tang0,
This is the forced induction performance section of the forums, I hardly think a roof rack fits into this category. Please delete it and repost in the general section.
Stock driveline and street tyres. Anything else you'd like to know about?
Nah, it's too wet over here so they don't have any proper drags till much later in the year:(
I don't think such a high boost level is sustainable long term.
I have some good tyres for my car, but my twin plate is slipping, and the drag season is finished. So I have plenty of time to prepare for next season.
