Jasesapphy Posted December 10, 2012 Report Share Posted December 10, 2012 Hi Guys This weekend I have done some testing on air charge temps, and was quite suprised just how high they are getting on the 330d, actually i am going start looking for an intercooler upgrade (hopefully less than the £450 option from Allard) The car is ok when driving normally but soon as you start opening up and pushing on some of themp are climbing very high. It should be a consideration for you all. Quote Link to comment Share on other sites More sharing options...
autosri Posted December 10, 2012 Report Share Posted December 10, 2012 Meth/water injection maybe Quote Link to comment Share on other sites More sharing options...
Jasesapphy Posted December 10, 2012 Author Report Share Posted December 10, 2012 Bigger intercooler i reckon best option for ease, could use meth/water, we did this on old track car A decent intercooler will significantly reduce temps, the 330d ones arnt very big TBH Quote Link to comment Share on other sites More sharing options...
autosri Posted December 10, 2012 Report Share Posted December 10, 2012 What sort of temps are you getting then out of interest Quote Link to comment Share on other sites More sharing options...
Jasesapphy Posted December 10, 2012 Author Report Share Posted December 10, 2012 Going to get some more peak readings but 98oC was seen the weekend, which is bloody high Quote Link to comment Share on other sites More sharing options...
autosri Posted December 10, 2012 Report Share Posted December 10, 2012 Wow that's pretty warm you must be able to gain some power by dropping that down Quote Link to comment Share on other sites More sharing options...
L333JSA Posted December 10, 2012 Report Share Posted December 10, 2012 98degrees is nuts. Where were you recording this from out of interest? I've got a fairly sizeable intercooler to go on next. Quote Link to comment Share on other sites More sharing options...
james@ M Developments Posted December 11, 2012 Report Share Posted December 11, 2012 Crazy isn't it, you can literally touch the outlet side if the std cooler and think my god! How hot! That's why the cooler I developed had to be very efficient and make the most of the space we had to play with Quote Link to comment Share on other sites More sharing options...
Jasesapphy Posted December 11, 2012 Author Report Share Posted December 11, 2012 James does it fit with the fan there? Allard one replaces big fan with 2 small ones Quote Link to comment Share on other sites More sharing options...
james@ M Developments Posted December 11, 2012 Report Share Posted December 11, 2012 (edited) I'm sure the same could be done with ours, just use two smaller slimline fans, I need a car to try as mine didn't have them fitted Edited December 11, 2012 by james@msd Quote Link to comment Share on other sites More sharing options...
dannyboy759 Posted December 22, 2012 Report Share Posted December 22, 2012 Was the temp taken from the alloy part of the charge cooler hoses where the OEM temp sensor sits? This would be open to heat soak from the rest of the engine and doesnt give an accurate reading! Quote Link to comment Share on other sites More sharing options...
L333JSA Posted December 22, 2012 Report Share Posted December 22, 2012 Let's be honest here........BMW wouldn't of put an air temperature sensor in a charge pipe that was going to read inaccurately now are they!? All the charge system will suffer from heat soak but that's only when you're sat in traffic, However a good intercooler will soon get these temps down as you start moving again, Quote Link to comment Share on other sites More sharing options...

L333JSA Posted December 27, 2012 Report Share Posted December 27, 2012 Thats my charge temps sorted. Quote Link to comment Share on other sites More sharing options...
dannyboy759 Posted December 28, 2012 Report Share Posted December 28, 2012 Looks pretty good What was that off off? And whats your thoughts on increasing the lag with the larger cooler? Quote Link to comment Share on other sites More sharing options...
L333JSA Posted December 29, 2012 Report Share Posted December 29, 2012 It was originally an Airtec 70mm RS500 Cosworth Intercooler that I had modified - basically the top chopped off it and smaller inlet/outlets welded on. No extra 'lag' at all - bear in mind all you are doing is just compressing the air that's already in there. Quote Link to comment Share on other sites More sharing options...

No extra 'lag' at all - bear in mind all you are doing is just compressing the air that's already in there. Oh right a custom job then?! nice If you increase the "space" or size of a charge cooler you do run the risk of lag due to the cooler cooling the air arfter the turbocharger has compressed it. It can also be a problem if you move the cooler for any reason and extend the piping to and from it, getting more surface area is always a good thing but it will increase lag, just depends on how much and if its noticable or not!

Jay Cartay Posted May 21, 2013 Report Share Posted May 21, 2013 Sorry to drag this up but was the airtec cooler fitted with a fan/fans in the end? Quote Link to comment Share on other sites More sharing options...
L333JSA Posted May 21, 2013 Report Share Posted May 21, 2013 Without. Quote Link to comment Share on other sites More sharing options...
Jay Cartay Posted May 21, 2013 Report Share Posted May 21, 2013 Any repercussions of doing that? Did Jasesapphy have to fit his without? Quote Link to comment Share on other sites More sharing options...
L333JSA Posted May 21, 2013 Report Share Posted May 21, 2013 Non whatsoever that I have found anyway. My intercooler is different to Jasesapphy's Quote Link to comment Share on other sites More sharing options...
Jay Cartay Posted May 21, 2013 Report Share Posted May 21, 2013 I'm worried that the fan is there for a reason and that removing it must be bad lol. Quote Link to comment Share on other sites More sharing options...
L333JSA Posted May 21, 2013 Report Share Posted May 21, 2013 The only thing its going to possibly going to affect is the aircon when stationary I believe. Mine's been off for 4 months ish and I know of someone elses thats been off for over a year with no adverse affects. Quote Link to comment Share on other sites More sharing options...
Jay Cartay Posted May 21, 2013 Report Share Posted May 21, 2013 Ah. I do like to use my aircon. Hmm..... More thought required.... Quote Link to comment Share on other sites More sharing options...
