Turbo ancronyms and words

[thermal]

Turbo models: Would really be helpful if everyone can fill in what turbo can handle how much boost, what rpm it starts to spool, when it gets to full boost, what size engine the turbo is optimal for, what make/model car a turbo is stock on. ie: T3/T4/CT26/TD04/etc.

This question is summarized on this thread:

To add to that thread, turbos have different trim sizes. A great example is the T3. Some of those turbo size come in a .48, .40, .60 etc.... Trim sizes refer to the sizes of its efficiency. Like if you hear the AR 60/48. That means that the compressor side trim is .60, and the turbine side trim is .48.

Spool time depends on the relative flow of the exhaust gas and the trim size of the turbine. RPM, engine displacement, and thermo dynamics are also involve somewhere in the equation. Boosted3g probably has the formula somewhere. On the other hand, spool time directly affects how long will the pre-set boost will be achieved.

Maximum boost and boost setting are 2 different things. Maximum boost is the highest pressure that the turbo (compressor) can achieve without being regulated by the wastegate. In other words, the highes boost the turbo is capable of. Boost setting is what the maximum pressure that the wastegate is allowing to boost.

However, I can tell you now that the TDO4h-15g like mine hits boost setting at around 4000-4500 RPM. It starts boosting around 2500 RPM.
