Hi,

Just wondering whats the mpg like with a supercharger fitted ?

thanks !

As with any modification it will depend how you drive the car really. You could drive it really sensibly and not rev it at all, but then whats the point of fitting a supercharger in the first place ?
How you gear the supercharger will play a big role, if you're constantly on boost obviously the fuel consumption will be heavy. Generally engines built for forced induction also have poor part throttle economy due to using low compression ratios.
Baically if your really bothered about real economy, DONT fit a Turbo or Supercharger.

If you want economy AND power your best bet is a high (relitively) CR turbo. From what others have said, typical mpg for supercharged engines is around 25, my turbo easily does 40.

15-25mpg with a bit of noisy peddel action. 70mph motorway crusie should give you 40mpg but not much more.

But thats an Vmax Scart MPI setup with a 2.7 final drive, an Emerald ECU and wideband lambda sensor, ££££.

Not sure what the carb setup's are getting.

mine does 18mpg on a normal daily drive on back roads.... 20-25 on a motorway run.

Ouch! What setup do you have?!?

Great, I've got all this to look forward to, the supercharger is in, just finishing off the final things like hte starter motor and facet. Probably get less mpg than my bros audi s8 :S

Really does depend a lot on how you drive, the Mini is a light car 'n even if it has the streamlining of a brick it still only punches a little hole through the air. The Turbo Metro had better MPG than the MG, mostly because it could pull a higher diff since it made more torque.

MPi conversion with Emerald and Wideband lambda.
I get about 28 MPG around town - giving it some every now and then. I can get 32 if I drive it like Miss Daisy.
