Fuel economy

[Wayne]

Davies, Tuning box,, How much does that set you back and what does it bump the power to ?? ish ..

Tuning boxes are a waste of time, all they tend to do is run the cold start map and dump loads of extra fuel, a proper remap is a much better bet.

If you looking for cheap to run then forget a GTI and look at TDI's or a 1.4 Polo.

one small problem with the logic you have just said nearly all tdis that i know of that are in the mk3s all run the same ecu which controsl a mechanical pump which has an electronic head put o and the ecu that they use is not one that is chippable unless you solder an eprom in then get that flash mapped, only problem with this is it has minimal mapping possiblities and no one i can find will do it in the uk and trust me iv looked the only place is america, i know all this as im doing my uni project on it and thats why iv gone for a hybrid mechanical tdi conversion with a 12mm head in allowing over 250 horse

I am sure you can get them remap / chipped, superchips use do them.

As for 250bhp  sorry but cannot see you getting anywhere close to that figure.

no offence mate but if you have read as much as me and the fact i do motorsport engineering at uni, it is very possible that couple with the fact i have russ fellowes intake and exhaust manifolds oh and a a gt25bb turbo plus that the guy iv bought a couple of bits of diesel bob tuning in ribchester has used the same setup and it produced 250 brake so its more than possible! thats at 2.2bar of boost

So after all that what mpg will end up.

Interesting you say that it is possible yet VW needed to do major work with PD to get 150bhp.

[Agreeable Slick]

The tuning box on the pump will just over-ride the electronic governor meaning it won't govern the amount of fuel going in to the engine.

Oh and using bio fuel long term and high concentration (i.e. B50 or higher) is not such a hot idea as the old mechanical pumps does not have the seals package that is designed to allow biofuel running. Would keep an eye on all of the seals in the fuel system if I was you bud.

id look into that mate on tdiclub.com  seeing as what is the difference between a 115bhp pd and a 150?? oh thats right internally nothing its got a larger turbo front mounted intercooler freer flowing inlet larger injectors to allow more flow and a different map and if you look up a pd engine they can take 400 bhp on standard internals

if youd like to ring diesel BOB tuning in preston im pretty sure he has more knowledge than me or you and he will tell you that 250bhp is achievable itll cost 2 grand plus which i have already spent

dont need to worry my pump has just been reubilt and had different seals fitted so it can run 100% if wanted but obviously only in summer

So to answer my question say you get 250bhp out of it what mpg will you get.

lets get this right mate you started having a go first mate i answered a thread question and to answer your question id still prob see 26mpg which is only when i hit boost as the engines performance is geared to 100bgp normally unless on boost, 26 is more than you boys get
