Default Re: Notes on the XD cam from Professor Ko

Hi all, one thing i am amazed at is that people swap parts from one engine to another with big HP increase expectations. I am not an engine engineer, but i do know this as a fact: Engines are designed as one. All designs take into consideration another. That is why when mods are done to a stock engine, one must take into consideration the changes it will cause elsewhere in the engine.

For example: When turbo's are installed, people think that adding the turbo and supplying more fuel does the job! Well think again! Cam timing, cam stroke, compression ratio, cooling capacity, exhaust capacity, air/fuel ratio, mass air sensor vs turbo CFM, fuel pressure, fuel pump capacity, injector duration, timing, conecting rods etc...etc...etc....

You better plan your actions before making even the slightest change. I think that a good engine modifier will take into consideration all of these variables and modify the engine in a way that will prevent engine failure and save a lot of $$$$ in the end while yielding a lot of additional horsepower!!!

Thanks for reading....

Regards to all

Sean
