This is directly from Tim Berg of Black Magic...
With our clutch kit only, the same sled ran 108.5 mph in 1000 feet and had an ET of 10.45-10.5 consistently with the slowest run being 10.53. The top speed went to 115.7 in the 1/2 mile run.
If you are going to set up for a 500 or 600 foot run----you will want to use our kit with a red/white driven spring and attempt to pull it at 7600 RPM or so for the shorter run. Our kit is designed to accelerate at 7800 RPM with full shift out @ 8000 or slightly above to 8100 on a longer run.
