Got cams? How's your MPG?

22nd January 2008, 19:56

I noticed I was at a nice round number while nipping into the petrol station, so I thought I'd have a crack at seeing how far a full tank would take me. I was well into the reserve area, and I filled it until it clicked whick worked out to be 39 litres of BP Ultimate. Anyway, from this 39 litres, I manged 320 miles. As 39 litres is 8.58 gallons, that works out to be 37.3 m/g

To try and keep the test fair, I mixed it up with about 40% town driving and 60% motorway. I also gave the car some stick a few times, and didn't just poodle a long trying to conserve fuel. Bare in mind I'm also using an S1 gearbox, so the revs are constantly high on the motorway... What do you recon, good or bad fuel economy? If anyone else knows theirs, please share!

22nd January 2008, 19:59

i think you drive like a girl

tbh id be happy with that mpg.

22nd January 2008, 20:01

jesus fucking christ i am lucky to see 260 with my vts thats without cams. Belly vts was saying he gets more with cams and a remap then he did standard.

am getting book standard 32mpg

22nd January 2008, 20:07

It would be better with the stock gearbox back on. Aye, it's not too bad after all then.

22nd January 2008, 20:37

I average about 310-320, Little bit of town driving with some motorway.
Boot it a little but tend to cruise between 70-75.

22nd January 2008, 20:38

in my old gti on piper 270s etc I used to get 355miles to a full tank at £40 that was mostly hard driving some slow town stuff

22nd January 2008, 20:39

I get about 20-25 mpg, and i have a S1 box too

22nd January 2008, 20:42

everyone gets better mpg than i do in my stock vtr lol!!!

i do have a heavy right foot though

22nd January 2008, 20:47

i only get around 25 and thats near enuff stock

22nd January 2008, 20:48

i only get 200 miles to £40 of petrol in my 16v rallye.... think i might check my lambda sensors working.

thats excessivly bad, something must be wrong there

22nd January 2008, 23:58

I get roughly 60 miles on 6 gallons in the 1.4.... LOL

23rd January 2008, 00:03

toady thats focking good.

must have been mapped pretty sweetly. nice one

edit: foggy... on the other hand, that is bollocks... although your engine is mad and quality.

23rd January 2008, 00:31

I really need to find out my mpg because i think its really bad...

ive spent like 200 quid on petrol and ive only had the car a month :o

23rd January 2008, 02:22

i was getin 15mpg last month and thats a 1.1

but now i have done tappets and some other lil bits seems to be around 35 mph plus its 99% town driving

23rd January 2008, 02:23

iv'e recently had a full tank of fuel in my mk2 vts, standard barring decat\stainless thru system and induction and ive had 322miles to £45 v-power (£1.11per liter) which i work out to be 35.7 mpg (322 miles divided by 9 gallon)

mixed town and motorway and some a bit of heavy right foot - im happy

23rd January 2008, 06:36

you must drive like a girl to get that MPG, i got about 220 with cams and map. drivin hard or not still teh same.

23rd January 2008, 09:39

my mini cooper s is tellin me im averaging 22.5 at the mo

It runs rich below 5000 rpm... haha

23rd January 2008, 18:21

I tend to get between 55-60 miles on ten pounds, which I believe is between 25 - 28mpg. That's a mixture of normal and slightly quicker driving in and around urban and motorways. Car has piper 285cams and few other bits

23rd January 2008, 18:40

i get about 150 miles to £20 in my VTR

standard except a decat and backbox

Just out of curiosity, why do some people use bp ultimate/v power in there saxos?

23rd January 2008, 20:30

After some toddling along on the motorway at 60 I found mine to be pretty good.

Got no figures as there only going to be estimates. Cant be arsed. Its crap
round town. The missus Fiesta Zetec S is teribble on the motorway doing the
same treck I do to work! I seen the tank depleting

(the needle you fools)

23rd January 2008, 20:31

LOL - I use V Power. Dont do much imo, just nice to know that decent fuel
is going in the car. GIGO?

23rd January 2008, 20:35

I think thats a great MPG !

Would be nice if i had it.

23rd January 2008, 20:44

I dont really know if v power is any "better" than normal shell unleaded, yeah its a higher octane. May contain less shite i suppose.

IMO i wouldnt bother. If your cars mapped for higher octane fuel its a certainty, but if not i wouldnt waste the extra cash.

23rd January 2008, 20:47

I know where your coming from mate.

My reasoning is just thats its a better quality fuel, not worried about the octane.
Its like using that Silkoline oil, you dont need to but its very good?

23rd January 2008, 20:51

I just use normal sainsburys fuel.

fuel is expensive enough as it is. without buying that shit.

plus my car drinks like theres no tomorrow.

defiantly needs setting up. just need to find the right place and decide where im going with the car!

23rd January 2008, 21:06

Can get just over 400 miles to a tank inc some hard driving if i'm careful most of the time in my vts. Can dip to just over 300 miles to a tank for hard road use, and well below for track use. With cams i could get over 400 miles to a tank with wideband on and being conservative, on track i got down to 15 mpg though.

I try to keep the revs up a bit.

Nah, it's not running stupidly rich, but it's still rich. It happened once the big valve head went on. I need another map done, but won't be getting the stock ECU re-mapped again. Waiting for the big jump forwards to bodies...

Oh the old bodies trick is still on the cards aye

Watch our section for a custom bolt on throttle body kit soon!

I agree, i stopped running my mr2 went v power went to 105.

Its just not worth it. Standard stuff is good enough!

24th January 2008, 01:31

dunno y but my furio ran smoother on tesco super..
wont be running the vts on it tho as im expecting worse mpg compared to the 1.4

24th January 2008, 04:16

in my total honest opinion ive driven my car on v-power for yonks an if i put ordinary petrol in it doesn't feel as responsive, its definate difference that i notice, v-power seems to be smoother tad more responsive and makes my exhaust pop like a bitch....definately not worth the ridiculous price of £1.11 where i live tho

pay that for normal unleaded in whitby mate

Welcome to my world lol

24th January 2008, 12:20

im pretty sure v - power is 1.19 near me!

24th January 2008, 15:51

Got 40mpg out of mine once.

Key is in the map

Ordinate Survey?

24th January 2008, 18:05

i get arounf 200-240 m iles to a tank of ordinary unleaded in my vts bt thats with a low ratio box in aswell!! majority of twn driving!! getting cams and a remap atm so i will see how the mpg differs then!!

24th January 2008, 19:02

180-200 miles on £40!

26th January 2008, 12:40

lmao u lot must rag the bollox of ur cars, i done 340 miles yesterday to a tank as apposed to the 322 i had b4. drove from where i live to sheffield to lincoln back to sheffield and then to grimsby and that did include some heavy right foot action when my outdated sat nav sent me wrong an i had to back track.

28th January 2008, 02:16

mk2 vts decat/panel filter,magnex system

50 miles for £10.
is dat good?

"dat" isn't too good, that makes a full tank last you "around" 200 miles.

To answer the original "got cams? hows mpg?" question

It doesnt matter if you have cams or not, ecconomy of an engine is down to how much fuel it uses, not much fast the cams get the gases in and out.

Our demo car will have the economy to match "there or there abouts" a standard VTS. but running 170+ bhp.

30th January 2008, 08:49

I'm not so sure, but feel free to prove me wrong.

If you want more power you have to burn more fuel, hence why bigger injectors come into play when you hit around 165 - 170 bhp on the VTS. Think about it, if you've got camshafts which are holding the valves open for longer and also creating more lift, you're doing this so you can get more fuel and air into the combustion chamber. Obviously the map will be important with regard to the economy of the fuel consumption, but you can't produce an extra 40 - 50 bhp on the TU engine without burning more fuel, it's impossible.

but when you're running your engine at part throttle i.e. cruise (not as in CRUZZZZ) mode as opposed to boyracer mode, you arent going to be producing the extra 50hp. your engine will be producing enough power to hold the vehicle at the desired speed.

30th January 2008, 09:15

OK, but this depends on what speed you are sticking to, and at what RPM the engine is running at. I don't see what you're getting at here to be frank.

You're not going to get better fuel economy by fitting higher lift / duration cams, as the engine will become less efficient in the lower revs.

brake specific efficiency drops in the lower rpm but also increases in the upper rpm - but again that ultimately depends on the quality of the map.

at work, will explain later (if someone else hasnt), bump this this evening.

30th January 2008, 17:44

when we map a car. we do it such that at 70mph in top gear (at whatever revs that may be) the engine is at its best efficiency (at whatever TPS that may be). thus burning probably less fuel than standard. then as the throttle is punched, fuel goes in, etc.

30th January 2008, 19:10

I get about 50miles less to the tank compared to a standard vts when on the motorway, thats with an engine 50bhp up on standard as per my sig.

I know what i'd rather have

Daves right when he says the key is in the mapping!

Can you do maping? If you do might come to you then when i get my cams done

30th January 2008, 19:52

We supply and fit standalone ECU's. We don't remap the standard ECU.

30th January 2008, 20:04

My cammed vtr is no different to my non-cammed vtr... might be a bit of a difference but nothing major.

12th May 2008, 20:54

how are u complaing about that i got 300 max in my standard vtr, u most drive like my mum

12th May 2008, 21:35

haha i get about 5mpg

its a piss take
i can just squeeze 200 miles from a tank

13th May 2008, 08:31

im getting about 37/40mpg. i usually put £15 and get anywhere between 110 and 120 miles to that.

13th May 2008, 12:07

Since i've fitted a decat i get about another 40 miles to a tank, fuel guage is just under half and i've done 220 miles.

Have to see what i get with 708's.

13th May 2008, 18:50

when i drove down to london before me cams, i use to get exactly 300 miles out of a tank every time. now after after the 300 miles i still have 1/4 of a tank left.
