  • need help on gear ratios

    yes and yes i did the search on which gear ratio I should use but I was still confuse. I have a 01 camaro auto and I want the 3.42 or the 3.73. keep in mind that i live in los angeles. At thunderraing.com they go about 189.95 is there anything else I need besides liq. additives. the fact that iam going to install a cam i know that the gear ratio needs to be change [img]graemlins/slap.gif[/img] [img]graemlins/bowdown.gif[/img] [img]graemlins/omg.gif[/img] [img]graemlins/burnout.gif[/img]

    get posi, posi is a must, or almost a must.

    3.42 - These come as factory equipment on automatic 3.8s equipped with the Y87 performance package. 3.42s are probably the most popular gear ratio for performance-minded V6 owners because they offer great acceleration without killing too much top end. If you have an automatic its pretty safe to say that 3.42s are your best bet. Some manual owners have switched to 3.42s and have had good results with them as well.
    3.73 - These do not come as factory equipment on any F-Body. 3.73s offer arguable gains. Low-end acceleration is excellent and you can be assured of quicker 60 foot times with 3.73 gears equipped. However, the 3.8 V6 in naturally aspirated trim tends to fall flat on its face in higher gears--fourth for manuals and third for automatics. 3.73s will put you in those high gears quickly, so then when you actually get to the top end your acceleration will be decreased at best, butchered at worst. Additionally, with 3.73s equipped your engine will be rev quite high when driving at highway speeds, typically at 2500-2800 rpm. For prolonged periods of time this can cause excessive engine wear and terrible gas mileage

    straight from c/fbv6.com im getting 3.42,

        1DangerousV6 what about custom programing, to tune for all your other stuff as well?

        oh that is somtein else i forget, comp reprogram. when you change gears, you are changing parts that the car doesnt know about, so it will still use the programing for your old gears.

                            you won't really need to do anything if you have a manual, just get some kind of a speedometer recalibrator so you'll how how fast you're going.

                            i got mine second hand for $100.
