a little test and tune at orlando speeworld

[aafc]

March 6, 2013 Orlando Speed World was open for test and tune runs.
temp was about 68 deg. with little wind and low D.A.
Car : my 1990 ZR-1 with 4l80E auto and 3.73 rear gears.
1st pass left @ 1200 rpm 2nd and 3rd passes left @ 1800 rpm. each pass
trans shifted @ 7000.

my 1st pass @ 6:50 p.m. 2nd pass @ 7.31 last pass @ 8:48
R/T .371 R/T .776 R/T .581
60' 1.719 60' 1.698 60' 1.722
330' 4.917 330' 4.865 330' 4.888
1/8 7.525 1/8 7.452 1/8 7.473
MPH 92.26 MPH 95.03 MPH 95.10
1000' 9.787 1000' 9.698 1000' 9.716
1/4 11.687 1/4 11.585 1/4 11.600
MPH 118.49 MPH 118.80 MPH 119.38

As you see i need to work on my reaction times, but the runs were great
plus track traction was very good. as my 60 ft times last year were
1.74 to 1.78.

After racing as i put the " Z " back in the garage the mileage just turned
over to 121,000 miles. When the weather gets warmer here i think my e.t.'s
will drop to 11.75 or slower.

Thanks for reading
