Good read on octane ratings and engine compression
I was checking out some totally random things on howstuffworks.com, and found this.
It explains what those strange octane numbers mean, as well as how they interact with the compression ratio of the engine in your car. So, if we did manage to lower the compression ratio in the SVX with different pistons, we could technically use 89 or even 87 instead? Sweet! Naw, I'm just dreaming and I know it... Damn, I hate these gas prices. :rolleyes: |
Well, technically you're right, and if you really wanted to you could get low comp pistons made up. Only thing is, you're gonna lose power. It's a tradeoff.

Exactly. And I want as much power as possible in my SVX! :cool:

Well if you put it that way, then get those lower compression pistons! :D However, once you add a S/C or Turbo, you'll need to switch back to Premium depending on your tune.
Both my 300ZX TT and SVT Lightning had engine compression ratios below 10:1, but needed premium gas due to 'forced induction'! :) -Chike Quote:
