Octane Vs. Mods

Is there a certain octane to use for certain mods? Like today i put 5 gallons 93 in to see how my car would run. I have a 3.4, 1.9, 104s, ls1 maf, DP, High Flow cat, No res, gaterback belt, and Cold air. Also for now no egr. Just wondering. I know that the Higher octane helps knock but can it hurt my car with my mods? Thanks!
 


Lol I really hope you haven't been running 87 this whole time. I'll run out of gas and call AAA before I'm forced to run 87.
 
No all we have around here is 91. Thats in kansas city. But i moved an hour north for college and found a gas station with 93. So i was wondering. Im not that dumb. lol. I know alot just not about octane. I know the knock stuff but didnt know if it could damage it. I also have a 180 tstat.
 
But will it hurt anything? I figured it wont. But i have normally injectors in there... For now.
 


Like Matt said, if you have no issues w/ knock on 91 octane, it is pointless to spend more on 93. Unless 93 is the same price as 91 in KC.
 


well im in St. Joseph and they have 92 and 93. 91 at a few places. But if 91 is only like 4 cents cheaper the 93, Why not run 93? If it isnt hurting anything. Ya dig?

LOL....I tell him that everyday. He's a Ford guy, but his FX4 was given 30 days to live by his mechanic...and the dealership offered him $10k for a dying truck. So he picked up the 07' Hemi with 35k miles for $6.5k
 
Before this thread becomes 20+ pages let me just put it this way. An average person usually drinks water. Let's call that water 91 octane. Life is good. Now that person drinks gatorade, life is a bit clearer, but still good. The gatorade is 93 octane. Now that person drinks alcohol, let that be the 87 octane. He's still a functioning drunk, but he can't climb 20 steps without taking a breath.

Now let's say that the average person was just upgraded to a bodybuilder like Zoomer. He drinks water, it works well for daily gulps, but he needs something extra. Grabs the gatorade and it helps him a little more, almost at his peak. Then he shoots up some steroids (110/E85) and is the ****ing man. But what happens if he drinks some alcohol(87)? He gets drunk off his ass after 2 drinks and can't make it up a flight of stairs without falling back on his ass twice.

Average person = average car
Zoomer = modded car

There is a difference between forced induction vs. naturally aspirated octane requirements.
