    What brand of octane booster do you use or do you use in at all?

    On a stock cat just a good grade 93 is all you need, haven't seen any data to prove other wise...

    I think the manual says not to use octane boost products.

    Yeah but wouldn't an Octane booster eliminate the bad gas effect? Pulled timing = HP

    a better test would be in an actual octane tester, but it shows if you don't need it, it won't help

    I use Aces IV in my Charger all the time. I use it for the lubricating properties to deal with the ethanol in the gas, but it eliminates the slight timing pull I was seeing

    That's because the vette was most likely tuned for better gas, I doubt Lingenfelter just put a CAI on it and pasted a logo on it.

    I read another test on octane boosters that measure the octane. Most of the boosters did boost octane but only by points not numbers. Points is tenths while number is whole. If a booster says it will boost by 3 points then the octane will go from 93 to 93.3 This what most boosters actually do.

    In the test I read only Lucas and Torco increased the numbers. I can't remember for sure but I think Lucas increased from 93 to 97. Torco went from 93 to 99.

    One thing to remember is octane basically just increases the temp needed to ignite fuel. If your engine is not tuned for higher octane you may loose power as shown in the video posted earlier.

    There is no knock at 93 octane in hellcats. Hellcats are tuned for 91 octane.

    I plan to datalog the Cat this spring/summer with my Trinity and watch for knock retard. When I datalogged the 09 SRT in really hot weather here, I found I had to use about 95 octane to eliminate most knock retard. I did that by mixing Sunoco 100 with 93 octane. Unfortunately we have no source for the unleaded race gas now.
