Ok i have question about octane a 3.2L 03 cts (with a 63hp/52.7rwhp nitrous shot) but since you guys are a little more mechanically knowledgable I thought id ask here as well as the cts forum.

There is a gas station that sells I believe either 105 or 107 octane fuel by me.

Now for my nitrous runs i know it would be beneficial...but is there any reason that this wouldnt be a good idea to run for a half tank or so ....or if i go up to the dragstrip???

thanks for your time v-bros and i will hope to join your forum at the end of the summer:thumbsup::stirpot::bouncy:

Race gas doesn't actually add any power- it's only for preventing detonation if you're running advanced timing, really lean fuel trims or a huge shot of n20.

You could go up to a bigger shot if you're running race gas, but be careful.
