As for the BMC CDA, I've already done that



sam

I always love a nice carbon fiber part .. but what is a BMC CDA ?

[jaykay]

Third these ideas....plus oil pressure and temp, voltage indication kit. Perhaps this could be done via a nav screen

Rear adjustable toe control arms seem to be very expensive for what they are.

Automatic fire suppression system for the engine compartment.

Got some updates on the spark plug tube. I just picked up one and dropped it off at my partners shop. Hes gonna discuss it with his machinist and see what we can get done.

Aluminum 6061 seems like the material we will be using though. I'll have the parts drawn up by tomorrow, and ill run some tests on it to make sure we wont run into any issues like thermal expansion etc.

We are guessing that porsche chose to make the tubes out of plastic because its cheap and also acts as a heat shield to protect the coils. Our solution will be to try adding a thermal coating to the tubes.

The final issue is the O rings. the OEM o-ring looks like its very high quality, that said it still seems a bit expensive for what it is, we will try to source a cheaper one with the same quality and include it in the kit.

Either way, i'll post more info as i get it.

Thanks again for the feed back

For the AOS. Would you guys be open to replacing the entire system with a oil catch can? We could design a kit that replaces the factory AOS with an oil catch can.

An oil catch can would do the job as efficiently and would be more reliable, as you'ld never have to worry about replacing a leaking AOS. Plus it would look pretty cool installed IMHO

[The Radium King]

i can't speak from experience, but others have done the catch can and it can fill up in higher-g/racing situations, so not a maintenance-free solution like the AOS (uh, ... not that the AOS is maintenance free ...).

[rayner@r2specracing]

The machinist says its not a problem, does anyone have a used coil pack they want to part with so we can do some measurements off it? thats the last thing we need to do.

It doesnt have to be working we just need to make sure everything fits before making them

[rayner@r2specracing]

Heres a pic of the spark plug tube. Its drawn to scale, we're gonna perform some tests on it, then we'll give the machinist the drawing to make a prototype

After that I'll put up a thread setting up a group buy



the black area is the thermal coating

I can help you with that. pm your address and I will get it to you.

Lightweight clutch pressure plate

Boxster S exhaust system with optimum tubing I.D. for street driving RPM

Air Oil Seperater improvements ie. a screen/filter that mounts on the 97-02 head where the boot attaches.

bmc is the company, cda stands for 'carbon dynamic airbox' - an inline cold air intake.

steel or alu; i would let the engineer advise as to the most suitable material.

re. gauges, plx has a multigauge that can display data in various formats - obd info from the computer, or specific sensor data (can mount in a 987 pod on the dash or a steering wheel pod). if you want oil temp, your stereo has the ability to display that. if you install an oil pressure sender on your motor and run the wire forward, a 996 gauge cluster will give volts and oil pressure.

What is required to get an oil temp displayed on the radio?

Check that out, Miken.

I know it's not the radio, but it's a way for you to see it.

EDIT: And I just realized by your sig that you've got an 06, so I'm not sure that this would apply any longer, but still an interesting thing to know.

[The Radium King]

my bad; i meant the ac unit not the radio.

ps; you r2specracing guys rock; this is excellent.

Car diagnostic tricks which works on 1997- 2000 boxsters.

There is some sort of serial data stream or CAN interface that allows the AC (manufactured by Audi) unit to display engine parameters. Here is a list of what can be seen:

To switch from F to C:
Hold down the recirculating button then push both the temperature + - buttons.

To access diagnostics:
Hold down the Recirculating & Air up buttons for 5 seconds.
The + - buttons go up and down through the list of "c" codes.
The center vent button switches the left display between the "c" code and its actual value.
Press the Auto button to exit.

0c - ERL
1c - Oil Temp?
2c - Inside temp. Sensor mounted in the aspirator assembly at the side of the dash.
3c - Outside temp. Sensor located inside the air inlet of the A/C unit.
4c - Outside temp. Sensor located in front grill of the radiator. The data is fed to the climatronic from the instrument cluster. When not moving, the instrument cluster OBC temp display retains it's last setting until moving. This is to prevent heat emanating from the radiator affecting the temp. sensor. The A/C unit uses the lower of the two outside air temp values in determining fresh-air temp.
5c - Outside temp. (matches with OBC outside temp display)
6c - Coolant temp.
7c - Footwell discharge temp.
8c - Sun sensor (dash top)
9c - Sun sensor.
10c - Passenger compartment fan speed.
11c - Passenger compartment fan voltage.
12c - Temperature mix Flap command 1=COLD, 100=HOT
13c - Temperature mix Flap position
14c - Central Flap command
15c - Central Flap position
16c - Footwell/Defrost Flap command
17c - Footwell/Defrost Flap position
18c - Recirculation Valve command 1=OFF, 100=RECIRC
19c - Recirculation Valve position (feedback)
20c - Vehicle speed in kph, updating only once per second. (real speed, not speed+safety margin as in the speedometer)
21c - Engine RPM in hundreds. This too only updates once per second.
22c - ?
23c - ?
24c - Sun sensor, exterior lights switch & panel lights control (term. 58 & 58d voltage) - used for A/C panel display illum.
25c - ?
26c - ?
27c - ?
28c - Fan speed?
29c - ?
30c - Engine run time in seconds (255 max.)(=0xff)
31c - Timing counter
32c - Displays test
33c - Software version? Mine states 3.4
34c - ?
35c - Outside temp. from inlet sensor (filtered?)
36c - temp?

Happy Boxstering,
Pedro

I tried that sequence on the 987 and got nothing. I'm guessing that the data is still in the DME; any other thoughts of retrieving water/oil temps from the 987 DME?

that process only works on early 986 cars. any of the aftermarket obd devices should give you that; there's even apps you can get for your ipod i believe.
