EGT Limitation

[mrx79]

Hi,

Due to a very small tubrine, my engine is EGT limited. With increased boost and increasing rpm's (redline is about 8000rpm) egt is the limiting factor, even with reasonable ignition advance, so advancing any further is barely an option to reduce egt's any more.

Because the engine is about 8:1cr it's thermal efficiency is also not very high compared to higher cr engines.

So i can use water injection to increase my det. threshold to be able to run more boost, but, 100Water and 50/50WM doesn't lower my egt's (some ppl say it should, but i never noticed it during my logs).

So do you guy's have any ideas what i can do to keep my EGTs low to be able to run the boost with water/WM i'am able to do det. wise?

Thanks in advance
