In todays climate, how far is £50 going to get me?

I think you have a problem then with your car, eating too much fuel.
 
Does anybody find that driving around town slow gives you the same mpg as thrashing the pants of it?
 
I do..roughly ten pounds = 35 miles and on the motorway 10 pounds 40 to 45 miles? This figure is the same on my 350bhp rex as it was on my standard rex. Im finding the mods have kept the economy the same. Any comments.
 
Also would be interested to know how much mpg the big turbo/uprated fuel system guys get for their cash anyone like to comment?

[DR SCHNITZEL]

wow answered before i asked lol.
Your single is giving you better mpg than my twins with apexi??
 
Is this the same across the board with you single guys. I understand if your motor is ported you will have dreadful economy. what kind of MPG would you expect with a street/ bridge ported single?

Yeah, kinda.  It does seem to use not much more

I usually fill up for around £66 and in summer would get 240miles of every day driving.  I used a tank in 2 long journeys and only drove with fuel in mind (which bored the cack out of me so dont reccomend :Laugh ) and I got an amazing mpg but thats all down to crusing along at 65 and trying to stay awake!

I heard the economical sweet spot was 84mph?

[m4drx]

mine is on twins but soo rich!

i do have a theory about it using similar fuel if you thrash it.

thrashing it = heat = higher intake temp = less fuel injected = more mpg

i noticed this as short journeys are a joke in mine!

need it mapping. loads of popping too, which i\'ll miss tbh.

Depends on a number of factors - my ports are big but not huge but, due to the size of the turbo I\'m not continually in and out of boost everytime i touch the throttle.

It\'s when you build boost that the rex eats fuel so later boost or less responsiveness than a twin setup will be generally more economical.

On boost more power = more fuel so my rex running > 400bhp is less economical than when it was standard.

We spend more time on part throttle then we do booting it or we\'d all be dead or locked up

the less i put in the longer it lasts...
if the tanks brimming i dont care how much fuel i use.
but if i only fill it up to the quarter mark i can make it last for ages. not in the spirit of things i know but if im skint it works a treat!

i put 78quid in my rex and it did 225miles to london, no traffic at about 70-80mph, obviously i was doing 80 in the fields next to the m6 as its illigal to do that on the road itself

£50 in my bridgeport was getting me about 60 miles lol couple of trips to work and back!

[RobbieRX-7]

Mine\'s costing £1 per mile on stock twins with no boost. I think somethings wrong as it never used to use this much before. Im gonna try a new lambda and see how it goes

[S3TH]

u think somethings wrong...? hell dude, get that **** checked out... :spank :Giggle

is it bridgeported??

[RobbieRX-7]

stock ports, stock injectors. Decatted only running 320bhp. Im hitting 100% injector duty and hitting fuel cut over 6000rpm. It was mapped by wgt 1 year ago so i hope the pfc has not lost it\'s map. Im thinking either leaky injector(s) or faulty lamba sensor. Anybody else got any suggestions?

[olly-civic]

wouldnt it be an idea to get some boost so it runs properly?

sounds like if your hitting 100% injector duty your mapping has been changed. Thats gonna straight away bring you into high running costs lol. whats your injector duty on idle??
