This thread may contain highly technical aspects in relation to some very basic ones throughout. The complexity level of these analysis procedures (regardless of maker) can get very deep and expensive from testing & observation tools for those new to the realm. As for surveys, they do help in the process, its just the quantity of people responding with completely filling out the survey that can make it very useful or not very useful. Albeit, no matter what, IMO a survey can be used as a directional tool in terms of a starting point in a engine failure, transmission failure whatever it may be.

This thread will be professional, no ranting, no targeting a particular brand, no bad mouthing another forum member period. No emotion shall be present besides having an interest in narrowing down collateral damage to the root cause and eventually producing something positive.

Failure analysis & diagnosis is a tricky world. Regardless of the fuel used to produce torque. The one thing that I have come across while going through the process is; a failure does not happen until SOMETHING makes it happen. For instance bearings, bearings would not fail if everything was clean and friction was almost non existant. Everyone on the forum is I am sure, very thankful to have numerous industry professionals on board here to help in times when a problem is occurring along with other very knowledgeable people.

Here is something Russ brought up for an addition in Failure analysis, very good read and should be read by everyone interested.

Problems currently are piston, connecting rod, crankshaft damage & failure resulting in demolition of the block and oil pan. While being on mostly the 80hp level from a DP-Tuner and possibly a couple other tuner companies in the mix as well. Although other damage has been present at other horsepower tune levels too. DP-Tuner being the most popular can not be struck as being the culprit as whole as there are other companies that are in the buiness. You also have to take into account that people do abuse the machine we call the Internal Combustion Engine.

For reference only (the directional tool) here is a survey that has been presented recently which will eventually become obsolete once another survey has surpassed this one.

When you improve an engine's performance, even one thing, you must adhere to it as a whole new confirguration. Very vague list of areas we need to persue are combustion, timing, fuel characteristics and component characteristics.

I leave today with these questions on food for thought for everyone.
~What can cause the cracking of pistons?
~What can cause the breaking of connecting rods?
~How does the different timing setting/tune affect the engine performance and damage occurrances?
