I bought mine last night. Kind of excited to see how it does vs my x37. Probably gonna run 91 and call it a day. I'm not out there racing everyone. I just want a great daily.
We got [MENTION=1650]Pete[/MENTION] 's x47 in today. When his engine is done here we will be shipping it back and ready to tune! Thank you Tony for getting it shipped out!

Super excited and thinking of going X47. Had a few questions for forum and ISH. Upon ordering seems like have option for 11or 17 psi spring. Why does it seem 17 is the go to spring. Can the 11 still hold the boost up top?? ISH can you share the calculated airflow (lbm/min) of your new setup. thanks

I believe the pumaspeed test car ran a 11-13psi wastegate. Other than that i can only speak for myself. Im using the 17psi turbosmart wastegate preloaded at 0mm to very little preload. That indicates to me this turbo flows very good. Compared that my x37 i had that thing preloaded at 3mm and im sure other hybrids are preloaded in that area to hold boost up top. If you take a look at my vdyno you can see the boost curve doesnt even have a curve lol its just a straight flat line from 3200rpm-7k.

Thanks. I think that I'm going to give the 11psi spring a shot first. Will allow a little more range if I decide to do boost by gear or something like that.
