Vaughany Posted February 25, 2005 Share Posted February 25, 2005 I am looking to purchase a EGT Guage so I can better monitor the safety of the vehicle. I have been looking at MVP, all of their guages come with the necessary wires and sensor. Is there anything else required for fitting etc (Not Pillar Pods) and where exactly do you place the sensor. Thanks Quote Link to comment Share on other sites More sharing options...
merckx Posted February 25, 2005 Share Posted February 25, 2005 and where exactly do you place the sensor. Thanks In the exhaust manifold, as close as possible to the exhaust port. If you do a search there is plenty to be found on the subject. Quote Link to comment Share on other sites More sharing options...
LeeT Posted February 25, 2005 Share Posted February 25, 2005 in the exhaust runner nearest the front of the engine bay. i still havent got round to fitting mine and the gauge has been in the car for over 6 months now. may as well just wait till i go single now Quote Link to comment Share on other sites More sharing options...

The exhaust mainfold is the most acurate point for temperature, but there is a small chance that if the probe tip should break it will end up in the turbo. There is a second position (but I cant remeber where it is...someone will be along to tell you)...this position is much safer but the reading is not so acurate due to thermal lag (about 200C difference) Quote Link to comment Share on other sites More sharing options...

paul mac Posted February 26, 2005 Share Posted February 26, 2005 there was a vast thread on the subject of hottest cylinder and the conclusion was they were all basically the same, from what i've read about engines, on a straight six the middle cylinders could potentialy be the hottest but if CW puts them in the first cylinder thats good enough for me Quote Link to comment Share on other sites More sharing options...
foodfreak Posted February 26, 2005 Share Posted February 26, 2005 Both Terry s & I have had tips break off, it's the main reason I went single. would not use a EGT again Go for a AF/R gauge instead, much more accurate & faster respnding. Just slightly more expensive John Quote Link to comment Share on other sites More sharing options...
terribleturner Posted February 27, 2005 Share Posted February 27, 2005 Im getting my EGt installed in a couple of weeks. But what do you think about i going into the downpipe and not into the manifold?? Quote Link to comment Share on other sites More sharing options...
TLicense Posted February 28, 2005 Share Posted February 28, 2005 The further away from the exhaust valve you put the probe the slower reacting, and inaccurate reading you'll get of true exhaust temps. Simple as that really. The tip breakage issue is a risk. (Hmm, kind of paradoxical really, do you run the risk of high EGT temps and melted pistons/exhaust valves or do you fit an EGT probe and run the risk of the tip letting go and saying goodbye to the turbo??? - Which ever's cheapest I presume!)

paul mac Posted February 28, 2005 Share Posted February 28, 2005 Both Terry s & I have had tips break off, it's the main reason I went single. would not use a EGT again which egt gauge/probe were you using at the time and how long had the probe been in from new, i'me a bit worried now Quote Link to comment Share on other sites More sharing options...
foodfreak Posted February 28, 2005 Share Posted February 28, 2005 Mine was a Greddy probe, not sure which one terry had let go:( Quote Link to comment Share on other sites More sharing options...
paul mac Posted February 28, 2005 Share Posted February 28, 2005 Mine was a Greddy probe, not sure which one terry had let go:( how old was it mate, i might be a bit pro-active and replace mine just wondered on the life span Quote Link to comment Share on other sites More sharing options...

paul mac Posted March 1, 2005 Share Posted March 1, 2005 It was only 9 months old:( thanks for that mate i was thinking of changing mine every 6 months and that confirms my suspicions, as you said i might go the whole hog and get a wideband, how much damage did the probe do when it let go ?

foodfreak Posted March 1, 2005 Share Posted March 1, 2005 Completely shagged 1st turbo, blades, & bearing within 1 second........... f****ng great plume of smoke, ask Dude how bad it was. if you remember the days of F1 turbos letting go ,....... That was mine:( Quote Link to comment Share on other sites More sharing options...
Ian C Posted March 1, 2005 Share Posted March 1, 2005 I'm gonna get mine put in the collector so that if it breaks it'll head off through the wastegate and straight to atmo Shouldn't be a massive temperature differential between there and the exit of the cylinder head, and it's for monitoring purposes, not tuning, so accurate to 50degC is good enough for me. -Ian Quote Link to comment Share on other sites More sharing options...
paul mac Posted March 1, 2005 Share Posted March 1, 2005 wow, well thats settled then wideband it is, anyone want to buy a second hand egt gauge Quote Link to comment Share on other sites More sharing options...
