Now i know people drive differently and some have mega power but roughly what are people getting mpg normal driving with about 250bhp?

 

should be getting way more than 300 miles to a tank at that power

 

low 20's round town and about low 30's ish on a steady run, this is on my mega powerfull(not) 260 bhp small turbo esc cos

steve

 

i used to get about 180 mile to 40 quids worth of petrol in my stage 2 saff cossie.

 

ok what do people see with 450-500bhp engines...normal driving and gunning it

Dan

 

i used to average around 200-225 miles to a tank.

personal best was 150 miles

 

250 miles to Ł45 taking it easy obv lol.

 

i never bothered to work it out, just keep putting it in. was too painfull to think about!

 

i had as much as 30 when it was on yellows @ about 250hp
most ive had on the current set up (greys at about 380) is low to mid 20's

you would be hard put "gun it" for a full tank unless you are on track Dan!

 

I'm getting consistantly 35+MPG with around 310bhp on a run!

Edit to add, I can piss 350+ Miles to a tank even with some 'spirited' motorway driving! This is better than my E36 328i BMW on a combined tank of fuel!

 

i get around 300miles with my 330-350bhp

 

Wow I must be lucky. Have done 1500 miles this year with around 450 bhp (408 at the wheels) in my rs500. On my runs and when I've kept my cool I've had better consumption that with my standard 2wd saff! Its down to PJ motorsport I guess, he asked if I wanted good cruising economy when he was mapping the car. Last run I got 37 mpg so I am even happier having read this lot. My saff manages around 33- 35 at best.

Boot it and I've dropped to 14mpg - but that run included 5 laps of Silverstone. 65 ish is off turbo most of the time so thats where I drive when I want to conserve fuel.

 

450 bhp is 408 atw? so that means theres a transmission loss of less than 10%?

 

I got from my first full tank 385, but that was mostly local stuff and some small blasting.
I gained 140 miles to a tank after remap as well as 30bhp at 3psi less, glad more than ever now I went aftermarket ecu.
That's on HIGH setting, don't know about LOW setting but would obviously be more.

48 mpg then, was that a diesel or a prius

 

i got almost 30 mpg coming back from msd i remember because it was almost double to when i took it there

 

Same as me used almost a tank getting there and half getting back

 

I've managed to cain a full tank in my stage 3 escos in 100 miles but it's normally around 200 miles. Might have something to do with the prehistoric bayjoo chip or so i've been told.

 

Thats what I meant matt, all out gunning it!

Dan

 

If driving it very hard well under 20 mpg, infact it can be down around single figures.

On the motorway at a steady 70-80 off boost I've had 33-35. Pretty good really.

 

if driven hard then i get around 75 miles from Ł30
going to the ford fair i filled the tank Ł55 at the time & got to lesterforest services think its about 170 miles at 80-90mph

 

My old RST used to give me 60 miles to 20 quid.

In 1999

 

thats more than both my vectra turd and about the same as my a3 lol
oh nd about double the sierra

 

why buy a performance car and worry about ecomony

 

Think someone needs to go back to school 385 miles to a tank after remap on new ecu easily, but boring avarage nearer 320/340 as didn't buy it not to use it.
385/12 = 32MPG.
tabetha

 

your previous post stated 385 from a tank and that you got an extra 140 after a remap
385+140 = 525

 

poous has just returned 520 on 45 litres urban
does better urban than on a run lol

 

yeh but ur old enough to drive one without the embarassment , also do you work for green peace

 

mine was same as a stage 3 on a cruise.

 

Why buy a performance car and worry about the fact the fuel tank leaks? Same thing isnt it?

You would have to be extremely rich AND stupid to actually WANT to spend money on fuel you didnt have to.

Apart from that, filling with petrol is one of my hates in life, such dead time, such a waste. i really hate it.

 

this is true BUT how many people actually stop and think shit i hope my 500 bhp cossie does 38 to the gallon , my point is economy isnt the first thing on the list or requirements when buying a tuned car but mabey rises up the list when the sinking feeling hits after spending a fortune on rebuilds ect

 

5 to 28 mpg !

 

i put 22 litres of optimax in and got 100 miles. its a sapph on greys t4etc, that was a mix of cruising and caneing.

 

i've used 2 tuners now (with the cossie) and every time the power goes up the fuel econ goes down............i can do 30mpg, but dont fuckn want to...................long live my right foot.........

 

Stage one saphh msd closed loop chip,about 100 miles spirited driving the rest back and forth to work under 10 miles each way,300 miles at least from petrol light to petrol light

 

thats nearly a litre per mile! fair play.

Dan

 

with our fuel costing upwards of Ł4 a litre then yes im very interested in NOT wasting fuel, you might as well chuck Ł40 in the tank and just give Ł40 to cashire as a tip

no excuse for poorly running causing excess consumption.

 

where did i mention poor runing ? and what cossie is good on fuel when used in anger / how many stay off boost and cruise on a motorway at all times , fuck this place is getting a little serious

 

if your using more than is required then its poor running, nothing but serious in here, i personally dont like to piss money away, maybe you do ? good on you if you have enough to do so.

and as for the cossie that is good on fuel when used in anger, heres a small example for you, my last rally car, when on stage mapped by a well known mapper would return me approx 5mpg, after a change in mapper, and a totally differant map, same spec, i would then return nearer 10mpg, i call that a great improvement, and can only therefore sumise that my last map was incorrect hence poor running, you may not feel the effects of poor running, only on your wallet by the sounds of it

 

Jay, your arguments poor. Do you think F1 cars get used hard? Yes, me too, and they are the number 1 innovator in fuel saving mapping tecniques and gadgets.

We also know that they CAN afford to throw it away if they wanted to.... lol
