MPG

[iain01]

know this has been discussed before and had a look at previous posts.

I  have a 01 wrx fitted centrepipe and racebox last year. A couple of weeks ago I fitted a K&N panel filter and got second cat removed with decat pipe fitted. The car is running smoothly and pulling well with a slightly better throttle response, but seems to be using more fuel. Worked out that I was getting around 22mpg after the decat pipe and filter were fitted with moderate driving. Does that seem about right?

Maybe its just a case of paying more attention to the fuel gauge because I've had those mods done.

I thought i was getting great results with the 555[]. then remembered it was only the speedo overlay that was changed to MPH and I hadnt had 320 miles but 320 km to the tank[][:$]

I got 150- 160 miles for £30 of tesco 99 (vpower is very scarce in south ayrshire, bp everywhere)

Before Group N filter and less restrictive backbox = 290-310 miles a tank

After Group N filter and less restrictive backbox = 240-260 miles a tank

I've been seeing around 250-275 on a 01 WRX with prodrive BB and green panel filter running on V-Power.  Just got the 3rd cat removed last weekend so I'll see how that affects economy..

Sounds about right. MY06 3rd Cat delete, de-resonated centre and Prodrive backbox, just over 21MPG. As Craig says 9-10 on track ouch! I did get 24.74 one week, but this was because I covered a lot of distance driving at moderate speeds (wife in the car throwing up in to a polly back as I negotiated the twisties!).

 Craig,

is that with major mods?

well i must be on my own here,i have never bothered calculating my mpg,if my cars running fine,and, the needle goes near the "E",then i fill up.

What i found was that pressing the loud pedal=needle moves faster towards the big "E"

Less pressing on the loud pedal=slow moving needle.

......simple really.[]
