1/ What petrol do you guys put in it? 95ron or super unleaded? My car is a varioram c2s.
2/ Does the aircon make a funny noise when yuo switch it on? Something like a slight whistle?
3/ Who has ever fitted a cat bypass?
1. Super unleaded; is'nt that what Porsche recommend ? and I only do low miles, so not worth penny pinching.2/ Does the aircon make a funny noise when yuo switch it on? Something like a slight whistle?
3/ Who has ever fitted a cat bypass?
2. No aircon.
3. My 993 already had 100cell cats fitted when I bought it, and must say I really like them; they have a nice burble & I feel that the car revs more easily. I asked the previous owner what brand they were and he thought they were Dansk.
Edited to say: No problem with emissions either come MOT time.

I only use Shell V-Power; luckily I do have good supply in my area and Shell happens to be the closest to where I live. Even though the car's knock sensor will compensate for a lower octane fuel, why feed it the lesser stuff for the sake of a couple of pounds per tank?
Air con noise may be a sticking or slow vent flap causing the air flow to be restricted.

1 - V-Power only. Why put fuel in that reduces engine efficiency and power? You get some of the extra cost back in MPG anyway.
2 - No air con! Saves weight in the right place.

3 - No but I have heard one and it is fantastic! Have a listen on Youtube. Illegal though and an MOT fail. Some have managed to get through them though!

1. Always super and normally V-Power.2/ Does the aircon make a funny noise when yuo switch it on? Something like a slight whistle?

2. If the noise is from the engine bay then it may be the compressor spinning
3. No
cool, thanks everyone. The engine feels very understressed so I was wondering petrol-wise.
The fan thing, I may give it a go at some point. I had my aircon fixed, but it is still not blowing ice cold and the spinning noise is not annoying, but a bit wierd.
I am planning to have go at the bypass thing. 100 cell from dansk is on the expensive side.

Are you talking about the noise coming from inside the car ie: aircon unit or at the rear in the engine bay?Lots of helpful stuff here... http://p-car.com/diy/diy.html

Just doing it !Halfway through ...
Look at my site for a guide in the next few days. Just have one pesky bolt that wont come out the old cat at the moment.
I have RSRs as well so im expecting the end result to be tad loud.

Come on Jackal... You need to clean that bit with the blue sticker on mate!jackal said:

thanks, thats kind of you .. on this one though im kind of just copying everyone else who has already sorted theirs !
The guide is coming on great as usual on your website! I am thinking of doing mine over winter as a project. My car started life in Scotland so I am fearing the worst!!!What 'special' tools would you recommend and what are the tricky bits? Anything else worth doing whilst your in there?
