    Horsepower = Torque x Rotation per Minute (rpm) / 5,252
    Gears change tq output, so it makes sense

    You run a very interesting channel. Your technical content is unmatched on UA-cam

      Thanks! There's definitely better channels though. I usually just try to make videos on things people either talk about but never have data to back up their thoughts or things I've just wondered and never saw what I was looking for.

    Wow I wasn't expecting that. Good gains! I'm probably right in between there since my G8 has 3.27 rear end. Great video!

      I've had both 3.27s and 3.42s in my ss. Sometimes I'll swap them out when I'm bored lol

      ​@andrewd843 how big of a difference is the 3.27 compare to 3.42?

    • @andrewd843
      @andrewd843  Рік тому +2

      @nastymk3 it's a decent difference.
      I've done 3.45s on a few different setups. Did a header only SS went from 3.27s go 3.45s, went from 3.27s to 3.45s on my supercharged SS. I try to gear cars based off what MPHs they'll trap and what tire sizes etc.

    My gmc sierra L83 used to be NA 4.10 gears and with new setup stroke mast performance 350CID single turbo kit by spike 11PSI meth injection puts down 645whp i kept 4.10 I don’t feel i need to change it, moves pretty well for roll racing also i swap rear brakes to fit 15inchs racestar wheels and MT tires, thank you for the helpful video

    Nice video this one did it to convince me to do the swap. But how is it from a dig. Can you hook. Or from a low roll

    • @andrewd843
      @andrewd843  Рік тому

      I have 3.45s in my LSA SS, and it hooks just fine.

    Great videos man. Been trying to learn as much as I can. I'm pretty new to e-tunning.
    What's your opion on the Blue Line Performance Probationary cam?
    I'm looking for something that'll work well with a stock TC.
    It's the gf's car so I don't wanna swap the TC yet.

    • @andrewd843
      @andrewd843  Рік тому

      Honestly, the stock converter is such a turd. A completely stock car with a converter and tune will usually be faster at the track and drive better than any aftermarket cam on the stock converter.

    What do you mean no tune changes? Would of had to tune just for swapping the dif would you not have?

      @0:44 I said the only change I'm making is correcting the gear ratio. No timing, no fueling, no anything changes. Just changed the gear ratio for the mph to be correct.

    Question did you swap out the complete differential or did you put 3.45 gears in the stock diff?

    • @andrewd843
      @andrewd843  Рік тому

      Whole diff to the camaro 3.45 it's a stronger diff vs the stock g8 one. It bolts right in with no modification.

    • @andrewd843
      @andrewd843  Рік тому

      I mean the engine doesn't technically make anymore or any less power from a gear swap but how it equates to the tire changes. Manual or auto car? 3.91s are short gears on a 6l80.

    Question so I ended up just buying 3.45 ring and pinion what else would I had to change in the diff to make this fully functional?

    • @andrewd843
      @andrewd843  Рік тому

      What do you mean? If you only bought the gears, you're going to need to take the diff apart and change the gears and make sure everything is set right.
