ive an EGT guage , v.handy and yes it normally goes to that level on the peak hold :lol: :lol:
From what I was reading before, max EGT before detting is specific to each engine. In that one may take 1000C where another won't. A decent mapper will be able to tell you at what EGT your engine is starting to det as long as he's monitoring EGT. I'd say it would be best he can tell you the temp on an in car gauge tho as his (if he has one) may be reading different to the one in the car.

It all depends where the EGT probe is placed in the exhaust. Mine is in the exhaust housing of the turbo which is one of the hottest places so anything up to 1000c is ok but anything past that and back off.
Where is your EGT probe placed??

like you on the most high temperature point,
but this morning I have take a 1123 °c ! :?
it's time ti put off the Gr.N restrictor but its not as simple as I have believe :
1str the lead
the pipe
the Fan
We got it
its not very very exact measure but the problem is that GrN impose to reduce turbo air intake about 30 mm and to do the same work my Turbo is doing more job.
And it will give me more power but I wiil find a mann who can remake this part with good value.
I will check next week
this is the problem

Just buy a new compressor inlet from Nissan-they are 53mm I think.Or you can buy a larger alloy on from APturbos.

My car is an EX semi-official Nissan RAlly CAR,:
and for this reason they are forced to put a restrictor to be OK with FIA
It's the same thing for alle the Gr N rally Car !
this car is 300 Hp with this Restrictor:
without I will win Hp and reduce my EGT temp !!
2 good reason to put it off !
But I need to remake this parts, I had go to Nissan this morning here in France they can't sell only this piping, I will see next week with one of my father friend who make parts for Rally car !! to have 50 or 53 mm everywhere into the pipe !
( excuse my english not easy to explain) :?

according to the mann who made this car, the ECU can go higer, from 1.0 to 1.8 with restrictor, and more than 1.4 without restrictorFast Guy said:
it was a Gr.N rally car but at the beginning he want to go Gr.A, but it seems to be more easy to win in GR.N.
Why did you say it ? do you have special information in this case ?

Some of us do
I think the whole point with EGT is that it will differ from car to car.
The best way to use it is to get the car setup professionally so you KNOW that it isn't running weak or detonating. Make a note of your EGT levels.
If the car starts detonating, your EGT will fall dramatically. If ur running lean and the det doesn't kick in the EGT will rise dramatically.
So get it setup - learn what temps it runs.... then if any major changes occur... go and see your bank manager and then your mechanic .... in that order.
The most important thing here is that your EGT will actually fall if you start to detonate. So you'll be trolling along at 950 deg C thinking all is well......... NOT
It's worth running an AFR gauge alongside. But bear in mind the output of the lamda sensor on the R doesn't provide the correct voltage range for off the shelf AFR gauges.
