Vortech supercharger track experiences

[geeitup]

Greetings,

I recently had my Vortech V3 leak and fail while tracking my car. So I need a SC rebuild. My setup is a Topgunz/Stillen kit detuned to make upper 400's whp.
I really only have done maybe 5 track days and have only done about 7/10th driving as I've been setting the car up from street performer to track reliable (haha).

I'm getting mixed information from Vortech indicating I should be using an externally lubricated version, or even a V1 with a heavy duty bearing and straight-cut gear (loud!).
It doesn't seem logical that external lubrication would help, since in my case I would have been ingesting relatively unlimited engine oil into my intercooler/intake. Also not sure on the oil temp argument for internal vs external oiling, since track oil temps are pretty hot (200-220).

What has your track experience been supercharged??

Thanks!
