Hello from the US, and welcome.

Stage 0, then.... not much. The S80 was never "adopted" by the enthusiast community.

It doesn't start with the car, it starts with the car's owners. Then the aftermarket parts guys start making parts, then history takes its course.

Take the VW Beetle (old version) for example. It was probably one of the slowest cars of the 1950s and 1960s (just taking two decades out of five or six), yet they were and are used for drag racing, dune racing... you name it. My 850 couldn't come close to a street-modded Beetle, not that I've raced one, but you know what I mean.

Summary: the S80 even in twin-turbo form, one of which my dad owns, never caught with the go-fast crowd, so there are few go-fast parts made for it. Fewer still if yours is truly a 2.4 six-cylinder, which we don't have over here in the 'States, just 2.9 liters.

There was a topic on this not too long ago: S80 performance improved

Hi,

Thanks for the reply.

This is my 1st. Volvo and i geuss it'll take me some time to get used to. It is a total change/feeling driving it, after the 4 citroens i had before. It is like driving a tank, you can be sure that nothing will stop you from getting to where you want to get to..{:-)

However, i looked at upsolute web-site and saw that they promise about 13HP addition increase..etc..
http://www.upsolute.com/index.php?optio ... model=1026
since i am not familiar with all this *chip-tunning* matters, i was looking to hear from some-one's self experience.

I didnot find any similar data on others improve-car-performance web-sites..

Thanks anyhow.

Get an S60 T5. Smaller, but 80X more speed parts made for it.

Also, start with a Turbo Volvo. You can spend US$5k on an N/A 850 (or S80) to merely match the speed of a stock 850 Turbo (or S80 T6).

There are few performance parts made for the non-turbo 2.4L 5-cylinder either. S80's did come with that engine in other countries. It's got to be bog-slow; S80's are HUGE.

I think that what jblackburn was trying to say is that there aren't many and what you WILL find is generally what's available on eBay as aftermarket RAM pod air filters and the like which CLAIM to add HP when in fact they force hot engine bay air into the cylinders . The exhaust header design is already very good on the non turbos being a 4 into 1 extractor style.

Probably the best you could do is free up the exhaust with a NOISIER one and drive with the a/c off.

Thanks for explaining.

I realized that there is very little to do, and i can live with that. All my questions are to enlarge my knowledge about cars/engines, so if you bear with me a little more, i would appreciate it.

"they force hot engine bay air into the cylinders ."
Why forcing hot air increases the HP?
I thought that the more air you get into the cylinder then the explosion will be bigger, and cold air takes less volume, thus
forcing cold air = more air in the same volume = bigger explosion in the cylinder = more power..what is my mistake..?

"The exhaust header design is already very good on the non turbos being a 4 into 1 extractor style"
Does that means that if the exhaust system was 4 to 2 or better-of 4 to 4, that the air is being realised more easily = more HP..why?

thanks for answering.

Hi when I said FORCING I don't mean they direct air with any greater force than the standard air cleaner arrangement. What I mean is that the engine is FORCED to accept hot engine bay air which is less dense and provides LESS power.

There is simply no room for a any other exhaust header arrangment. Sorry I meant to say 5 into 1. I keep forgetting.

The 5 into 1 has better flow characteristics than the turbo manifolds which usually have sharp turns to accomodate the turbo, so as far as a NA (naturally aspirated) exhaust design goes, the one fitted to your car is probably not perfect but close to ideal.

Thanks. I think i understand more.

Another one- All this chip-tunning..
How come there is not even one car manufature who sell one of its' cars a-performance-chip as an option?
For sure, apart of analazing the 1st. time in what will make the car go faster, after that it's only a matter of duplicating the chip, so, for sure they can offer the chip as an option for much lesser money than all the private companies who deals with cars' performance.
What is the catch?
