Anyone with in-depth turbo knowledge able to post acceptable EGT figures for a T25 to handle?
I have a BMW M30 3.5 six cylinder with twin T-25's in my Alpina B10. Runs 12 psi max. 367BHP 388ft/lbs.
On another forum (not naming names) a guy posted saying these engines are very fragile as the EGT reaches 1200 degrees C at 286 kmh etc. and cracked heads are common...
I'm no expert on turbo temp limits but would be very surprised if 1200 degrees was attainable let alone sustainable in a production engine that, in my car at least has covered 100,000 miles without missing a beat on original turbos.
Just curious so if anyone knows, please chip in.

From memory anything above 1200 deg c is is not going to last. Less is better obviously.
If you can get less than 1000 deg C I think that is good. Intercooling helps massively especially water injection.
I'll ask on the Mazda GTR forums they have similar issuse when getting above 320bhp from the little 1.8 with the truck turbo's on.
