Turbo Club Before Turbo Modifications P12, Power up Serviceability Technical Information on Modifications for JDM Imports

CONCLUSIONS

Conclusions on power up serviceability .
The implications of progressive or high boost mods to the engine are always present in the way of stress related engine failure or detonation because of lean air fuel ratios or heat or timing problems . High power mods always lead to increased chance of problems but if working from a position of knowledge, the chances are reduced.
I believe the best way to avoid detonation is to dyno tune your car on a gas analyser after mods to ensure the fuel air mixture at max boost is still not leaning out. If you use the same dyno each time you should have a valid comparison on power increases after each stage.
As figures across different dyno's tend to conflict, don't take much notice of the numbers except as a guide. The most important aspect is the fuel delivery at maximum injector duty cycle and boost pressure as measured by the exhaust gas analyzer.
Always ensure that the dyno operator has a large fan directed at your intercooler if fitted as well for more accurate results.

Detonation is to be avoided at any cost.
