HIgher octane gas contains nothing to add power...something else is scewing your data.

and u'r only arguement to back up (u'r theory) is "well, the dyno said..." lol

personally, i bet the car was knocking to begin with, and then the race gas freed up those couple hp. probably timing was too high to begin with. since u said u changed nothing between runs except gas.

maybe if u contributed something scientificly based results, i would listen to u'r ideas more.

what more do you want? the engine was not knocking to begin with. A/F's were right on the money and it was making power all the way to the redline. it was running great. end of story.

what do you want me to do? what "scientific data" do you want? you want me to have Bill Nye come in and do a taste test?

im getting ready to dyno my 355 for my blazer. its nothing special, so if an improvement is going to be shown, it will show here.

i like how everybody on this forum will call BS on something untill they see dyno proof, now that you have dyno proof, you call BS and ask for paper information. is nothing good enough for anyone?

u need to go to Wikipedia and look up Octane Ratings. they got their research from the chemist's who made the octane rating system.

if u argue with them, then i guess u'r telling me that u are smarter than the poeple who designed the octane rating system/table.

it doesnt matter what the papers say. the papers say a flowmaster adds X amount of power to our cars but we all know it doesnt add ****....from dyno testing. and my dyno test shows it makes more power. ill do it again when i dyno my 355. ill tune it to run on 93, then add 110 to it and post the dyno graphs.

We really dont need anything from you, I know the guys behind Rockett Brand racing fuel and have had many conversations with him, sat in his classes at PRI, etc.....

He KNOWS what hes talking about, "There is no more BTU content in race gas than pump gas" Its a FACT.

But I am humored that you keep it going thinking it was the higher octane that somehow made power.....Its most just likely bad data.

The problem we have is that your results contradict what years and years of racing and research have proven...

Well i guess they could all be wrong? And your one well written out dyno results are right?

When you get results out of the norm there is usually a reason why, even if you cant see it...

And if you search and search and double/triple check everything and it still comes up the same, then you possibly have a break through...in your cause i dont think it is the latter...

Race fuel or leaded fuel will not damage o2 sensors just by running it. The only time lead will take out an o2 sensor is if you have straight unburnt raw fuel hit a hot o2. When i had my turbo neon i still had stock o2s, wideband sensor and that was with 50,000 miles with always running some sort of race fuel in the tank.

Not really sure how you smell unburnt fuel but you must be running rich as ****.

where did I compare the smell of race fuel to pump gas???

let us know how long the O2s last...or better yet when you times start going to **** cause you are still running damaged sensors cuase that can't be the problem why the car is slowing down...

good luck with the car just stop spreading bullshit on here...cause some noob might make the mistake and actually believe what you are saying is truth...

oh and you might as well go with some oxygenated c16...no reason to half *** it...

Yeah as soon as i took my cats off i noticed the same thing. You get that "raw fuel" smell but its not because its running rich. Leaded fuel will destroy oxygen sensors quickly whether its stock or a wideband sensor.
