Performance Tuning Plan

As an aside - A friend of mine works for a company that designs and builds DPFs for OEM applications. The max temp specs the engine manufacturers give him (that the DPF has to handle - so basically post turbo EGT) are very high. I suspect that modern diesels may have some high performance alloys that allow them to run higher EGTs???

Sorry I was not thinking of modern vehicles with cats and DPF where post turbo EGT is important.

It is the combination of high pressure and temp that causes the issues with materials. Some modern heavy vehicle engines e.g. Cummins now use steel crowned pistons.
