World Time Attack Challenge 2011: Day 2- Friday Competition

,

Cyber Evo was behind their 2010 championship time, but before anyone could start speculating on who would dethrone last year’s champ Tarzan put down a 1:30.3690.

 

Sierra Sierra did not go out in the morning or mid day sessions, but ran a 1:30.7490 in the afternoon session.  Good enough for 3rd place.  Something tells me they have a little something saved up for tomorrow.

 

Now lets go over the rules for each of the individual classes, starting with the Pro Class.  This is where the big boys come out to play!  Teams competing in the Pro Class must be invited by the WTAC selection panel.

The 1:30.6160 of Garage Revolution’s RX-7 gave them the first place spot for most of the day.

 

I’m guilty of poking fun at this car as much as the next guy, but I’m also man enough to admit when I’m wrong. The MCA Suspension S13 ran strong and is currently in 7th place with a 1:33.9720.  And yes, we will be doing a full MotoIQ Inside Look of this car and bringing you some very interesting details on why and how this car’s aero package was developed.
