Default Turbo Heat Ranges?

Was at the track this past weekend. After a session i did some checking of temps in the engine bay. I'm getting some really high numbers for the turbine.

Turbo turbine housing - 2000 degrees F

Is this normal?
I was thinking this is a bit unsafe. Say if the oil return hose were to burst or something and hit the turbo, instant fire!

Forgot to mention turbo setup.

It is the turbo from the Greddy kit, but I only have the turbo. Apexi Intercooler /w custom end tanks, ARC BOV, custom intercooler piping. Running a fairly big Setrab oil cooler too. I think the oil temps were a bit low, due to the extremely cold weather, around 160 F. Running 10w30 Mobile One oil.

Water Temps were around 180 F, but for those who dont know, the TD04 is only oil cool.

Hopefully one of the experts can comment but I believe normal peak power exhaust temperatures are about 1650 degrees F. So, yes, that does sound high.

but what would cause that. i can't think a single thing that i'm missing. my IC is fairly big too, proper oil cooling.

Forgot to mention, boosting roughly 12psi.

EGT roughly 1600-1700 F
AFR is pretty rich too, but completely safe. Probably 9.5 AFR at 12 psi

1. I'd love to hear what you're using to measure temperatures in the 2000 degree range. The best automotive pyrometers out there max out at that, and I doubt you held a pyrometer on top of your compressor housing long enough to get that reading.

2. 9.5:1 AFRs are not safe. You're washing your cylinder walls down with fuel, which corrupts the oil and causes spun main bearings. Learn to tune your car, or hire someone who knows how.

edit: What the **** do you mean by "probably" 9.5:1? Do you have a wideband or are you guessing?

1. im reffering to the outside compressor housing temperature. i'm using one of those Infared temperature guns.

2. Funny part is, this was after tuned. the tuner fucked up. I'm going to another tuner next month. didnt have time to get it tuned again before the event. I was assuming that as long as it's not too lean it was okay for the mean time.

i have a wideband, LC-1. wasn't data logging though.

You do mean your turbine housing not your compressor housing right? Not trying to split hairs just making sure I understand.

Not sure how your compressor temp would be higher than your EGT. I'm going to agree w/ Savington and say its your instrumentation.

woops yeah ment to say turbine, sorry.

i was using something like this to measure it
Craftsman Non-Contact Infrared Thermometer, High-Temperature, Laser-Directed - Model 42540 at Sears.com

i know its not 100% accurate, but even in the ballpark that's kinda high.

Seems a tad off, although you are still about 800 degrees or so away from melting it.

Listen Simon; get past Savington's poor choice of words and fix those AFRs asap!

What EMS are you using?

Do some street tuning as soon as you can. Take those AFRs to between 11.5 and 12.0.

His explanation is solid.

BTW, please post your location below your Avatar. This way we know if you have some other forum member close by.

You don't have any hesitation or bogging with that AFR?
