Ill stick to running 93 octane. changing my oil every 3500 miles and doing all my tune ups on time everytime. to say theres no differnce between regular and 93 octane you would have to be retarded. go to a gas station try it. performance mods can give you performance but it is always at a cost. and yes removeing your a/c and fan can give you more horse power.
I'll hop in and let you pick on me if you want.
To start I built a lt1 to run on e85 ethanol, it made 628 on the dyno. I'm sure you know little about lt1s but that is a lot. Usually make mid 5s on race gas. Now how I did it was 14.1 to 1 compression and a custom grind solid roller cam, and of course Afr heads. Tell me again ethanol is junk, by they way most racing association are running ethanol now
An engine is an air pump, the more air, the more power. The key is proper tune, and efficiency. Now take a worn out engine with 8.5 to 1 compression, and you can run whatever gas you want in it,
Octane is the speed of burn, higher octane burns SLOWER. Therefore making less power, and efficiency. The only time you need higher octane is when you raise compression, or advance timing. Or add boost aka raise compression.
Newer flex fuel engines get less mileage on e85 because it is a cooler slower burn, it is also very high octane, and the computer has to put more in. The difference in these engines and normal engines is they crank the timing when running e85 and make more power.
I'd love to hear your theories on biodiesel as well as I burn around 20,000 gallons a year of it in my machinery that has $20,000 engines in them.
