    race fuel

    would a basically stock ls1 see any decent power gains from running some leaded 110 octane fuel, and would the stock cat's hold up to it? or is this just a stupid idea

    Dude, chill out. By going off on someone who was making a joke, you're just showing people that you are the "cold and obnoxious bastard". I was making a joke, but apparently you couldn't take it. I'll edit the post if it makes you happy.

    Basically, I think calling me a cold obnoxious bastard was uncalled for and out of line.

    Werd. It's cool. People sometimes don't understand my humor either. E85 is pretty sweet though. I've always thought various alcohol based fuels could be the answer to the "fuel shortage" we're supposed to face according to all the scientists.

    no. that woulda give a benefit. screw your cats up as well with that leaded gas. also o2 sensors i believe.

    Will that be before or after you ruin the cats w/leaded fuel?

    The power an engine makes is broken down into a few things(catagorized):::--- 1)air intake and exhaust 2) how much fuel you can get into the engine 3) timing and fuel grade 4) everything else.

    if you take a stock ls1 and put in 110octane it will react badly, its not set up for that kind of fuel. if you advance timing you can run that kind of fuel(in theory). the more timing you give your engine, the more power it will make with the matching fuel

    That 110 octane gas will still have the same power, BTU, as 87 and If you don't have the compression and timing to use the octane you will have less power. You only see a power increase with compression because of the gain in efficiency.

    The lead will quickly ruin the cats and O2 sensors.
