I got a gas can full of 110 octane fuel. i was going to throw some in the camaro with my 93 octane. i have 5 gallons of it but dont think i want to put all 5 gallons in it the firat time. what is a safe mix amount to put in? im going to a dyno day saturday, and i wanted to see if/what kind of numbers i can pick up from upping the octane level.

 

Are they going to tune it on the dyno, or just do a power pull?

 

power pull. this is the same company that tuned my car when having the cam installed. i wanted to add some higher octane to kinda debunk whether or not adding higher octane can get you higher hp numbers. and if it does get higher hp, how much more on how many gallons . i was going to do 3 pulls without adding it and then add it and do 3 more, but i dont want to drive around town with 5 gallons of 110 in my trunk.

 

I'd call them and see what their opinion is.

 

Are they going to retune with the higher octane, if not you shouldn't make any more HP unless you are getting detonation of some kind.

Higher octane allows you to pull more timing before getting detonation etc, so if they are just doing dyno pulls it shouldn't matter, if they are going to dyno tune the car with the higher octane... With out a doubt it will pull bigger numbers.

 

Isn't the 110 fuel leaded? I've only seen up to 100 octane unleaded, and if you still have your cats the leaded fuel would not be wise...

 

"Debunk?" There's nothing to debunk. There's no debate. For the most power, you always want to use the lowest octane possible that you can run without experiencing knock retard (KR).

The problem is, there are people who have seen dyno gains from higher octane fuel. They don't realize that is because they were getting timing pulled, due to the fact they were getting detonation.

To sum up.... Higher octane fuel :may: give more HP

It can only do so if you have a problem - "knock retard" - that the high octane fuel will solve. Otherwise, it's useless, and a waste of $

:edit: ^^Sharpe beat me to it^^

 

No, you can get up to 109 unleaded btw.

Google VP 109.

 

Nothing to debunk, just don't do it. Better yet, ask the shop that way you can assure someone who has real tuning experience also agree's.

 

no cats, and the fuel isnt leaded. its unleaded.

 

110 octane rated unleaded fuel? Name of it?

Leaded fuel will also ruin your O2's after a while.

 

i have the brochure at home. ill get it when i go to lunch. they had all types of grades of fuel. from 94 up to 118 or 120 i think.

 

im sure he meant add, not pull. higher octane is a resistance to burning under compression. It will ADD no hp, as stated. Manufacturers recommend fuel octane by how the vehicle was tuned, to control detonation, hence why high perf. cars usually say 93 only, and not 87. Try putting 87 in a stock z06 or something and see what happens.

 

Not sure what the compression is on the Z06 but at 10.5:1 my camaro ran boarderline normal on 87. However, I am not saying to go toss some 87 in lol, only reason mine had 87 in was because someone filled it up and completely forgot to put 93 in (not me). Obviously put 93 in the car if it is recommended but tossing some 87 in a bone stock car is not going to make it go kaboom over night normally. Also the car's will pull timing but you know this, which will lose power if you feel it or not.
