Just wondering what other people are seeing for EGT Temps on their Greddy Twin setups with the probes in the manifold (Not after the Turbo's)

Just want to compare what I am seeing.

Extra points if you have ceramic coated manifolds and turbo housings.

Thanks for your help.

Please post what boost pressure you are running as well (and current HP level if you happen to know) just to try and keep things straight for comparisons sake.

 

Mine's an APS TT, but that should not matter, it should be about the same.

I am running 9.5psi on the stock block and dynoed 450whp over 3 years ago (still running strong!). I have ceramic coated manifolds and turbo housings as well. The EGT probe is located about one inch away from the head exhaust port on the driver's side. I am running 94 octane pump fuel and 50-50 water-methanol injection.

Average EGTs are around 875C at WOT, but I regularly see up to about 925C when I hit max boost. I would not go above that...

There, from one canadian to another... :-D

NOTE TO EVERYONE WHO MIGHT POST AFTER ME: specify Celcius or Farenheit.

Later,

 

Canadian here too.

Greddy TT, Coated Manifolds, Coated Housings, EGT probe is located about one inch away from the head exhaust port on the driver's side too.

94 Octane, no meth.

8.5 PSI Stock Block, the highest I've seen so far is about 840C.

 

Great to hear your replies guys.

I feel super good now.

At lapping day I was seeing 1450-1500 F MAX. Running 94 Octane Pump gas, 7 PSI, (395 HP at the wheels with this setup)

I also run VERY conservative timing with the Haltech.

Thanks for the Info.

 

Last night I saw 1612F for the first time while tuning...

 

900C is a general rule of the safe limit, but a little hotter is nothing to worry about. I just mentally double checking something things at that point.

 

1652 is hot, i think. I have hot lapped my Z and never seen temps over 1400, however that may change. Let the tuning begin, lol

 

Thanks for the ring in Shariff,

I would certainly have pooped my pants a little if my EGT had maxxed out my 1600 degree F EGT Guage. :-)

 

Anyone have pics of where they actually tapped the manifold? I'm installing an APS TT just trying to get some ideas; I was trying to find the 'hottest' cylinder, but with these cars I think it also comes down to what you can reach and where you can fit it.

If anyone has any input on where to put the sensor in an APS TT kit w/ the external gates, it would be greatly appreciated.

 

Have a look here, you will find some pictures of the APS manifold with the EGT sensor already plugged in:

Vortech @ 9 psi, 930 C.
EGT probe is just before the cats ( passenger side)
