Are there any mods that can help with fuel consumption?

22nd June 2009, 20:35

I'm looking to upgrade the 1.1 for a VTS in the near future but i've just signed a contract for an apprenticeship which will involve an 80 mile round trip when i have to go to work, college is closer.

Just wondering what mods if any can see a raised MPG?

Before anyone says it im not stripping it cos 80 miles on the motorway would be hell due to road noise and i like my ice too much to.

1.1 mpg is pretty good isnt it? bung a diesel engine in they hold records for mpg i think

22nd June 2009, 20:40

bigger stop under the throttle so you cant go to full throttle??

22nd June 2009, 20:41

Read Sayer's insainly anal (but helpful) mpg thread.

I get bout 30 - 35 MPG at the moment mainly driving short journeys on back roads and in town, but on the motorway it drops significantly cos the engine has to work so hard to keep up with the traffic. Sat at 70 ish its running at 4000 RPM which drinks fuel.

put a westy or vtr gearbox on it
will reduce the revs on the motorway as its longer geared

22nd June 2009, 20:46

according to adsayer his vts gets like 50mpg on the motor way

Was more thinking mods for the VTS but i might think about this for the 1.1, is it a straight swap or is there more work involved?

James

22nd June 2009, 20:53

my vtr could get 60mpg if i drove 65mph. i used to do 100 mile round trips to the gf's uni on 7 quid

22nd June 2009, 20:57

4k revs in 5 at 70? 70 in ours in 5th gear is betwenn 3-3.5k revs ours 1.1 must get good mpg cause on sunday we drove from glasgow to perth with the fuel light on at 70mph. which is about 70 mile's and im sure the reserve in the tank is usualy only 30-40 miles

all saxo/106 boxes will fit any other saxo/106 as a direct fit

22nd June 2009, 21:05

just have to be careful with the passenger driveshaft. The diff on the non-sports boxes is different to the sports boxes - means you need the correct driveshaft to match.

drive at 55-60mph behind lorries... ive gotten into shit nearly running out of petrol on the motorway and having to do this. you will get an insane mpg in your 1.1, as a guess probably 80 or 90+

most of your petrol on m/way is used pushing against air, and you use something like 30% more petrol going 70 than 60 apparently. If your prepared to do this on a daily basis then its the best way

some mods you can do... get tiny wing mirrors, good full synth engine oil, make sure air filter is cleaned out well, buy tyres meant for eco driving (also helps to have thin tyres).

22nd June 2009, 21:38

i get 100miles to a 10er round town...

i mine dose 70 at 3500rpm.

would a 1.4 gearbox revs be lower?

22nd June 2009, 21:49

Having read Sayer's MPG Thread i'm my future plans of:

- Supersprint race system
- Raceland manifold
- K&N Gen II

Are out the window as they will all kill fuel economy

James

22nd June 2009, 21:57

fuck fuel economy, if you want that dont get a vts get a vtr

22nd June 2009, 21:59

personally I'd lighten the car as much as possible, fit narrow tyres, polycarbonate windows, ditch the ice.. ipods are light

.. lose the spare.. Tape up the gaps in the bodywork, fold in the wing mirrors.. could even tape up the grill area but you'd have to keep an eye on the heat.

Also give up keeping up with traffic. I managed to get from cornwall to London on a tenner by being the slowest vehicle on the motorway lmao. 55mph seemed an economical speed.

22nd June 2009, 22:03

i prefer driving slow on the motorway, its relaxing sitting in the slow lane at 60-65

By narrow tyres do you mean standard saxo steelies? Do these reduce the handling/grip alot?

iPod is already linked in, but i fear the time has come to lose the sub

even tho ive just been offered a Rockford Fosgate set up for next to nothing

keep the sub. lose the spare tyre and carry a can of tirewell (or something like that)

Im going to have to try one of these relaxing drives one day and see how it goes fuel wise, must stop pretending the 1.1 is a ferrari whilst on motorways

Well on a dual carriage way today i was amazed at the change of revs when i went from 60 to 70 MPH the revs climbed from just over 3k to almost 4k which was shocking.

Bit fucked if you have a blowout though, cos tireweld cant repair that

James

22nd June 2009, 22:27

If you have a blow out you will more than likely have something more to worry about than getting the spare on matey.

True never really looked at it that way before, spare looks like it could be going. It keeps making an annoying squeaking sound against the underside of the car any way.

Anyone know the best to take the cage off/out, but have it so it could be replaced when i come to sell it?

James

22nd June 2009, 22:33

my 1.1 full tank I got something daft like 443miles. £10 usually gets me about 90 odd miles and thats short distance town driving

why is that not believable? i drove from west yorks to birmingham and back on just over half of tank, 270mile i did over all, i thought it would drink it so fast but my vts gets really good motorway miles

Well kendrick deserves it more as he made me realise i don't need the spare wheel, so i hold on to the thanls otherwise it will look like im abusing the system if im thanking loads of people on the same thread, then thanks will be removed like rep was.

James

22nd June 2009, 23:04

Just keep tyre pressures up, and even. Dont leave unessecery crap in the car, keep windows up, roll when possible.

No mods as such, but ways of making your MPG better.

I really really need to sort that guide out!

They'll be fine mate... a good thing (usually) about tuning an engine for more power is that more often than not you get better mpg than standard if you can behave yourself.

the top two should be ok (I'm running a raceland manifold), the air filter... I wouldn't bother putting on.

As said... I got 54.6 mpg from the saxo a couple of weeks ago... that was a steady 68-70ish mph with the occasional blasts for the lols

which means there is plenty more mpg to come...

Ok cheers sayer that guides really useful even if it does need sorting out.

Pleased about the exhuast, what would recommend for induction, induction kit, uprated panel filter or something else?

MPG sounds promising too need to practice granny driving not jenson button driving on motorways then all should be good

, roll on VTS too as they seem to average better than the smaller engines on motorways.

I've left my intake totally standard dude... I've read, researched, seen rolling roads of other similar vehicles with different intake setups and come to the conclusion that citroen didn't do bad on that one... the standard airbox flows bloody well... the filteration area of the standard filter is the biggest I've come across (bigger than cotton/panel filters and induction kit), which means loosely lowest restriction.

I need to get the car on the rollers again to see how it's going after the latest round of mods - basically re-installed the magnex as the centrebox was blowing all the focking time and decatted it. hoping it's around 110hp at the wheels

(standard vts has circa 100hp at the wheels, cammed VTS's with loads of the usual mods have around 120hp at the wheels)

22nd June 2009, 23:24

on the run back and too from fcs i did about 220miles in this s on £20 and that was with a bit of toe down action a massive increase over my last car.

So just leave the intake completely standard using standard filters?

i'm thinking about taking off the spare tire off. i dont even know how i can get at the spare.

only been driving it for 2 months.

Open your boot and look at the boot floor to the left of the boot catch, there will be a flap of carpet, lift that up and you will see a bolt with a groove in it, using your wheel brace (behind left rear light cluster) unwind the bolt a little then lift the cage off the hook under the car that the bolt has just lower and lower the cage to the floor and theres your spare as well as the jack.

As Haynes would say fitting is the reversal of removing.

Easier than it sounds and you would of got the spare out quicker than ive typed this lol

400-420 miles per tank VTR mk2, mixed roads.

Adsayer, did i read somewhere you were smoothing your airbox?

If so did you do it in the end?

What work does this involve and what gains did you see/would you expect to see?

James

23rd June 2009, 22:00

nope... when I checked the internal ribs there was no way of flattening them as I would have just ended up with holes at the base of the box. The car is going SORN early august so and I'll put it apart when I get a chance and muck around with most things and see what I can doooo

Cool keep your progress thread updated and ill keep checking it then

Been giving the fuel economy a go today and trying to remeber the tips in your thread whilst driving round so we'll see how it goes, probs should pay more attention to the road rather than thinking am i driving by sayer's guidelines or not...

Not all mods increase horsepower, and some breathing mods should in theory allow the engine to run more efficently as there are less restrictions in place, combine this with sensible driving and economy should be increased.

my vtr can do 108 miles that includes driving through a town and its about 50 mpg on low gears. i rekon i could do 60 mpg if i tried
