Top speed in each gear, for 2.7, 2.9, S, turbo (987 and 981)

Can we put together a chart of top speed in each gear for all the different versions of the Boxster and Cayman ? I've always wanted to be able to talk about the different models in real world numbers and I just thought it would be a fun project to see the differences in actual speeds between a base, R, S, TPC turbo... ect. 2.9 987.2 Cayman 265hp- Here's my car (from the best of my memory)... 1st 35 mph 2nd 65 mph 3rd 95 mph 4th 120 mph 5th 140 mph 6th 160 mph

Downhill with a wind at my back... lol (I think Porsche claims 165mph).

When I test drove a CS (a dealers car) I bumped up against 80MPH in second gear....I think I pee'd a little.

Obviously, PAG has published these numbers for each car. They are easy to look up. For example, the 2013 Boxster Specs for top speed, PDK and manual, because they are different, are here http://press.porsche.com/vehicles/2013/2013_Boxster_Specs_Final.pdf If you mean "observed" speeds, because the speedometers all have built-in conservative errors, they won't mean much unless you pull them off a GPS - if you want accuracy. In any case, be careful here. Make sure you're "observed" speed are observed on the track and not 160 mph on a public road. Fair warning. thank you

I looked at Porsche's data in your link... am I missing something? I guess I just don't know how to turn that data into a simple mph chart? 1st 3.67 (3.91) 3.31 (3.91) 2nd 2.05 (2.29) 1.95 (2.29) 3rd 1.46 (1.65) 1.41 (1.65) 4th 1.13 (1.30) 1.13 (1.30) 5th .97 (1.08) .95 (1.08) 6th .84 (.88) .81 (.88) 7th (0.62) (0.62) Reverse 3.33 (3.55) 3.0 (3.55) Final Drive Ratio 3.89 3.89 Clutch diameter Manual: 240 mm (dual-mass flywheel). 7-speed PDK : 202/153 mm Manual: 240 mm (

Yes, you can convert gear ration, RPMs, and Tire size to mph. Google it. However, magazines have done what you ask here since the 1950s. So for one example, see 2014 Jaguar F-Type Versus 2013 Porsche Boxster - Porsche Boxster Versus Jaguar F-Type at Lime Rock in Connecticut - Road & Track The have done instrumented testing on tracks. So you can see a 2013 BS with PDK is 1 - 44 2 - 75 3 - 104 etc. Just google it. It will all be out there. As to a fair warning, I meant do not post videos of yourself doing some blatantly highly illegal speeding on US public roads. It won't be condoned. Thank you.

Thanks....

I think the 2.9 6 speed manual is wrong. I am not sure what they are, but I believe at a minimum 70 arrives in 2nd before redline. I believe it is actually 72. All i know is I got a speeding ticket ringing 2nd out and he clocked me at 70 . Thinking he was fleecing me I went back later and revisited the top of second and confirmed his gun was accurate. EDIT: Messed up, the cayman 2.9 6mt is the G87:20 transmission i believe The drive ratio of the 6spd manual: 1st gear 3.66 2nd gear 2.05 3rd gear 1.407 4th gear 1.133 5th gear 0.972 6th gear 0.822 Final Drive is 3.87 so at 7200rpm you get 40mph 71mph 104mph 129mph 150mph 177mph These are the correct gear ratios as far as I can tell, however the quoted top speed of the 2.9 cayman with 6mt is 163mph and I believe that is gear limited and not drag limited soo.....either porsche has it wrong on the ratio, or they have it wrong on the top speed. Confusing. Double Edit: After further research I believe these are correct. If you look at the published ratios for the 2014 Base Cayman it would imply that it has a top speed of 173 miles per hour (gear limited) while Porsche publishes a top speed of 165mph. The gearing is subtly different but VERY close to the 987.2 6mt. I do believe most modern Porsches are electronically rev limited and the Cayman is no exception. Guess top speed is electronically limited too, or else it is higher than published. For Reference 981 specs http://press.porsche.com/vehicles/2014/2014_Cayman_Technical_Specifications.pdf

So barring anyone finding a simple table somewhere on the web that shows top speed in each gear for each different model of Cayman and Boxster ... who would like to chip-in and help me gather info?

Here ya go Can't find base cars, no one seems to test them 981CS http://media.caranddriver.com/files/2014-porsche-cayman-s-specs.pdf PDK 44, 76, 105, 133, 160, 173, 165 981BS 2014 Jaguar F-Type Versus 2013 Porsche Boxster - Porsche Boxster Versus Jaguar F-Type at Lime Rock in Connecticut - Road & Track PDK 44, 75, 104, 132, 159, 172, 172 987.1 CS http://www.planet-9.com/987-cayman-boxster-chat/1228-top-speed-each-gear.html I - 3.31 - 5.9 - 43 mph (7200 rpm) II - 1.95 - 10.0 - 72 mph (7200 rpm) III - 1.41 - 13.9 - 100 mph (7200 rpm) IV - 1.13 - 17.3 - 125 mph (7200 rpm) V - 0.97 - 20.2 - 145 mph (7200 rpm) VI - 0.82 - 23.9 - 171 mph (7150 rpm) 986 Boxster http://media.caranddriver.com/files/porsche-boxster-s.pdf 38, 66, 96, 119, 143, 160 ​

Thanks, my numbers in the first post were too low for the 987.2 2.9 as I had a chance to try 3rd gear today at 7,200 rpms. I think your numbers are correct.

Back in my NSX days, one of the more popular mods was to install a set of short gears to eliminate some of the tall gearing that was better suited for high-speed runs in German vs American roads. As I'm still new to the Porsche world, is this something that Porsche owners and after market suppliers ever experiment with?

I think the 6 speed in the regular Boxster/Cayman has better gearing for acceleration than the 6 speed in the Boxster S / Cayman S . Not sure if you could swap in a 911 6 speed but those are even better for straight line.

When you hear a loud boom, that is to fast in that gear.

PDK Gear Ratios 981 Cayman (Base, S, GTS) : Gear Ratio KPH MPH (1)---3.91---79----49 (2)---2.29--134----84 (3)---1.65--187---117 (4)---1.30--237---138 (5)---1.08--285---178 (approx. drag limit GTS) (6)---0.88--359---219 (effectively overdrive) (7)---0.62--497---310 (effectively overdrive) Manual Gear Ratios 981 Cayman (S, GTS, GT4, not Base Cayman): Gear Ratio KPH MPH (7700rpm) KPH MPH (4000rpm) (1)---3.31---77----48 ...............

Here are the calculations I did for my '14 Base Cayman with 18" Wheels and standard shifter for 7200 RPM final Drive ratio =3.89. 1st.......41MPH.............ratio..3.67 2nd......74MPH.............ratio..2.05 3rd......103MPH............ratio..1.46 4th......134MPH............ratio..1.13 5th......156MPH............ratio..0.97 6th......180MPH............ratio..0.84

My 2011 3.4L Boxster S turns 3,000 RPMs at 70 MPH. That's much higher than expected for 6th gear,(overdrive).

I got curious about gear ratios and i did my own AI assisted research, trying to correct any bad data (AI ingests alot of forum data which, you know can be erroneous). So this is my best guess for numbers. I changed to top speed numbers to reflect the +200 rpm from a Softronic tune ... The main useful take away is the 11% and 5% shorter 1st and second gears. Interesting when compared to my power curve post (13) 2010 Boxter and Boxter S HP/TQ graph combined into one with US units | Planet-9 Porsche Forum Note: I edited the table to reflect (slighly) different final drive ratios and different (slightly shorter) 5th and 6th gears.

Hmmmmm.... if I'm reading this correctly (entirely possible I'm confused..) it looks as if a plain Boxster goes almost 5MPH faster top speed than an /S? I wonder what the comparison with PDK is (possibly the same since it appear attributable to the additional +200RPM redline on the base model.)

That's the theoretical top speed... Not actual which is limited by power/aero Also I'm using 7700 rpm (tuned) not the normal 7500...

Edited table to reflect more precise specs. no major change. I get higher speed in gears, as reported on speedometer (which i suspect overstates speed like other german cars.
