Sigi_H Posted November 18, 2020 Share Posted November 18, 2020 It is said, that a decrease of intake temp of 5°C makes minus 50°C EGT. Don't know, if it's right, but plausible. Intercooling is important Quote Link to comment Share on other sites More sharing options...

Glad the boost controller has made it easier, Chambo. How does it drive now ? You still have the fuel pin fitted ? For others following, the mumby controller on ebay is of a suitably agricultural design to fit right in under a Defender bonnet 🤣🤣 Mo Yep steggys pin still fitted. Goes well I think. Other than a little puff on start up I haven’t noticed any big black or white clouds behind me. might have to get the wife out to observe though as when going forwards at speed I prefer to look the same direction cheers Quote Link to comment Share on other sites More sharing options...

Intercooling is important Interesting - so if the intercooler cant cool more then the temp introduced by compressing then you may do more harm than good by increasing boost... I wonder where the sweet spot lies with the standard setup - i.e. is the 0.85 bar it for the factory 200tdi or was there a fair bit of leeway on that?

Sigi_H Posted November 18, 2020 Share Posted November 18, 2020 The conclusion is: If you increase boost, use a bigger intercooler as well. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted November 18, 2020 Share Posted November 18, 2020 Or test, don't guess. If I remember rightly, Daan's testing said that the stock intercooler was really very good indeed. 1 Quote Link to comment Share on other sites More sharing options...
Sigi_H Posted November 18, 2020 Share Posted November 18, 2020 I use the Allisport Double Core For hard conditions I think about water spraying on it. Easy to build, good effect and fits good in place. Maybe I use the wind screen washer bottle too Quote Link to comment Share on other sites More sharing options...
Jocklandjohn Posted October 2, 2021 Share Posted October 2, 2021 On 11/12/2020 at 2:20 PM, Mo Murphy said: Leave the rod length standard and use a manual boost controller to adjust your boost pressure. Much easier to get at and simple to fit. Shortening the rod is so last year. Mo Just came across this thread (missed it previously) and its very interesting! Where did you get this controller Mo? Are they engine-specific or one-size-fits-all? Seems like a more civilised way to adjust/manage boost than with the threaded rod which has an inherent desire to destroy your finger nails!

Peaklander Posted October 2, 2021 Share Posted October 2, 2021 Yes that’s the one I got and it was recommended by @Mo Murphy I think. Mine is a 300 TDi and I fiddled until I got about 1.1 / 1.2 Bar and have left it alone since. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted October 2, 2021 Share Posted October 2, 2021 That's the one I use John, it's design is suitably agricultural to fit in with the 200tdi 😁 Mo Quote Link to comment Share on other sites More sharing options...

Thanks for the confirmation. I think thats a really useful thing. And its NOT what I thought - some uselessly elaborate and complicated device - rather a very simple and elegant solution to a right old faff!

Mo Murphy Posted October 2, 2021 Share Posted October 2, 2021 I don't do complicated or elaborate. That's why I have a 200 Tdi 😁 Mo 1 Quote Link to comment Share on other sites More sharing options...
