osso Posted February 2, 2004 Share Posted February 2, 2004 Hi all, Now that i have got the EGT sensor installed to the 1st port on the manifold and here are the readings for a completely standard j-spec soop Idle @ 320 ~ 400 C normal cruising varies from anywhere to 500 and 700 C max boost at 0.85 bar 790 C i am assuming this is all perfectly normal for a completely standard j-spec soop.. obviously i am planning to do a full decat soon and expect the temps to drop, i dont know how much will the EGT temps will drop when the cats are removed, im guessing around 50C ~ 80C I am also assuming that a FMIC will drop the temps further.

Kevin Huntley Posted February 2, 2004 Share Posted February 2, 2004 I think you will find the opposite is true, once you remove the cats your EGT's will increase due to the increased boost you are running. My EGT'S have bee as high as 920 on a hot day at 1.35 bar boost even with an intercooler and water injection. Cheers Kevin Quote Link to comment Share on other sites More sharing options...

osso Posted February 2, 2004 Author Share Posted February 2, 2004 running at 920C sounds V dodgy!!! Quote Link to comment Share on other sites More sharing options...
Dragonball Posted February 2, 2004 Share Posted February 2, 2004 Originally posted by osso running at 920C sounds V dodgy!!! Check out the search button on these figures James 920 is fine - anything over a thousand = not good Before my FMIC I was hitting 980 on a hot day! But the EGT is the PITA gauge - and you can ruin you life by the thing! Quote Link to comment Share on other sites More sharing options...
osso Posted February 2, 2004 Author Share Posted February 2, 2004 :O running at 980 is seriously pushing the engine to the limit! the great thing about the defi gauges you can set the warning limit to any value you wish, say 850, when that limit is hit a red light will come on, so you dont have to keep an eye on the EGT gauge all the time the peak button is pretty useful too!

heckler Posted February 2, 2004 Share Posted February 2, 2004 with my cats fitted (0.9 bar) - the EGT never got above 820 degs.. cats removed - hit 1.45bar and 920 degs... Quote Link to comment Share on other sites More sharing options...
dandan Posted February 2, 2004 Share Posted February 2, 2004 Yes but at the same boost with the cats out you'd be cooler than with cats in. Dan Quote Link to comment Share on other sites More sharing options...

Dan Agree I seem to remember that CW mentioned that anything upto 950C is fine. Not for long periods of time mind Quote Link to comment Share on other sites More sharing options...
Ian C Posted February 2, 2004 Share Posted February 2, 2004 900 is good, nice and efficient. 950 is as high as you'd want to see under any circumstances other than a drag race. Anything into four figures is trouble. It also depends on where the probe is, it's gotta be on the manifold somewhere rather than after the turbo, but if you were reading 900degC after the turbo it's probably on fire -Ian Quote Link to comment Share on other sites More sharing options...
Darren Posted February 3, 2004 Share Posted February 3, 2004 Mine runs at 1200-1400! Hopefully I'm running in F rather than C. Anyone? Quote Link to comment Share on other sites More sharing options...
