Successfull Tracking with Forced Induction??

I bet you most of the people who own Zs and want to TT or SC them have never ever reached the limits of their cars on a track. Its like some stupid wet dream you have... oohhh I wanna TT it so i can go FAST! Let me tell you this -driving on a track is wayy more fun when you and the car and communicating. What I have found is normally - FI'd cars tend to have a non linear TQ delivery causing some very funny moments mid corner. It will take you 10 times more seat time to get warm and comfy with a TT'd 370 on a track as compared to an NA one. When I was at infineon, the Z could not have been more predictable through the corners - something I am not willing to compromise for a second in the quarter and more passing power on the freeway. My 2c tho

TT are definitely heaters but what about SC? I'm assuming the heat generation issue would be a little less and perhaps a bit more manageable. The low end torque would take some getting used to but exits to the track out would be kind of fun.

I find myself standing on the gas going into the "short" straight at Pacific Raceways and would love to bump the speed up sooner rather than wait some distance for it. Of course how I set up on the corner (prior to) has a lot to do with how long it takes to wind things up.

This discussion is also relative to where one tracks their car. Some courses are better suited for big power, whereas others are pure and simple corner management. My 2 cents

I agree with the exception of SC applications. Look at the TQ curve of every supercharged z34 thus far. It essentially looks like a stock curve only higher on the graph. FI isn't the problem TT is. That being said HP=Heat. The only way to sustain the kinds of power we are talking is with massive oil cooler(s) and a larger oil reservoir. Doesn't mean it can't be done, but you're probably looking at something like an 8-10 qt oil change.
