When I had my civic and my z31 I would do 1 or 2 WOT through first and second every time I drove lol. Mostly because there wasn't a lot of work done to them so they weren't going to blow up on me. Now that I have the TT I rarely floor it, usually only if I have a passenger that wants to see how fast it is, and I never go more than 5 over and never floor it in any kind of traffic. Also its my only car at the moment and at the power im running now its pretty much well past any kind of reliability seeing that I'm still running stock internals.
Once I get my daily driver built Ill be hitting the track and flooring it a lot more often.
