Octane booster
 

Alright guys its time to find out. does octane booster work in any way and what experience have you had with it, and if its has worked what brand works the best.
thanx.

What are you thinking that it is supposed to do?

Raising the octane in gasoline does not effect the BTU (power output) of gasoline. It only lets a motor tuned for the higher octane not blow up.

So if you are asking if using any octane boosters give you any more power, then no... it doesn't. It's some dumb tuner old wives tale that people think it makes more power.

Now if you advance the ignition timing, or increase compression (to get more power) to the point when the engine has pre-igniting or is detonating, then an octane booster will help you not blow up your motor.

^what he said.

I once made the mistake of having a car that was tuned to need +94 octane gas. Never again for a street car.....

It's a waste. And a lot of them don't even raise the octane, they just clean the combustion chamber of carbon build-up to bring the compression ratio back to stock.

Octane boosters work well......

At liberating your money from your pocket

That's about it....................

I wouldn't use it unless your runnin nitrous

You be better off using lower octane fuel and running your engine right before it pings(MIAC). Say 87 or 89

Flame away!:batman:

I wouldn't use it unless you're running nitrous and call it naaaaaws!

Dis be true.

what about if you cant find any premium? cuz i know about a month or two ago i couldnt find it anywhere. and used octane booster for about 3 tanks.

That's what the knock sensor is there for. Can't find premium? Where do you live???

lol it was awhile ago. when gas got really expensive. i live in chapel hill durham hillsborough area in NC.

They really ran out of premium? Or you didn't want to pay for premium and used octane booster instead?

Either way if you use a gasoline that doesn't have enough octane in it, the knock sensor will retard the timing and engine power slightly to compensate. However if you use lower than 86 octane; the PCM with the knock sensor may not be able to retard the timing enough to compensate for that too low of a grade of octane.

Even with nitrous and F/I fuel higher than 93 octane is unnecessary with the right tuning.

no they really didnt have premium. every gas station was out. which pissed me off alot. because i didnt know when i would be able to put it back in. and i dont like putting regular in my tank.

There's no way it's cheaper to use.....

Don't mis-read the labels - they claim a bottle added to ten gallons will raise the rating by two 'octane points' - they don't explain an octane point is POINT ONE of an octane 'rating'! So your 89 octane becomes 89.2!

You'd go broke trying to duplicate premium gas.

S

yeah but i figured it was a quick fix for a little. i mean it's not like i still do it. ever. honestly i felt like i was betraying my car by pouring that shit in there. and then filling her up with regular. i hated it. but i went to about ten gas stations before giving up.

waste of money... might as well just put higher octane gasoline

O by the way I'm finishing the naaaws;) this weekend I'm going to use a booster too what is a good one?

lol....I hope you're joking. Just poor a gallon of ethanol in there. No don't do this...only kidding.

Does not work according to this

According to me, I tried it and felt nothing.

Toluene..............

to get more power outa the octane booster

u need to have lots of nawwwz and electricsupercharger.

I spent a couple of days looking octane boosters up and found several independant test results showing that most dont do what they claim and the ones that do what they claim are still a waste of money.

The big problem is that the chemical many use to raise the octane rating is raising it but it causes the combustion to run hotter so you are effectivly doing nothing or in many cases making the situation worse.

Also, the knock sensor on the RX8 is basicly worthless, so nobody should be trusting it to save your motor.

If you can't find anything but regular unleaded then I you should not run WOT. plus/middle grade usually works fine on our cars as long as you have not tunned it to run leaner (AP or racing beat tune) I hear the RB tune is the most aggressive on the timing, so be very carefull running anything but supreme.

Back to the octane boosters, some are effective at raising the octane rating but I would not trust it and its too expensive.

If you google octane booster you will find tons of threads on how to make it yourself in more potent quantities. But I don't know if I would trust it. Like Highway8 said, it may burn hotter in the combustion chamber which could cause some major issues.
