Right guys, just wondering how many miles i should be getting to a full tank of petrol, roughly speaking, doing most traveling on 40to 60 miles an hour roads. c1j with Standard boost (o.5 bar @ manifold, standard t2, standard carb). Just a rough estimate please
43 litres main tank capacity, 7 litres auxillary tank capacity
50 litres is 10.99 gallons
Fill the tank, trip the meter and work out the mpg
350 miles sound too unreasonable for a tank? How much is 95RON nowadays? It's been 2months since i tanked up
Well 350 seems quite alot, 95ron is about 108p. Brimmed the tank and have got about 100 miles on half a tank, granted there has been a fair bit of spirited driving in that.
last time I did an economy test of it did 42mpg
Then again I was cheating and using EFI

What does in say in the R5 manual/handbook for combined MPG when it came out?
i got 100 miles from £20 of super last weekend

Eeeugh
used to put about 65 quid in the vee and get 160 miles odd from memery, before that beuty of a car expierdEeeugh
Then again, if everyones 5 were getting 10 mpg,its not like any of us would stop using them !!!!
My old R5's were 2nd cars so i didn't mind pumping £20 in every now and then to give it a boot full. I'd take it out once a week round the B roads for an hour, scare myself then put it back on the driveway
Id like to know what mpg the old cup car does at full chat round the track
Kris, I have a 20 litre tank and fill it to the brim before a race. At Brands in a 15 minute race we do 15 laps (15 miles) and theres not a lot leftId like to know what mpg the old cup car does at full chat round the track
My boss worked mine out to be 20mpg last week
Doesn't make me wanna get back into 5 ownership with 20mpg on the clock
with 20 psi and a light foot i have got 400 miles out of a tank one time,i say one time because it was hard work achieving it !!!
Oh come on J.....i dont believe that for a second!!!!!
I did 511 miles on one tank... and arrived with same amount as i leftwith 20 psi and a light foot i have got 400 miles out of a tank one time,i say one time because it was hard work achieving it !!!bonus
at 12psi and a heavy right foot im getting bettween 27/31mpg
as the sales man said to the chap buying the rollsroyce
when quized on the mpg
"if you have to ask that good sir you cant afford the car"
I did 511 miles on one tank... and arrived with same amount as i left
I bet it was on a trailor lol
Driving the m3 around town is proper bollocks for mpg 12mpg max, I thought the five was bad
Oh come on J.....i dont believe that for a second!!!!!
it was off boost and driving it steady thats all,just done it for fun,but in reality it just isnt going to work really is it all the time,no way,i usually get 250 miles per tank.
kin'ell, petrol must be expensive round your end... I could only ever squeeze £45.00 tops in mine and always returned 260 - 280 miles
Best i have done is 320 miles in mine off boost all the time and motorway 70mph. Quite chufted. Think the carb needs a clean now as it drinks!
raider does about 250 miles to a full tank, lasts me about a week
orange one does 180miles to a tank, but that lasts 6 months
As you can imagine at 20psi, the range is significantly reduced...my lead right foot doesn't help either...
I've never worried about mpg...I have regularly seen over 300miles to a full tank in mine...not bad for an ancient engine
Right just worked out my mpg, and works out about 23.6353617 mpg
Is this acceptable? Also when I went to fill up, the gauge was showing between empty and a quarter, when abouts does the reserve tank come into play? I know it holds 7 litres. Could only get 33.66 litres into the tank too.
On the motorway, constant ish speed, getting on for 400 miles to a tank in old whitey.
When the light comes on. You can here the pump chucking the fuel into the main tank.
Bill were when abouts does this come into play on the fuel gauge, when it's showing zero?
Near enough, but the gauge will raise again slightly when the fuel is transferred, then the light will go out. When the light comes on permanently it's definitely time to fill up, as "you're on vapour Cougar!"
W-I-N Film!"you're on vapour Cougar!"
I put £30 a week in the phase 1 and do around 200 miles. Based on £1.20ltr price thats 25ltrs or 5.5 gallon to do 200 miles- 36mpg.
Thats driving like a stole it (just ask bric, lol) at 14psi at 11.8afr
Cheers bill.Near enough, but the gauge will raise again slightly when the fuel is transferred, then the light will go out. When the light comes on permanently it's definitely time to fill up, as "you're on vapour Cougar!"
Right my brain likes to create senarios. What would happen if I went into my reseve tank, and this got used up completely and all I had on me was a jerry can with 5 litres in. Would the car be able to be driven with those 5 litres?
On a run i can get 350 on a full tank in the tungy, mixed driving. Boost 14 psi & 2nd stage modded.
I reckon fiddling with the jetting could make it even more economical off boost.
The van does roughly 300-350 on a tank, steady driving only. On boost it drinks the fuel
didnt gtt do that spider valve set up...that you could run below standard boost,get a better return that way possibly..
no one using a smaller main jet then? ie less than 1.2/1.25mm...i think mart is eyeing one up
i wondered why my ph1 used to drink fuel even at standard boost, Untill i found out the diafram? between the main carb body and the enrichment block was split and dumping fuel out the overflow pipe !!
no shi tzzle...it stank mate!!!!!
Ph1 11t had 117.5 main. I reckon this could be a winner for std boostno one using a smaller main jet then? ie less than 1.2/1.25mm...i think mart is eyeing one up
and what was i telling you?!...for weeks...

he's lucky he still got the rat.
you were telling me to stop moaning about the fuel smell in the car and give it a damn good driving !and what was i telling you?!...for weeks...
yea, if you didnt want to listen to me, i knew your fuel bill would convince you...or maybe turning your car into a mobile fireballyou were telling me to stop moaning about the fuel smell in the car and give it a damn good driving !
i always recommend a damn good rodgering
Already running one mateno one using a smaller main jet then? ie less than 1.2/1.25mm...i think mart is eyeing one up
Surprise surpriseAlready running one mate
See, now if icould have a 5 that could give me the same MPG as the 172
