Okay I'll come right out and say it on the List.... Yeah I am going to go
to the WOS and the weekend Prior I am going to try and run El Mirage....
then I am coming home and running the September Maxton Meet....
Needless to say Middle of September on is going to be UGLY... but I am
going to have fun.... and try and get a record at El Mirage and Bville...
I am finishing the Rodeck and putting it in the car.... then off to the
Dyno.. rebuilding the D motor I ran at Speedweek to take as a Back up...
Dave has given me a shopping list of Junk I need to be a Real Racer.... you
know like Compression gages that aren't Broke ( tried it and it didn't
work! ) and a Leak down Tester.... Sring tester...oh and he wants me to
have a REAL fuel system that doesn't get Heat Soaked by the Radiator....
Bypassing Regulators to keep the Fuel Flowing.... Geez these Engine
Management guys are tough.... Shoot I was just out having FUN... then I
decided to go fast TOO.... oh well... the price of fun....
No one has ever gotten a car into all four Two Clubs in one Year... that is
the stated Goal...
Keith ( Why Yes I am Brain Dead....)( Hey Joe... How's that Hat Fit?)
