What to look for in a prebuy?

[mshac]

Firstly, congrats on owning a P337!

I hope you got some consideration from the seller because it won't hold pressurization. I hope its just a dump valve, but I doubt it. Keep us informed.

The rpm situation on the front motor indicates one of three things:
1. Weak turbo
2. Weak/misadjusted wastegate
3. Intake leak

I'm sure there are other possibilities, but chances are good you'll find your issue in one of the above.

Enjoy your new airplane and don't forget: PICTURES OR IT NEVER HAPPENED!!!

Here she is after my flight home.

Nice!

Looks like it has intercoolers. You're gonna want to check all that intake piping for leaks on the front engine.

I attached the flight records from last night. Your speed claims are backed up by the data. Looks like you didn't get out of there until pretty late. I guess you got to test out all the lighting!

Yeah, It has Riley Intercoolers... Thanks for the heads up!

I do appreciate all the input from everyone... it has been nerve racking before and after the sale.
