Yea I would definitly say your drain is a ton more efficient than mine is. I have a 90* upangle while your's flows pretty much straight in. And no I don't run a restrictor, I have been thinking about adding one but I really don't want to "cook" the turbo either.

 

What size is your feed line Neal?

Man, I am really nervous about using a restrictor, but maybe it would be worth a shot before pulling the turbo out. I assume most of you guys use a nitrous jet? Anybody know the biggest jet you can get?
