No, high octane fuel will not hurt your engine. Its the other way around.
...use the octane that is ment for your car. I dont understand why yall get wet dreams over 98 octane, or 104 octane, or 1,000 octane. If you take 91, use 91...and nothing else. if you use 87, use 87, and nothing else. If you go to low, you run the risk of pre detonation. If you run to high, you run the risk of incomplete detonation, which means LOSS OF POWER! DUR, use the recomended octane.
the falacy comes from racing gas being high octane. Its not the fact that racing gas is high octane, but how the gas is mixed. There are many highly combustable chemicals in racing gas, as compaired to pump gas. If you want to get power from gas, go to the track and fill her up. Youll run hotter, get full combustion, and by getting the higher octane in the racing gas, you dont run the risk of pre detonation. But expect to pay @ $6 per gal.

Everyone realizes that higher octane gasoline is actually more difficult to burn, right? That's why high octane fuel is used in high psi blower/turbo applications... where the compression ration really skyrockets... to help avoid detonation. Higher octane fuel in a stock LS will give you no performance gains.
As for heating up your tires, unless you've got 500hp and/or are running drag slicks, you won't need to warm them up. You do want to make sure they are clear of debris such as dirt and rocks, etc. If you warm them up too much, they're likely to get greasy and stay greasy so when you launch, you'll do nothing but spin.
Weight removal and tire pressure are your only real help. Remove as much dead weight as you can... subs in the trunk, the spare tire, floormats, hell... even remove the passenger's front seat... gotta be worth at least a 10th in the quarter. Raise your tire pressure in the front to 50psi and drop the rears to about 25.
Then again, maybe the guy was sand-baggin' you the first time so you'd drop some money on the next race.
you are right on the money, except...if he guts his car and the other guy doesnt, he will flame him for saying its not a fair race, and then guess what...another thread about a rematch. Dont go so drastic in saving weight as to be obvious about it, but enough that it counts.
I dont know if youd be willing to, but if you get tires with a shallow sidewall (ie. 225/60/16> 225/40/16) will give you a better time accelerating. its kinda like stepping up your gears by .05. I noticed when i did that, i was getting much better times. I dont know if its true that its because of the tires, but it certiantly seemed to help.
