Daytona was awesome!

 

I knew before we got there that we would hit the aero wall, I just didn't know at what rpm.  When our first driver went out and reported that he was turning 4k rpm's on the pace lap, I got a little worried.  As it turned out, we didn't run out of steam until 6k in 5th gear, and while not as fast as most of the bmw's, it would put shame to the miatas out there.

 

We were doing driver changes every hour and fifteen, and using around 7 gallons of the 110oct fuel.  That was a lot more than the old set-up, and after about 6 hours of running smooth, (which has also never happened) we realized we were going to run out of fuel 2 hours short of the 14 hours.  No one was running anything but 93, so I sent one of the guys out for gas.  I was going to start cutting our remaining 35 gallons of 110oct  4:1 with the 93oct.

 

Until I saw the car come in tucking the driver front tire.  Turns out we snapped the friggin' torsion bar!

 

 

 

After about an hour and a half of ways to salvage the suspension, I resorted to locking it down.

 

Anyone know the spring rate of a 27mm impact socket?

 

It drove ok, the banking being the easy part, but it had no traction through third gear on the flats.  It just spun the crap out of the passenger tire because of the torson diff, and didn't want to turn right on the road course.

 

We finished 56th out of 123.

 

 

 

The itb's worked great.  At full load our afr's were hanging out right at high 13's and low 14's, which I feel is acceptable for the fuel we were using.  I only got hints of reversion through the "Bus Stop", where I was part throttle, but still under de-cel.  The ghetto afc also performed pretty solid. All in all, I was very happy with how it all worked.  

 

Good times,

Matt
