Which Race Fuel?

[RobsIron]

Just wanted some input on which Race Fuel to use.

I've been running Sunoco 110 and want to step up.

I know VP C16 is one of the best but its pretty scarce here in Jax.

Anybody use the Citgo Rocket Fuel 114? It use to be known as Unical 114. Thanks.

Unocal 114 is only 110 motor octane. In my early buick racing I took more head gaskets out with that stuff than anything else.Of course i thought it was 114 the whole time. If tuned for the appropriate fuel it should be fine.If you can get Unocal 118 thats 114 motor.

But the best plain and simply is VP 16. Unfortunately u said it was hard to find and it will get harder VP raised fuel prices and freight charges.My local guy is thinking of dropping the all together.I wouldnt trust any race gas from Citgo.

I use Sunoco 118 (Red). I believe it is 116 motor. I have access to all types of fuel. The distributor that I get the fuel from, who also carries both (Sunoco and VP) says this:

If you rebuild your engine every year, then use VP. VP is alcohol based and is "drier"
Sunoco is petroleum based and if you don't like re-building, use the Maximal.

His next statement was "The choice is your, so which one do you want?"

Hey Billy (gnxtc2), I'm also in North Jersey about 45 miles west of you. Are you allowed to divulge your distributor? It'd be nice if I could know somewhere in North Jersey where I could get Sunoco 118 (besides the track). Does your distributor sell in small quantities?

Thanks
Mike

I have ben having great sucess with Track Tek 118. I wanted to get another barrel of C16 but I couldn't find any. I bought a barrel of the TT 118 for about 1/2 the price and have been very pleased with it.

Track Tek Info

VP info

The specific gravity of the TT118 is less than C16 but it is 1 point lower on motor octane

The Marathon station down the street from sells 110 octane unleaded. Anyone try this stuff out?

 

[RobsIron]

Thanks Louie...Good Info.

gnxtc2, Wow I didn't know VP was Alchohol based.

Doug I haven't heard of Track Tek. I'll check around.


One of the guys I talked to at the race shop said Nascar changed from Sunoco to the Citgo RF this year. Anybody Know if that is true?

How about Cam2 or any other Flavors?

The Track Tek fuel was formerly sold under the Phillips Petroleum brand. They changed the name, but the fuel stayed the same. My friends and I have been using the 114 for years. It's good stuff and much cheaper than Sunoco and VP. I would put it up against either of them in a heartbeat. I've ran 35 psi in my combo on year old TT 114 with no knock. This year, a wastegate malfunction caused me to make a pass at an estimated 40 psi. The fuel was fresh TT114, and DS showed just a few frames of knock (less than 2 degrees) in 3rd.

I used the same TT-118 fuel that Doug was using last weekend. I forgot to attach the vac line to my AFPR, and made a 25 psi blast down the track with with 27 degrees of timing. I got 1.2 degrees of knock retard at 110 mph and the scan master showed o2 readings in the 500's. Once I re attached the vac line, I had no problem running 27psi and 27 degrees of timing with no knock in high gear. Not bad for gas that costs 4.20 a gallon

 

[RobsIron]

I found out today that the Rocket Fuel 114 has 110 motor octane is produced by some fellas from Union 76 not Citgo.
Alot of roundy round guys are using it with good results.

This guy had good things to say about Track Tek and said the Rocket Fuel is Comparable.

 

[Taffy]

VP is rediculously high priced.

I like to use regular Unocal 110, since it is about 4.50/gal.

No problems with the 110 on a LOT of cars and a LOT of nitrous (not the TR).

VP c-16 (117 motor octane) @ 8.65 per gallon...gotta pay to play the game guys

Actually I'm running faster on the TT118, I've payed and played in the form of 110 gallons of C16. In a pinch I bought a barrel of TT118 for 1/2 the price and ran just as good or faster with no ill effects thus far.

[stangbanger]

I agree with Taffy and Doug. The "big name" fuels are way out of line on price. I would put TT up against any of them, performance wise.

Oh....Don.....I noticed the "10 second stock motor" line in your sig. Yes, it can be done. Look at my sig.

anything from vp is good. i usually run their c12 if i'm not going over 20#. its $6.50 a gallon insted of $8.35 for c16. its definatly not as good, i still get small ammounts of knock with 18# 24* and 50 hp of n02. c16 i can run whatever i want with no knock.

shoco is ok, i can get by with quite a bit on their 110, their110 is really something like 96-98 motor octane. if you get the vp 110 it is 110, and costs about the same. if you go down the the 98 vp stuff, i run significantly faster with the vp, it has some other stuff in it that makes it burn better.

i started using their csp recently. i think its 104 octane, made for high boost road racing cars (specifically supras and rx-7's) not bad stuff, and its unleded so 02's last. close to c12 in price.

stangbanger,

How much boost are you running, launch and big end, to get that sort of performance from an unopened motor?

 

[TylerDurden]

I cant explain why, but c16 is suppose to be great for our cars (its my gas of choice though i pay 9 a gallon for it) because of its high octane and higher than ave .73X specific gravity. The TT118 i believe sits at .700, so how does that effect its performance in our cars?

GNTTYPE.ORG

SPECIFIC GRAVITY (SG): (a) This is the weight of fuel compared to water, water being 1.00. If race fuel were .750 (SG) it would weigh and the weight of water. (b) The less dense the fuel (lower specific gravity) the higher the BTU content, and the better the stability of the fuel at higher RPMâs. (c) The lower the specific gravity of the fuel, the more crucial the jetting becomes, and the easier it becomes to run lean. (d) The combustion speed is determined primarily by the (density) of the fuel mixture. (e) The higher the specific gravity, the cooler the fuel charges.

I am not sure whats meant by lower SG=more stability at higher rmps, when it says lower SG=easier to run lean and higher SG=cooler fuel charges (which is what we all want right?)

 

[strikeeagle]

Even better (for about $20 a gallon):

VP Import
Maximum power and torque in small displacement, high RPM, all motor, turbocharged or nitrous sport compact applications. Makes 5% more power than C16 and similar nonoxygenated fuels. Works well under high temperatures due to mechanical heat.

• Color: Clear
• Motor Octane: 120+
• Specific Gravity: .744 at 60° F

 

[TylerDurden]

yeah i had read about import, and as good as it is, its not worthing paying "ricer parts" prices for it

i have an inport vendor down here that sells PTE turbo and other parts exclusively, so why does the SC-44 cost over 1000? its the same internals as a TE-44, just a 4 bolt exh housing, which seems to be norm for all import turbo's...we seem to be the bastards in that regard.. but i digress......

but back to race gas fuel comments.........

 

[denn454]

if your into spending money go c43 (c34, don't remember) its some super violitle fuel that handles very high boost and makes rediculious power. it cant' be used at high altitudes because it will evoporate about as fast as you can pour it into the tank. i asked about it, the place around here wants $75 a gallon to bring it in. and you'll loose about 1/3 of it pouring it in the tank.
