i filled my tank up with Race fuel yesterday and man does is make a difference. My car is running so smooth. I didnt really notcie a performance increase as far as power but the car runs great on it but for 5+ per gallon, I hope it runs good. My favorite part though is the smell after it exits the exhaust. its smells great. It probably sounds weird but, its smells great!

bklynpanman

what brand? also i've been meaning to ask you.. what was that fuel additive again that you used to correct that problem you were having? i'm not having the problem, but would like to get some

blktl1

Honestly I dont remember what brand of race fuel it was cause my buddy had a 50 gallon drum for his supra and let me fill my car up! but the additive is made by Lucas and it comes in a clear bottle and the liquid is yellow. It says that its a fuel additive. Its good to treat your fuels system at least every oil change I think. some one told me not to do it too often because youll ruin you injectors but I dont think every 3k is too much!

If you have cats, make sure the race fuel you are using is unleaded. Most race gas, not all, is leaded and will ruin your cats. Just a FYI.

blktl1

Nah its unleaded. I checked beleive me! LOL, i was waiting for somene to ask that question!

i ran race fuel on my RSXwhen i tracked it. I went through the process of figuring out whats better and whats not when I had that car. beleive it or not the car ran better on the unleaded race fuel than the leaded. I had it dyno tuned for both and data logged those tuning programs on hondata programable computer. they pulle 15 more whp out of the unleaded. weird I thought

Oh good!

I had a daily driver, 03 Cobra with 707 whp and 657 wtq (Kenne Bell Blowzilla at 28psi) which I built to be my daily driver. Some crazy guy in Texas paid me a bunch of money for it so I sold it. I didn't know anything about race fuel until I built this car. The guys who helped me build it at Krazy Koncepts schooled me up on race fuel. I had Horsepower Freaks delivery 55 gallons of C16 to my house once a month for about 10000 miles, until I sold the car. I know what you mean about the smell, it is the best!

Not to get sidetracked, but here is a video of it right after we did the conversion, no tune, low boost, made 603 whp.

One thing I found out with race fuel is you get what you pay for. Not all race fuel is the same and I'm not talking about leaded and unleaded. I had a ton of experience, obviously after many tunes, weeks on the dyno and 10000 miles. Some race fuel isn't stable from the get go, and some loses it's stability with age. The stability affects it's consistancy. C16 is the most stable unleaded money can buy. A lot of "race" fuel is also designed for airplanes, who burn it at above 5000rpm and over 2500 feet in the air. You really have to shoot for the C16 to get the best most stable fuel on the market.

C16 is what I had in My RSX for the most part!!! Good to know that I bought the good s@#@. Its expensive as hell though.

Get the water methanol kit, its just like adding 104 octane when you need it. Too much octane can be bad.

I don't know if you guys have heard of the Woodward Dream Cruise, but man, the whole place gets filled up with that smell, because a lot of the hot rodders and muscle car guys are running race fuel. I don't care if it's bad for my health, it smells so good.

blktl1

I agree with you. It smells like candy to me!~

I am like a fat kid in a candy store with this stuff in my car!!

againstallodds1

The candy smell is usually the detergent in the alcohol (methanol). When I go to the track, I always smell it there, I like it too. My girls cousin runs straight alcohol (methanol) in his notch.

The higher the octane, the less VOLATILE the fuel. Period. More octane means more resistance to the initial burn. So by using a higher octane you actually hurt power production. In order to take advantage of high octane fuels you must have a need for it. High compression ratios, being knock constrained (i.e. turbocharged or supercharged) or running extremely high cylinder pressures. Then there is spark advance or spark timing which can only be dialed in so much before power drops off again.

I've seen this before and I'll see this again, I'm sure. C16 is a leaded race fuel which contains LEAD. Lead is used as an anti-knock additive and in any late model pollution controlled vehicle it would ruin the oxygen sensors and damage the substrate in the catalytic converters.

I had my supercharged and intercooled 4.6L T-Bird dyno tuned by an ex-Ford engineer and it was done with 93 octane Exxon pump gasoline. When I switched to 100 octane UNLEADED race fuel for the track as an insurance policy the car never ran any faster than on 93 octane pump gasoline. In fact, most of the time the car was almost a half mph slower in the 1/4 mile.

Octane does not add power, if you think it does you are wrong. Octane is an organic compound that is added to heptane to decrease it's volatility. What octane does is allows you to max out your combo. If you should decide that your engine can run 10 degrees more spark timing at WOT but you need 110 octane fuel then the engine will respond and make more power. The power does not come directly from octane.

All things being equal, you go as low as you can with the RON # before the engine knocks or pings then you move up a notch. That's were you make the most power. After all what determines power output is how efficiently an engine burns fuel. More octane makes the fuel burn less efficient.

Thanks for the cut and paste guy. You can't edit posts.

Higher octane does not mean it burns slower. I usually run C-14 in my turbo car as long as boost does not have to go higher than 26psi. It burns faster than regular 91 octane and is still less resistant to detonation.

100LL AV gas is my daily driver trim in the car. Compared to regular 91 the car feels slightly lazy before I turn up the boost. But going from 14psi to 19psi more than makes up for the slower burn. Keep in mind I usually shift no higher than 5,500rpm.

If the car does not need octane it won't make it faster. If the car is barely pinging on 91, 100 unleaded will probably add a few hp. But going with C-16 on a NA car with stock compression is just throwing your money away.

Methanol injection is great. I can run about the same boost on methanol and 91 octane as I can on 100LL. Charge air temps actually drop a little below ambient which is saying something on a high boost turbo car. I was running nealy 20% methanol at one time to make up for my injectors being too small. I cranked the boost to 21psi and never did run into detonation. The problem I have with methanol is the transition from no knock to severe knock is abrupt. I don't tune the car to the edge with methanol like I do race gas.

Methanol water injection is great ! On my turbo car it allowed me to run much more agressive timing on pump gas, but having race fuel also made a little more power than 93 oct. Be very careful, C16 is leaded and ive seen guys kill o2 sensors in a few dyno pulls with it. It wont harm the engine itself but it will kill o2 sensors and cats VERY quickly. Alcohol water injection wont do that. You can use straight up -20 windshield washer fluid as it is distilled and has usually around 33-35% methanol in it, the rest is water. The water helps prevent detonation while the methanol adds octane, next best thing to race fuel!

the Lucas Octane Booster that I use makes my motor purr, too. As a matter of fact, I like the
Lucas Fuel Treatment too. It's cheaper but still works.

erick3

isn't that stuff not street legal? i'm looking for some octane boost for tomorrow's little...occassion....

Per Lucas tech phone help: 1.75 oz. fuel cleaner to 1 gallon of fuel = 3 octane increse

check the gen 2 threa on Seafoamed the Ol TL
If you havent dont this yet- it restores clean to everything

untamed

if you wanna run unleaded race gas use the vp103 (streetBlaze) ran this in my boosted rsx and made 539whp.

Why use race fuel if your car is not tuned for it. You are actually losing power because you need more timing advance with the higher octane fuel to make more power.

I hate cars

Not always. When I used to race I found the C-14 to have a faster burn rate than regular gas. I'm not saying you can use leaded race gas in the TL but higher octane (assuming your car can't take advantage of it) doesn't always result in power loss.
