i live in CA and bought my EVO from a guy in MA..the car is tuned for 93. I searched and saw that the NOS brand "racing formula" octane booster boosts up the 91 pretty well but i didnt see how much of it they put in. did they put 1 bottle? or 2? are any of you guys running octane booster and if so how many bottles do you put to a full tank of gas. All im trying to achieve is 93 to get the full power out of my car. Thanks guys in advance

 

octane boosters? dont do it. just stick with 91...it wont feel as much different from 93

 

Usually its about 8 gallons of gas per bottle. But I agree that the gains per cost of any octane booster is not really worth the minimal gain.

 

why dont u find someone to re-tune the car for 91

 

Why not just buy barrels of 110 octane

 

use NOS octane racing formula but use the one that increases 6 full numbers or 60 points this is the best one!!!

 

I thought octane booster was complete waste of money. Do they even work at all?

 

They usually only boost about .1-.3 on average. Not really full octane point gains. Just mix 3 gal of 100 with your gas and you can achieve 93. Formula to figure it out:

3 gal x 100 octane = 300
11 gal x 91 octane = 1001

300+1001=1301

divided by total # of gal

1301/14 gal = 92.9 octane

 

thanks althemean...i think ill do that

 

octane boosters = total waste of $$$$$

 

glad u guys told me before i started wasting my money...would rather mix with 100...thanks again guys

 

not worth it. get a reflash for your ecu

 

no prob. glad to help

 

SCC had an REAL lab test octane boosters and they WORK......
