| No changes to ConVerTT (black convertible) this year and she is still running strong - basically 350 hp / 350 tq on stock turbos and stock injectors. XtraVerTT (white convertible) got the full breather mods treatment and a set of sport500s. Last year it had the gt28rs turbos and stock intake and intercooler pipes. Here are this years results on 94 octane: < > This chart show the year over year overlay. Red is this year (sp500 and 2.5 breather mods, ash massives, and SZ 3-2.5" TPs with hi flow cats), blue is last year (gt28rs, stock pipes, z1 ICs and SZ 3"-2.5" TPs).

And finally, just for fun, here is SlickTTop (gt28rs this year) overlayed on XtraVerTT (gt28rs last year) on 94 octane:
