I am trying to find the highest EGTs that you guys are seeing on a properly tuned TT or ST VQ35. Does anybody have any input?

 

Under full boost or long highway pulls, mine typically gets up to 700-800 then I back off. But mine is not tuned either, I'm still running on stock ecu.

 

I have seen a little of 1000 F but it all depends where your probe is mounted.

 

i'm getting 800 at idle. the sensor is mounted next to cylinder #6 (the hottest one)...when pulling hard i'll see that go up to 1200-1300

 

Mine is probed same place as cajunstyle. On real hard pulls it will go into the 1400's . Normal pulls I see between 12 and 1300. My engine builder told me once you get to 1600 for any kind of time is when you will start melting pistons and do some damage.

 

Just cruising on the beltway i see 1300 to 1400.Pulling hard i see 1550.

 

1000-1200F cruising & 1300-1400F at WOT. Was told by www.danzioperformance.com to avoid going beyond 1400.

 

I see 800-1000 cruising and 1200-1400 WOT. As stated above it depends on where your sensor is mounted.

 

Sorry if I find this humorous, but no one is adding a C or F... EGT gauges come in both, so it would be helpful in this conversation if anyone knew for sure what temperature you are talking about

 

I see 800 - 1000 F around town, at high speeds and under hard loading conditions I see 1200 F. Haven't seen any higher. My tuner also said that 1600F is the limit.

 

My sensor is about 2" from the head. I regularly see up to 850C (1560F) at WOT. Up to 875C (1600F) is still okay. More than 950C (1750F) is when you start to have to worry... I've seen up to 1800F on my car when untuned and did not have any damage...

Stock block and internals. Please specify if you have lower compression pistons as the EGT will dramatically be affected in this case.

 

Mine is located 1 inch for the exhuast housing of the turbo, on the downpipe. I see about 1150F cruising, and about 1250-1300F at WOT....pretty steady at WOT.

 

Sharif, as far as I know, there will be a huge difference if it's before or after the turbos. Mine's located before, about 2" from the head. That alone could account for 100-300F degree difference. also, you have a built engine with lower compression pistons, which makes a big difference.

Thanks!

 

Cyliner 6 is the hottest cylinder correct ?

 

Well, the reason it's the hottest in mine is because that's where one of the turbos are mounted. Since the turbo produces heat it's going to heat up the cylinder next to it--it's a good idea to keep an eye on the hottest one

 

Let be realistic, if those temps were C people would be having HUGE problems. If you think for a second then you would know they were F. I thought the question was funny though.

 

Sorry to hijack this thread a little,

I have the defi oil temp gauge and it's about 140F while cruising on hwy and about 190~200 when stuck in traffic. I'm in CA and weather is around 60~70...Is this normal or should I start looking for oil cooler...hot summer is comming and I want to get prepared. Any feedback would be greatly appreciated

 

anyone know the general EGT difference between turbos and superchargers? What about with headers?


My installer put my EGT sensor at the collector of my crawford headers - he said that would give a more accurate overall reading between all the cylinders. Is that BS? I read that it shouldn't be any further than 6 inches from the block - where it is is probably like 12-15 inches from the block as far as the length of piping of the headers

 

My EGT Sensor Mounted 2~3" from Cylinder Head #6 Cylinder

I had a None Tuned APS TT at Full Boost (10.9 PSI) my EGT is 810C with 100 Racing GAS

It's O.K ????

 

yes, 810C is just fine.
