How to get the best performance out of a Octavia vrs

[Balders67]

Hi Please can you tell me how to get the best performance out of my 2008 Skoda Octavia vrs of Tdi.

Welcome.

Service it regularly and to get it to go the quickest it can you push the accelerator down as far as it will go.

I do service it regularly and it pulls guite quick with the engine hot I was thinking of doing a remap but I don't think the timing belt and water pump have been changed in a while.

Inflate tires to 35 psi.

Clean out EGR valve

Clean or replace oxygen sensor.

Clean injectors

Replace spark plugs

Replace filters

Check and regrease caliper guide pins and generally check over calipers

Make sure brake pads are greased around edges and back 

Get engine remapped.

given its a diesel.... this may take him a while to find replacements

why do you want to over inflate the tyres ?

There is a lot of that advice that I'd consider questionable.

 

Tyre over-inflation probably works to a very minor extent in a straight line. Round corners, with anything other than a billiard table flat surface, the car will tend to patter wide, so it depends on what you mean by speed.

The EGR valve probably does work, if you clean it in the right way, so that it reduces recirc flow. Anything else is probably neutral, or a fraction of a HP at best.

Do you have an O2 sensor? Diesels often don't, and if you don't have one it is hard to clean effectively.

Filters: Air filter could make a difference, but Oil won't

Not very keen on greased calipers; first, any grease that can get to the wrong place when hot is bad. So you might use a copper based grease, but choosing one of those that doesn't attract brake dust is hard, because if you do get brake dust sticking, or any dust sticking, you'll get brake sticking.

Engine re-map: The OP outlined some objections. Personally, I wouldn't be too worried about the water pump, which will probably go at the same time either way, but I would be concerned about the potential for belt failure if iy has been left too long (and that applies, more or less, whether you re-map, or not).

If you are concerned about the timing belt and water pump, replace them.

 

Change the oil (507.00) and filter regularly (every 5000 miles on mine). It keeps everything clean, especially in a diesel.

 

Consider a K+N air filter or change the standard air filter now and then.

 

Get a remap.

 

Drive it.
