C-12 is ok, but you would be better off with C-14 or C-23.

C-12 only has 108 octane which is going to keep you from detonation with that compression ratio, but C14 has 114 octane which will run better! C-23 is overkill with more than 120 octane, but it would be the best.

Overall... I would say to go with C14!

Can any one tell me what octane fuel to run with 14-1 comp? will C-12 work? Thanks,
Mike
ROCKETT BRAND 114 RACE FUEL:D I saw first Hand on my engine with 10 hours of Dyno Time, Made more power over VP-C14, AND Torco 114, It ran cooler. for the Mud Thats what I use! Some pits are 4 to 5 feet deep and engines can get hot fast, stuck 4 feet deep with 7400 RPM'S trying to get another inch!

It will be ok for the most part... the only thing is sometimes the octane will vary a little and I think it is an unleaded fuel... For the most part you will be perfectly fine!

I can assure you that most of the new Stock Eliminator Cobra Jets are running Rocket Brand Fuel and making plenty of power:D

We run it in our 637 bbc and 16:1 compression. The carbs and intake are extremely clean after 1 season, unlike what we have seen with the VP.
;)

We have been using VP but they have lost there F__- ing minds with the price they CHARGE NOW! Its just the fact of Vp sticking it to you and me I not going to pay there price so the can pay money to those NHRA boys and them not provide any support back to our classes.:mad: I Used C12 FOR THE LAST 8 YEARS in a drag car and from then till now 2010 it is up over 60% And yeah you pay for what you get! Like George Lopez said ( IT'S DA SAME ****!) :D

and after all that Crap that Vp fuel leaves in the carb,tank and fuel pump. I still have not had that problem yet! Nothing against VP, I Used it and would use it again but there prices are outta this world!!!! and you have more of a selection with VP!!! Hands down But I am Supper happy with Rockett Brand!:D

Make dyno pulls on the engine and you will see the difference. Don't care what someone runs in bracket cars.... Dyno tells the tale! The additives in VP are sometimes a pain, but they are the difference maker! Trust me!

Citgo 110 is an average 110 , though it IS leaded . It should work alright for you . Depends on the amount of nitrous and the engine specs as to whether or not it will work . If you have any doubts , you might want to look at Competition Race Fuels 110 ( formerly Torco ) . Its got the highest Motor Octane of any major 110 .

Lots of races are won every weekend by many different brands of race gas . It has a lot more to do with the car combination and the driver than what brand of fuel . But having said that , all race fuel manufacturers agree that the number you should pay attention to when choosing a race gas is the Motor Octane number . Not the only number to pay attention to , but the most important one . Look closely at the Motor Octane numbers for Competition Race Fuels ( formerly Torco ) and you'll notice they are as good , and frequently higher than any other race fuel brand .

How can you tell if you are too rich or lean with race fuel? I know to look at the plugs, but with race fuel the plugs always look grey. Some one had posted a thread about running av gas a while back on here, does any one know where to find it? I thought I remember hearing that you have to add something to it which it lacks? Lead additive? Thanks for any help

The AV Gas that I'm familiar with is 100 Low Lead and all the engines I've run it in likes it just the way it is.....in fact my last boat motor had 11.2:1 comp and I ran a 50/50 mix of 100 low lead and 115 racing fuel to get 105 octane. It loved it!
