The Daytona: June 26, 2008

by on Jun.26, 2008, under Daytona

Another awesome time at SDAC has come and gone.  The performance driving school was a blast as always.  The Daytona did great overall, but the stress did highlight some issues.  The intercooler definitely needs to be kicked-out at the bottom to allow some air to get around it.  The loss in cooling capacity was very obvious after a few laps, though it will happen on the street in traffic with the A/C on as well.  I’m thinking of buying a new fan as well.  The other issue was oil pressure.  I know the pump has issues and when the oil temps got high, I was seeing only about 30psi of pressure at 5000rpm.  Not good, so I think it’s time for a new pump.

I made 14 passes at the drag strip.  Times weren’t what I had hoped (was shooting for 13s), but I didn’t break the car.  I couldn’t get the car to hook nor could I get it to make more than 18-19psi of boost…even with the wastegate unplugged.  I also trashed 3rd gear by the end and it seems that it will need a new syncro.  Did a bit of tuning, but most of the effort was spent trying to learn how to launch the car.  Best time was 14.269sec @ 98.87mph.
