Are you brave enough...

... to see whether you car lives up to what it says in the brochure , if you have'nt already seen, we're going on a discounted rolling road day in a couple of weeks time: http://rs246.com/index.php?name=PNphpBB ... 325#114325

P.S. Admittedly I don't reckon I'll see 450 out of mine

[SteveH]

83 people have viewed this so far and no takers from a B7

Looks like we may have a B7 at the rolling road day now! (spectator so far but you never know eh Jon!?) http://rs246.com/index.php?name=PNphpBB ... 902#115902

Steve, its only really fun to rr modded cars to see what difference the tweaks have made and pick up tips from others. I've never rr'ed a standard car which has no real margin for tuning

[SteveH]

I agree with what you say there, but before being modded good to see what it can do first... Thought that the jurys out on what can be done to the B7?

Steve, I've never seen a na car modded for any real gains without adding superchargers/turbos etc. This costs £7000 + and will nullify warranty, be obviously detectable and probably decrease resale value. Hence the market for such products will be tiny, unlike your car where a significant proportion will be modded

Agree with fishface.

Turbo-engines are easy to modify/remap. Just look at what the market for tuning Impreza STi's or Mitsubishi Evo's.

To get a significant power hike on an atmospheric engine however, you need serious mechanical changes.

A remap can get you some more horses. This is because the manufacturer's map allows for a pretty wide variety of factors (lower quality of fuel, very low or very high temperatures, etc).
If you always use your car in a location like the UK (or Western Europe) where the climate is about the same everywhere and doesn't change massively during the year and where fuel quality good, a tuner can remap the ECU to make better use of the engine's capabilities.
This however means the car might not run smoothly anymore if you're in on holiday in Southern Italy when it's +42C or in Northern Finland when it's -37C, or if you once have to fill up with 95Ron fuel because 98 is not available...
(My wife's Impreza STi Type-UK for instance really does not appreciate once temperatures go below -30C).

For proper power gains, increasing the engine's capacity or fitting a turbo/compressor are indeed the only options.
This is best done by real specialists, but costs A LOT of money.

I had a quote from Brabus to get more power for of my S-class by increasing the engine capacity. It would sure have given me a very exclusive car, but the cost was much higher than what I would pay if I would sell my car and straight away buy another S-class with a bigger engine.
