i own a 2000 v6 camaro 3.8 im using nitrous 120 shot on 87 unleaded i was thinking about using like 91 and mixing in alitle 101 in it or just strait 101 octaine but im not sure if this would be harmful considering the car only wants 87 but im using nitrous can someone help me out here thanks?

 

you want to use the highest octane rated unleaded you can find i beleive its around 108 and run it as a 60/40 or 70/30 split with pump gas...70% being the
higher octane and drop about 3 degrees of timing. you should be safe then. don't use leaded cause you could burn out your o2 sensors and cats. hope this helps

 

If you have it tuned at a dyno with exhaust temp sensors etc, you can find out exactly how much octane you need to run the bottle right. Higher the octane rating, more safe your runs will be. Too little octane and you can cause detonation, which is bad for the motor.
