Any suggestions?

Is there any Octane Booster that will raise octane level more than 10 points? 8 points is the highest I've found.

haljensen

Depends on your definition of "points". The small bottles/cans that the auto parts stores carry that advertize 2 full points of Octane increase actually mean they will raise 91.0 Octane to 91.2 Octane.

Torco will really give you 10 Points of Octane increase to over 100 Octane but you have to mix 32 ounces of Torco with 10 gallons of 91.0 Octane to get over 100.0 Octane.

Turbo6TA

You are absolutly correct ... and a 0.2 increase in octane is nothing!

You want to raise your octane rating? ... Buy Race Gas!

FloydSummerOf68

Buy race fuel concentrate....not "octane boosters"

True race fuel concentrate is the only way to get high octane blends. They're usually around ~20 dollars a bottle.

I've been trying to imagine why you are trying to increase your octane level over the 93 pump gas widely available. If you are doing it to reduce a knock / timing retard, or preignition I'd look for the cause of the problem and fix that first.

But, I think you're probably looking to "goose" more power out of your fuel by increasing the octane level. This works slightly, but only if your engine is tuned to take advantage of the increased octane levels, timing advance, more air, etc.

If you want a good, proven fuel based HP booster, try KLOTZ COXOC it's use has been banned by every auto racing sanctioning body I've been involved with... Or, get yourself a gallon of propylene oxide and CAREFULLY mix it with 8 gallons of gasoline, it will increase shaft HP by appx. 8% !

Here, do some reading and you'll know what you need...

BUT BE CAREFUL WITH THIS STUFF IT'S HIGHLY EXPLOSIVE AND CAUSES CANCER !

Buy MS103. It is unleaded, wont screwup yr sesnors, wont run too hot, mix to a reasonable level so no tune is rqrd.

LEAVINU

E85

I recommend KLOTZ - affordable and effectively raises octane and leaves behind NO RESIDUE or build up on the pistons, plugs or O2 sensors.

We can have it dropped shipped anywhere in the US. Specs below.

KLOTZ KL-602 & KL628

Description:

Klotz Octane Booster is a concentrated tetraethyl lead substitute formulated to increase the MON octane rating of gasoline up to 10 numbers. Helps eliminate engine damaging detonation, spark knock, pre-ignition, and pinging from low octane gasoline. Octane Booster modifies the burn speed and flash point of gasoline to create a stable combustion chamber flame front, maximizing performance and power. Stabilizes oxygenated and ethanol enriched gasoline to prevent lean-out conditions. Klotz Octane Booster provides needed upper cylinder lubrication that is missing in unleaded gasoline. Klotz Octane Booster will challenge and outrun the competition in the following ways:

* Raises MON octane rating up to 10 numbers
* Improves throttle response and acceleration
* Prevents pinging and spark knock
* Stabilizes oxygenated and ethanol enriched gasoline
* Absorbs moisture in fuel system
* Preserves gasoline up to 16 months
* Eliminates gum and varnish build-up
* Catalytic converter safe
* O2 sensor safe
* Lead substitute
* Fuel injector cleaner

Instructions:

Compatibility: All gasoline, synthetic lubricants and petroleum oils. Will help blend lubricants and oils with gasoline in extreme temperatures.
Octane Booster: 1 oz. Octane Booster per gallon of gasoline will raise the octane by 2 ½ numbers. For optimal performance match the octane to the engines compression ratio. Use octane index A.K.I. and R+M/2. Octane Booster is effective in inverse ratios to the octane lev
Gasoline stabilizer: Preserves gasoline during storage. Add 1 oz. Octane Booster per gallon of gasoline for 6 to 8 months, or 2 oz. per gallon of gasoline for 12 to 16 months.
Fuel System Cleaner: Add 16 oz. Octane Booster to gas tank treats up to 20 gallons of gasoline.: Protect painted surfaces, wash off immediately with water to prevent damage. Will not harm catalytic converters.

Available part numbers: KL-602 16 oz.; KL-628 gallon; 30 & 55 gallon drum

Got a county airport nearby? Avgas is still reasonable. $5.85 a gal here in NY.

C16 or E85

xylene and toluene are both used for racing fuel and are readily available at hardware stores.

The best thing you can do is buy real racing fuel. Run it pure or mix it. (you dont want to run leaded racing fuel unless you remove or gut the cats though.

BTW you only want to raise to an octane level/range to what your car is tuned to (unless of course you are planning on tuning it for higher octane). Ultimately higher octane fuel releases less energy and creates less horsepower than lower octane fuel.

Its just the fact that the detonation resistance allows for a better tuning setup that makes people believe high octane is so great.

LT1_E85_Corvette

squirt a little E85 into the tank. how is that of a octane booster

haljensen

Notice the "ADSPEAK"? Just what is a "point"? Is it 1/10 of an Octane number? 91.0 to 91.1 Octane? Or 1 full Octane number? 91.0 to 92.0 Octane?

Nobody except Torco gives actual octane numbers, just "points".

Snowwolfe

Interesting thread. Up in Alaska 90 octane is the highest I can find at the pump.
Would like to add something to bring a tank up to 93 just to see if it makes any difference.
Any suggestions?

APSGTO

Yeah, and negate any safety you've added with higher octane by going lean.

hobbesnmina2001

E85 is a great octane booster and you don't have to go lean. My 02 Z06 is stock other CAI and Corsa exaust. Last year my track logs showed the stock injectors hitting 95-100% at the top rpms on 93 octane Sunoco with no KR. My car was low mileage but I put a new fuel filter, added a Race Tronix Hot wire harness and logged 95% IDC with 25-30% ethanol by volume mix. Last week I added a KB BAP and I wanted to use the reostat everyone throws away to control the voltage to lower IDC to a reasonable level.
With 5 gal of E85 KB BAP set at 25% richer (~25% from ~6 volt possible upgrade) my IDC came down to 84% at top end and the delivered torque went up by 31 ft lbs!
My spreadsheet shows 97 octane @ $4.02 per gallon and the little LS6 is loving the corn juice!

DUMAN

prices?

Wilddr805

Ok for Zr1s ;o) ? About how many points or ounces per gallon are ideal for Klotz? Seems a lot of owners like this additive and keeps engine running cleaner and better. I need to get down to RPM motors and do a port pulley tune with this stuff.

DOUG @ ECS

the two "LL"'s after the 100 is for "low lead", that will ruin 02 sensors in time.

croatbob

i use torco n 91 as a safety net even tho its tuned to 91
