    987 2.7L 5 speed and 6 speed gear ratios

    Anyone know the 5sp 987 boxster gear ratios and the final drive? How about the 6 speed option on the base 987? I'm trying to figure out if the 6 speed would offer better gearing at speeds below 100MPH.

    I did go to the Porsche website, but it does not have the gearing info.

    TIA

    Re: 987 2.7L 5 speed and 6 speed gear ratios

    For Manual Transmission here are the gear ratios:

    5 speed
    1st Gear 3.50
    2nd Gear 2.12
    3rd Gear 1.43
    4th Gear 1.09
    5th Gear 0.84
    Reverse 3.44

    6 speed
    1st Gear 3.67
    2nd Gear 2.05
    3rd Gear 1.41
    4th Gear 1.13
    5th Gear 0.97
    6th Gear 0.82
    Reverse 3.33

    Re: 987 2.7L 5 speed and 6 speed gear ratios

    the gearing for the 6speed is different as the torque and power curves are very different on the S.

    This is a chart I did a while ago when I was trying to rationalise the same thing. I think the figures are correct. Hope it helps. The devil is in the driving of course! in mph/rpm in all the gears for the two gearboxes. Darker banding is roughly where the torque peaks. And of course these are theoretical speeds!

    And the final drives are:
    3.75 for the 5 speed, and 3.875 for the 6 speed boxes.

    Re: 987 2.7L 5 speed and 6 speed gear ratios

    I had just this conundrum two months ago when I had to firm up my 987 options and I figured that unless you are going to spend a lot of time going to track days you would not see enough benefit to justify it. It is certainly no quicker on the acceleration figures to 60mph or 100mph that I have seen, and it is 1 MPH quicker on top end.

    I went for 18" wheels, Bi-Xenons and Sports steering wheel instead!

    Re: 987 2.7L 5 speed and 6 speed gear ratios

    Thanks to everyone for the info.

    It appears there is only a significant advantage in 1st, 4th, and 5th gears. The main two gears we use in the US are 2nd and 3rd and 2nd is identical and 3rd is only 2mph different at the rev limit.

    IMO, the 6 speed gear box is an advantage only when driving at 100MPH and above.

    I wonder why Porsche packages the 6sp with PASM in the US if there is no advantage below 100MPH?

    I'll probably get it anyways as I do attend lots of track days and plan on autocrossing it too.
