Search Results for ‘pressure’

OK I have a 2017 Boxster base with 8K miles. I previously owned a 981 which I loved, but I like this car better and it knows. After a nice drive I pull into my garage and by the time I've removed myself from the car I hear a audible whistle. Quite satisfying tone, lasts about 2 seconds and is...

I was at COTA this weekend for a DE and it was HOT! 95-100 degF. COTA has a lot of long WOT straights. I noticed with WOT on the long straights, my oil pressure was hitting 70-71psi. Oil temps were holding in mid 260's to mid 270's, but that pressure is in the high side red and had me...

I thought that the TPMS for my 981 would present a value for the pressure in the tires immediately on starting the car, but it seems that my 718 needs to learn them each time. Is that what you see? For text searches: tire pressure monitoring system, wheel, zero, blank, null, initial...

I just completed an autocross with the temp in the moring runs starting around 38 with frequent rain showers. The track never dried the whole day, although the moring had more standing water than the afternoon runs. My question is how low of pressure is acceptable to run with RE71R's when...

I did a search on this forum and couldn't find any info. I noted my 981 Boxster is having slow start problems. I hooked up my Autel and pulled the following code: "P1023 Fuel Pressure quantity too low at start" Did a search an Rennlist came back with a hit on High Pressure Fuel pump may...

When my car is in normal operating temperatures (oil temp around 200), I notice the oil pressure goes to the right of the bar read out into the 70 psi range under heavy acceleration. When I check the engine oil levels, it comes back in the green. Is this normal under heavy acceleration? Thanks

My mate encountered problem with changing flywheel and clutch on his 987.2 DFI Cayman S (RHD). Initially, he bought the following: Aasco 106423-12 9LFW; 883082000884 Pressure plate 881864999959 Centre plate 99711608002 Release bearing After installing them, the clutch cannot be engaged...

For anyone here who has checked, can you tell me what your oil pressure is when the car is warm and you are just cruising along moderately in top gear around 55 mph (89 kph) ? (PDK or manual) I'm interested in an *actual number* or range (in psi or bar). My numbers are around 28 to 30 psi...

Just got a new Cayman S with 20" tires (Pirelli 265/35 zr20 95Y) from a dealer in Chicago and when the car was delivered, the tire pressure was like 40 psi for the rear tires. The door panel said it should be 33 so I let the pressure down. Then a few days later I had to take it to the local...

I started my car this afternoon and immediately got the red warning that my driver's side rear tire lost pressure, -15 PSI. So it's going to be one of those days. Quick inspection after rolling the car out of the garage revealed a screw head sticking out smack in the middle of the tire. Nowhere...

I purchased 3rd party/aftermarket wheels and tires. Of course, that darn diagnostic keeps going off since I have no TPMS...and I've been told that can't be turned-off. Any recommendations for adding TPMS sensors to each tire ? Will I have to get them rebalanced after the install ? Is 433 MHz or...

I thought this was a simple question until I started reading. Now I'm confused. As the ambient temperature changes (summer/winter) do I keep the tyres at the recommended pressure, or adjust the pressure so that it would be at the recommended pressure at the standard temperature.? (Assume the...

Ok. so a couple of months ago, my cayman (2006 S, 50K miles) developed the seemingly common sudden clutch issue, where suddenly the clutch engagement became very rough, pedal pressure was reduced, and engagement point moved up. Last week, I was finally able to tackle this problem with the help...

I was going to add this to the HDPE thread but decided to start a new one. I am a very experienced driver and one tool I take to every track event is a probe type pyrometer (Not Infrared) . I use this one Longacre Adjustable Replacement Probe Racing-Stable Energies You must take temperatures...

I've got Toyos installed few weeks ago. Stock sizes 235/35/19 front + 265/35/19. Fronts are new R888R model. Rears are R888. This is my first time with 888's and so far i was doing mountains roads driving. To get to the triangle i've got the ~36psi hot pressure. I have to say that with higher...

Has anybody here installed aftermarket gauges in the 986 or 987? I want to add both oil pressure and oil temp gauges to my track car. There are obviously both oil temperature and pressure sensors in place, the former for the electronic dipstick, and the latter for the oil pressure warning light...

I was browsing the GT4 Service Information Manual and found there is something called Racetrack mode. It says this about it: To ensure that precise tire pressure monitoring is also still possible when driving on race circuits, Racetrack mode allows individual adaptation of the required tire...

I have seen this question posted elsewhere without eliciting a reply. I am taking my GT4 for its first track outing next weekend, and I would be grateful for any advice on adjusting the pressure accordingly. Standard pressures are 29F/33R. Thanks for any guidance.

Tires, forget about the car model, would always say 32/32 cold (or whatever the pressures should be). The Porsche manuals say, for example, 32/36 cold at 68F. I understand this doesn't mean hot pressures after the tires heat up, which can be 5 psi higher. Some of these tires are so sensitive...
