Right after venting in 45 litres of the black stuff I'm almost at 470 miles for the tank, what is the maximum amount of diesel you can squeeze in after a heavy venting session ? I have heard 50 litres but want to be safe.

Really want to crack the 500 mile range barrier.

Don't know the exact figures but I also heard 50/52 ltrs. I do belive tempreture also has an effect. A real frosty morning is worth a few litres.......

why vent? do a search for "ventectomy" - quick easy and I've been running with it for a year now, no probs

I still need to get this sorted out one day, would save me a lot of frustration for sure

i've got over 52 litres in and could of put more in but the pump at the garage times itself out and shuts off , i can do well over 600 miles with a light foot with that amount of fuel

If I manage to make TRAX this year again, I'll do a ventectomy for your Fabia vRS, WW. Did Xav's vRS last year in about 5 mins.....

Be really cool to say I've "worked on" two of the most tuned cars on Brisk!

I'm not gonna be driving at TRAX myself but when you're in the UK, definitely drop me a line and unless I'm not in the UK, I'll find a way to meet up

Rubbish ! :confused:

The co-efficient of expansion (or contraction) of diesel which is (per degree C) only 0.00108 means that for every degree drop in temperature you would actually be able to put just 0.00108% more diesel in your tank. But even with a hard frost and a 50 litre tank in the real world you are talking about virtually no measurable difference in the amount of fuel you could put in your tank !

Last weekend I achieved my best MPG so far with my bog standard Fabia vRS.Driving to Stansted and back with the cruise control set on 70mph the car managed 53 MPG.I'm curious to see if a similar journey would be even more economical at say 65 mph,but I'm not sure if I have the willpower to drive along being passed by every Tom **** and Harry.

Aha! Thanks....will look for that now.

Having said that, does the extra fuel give a noticable weight difference? As in makig the car feel a bit more sluggish hauling all that juice around?

All it takes is one passenger and my car feels slower.....noticably so. I pray for cold air when I've got passengers.

I was actually talking of a 6,000,000,000, litre tank, I just forgot to mention it....

That'll be as fitted to the "long range" VRS" model then !

Nahh !

You're only looking at about an extra 7 litres or so of fuel which doesn't weigh very much at all but it could give you an extra 70 or 80 miles range from your tank.

It's one of the easiest mods to do as well, see HERE!

LOL. Righto.

Thanks mate.

Don't forget that some warmed-up derv is constantly being returned to the main tank.

If it's near-empty and you fill up, you notice the car is more "perky" (nice word there huh? ) because of all the cool fuel. Better to be more-full than more-empty I think - the fuel temps stay a bit lower IMHO.....

See the thread linked to above - we've discussed it pretty deeply, touching on performance, economy, range, and even touching on the meaning of life....

Cheers

Bas

Is warmed up derv not better for combustion? :confused:

Chris

I'm still not convinced with all this brim filling malarky... all you're doing is reducing the number of times you fill up - which means you never get to buy cans of red bull, ginsters steak slices or M&M brownies!!

MPG isn't going to be affected as you're getting more miles from more gallons.

what's the "normal" capacity of the tank ?

Right but this mod just means that you effectively have a larger fuel tank and therefore more range/less fuel stops. Plus if you watch prices and they do vary quite abit (?) you can fill up more cheaply when it suits you, not being forced by having an near-empty tank...

It's a neat mod, or pretty useless depending on how you look at it....

Personally, I hate wasting time filling up. Having an extra day or two before needing to stop for fuel does save me time.

Bas

what's the "normal" capacity of the tank ?

45 litres.

I've managed to get 52 litres in before.

Normally the light comes on with 7 litres left out of the 45 litre tank. Means you're whacking in 38 litres to a normal fill up which comes to about £34 round my area.

I personally love the fact the fuel tank is diddy as it feels good to spend so little each time I fill up (the previous car was £50 a week compared to the £34 I spend now). It's psychological. I spend less each time and fill up just as often.

If I was to do this mod I'd fill up less often but spend more each time. It wouldn't feel as good even though it's exactly the same.

For lots of short town journeys for example there's very little point as most of the cars energy goes into picking up speed from being stationary. Having a tank laden with fuel increases inertia and thus requires more energy to get moving which reduces mpg. But on long runs or people commuting it's ideal as you spend most of the time rolling and the extra sprung weight would not really be noticed.

It depends on how you look at it really.
