I wanna no does race gas mess upp the. Engine because I wanna try it since I'm tuned for it?

[335onjuice]

no just try not to use leaded race gas becuause leaded race fuel will fuck up your cats and 02

Do u have a tune for it? Because if you don't there will be absolutely no gains especially if u are running stock boost levels.

This is OP's 6th thread. At this rate he will have more threads than posts.

Wrong, you will see gains with any up'd octane, you just won't have it maximized because of stock programing. Only use 110 on drag occasions. I use 100 +70/30 meth on the track.

At PS 152 in Queenz that's considered perfect spelling.

[Bimmerfreakz]

I have a jb4 and dci

[Bimmerfreakz]

How about 104 octane that's the one I really wanna try

[Timothy J]

Go ahead. Wont hurt. Just dont get leaded gasoline

“I want get me some of that Sunoco Racing Gas that they use in NASCAR and put it in my daily driver. Then when I am driving down the highway I can stomp the gas pedal and zoom by everyone else.”
If I had a penny for every time I have heard a comment like that over the last 30 years, I would own Key West. What the uneducated speaker does not understand is that high-octane racing fuel in and of itself does not make a car faster, and it does not produce higher horsepower. Octane is simply the ability to resist detonation.

Compression on the other hand is a huge maker of horsepower. A gasoline-powered engine in its normal combustion sequence ignites the fuel by use of a spark plug. A typical gasoline non-turbo charged, non-supercharged passenger car makes about 8:1 to 8.5:1 compression. If you shaved the heads on a factory stock passenger car or cut the deck height on the engine block of a factory stock passenger car effectively raising the compression, you would begin to approach 10:1 or 10.5:1 compression. This would also produce more horsepower.
The downside to raising the compression would be that the engine would detonate or “ping” on regular grade pump gas, which has an octane rating of 87.
Detonation left uncorrected will burn a hole in the top of a piston, cause broken piston ring lands, cause overheating, and ultimately cause engine failure. Detonation is when the compression and heat of the engine ignites the fuel after the normal combustion cycle of the engine has ignited the fuel with the spark plug. This is why supercharged and turbocharged passenger cars require the higher-octane (92 and 93 octane) gasoline available at the local gas stations.
These engines produce higher compression, so these engines require a gasoline that will resist detonation. So, putting 93-octane gasoline in an engine that produces 8:1 compression is simply a waste of money. If the engine is not pinging or detonating on 87-octane pump gasoline, using higher-octane fuel, a fuel with a higher resistance to detonation, will not produce any performance increases.
The engines utilized in the NASCAR Sprint Cup Series produce around 12:1 compression.
These engines would beat themselves to pieces in a handful of laps if they were run on 93-octane gasoline because the fuel would ignite from the high compression and heat after the spark plug had normally ignited the fuel – detonation.
To be able to operate gasoline engines with this much compression requires gasoline fuels of higher octane to prevent detonation. Sunoco provides the NASCAR Sprint Cup Series teams with Sunoco 98-octane unleaded racing gasoline free of charge. This gasoline is not readily available in local gas stations because there is not much demand for it in passenger cars. Even if Sunoco 260 GTX 98-octane racing gasoline was available at every Sunoco gas station in the United States, you would probably pass on filling your passenger car with it as it currently sells around $9.36 per gallon.

good luck, as far as i am concerned u may max.timing but thats about.it, i had a tune for race gas and so absolutely no difference in performance.bcuz.boost wasnt changed

As far as race gas hurting your car? I believe it'll f up the paint if you decide to wash the car with it. Other than that?? Have at it!!!

As it was mentioned, leaded gas will hurt oxygen sensors and cats. Higher octane gas burns slower so you need higher ignition timing to take advantage of it.

I found your past posts;


ok heres the ting take a corner at 35 or 45racing a ricer had a blow out sled into the crub hit 2 fents 2 burshes 4 brick and a trash can but anywho now I have a load cam knock it sounds like but I'm not sure my oil pan may have got pushed back alittle so I dont know if my oil pump got damgaed and itsn't get oil to the top of the cams does anyone have any ideas what else it could be and yea I spanked the little rice hatch back

[Quasimodem]

Why don't you try pouring race gas all over the car and lighting with a match as an experiment?
