DeAd-EyE

So I think the blower motor in my air system may be on the out. With or without the airconditioning, when the air is turned on, there's a ton of noise and vibration (the whole dash vibrates). Someone suggested that the motor may need replacing.

Do you think this is the cause and if it is, how hard is it to replace said component? Please don't tell me I have to drop the whole dash.

fab ;)

merci beaucoup.

ce site et tres utile.

OK..i'm trying 2 find out a couple of things.

1) are there two styles of turbo twist rims?

- it seems the turbo, c4s have a newer style than the carrera's. my 99 came with turbo twist solid spokes..but the turbo twist hollow spokes on the turbo/C4S look different. also, i think my wheels had a 993 partnumber instead of a 996.

- Can i get the turbo style HOLLOWSPOKE wheels for a narrow body and if so, what are the part numbers and sizes?

- what do they weigh?

- what is the price range for a used set? my friend told me he paid 800$ for the ones on his C4S.

these are the rims i'm talking about:

2) Carrera sport design 18" wheels

- What do these weight?

- what is the price range for a used set?

Glad to see someone tackle this. I think I may have a bearing going out. Where did you get a torque wrench that would put 340 ft-lbs of torque. So you spent $285 for a special tool plus the cost of one big torque wrench. Did you get a quote for having it done? Wonder what the difference would be.

you can use a snap-on torque multiplier or a really big torque wrench. also..i believe the torque on that nut is up in the 400's...unless i'm thinking in nM instead of TQ :)...either way just make sure its **** good and tight :)

Yup, you will need to drill out the rivets.

****.. that sucks :(

i've never actually done that before. What do you need to do? just get a bit that fits in the slot and drill till you punch thru?

Is the rack which holds the owners manual under the steering column (on a 99 996) rivited to the dash? I tried taking it off, but no screwdriver will hook on whatever's holding it in, and its too dark to see what's down there.

Loren,

You seem to have great luck with Cup Car part numbers. Is there a separate PET for the cupcar?

No, the Cup Cars come with a Service manual and parts list CD (you'd expect so for $140,000 - right?).

The Cup Car CD only covers that specific model year that you ordered. Sometimes there are few changes year to tear - sometimes there are major changes year to year.

In that case, could you look up the part number and if you have it as well, the price for the 99-2001 Cup car wing (the carbon fiber version of the standard taco wing) when you have a moment.

Thanks

Loren,

Like anyone going down the "mod" road, I suggest you set your goals first. That would be in either the amount of additional power you want to make, and/or the amount of money you want to spend. In most cases, the answer to how fast do you want to go is how much money do you want to spend.

Hi I would like to start out spending around a thousand or two and see what's available and for how much from then on maybe spending up to 5k or more. Thank's for the reply Chris

GIAC flash, Exhaust (fabspeed, Agency power are great bang for your buck, AWE is also great sounding), diverter valves from bailey are also good insurence for solid boost.

I too would like to echo the saftey warnings of those much more cautious and better planning individuals before me.

i have however driven someone in a parade in one of those new mazda miatas with the two roll humps and since you will be at parade pace you probably wont be on the throttle at all (just getting the car rolling under momentum). Just make sure she's hanging on tight with one hand and not waving with both.

Once again for litigation reasons....health and saftey warnings prohibid riding anywhere other than in the car blah blah blah no doghnuts, no drifting, no 0-100-0 tests etc.

and last but not least, congratulations to your neice, she must be thrilled :).

I think it would be a good idea to compile some statistics on the wings available for 996's and the amount of downforce they can produce, as well as other important statistics which would be considered important to "go faster" so to speak.

Once we have compiled a bunch of data, I will put it toghether in a table and post it online.

I will begin searching for information and filling it in as i can get it, but others, please chime in if you have any data to contribute as I would like this to become a comprehensive and informative thread.

Please post information in the following format:

Manufacturer

Name Of Wing

Price

Weight

Material of construction

Angle of Attack

Downforce produced at X speed

Other Notes (other comments you would like to make regarding the wing).

An example of such would be something like the following:

Porsche OEM

GT3 RS (Street Car) Wing

2150 Euro

Weight: xx lbs alone, xx lbs when mounted to base/decklid

Angle of Attack: 0deg stock, 4 and 8 deg shims available

Downforce produced: ??????

Other notes: Available on european GT3 RS street car. Aftermarket replicas available in Fiberglass. Other personal comments on handling effect go here.

This is a pretty good list of wings I think are popular and worth collecting data on:

Porsche Aerokit I (99-2001 996/GT3)

Porsche Aerokit II (2002-2004/5 996/GT3)

Porsche GT3 RS (European Street Car)

Porsche GT3 "CUP" Car Wing (2002 or so cup cars)

Porsche GT3 RSR (i think the wing was longer on this compared to the cup car version because of the wider body)

Porsche GT2 (996 Turbo/GT2)

Mashaw GT2 Wing (aftermarket for 996)

MISHA GT2 wing (aftermarket for 996)

RUF RGT Wing (99-2001 996/GT3/RGT)

RUF Ducktail Spoiler

I think that covers the most common wings seen on 996's that are pushed hard. I'll cross post this on rennlist/renntech/6speedonline in the interest of speeding up data collection.

Here is the formula for the calculation of downforce:

D = 0.5 x (WS x H x AoA) x F x p xV^2 (in other words V squared)

Where:

D is downforce in newtons

WS is wingspan in metres

H is height in metres

AoA is angle of attack

F is aerodynamic coefficient

ρ is air density in kg/m3

V is velocity in m/s2

Ok, the Cup Car part require you to cut a hole in the front hood and basically use a Cup Car wiring harness throughout. Probably not a good solution for a non-dedicated track car.

The GT3 RS parts are listed in PET but not shown in any images.

Look in this list after item 37.

gt3_kill_switch_parts.pdf

I can PM you the install instructions if you want.

Loren, instructions would be great.

Just for refference, here is what i was looking for from the GT3 clubsport in europe.

http://www.cardomain.com/ride/516910/1

if you look at the photo of his interior, there is an in car kill switch just infront of the shifter where we usually put the GT3 console delete plastic piece.

if you look under his hood, there is a yank cord which is part of the factory kill switch.

Do you mean the Cup Car parts?

I believe that they were part of the GT3 Clubsport package but i could be wrong and they could indeed be cupcar parts. They're not showing up in my PET guide so cup parts are a possibility.

Thanks

Can someone post the part numbers associated with the aformentioned items.

Thanks

thanks loren!

Can someone please post the part numbers for the porsche motorsport cup car brake cooling ducts please.

thank you!

Redline User here, extremly happy with it under both street driving and hard track use. It makes tranny fluid changes cheap enough that i can justify doing them every 10-20k instead of every 70-100 with porsche parts/change interval :)

Ask me again after 20K kms with redline and i'll be happy to give you an update.

redline is a good product, just make sure it says that it is safe to use on diffrentials as well, beacuse on the 996 tranny, the fluid is shared with the diff.

I'm using castrol gear oil and have yet to have any problems. and its a fraction of the cost of Shell transaxel from the dealer (like 12 bucks a liter vs 50$..the choice was obvious to me :) )

amsoil, redline and royal purple are all quality products and as long as you stick to the diff recomendation and proper weight grade, you shouldn't have a problem.

EDIT: does anyone have a full list of approved gear oils/tranny fluids?

My clutch on a 99 C2 is experiencing the same slipping. I took it to my porsche mechanic. He has quoted me about 11 hours of labor to replace the clutch. For others that have gone through this, what has been the ballpark cost for a clutch replacement.

thanks

Umar

11 hours seems rather excessive...it should be more in the regieon of 6 hrs. this would include dropping the tranny and installing the new clutch.

did you take it to an independent or a dealer?

okie dokie,

thanks guys

<{POST_SNAPBACK}>

hey guys, mine says L32U

but there is no 32U in the paint guide above.

does anyone on here have the GT2 front bumper with 18" rims and standard suspension?

trying to find out what the ground clearance is at the front?

many thanks

<{POST_SNAPBACK}>

i just got a GT2 front bumper for my lowered 996.

i can still clear quite a few road imperfections, but on a stock car, it wouldn't be any problem at all IMO (and i live in a city with those stupid speed breakers in the middle of side streets)

okie dokie,

thanks guys

I'm pretty certain the car is actic silver.

here is a copy of my hood decal:

C36 030 XSC X54 X70

X71 X97 X98 139 220

222 224 236 340 375

376 413 424 425 446

490 859 680 896 983

09991

where is it?

hehe, i think that bumper is pretty cool.

its definitly different and compared 2 the cost of a techart bumper or 9ff bumper (only 2 i would proly take over this one), i'd go for it.

GT2 bumper's are also very nice.

it sounds like its probably the clutch but because it isn't too severe, i wouln't loose sleep over it as you prolly still have a loong ways to go b4 it craps out on you for the last time (I'm talkin thousands of kms here).

In my opinion, it will be fine for your vacation. now get a bullet proof hardtop and take that thing to bhagdad with you when your done. :)
