lupo_1.0 Posted October 9, 2004 Report Share Posted October 9, 2004 what is the best mod(s) to get for more performance. i only got a 1.0.cheerschris Quote Link to comment Share on other sites More sharing options...
one litre wonder ;) Posted October 10, 2004 Report Share Posted October 10, 2004 i have a one litre as well ( not like the name dont give it away ) but i would say the best mod for more power is a nice and easy 1.8 litre turbo lump put under the bonet as u aint gonna get much power out of the mighty one litre lump Quote Link to comment Share on other sites More sharing options...
lupo_1.0 Posted October 10, 2004 Author Report Share Posted October 10, 2004 i have got something like that as a idea but i ment for the time being and for cheap Quote Link to comment Share on other sites More sharing options...
payna Posted October 10, 2004 Report Share Posted October 10, 2004 i would reckon an induction kit is always a good place to start, iam not up to speed with what is available for the little 1 litre but no noubt tigz will be able to help you out! :wink: Quote Link to comment Share on other sites More sharing options...
Arvid Posted October 11, 2004 Report Share Posted October 11, 2004 I think that the best mod you can make is save your money for a 1.4, because mods on a 1.0 can be expensive and give relatively very little performance gains :-( Quote Link to comment Share on other sites More sharing options...
Tigz™ Posted October 11, 2004 Report Share Posted October 11, 2004 Id have to agree mate.There is supposed to be a chip avalable but there is no proven figures to back up the claims.Ive fitted a exhaust which removes one silencer and replaces the centre on with a much smaller unit, and although this has improved throttle responce, low end touque has been lost, so I wouldnt recomend it.Everyone I know with a 1 litre who has fitted a induction kit has lost power also.Although I am concidering adapting a BMC filter to see if that gives any increace.Id very much doubt it though!

Arvid Posted October 11, 2004 Report Share Posted October 11, 2004 a lot of cars lose power when they have an inductionkit. I've heard and also experienced in my bussiness that in most cases a panel performance replacement filter works much beter in not losing power and still have improved throttle response. My first mod back then was a K&N panel filter wich seemed to work just fine. Quote Link to comment Share on other sites More sharing options...
Jabo Posted October 11, 2004 Report Share Posted October 11, 2004 Arvid, have you got any experience with cylindrical BMC replacement filter element for 1.4TDi? Quote Link to comment Share on other sites More sharing options...
Tigz™ Posted October 11, 2004 Report Share Posted October 11, 2004 A filter upgrade on a Deisal engine is a waste of time isnt it? Quote Link to comment Share on other sites More sharing options...
Arvid Posted October 11, 2004 Report Share Posted October 11, 2004 as far as i know a diesel will improve only very little, and the bmc isn't cheap. Quote Link to comment Share on other sites More sharing options...
Jabo Posted October 11, 2004 Report Share Posted October 11, 2004 QUOTE(Tigz)A filter upgrade on a Deisal engine is a waste of time isnt it?1. Am i right in thinking that reducing restrictivness of air admissin system improves torque and power (by small margin power by larger trque, especially at low rpm end)?2. If the above is true and BMC test figures are right then fitting mcuh lower restriction BMC filer replacement element would cause the effect described in (1) - acc to BMC, if I remember correctly, if 100% is no filter at all, 65% is new paper filter then BMC oiled cotton gauze is 85%.But then again, I stumbled across this one http://www.bmcairfilters.com/VisDyno.asp - check Polo 1.6GTi dyno test results...EDIT: removed misinterpretation of the graph style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" /> Quote Link to comment Share on other sites More sharing options...
tdwindustries Posted October 11, 2004 Report Share Posted October 11, 2004 Umm right. The engine will give more power when it can breathe more easily. An exhaust which allows more out, (inc. manifolds and `de-cat`) will mean air can get out fast. You then want to increase COLD air in so you can fit a filter or a whole new airbox (induction kit) to improve air flow. The BMC is sealed so it keeps out (as much as possible) engine heat, other induction kits are not sealed and they allow HOT air from the engine to be sucked in - resulting in loss of power.The BMC website shows torque AND BHP - there are two seperate lines. The dotted line is WITH the BMC and the solid is without, so power is increased across the range with a BMC. Quote Link to comment Share on other sites More sharing options...

Snoopy Posted October 11, 2004 Report Share Posted October 11, 2004 QUOTE(tdwindustries)An exhaust which allows more out, (inc. manifolds and `de-cat`) will mean air can get out fast.Ask Tigz about that - his exhaust was very unrestrictive, and he suffered a loss in power.I also believe there is some caveat regarding exhaust `back-pressure` and turbos, but Blackrat is your man to speak to about that.

Tigz™ Posted October 11, 2004 Report Share Posted October 11, 2004 Yes its the loss in back pressure that has caused me problems.I dont belive its power loss thats the problem, its more of a touque loss.There is a lot more power top end, but from 3.5krpm down the engine is lifeless.

tdwindustries Posted October 11, 2004 Report Share Posted October 11, 2004 ah yes well obviously you can go to much I was merely tickling the subject to answer the enquirers intial line of enquiry. the basics are easy - more air in + more air out = more power but I didnt say there werent caveats. In fact i think remus or somebody has a full description on their web site I will have a look Quote Link to comment Share on other sites More sharing options...
tdwindustries Posted October 11, 2004 Report Share Posted October 11, 2004 well this is pretty good:Let air come in more easily - As a piston moves down in the intake stroke, air resistance can rob power from the engine. Some newer cars are using polished intake manifolds to eliminate air resistance there. Bigger air filters and reduced intake piping can also improve air flow. Let exhaust exit more easily - If air resistance or `back-pressure` makes it hard for exhaust to exit a cylinder, it robs the engine of power. If the exhaust pipe is too small or the muffler has a lot of air resistance then this can cause `back-pressure`. `High-performance` exhaust systems use headers, big tail pipes and `free-flowing` mufflers to eliminate `back-pressure` in the exhaust system.

Jabo Posted October 12, 2004 Report Share Posted October 12, 2004 The only reason I can think of (i did some reading recently but by no means I know the subject) there is an oxygen probe just before the cat and after the cat. If you remove your cat the first one is getting lower pressure exhaust and what follows lower oxygen readings at low revs and ECU adjusts fuelling accordingly.That's just my thinking, I bet it is not as simple as that since there are many more sensor readingto take into account Quote Link to comment Share on other sites More sharing options...
tdwindustries Posted October 12, 2004 Report Share Posted October 12, 2004 yeah not sure what they do but if you decat then you also `de-sensor`!ask ross (red lupo gti) he has no cat or pre cat Quote Link to comment Share on other sites More sharing options...
Snoopy Posted October 12, 2004 Report Share Posted October 12, 2004 There are issues. And not just with fault codes. I'm convinced Ross has been very lucky - modern VAG ECUs almost always develop rough running and lowered performance shortly after they've been decatted.

Jabo Posted October 12, 2004 Report Share Posted October 12, 2004 Were sensors totally removed/disconnected?When I was thinking exhaust I was looking for performance catalysts with min 85% free cross sectional area (65% is max with stock types afaik) Quote Link to comment Share on other sites More sharing options...
Red Lup Gti Posted October 12, 2004 Report Share Posted October 12, 2004 I still have sensors were they should be just not cat or `pre-cat`.it runs well on tickover and i havnt felt any ill effects of having it `de-catted`.It still puts real well and can near enough get it reading off of speedo when trying hard ( private road) when i do have warning light turned off i doesn't make any diffrence at all.Clifford r in process of making tubular manifold for it so that should be entertaining??!!

Jabo Posted October 12, 2004 Report Share Posted October 12, 2004 He he he he, gotta wait for the warranty to run out, then I `de-cat` it, install permamently 2nd stage inter and custom tune the chip (or even buy uprated ECU)EDIT:Previous post got edited and this one does not make any sense now :? :roll: Imho if you make serious mods to your car it only makes then perfect sense to have your ECU tables retuned to your new setup. I suppose that if you had it custom retuned then you'd see some more difference style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> Quote Link to comment Share on other sites More sharing options...
arosa_chris Posted October 18, 2004 Report Share Posted October 18, 2004 i'm in the exact same boat as lupo_1.0 lad so i know the feelin. due to the numerous reasons you are unable to get that much wanted more powerful motor at this point in time, you desperately want 2 do something you are able to at this present time. i think the best option is to do what i have done and accept the fact you are going to get unnoticable powergains at best from a 1.0litre lump (especially being that you are looking for the 'cheapist mod'). get an induction kit and exhaust and this will make your car at least sound as if its packin somethin a bit beasty under the bonnet. hope that helps Quote Link to comment Share on other sites More sharing options...
Jabo Posted October 18, 2004 Report Share Posted October 18, 2004 Spent £400-£600 on NoS kit and you WILL get more power instantly style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> Quote Link to comment Share on other sites More sharing options...
