Hi all

Have my Focus RS for a couple of months now and am thinking about doing some bits to it i.e gen2 induction kit, decat and dreamscience.

How much will it affect my mpg? Any other side effects?

p.s it already has an exhaust...

To be fair you don't buy a car like a Focus RS and worry about the economy of it!!!

It's a car you can live with everyday but if you are considering modifying it then are you more bothered about how many miles per gallon or SMILES per gallon!!!

I would say just do it mate, as above its the smiles for miles value as my mate said after i put gen2, miltek exhaust with decat and bluefin on his.

if u want to improve it without going over the top, just the obvious mods are what you shud stick to

de-cat
bluefin
filter



then after that:


actuator
manifold



then maybe turbo if u wanna get serious!

Modify it


then

Get Dream Science Remap which will be much better economy as it will be mapped correctly.

remaped mine the day after i brought it and was very very happy with the results! couldnt live with a standard power one

get your self a dreamscience gen 2 and decat you can see 260-270bhp get a forge actuator and pro alloy cooler and you can see 300bhp you wont be worried about the mpg cause the mount of fun your having

What kind of damage do the bluefin, decat and filter do to MPG though?

Are the RS's like Evo's in the sense after a remap fuel economy can actually better?

pauldonachyrs

if yous are worried about the mpg get your self a tdi car

Weegi

If you are worried bout the mpg then dnt buy a focus rs like he says above buy a diesel.

i ve got a dreamscience on mine and a decat, i had the same concerns as you but to be honest if any thing its better on fuel and the car feels like it drives the way it should! running mine on the second dream map and loving evey minute. couldn't live with a standard one

I currently return 29-32mpg from my williams but want to know what an rs with a couple of mods will do.

I am happy to go to 25 on a combined run or else i will look elsewhere so any informative posts about yields would be good.

I have been told a standard rs on a combined run will be circa 30.

Cheers.

Bump, anyone?

Basic mods would be induction kit (Gen II) remap (Bluefin or Dreamscience) and maybe an exhaust (Mongoose, Blueflame, etc) - can always go for a decat too.

tbh those mods shouldnt affect mpg that much - really depends more on how you drive the car depending on what mpg you will get (same as most cars)

Bear in mind though if you dont plan to mod much just stick with the basics otherwise it can be costly - i bought mine nearly 2 years ago with an exhaust, filter, etc and said "i'll keep it like that" and have spent far more £££ than i expected and have one of the more powerful and uniquely modded FRS in the UK

Really all depends how far you want to go Ross

Cheers mate. I'm really looking for a car which has potential but a bit quicker than your average hot hatch but not evo/subarau running costs/petrol consumption.
