Another 9.24 this weekend

First pass was was in the 9.3x range @ 144.x mph with a 1.5x 60'. First pass on a brand new set of radials.


next pass was an equal to my previous best, exactly the same ET 9.247.. Here is the break down:

--- -----7/11 -- 8/15
60 -----1.414 - 1.424
330 ----3.811 - 3.843
1/8 ----5.870 - 5.905
MPH ---118.41-118.71
1000 ---7.681 - 7.705
1/4 ----9.247-- 9.247
MPH ---142.49- 145.23

Only difference was the new set of radials. I need to ramp the N20 in a bit faster.

The next pass I ramped the N20 in a bit faster but I think it spun just a pinch 1.43 and it slowed down as it was my 3rd 300hit pass with a 15lb bottle.. 5.956@116.96 and 9.387@140.0

Last pass I had real bad wheel hop during the burn out. Left with a 1.436 60', and about the 1/8 the vibration was bad through the 1/4. Threw a wheel weight. went 9.325 @ 142.84.

It needs a converter change for sure. I hope that gains me a few % of efficiency so I don't need to go to a 3.73. Going to try and get the front end on before next outing.

I know there is some form of high 9.0x to low 9.1x in this tune up. Just need to find it.
