100 octane race gas for me thankx

 

we only have 91 in ca ... how would we mix that toulene stuff?

 

i hate cali for tht. i remember when it was 93 then it went down to 92 and now 91.

 

We wouldn't see gain like the STi by using higher octane...I think it might only be like the GTi or even slightly less.
The power gained is typically from increased timing, however stock ECU's have a set timing map which they don't go beyond. I'd be willing to bet that using the higher octane in the turbo cars may actually give it a little more boost and keep the boost more stable since the ECU typically controls boost levels

I'd also be willing to guess that due to the fact that the GTi said 95 could be used but youd get more power on 98 then they probably have a second timing map for the higher octane gas. maybe that way for the STi too...

 

[QUOTE=simpletantra,Jan 12 2006, 04:09 PM]Has anyone else heard about what gas is cleaner burning/injector cleansing?

 

Cool vid...I alway's fill up with either shell v-power 93 octane, or chevron w/ techron 93 octane

 

i just rotate between the major brands. that way they are more effective.

 

my car ran more timing on 91 octane vs 95ish....
