Does any one see any issues with a m-TDI pump running and engine at 6000-7000rpm?

I know then engine can do it, i am just wondering if the pump can handle it.

mean piston speed will get critical at about 6000RPM.. i think the
returnsprings in the pump will handle that too, but the it is meaningless
to go beyond 5500RPM due to bad flow capabilities in the intake..

I am not worried about flow...that can be adjusted with some porting.
I just want to know if the rest can handle it...+6k rpm. May have to look at reduced piston weight...

I don't really know why everyone wants to rev the hell out of these engines. You rarely even see horsepower peak past about 4200 RPM so it stands to reason that you should be more concerned with making power up to 5-5500 before you should be looking to 6000+.

It's not a gaz engine, it's only my opinion but It's the same thing if a guy install a K03 on a VR6 motor to try making big torque power in the 2000-4000rpm range..... that of pretty lost HP.....
