500hp on 85 octane. That's pretty damn good.

thats what im sayin.....im not gonna flame on but idk abt all that. why wouldnt you wanna run 104 or higher since you make can make more power with higher octane fuel. i know when i run my t-type on 94 and then on 104 i gain roughly 1/2 sec or more dependin on the temp of the day...... that pic looks like a granada than a 02 dodge stratus r/t to me sir

thats not a Stratus RT, which should be pretty clear....and that granada is the 500+ hp car were talking about...
its the "old dodge" that i made reference to above. your post didnt make a world of sense, but i think what youre asking me is why wouldnt i run higher octane to make more power? just putting higher octane in a car doesnt make any more power. you have to have the compression ratio which can use the added octane. if you have a supercharged car, yes, more octane is better because you have very stiff compression, especially under heavy boost. on the other hand, i run 8.5:1 CR, so adding much higher octane only costs more, and doesnt improve the power. for now...its with my dad who built the motor right now, getting new seals and bearings, new valve springs, a new timing chain, new shoes..and 4.56 gears...the end result should be low 12s for now, and i will look into domed pistons, which will increase the CR to around 11:1, at which point i will run straight 120 octane, but for now, im havig fun with nice cheap gas. and my car with its cheap pump gas hurt alot of feelings last year on the national circuit.

Higher octane also prevents engine knocking. On the Cooper S models, you have to run 93 octane or more to prevent pre-ignition.
