend against it on big shots. My opinion is it's living on the edge and unless you're running some specific race that requires pump fuel I'd up the main tank to the good stuff.

Kind of off topis.. but a car that's running around 11.5/1 compression spraying a 150 hit, what would you guru's reccommend for fuel for that? reg. premium in the main tank and good stuff in a standalone, all good stuff, pump gas strait and jet it a lititle rich? Curious, as I"ll be taking the dive over the winter and plan to start off around a 125-150 hit.

It seems like the car is going to make sick power for having a TREX in it on a 110.
