octane booster?

[MellowVR4]

Just wanted to find out what you guys think of octane booster, some people like it, some dont. does it actually work???? just curious. If you guys do like it which brand works the best, i heard the LUCAS stuff works but??

It works, sort of. you may raise your octane rating but you'll never know how much & it will never be consistent. I would rather tune around any issues & be confident my tune is stable.

Waste of money. Get your tune straight and there will be no need for it.

thats what i kind of figuerd.

It may raise 92 octane to like 92.1 octane. /ubbthreads/images/graemlins/rofl.gif Big whoop. Spend money elsewhere.

When i accidentally put 87 in the Mazdaspeed3, I added some E85 as octane booster. By my calculations I had 93 octane after, CA gas is 91.

Top Gear math, I like it.

I tried some once, and I also thought it produced a noticeable difference but I was skeptical and thought I was imagining things. Then a few days later the wife asked what I had done to the car. She had that "have you been spending lots of money on your car again?" look on her face and I said "Nothing ... why?" She then replies "Because I can feel it is faster!"

My wife knows nothing about cars. Go figure /ubbthreads/images/graemlins/dunno.gif

I think I used STP or something. It was not cheap but I have often wondered about trying it again to see if it was my imagination or not. Lots of people say just adding toluene has the same effect, you just have to make sure you mix the correct amount.

Higher octane levels will do nothing unless a car is tuned for it. If you pour in some octane booster (which really doesn't do much), or toluene, or even some form of race fuel and the car feels more powerful...you probably had a detonation issue and the ECU was retarding timing.

 

[cheekychimp]

Feasible!

The JDM Civic Type R has a crazy CR ... 13.5 or something. Maybe the fuel in Hong Kong wasn't good enough.

Remember Japan has 100+ RON? as pump gas, which the Type R is probably factory tuned for. Do they have knock sensors on Type Rs? /ubbthreads/images/graemlins/dunno.gif The ecu could be retarding the timing because of the weak sauce petrol you normally use /ubbthreads/images/graemlins/idea.gif

 

[cheekychimp]

Yeah, that and I'm a cheapskate so I only ever fed it the cheap stuff anyway /ubbthreads/images/graemlins/rofl.gif It's been in retirement since I got the VR4 running. Maybe I should put a tankful of the good stuff in it with a couple of bottles of octane booster and go clean out the valves /ubbthreads/images/graemlins/rofl.gif

I think I'm going to run a toluene mix next year. From what I've been reading no one seems to bother with much over 30%. I'll just do a 2:1 ratio with 93. Should be somewhere around 100 octane. Only downer that I can see is having to take a few gallons of it with you every time you 'fill up'.
