List,

Here is part #2 of my 2005 saga.


Monday morning, after flushing some of the lakes dust off the car, I 
began disassembling to the point where I could view the plumbing of the 
fuel system. As I had suspected, I had installed the jet box, which 
contains a check valve, backward. This explained two things...at 
Bonneville, we were running alcohol with gasoline nozzles in the 
injectors. With the jet box backward, there was no pressure relief, the 
computer said the pressure was over 200 psi, but I didn't believe it. I 
thought there was a problem with the sensor. This forced enough fuel 
into the system to make a decent pass...225 MPH. With the proper 
nozzles, there was too much fuel for the engine to run properly, above 
less than = throttle. The reason it ran up to that point was that the 
secondary bypass is operational allowing a reduction in fuel flow to the 
nozzles.

Was this year a success? Yes, making mistakes is a form of education. If 
we were at our best consistently, we could get puffed up and think that 
we really had control. Events such as these help to keep a person 
humble. Hopefully, in the during the next six months, we will get it right.
