stripy Posted May 17, 2006 Share Posted May 17, 2006 what sort of max psi or bar should i be looking for on a 200tdi defender without doing head gaskets or running hot on the turbo that is cheers john Quote Link to comment Share on other sites More sharing options...
Tonk Posted May 17, 2006 Share Posted May 17, 2006 mine runs about 1.1, bit below that is probably better unless u like rebuilding engines Quote Link to comment Share on other sites More sharing options...

simonb Posted May 17, 2006 Share Posted May 17, 2006 200Tdi in a defender is about 0.8-0.85, 300Tdi is 1.05 bar. Wasn't aware of any difference between defender and disco. Several people on here run 200Tdi defenders at 1.05/1.1 without any problems but it does depend if the injection pump has been tweaked (more boost and more fuel means higher EGT....) With standard fuelling 1.1 should be ok. Quote Link to comment Share on other sites More sharing options...
white90 Posted May 17, 2006 Share Posted May 17, 2006 The Disco Auto runs higher boost IIRC I'm running 1.25 and was using 1.5 for over a year Alisport i/c fitted and pump adjusted goes ok but 20mpg or worse Quote Link to comment Share on other sites More sharing options...
stripy Posted May 17, 2006 Author Share Posted May 17, 2006 i should have said that i'm runing a larger intercooler and the pump has had the full tweek treatment ie diaphram,star wheel ect ect Quote Link to comment Share on other sites More sharing options...

will_warne Posted May 17, 2006 Share Posted May 17, 2006 1.25-1.5 max IMHO thenand get an EGT gauge before trouble sets in The TGV runs 1.3 bar as standard on overboost; 1 bar normally. Quote Link to comment Share on other sites More sharing options...
honitonhobbit Posted May 17, 2006 Share Posted May 17, 2006 I run just over 1 bar with a mahusive Alisport 'cooler and tweaked pump, it's a Disco lump rather than a Defender lump. It runs a snadge over 150bhp and 270ft/lb. Oil flow to the turbo has been improved. I get an avergae 0f 33mpg but can get 37mpg if I pootle.

stripy Posted May 17, 2006 Author Share Posted May 17, 2006 what is an EGT gauge & how is it plumed in , oh and what should it read...............sooooo many questions Quote Link to comment Share on other sites More sharing options...
honitonhobbit Posted May 17, 2006 Share Posted May 17, 2006 An exhaust gas temperature guage plumb it in a bit like a Lambda sensor waste of time but looks good, they where a bit of a 'must have' accessory a while back but it is much easier to use a SUN diesel tuner/rolling road and set it up properly the first time as EGT can be measured then and there OR if you talk to Andy Walker at Alisport and follow his instructions to the letter you will have no problems. If you get your pre boost fueling/post boost fueling/air flow wrong it will up your EGT a bit like a petrol engine that is badly tuned, will get hotter. If you cane the ar*e of a tuned diesel it will run hotter anyway, the idea behind tuning is to reduce the gear changes and make driving easier. 200Tdi's respond better to tuning than 300Tdi's, don't know why, they just do. I run both and I work with both, in the long run I prefer the 200 but it is only marginally better than the 300. Both my Tdi's run bigger coolers and have pump tweaking... Oddly enough the 300 seems to respond better than the 200 to exhaust mods. A 300 with a 200 turbo runs the same as before as long as you tweak the boost.

Bull Bar Cowboy Posted May 17, 2006 Share Posted May 17, 2006 20mpg or worse 20mpg ………. I would be over the moon with that Since I keep stuffing ponies into the motor ………….. 16mpg if I drive carefully (65/70) …………14mpg if I am in a hurry (80+) …………. 12mpg if I drive it real hard …………and 6 – 8 mpg in low box off road ……….but of course, this is a real engine, 8 cylinders of petrolhead porn ………….. and no boost needed, for 200 ponies .........none of yer 4 pot deep fat fryers here ya know ….

stripy Posted May 17, 2006 Author Share Posted May 17, 2006 Hmm all tweeks done by myself being a tight skint sort of bloke , i have tweeked to the max and it go's like stink, but i think i need to know what how hot the exhaust gasses are before she blows ( again ) does this look about right sensible-570c hot-682c limit-720c EGT guages arnt cheap are they not even any on e-bay Quote Link to comment Share on other sites More sharing options...
honitonhobbit Posted May 17, 2006 Share Posted May 17, 2006 When you say tweaked to the max what do you mean? What did you do? BTW the 200Tdi/300Tdi turbos are very crude and will not run high boost for long without going pop. About 18psi is the limit and will still shorten turbo life. I wll try and dig out what my EGT levels were, but Les B and Tony C both run on board EGT guages Quote Link to comment Share on other sites More sharing options...
stripy Posted May 17, 2006 Author Share Posted May 17, 2006 my set up at the moment is double depth intercooler, turbo i think is about 12 psi . the pump has been set to the max as per here http://www.dodgeram.org/tech/dsl/more_power/Power_ve.htm thanks for all the help so far i need to get it sorted befor i tow my heavy caravan around 1000mls Quote Link to comment Share on other sites More sharing options...
honitonhobbit Posted May 17, 2006 Share Posted May 17, 2006 http://www.britishmetrics.com/html/pis-bar.htm for Bar/psi calcs 12 psi is about standard for a 200Tdi Have you inverted the diaphragm? Quote Link to comment Share on other sites More sharing options...
stripy Posted May 17, 2006 Author Share Posted May 17, 2006 i need to check the boost pressure it was up'ed when the intercooler was fitted so i'm not realy sure no the diaphram was only turned . what does inverting it do Quote Link to comment Share on other sites More sharing options...
BogMonster Posted May 17, 2006 Share Posted May 17, 2006 There is info in the tech archive about fitting EGT gauge if anybody is interested Thermoguard EGT Gauge EGT Response Times thread Max EGT I have registered since fitting is 618*C (std fuelling, std intercooler) but rarely goes much above 550 unless you are caning it flat out up a long hill Must get around to that Allisport intercooler one of these days Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted May 17, 2006 Share Posted May 17, 2006 good god Kin Hell You Lucky lucky ******* I dream of 20 mpg, the best I managed was a tank (ok the V8 was being "fully enjoyed") and I filled up 55 litres in erm ................less than 90 miles Nige And "yes" - its even worse off road Quote Link to comment Share on other sites More sharing options...
Gromit Posted May 18, 2006 Share Posted May 18, 2006 why kind of cost is involved fitting an EGT kit? I didn't see any display suppliers listed on those links. Quote Link to comment Share on other sites More sharing options...
Tonk Posted May 18, 2006 Share Posted May 18, 2006 egt can be easily fitted yourself, its normaly a probe into the exhaust manifold which just runs a guage Quote Link to comment Share on other sites More sharing options...
Gromit Posted May 18, 2006 Share Posted May 18, 2006 egt can be easily fitted yourself, its normaly a probe into the exhaust manifold which just runs a guage sorry, yes, meant the price of parts. ETG looks to be about 30 quid. How much do the digital gauges run to? Quote Link to comment Share on other sites More sharing options...
