As you can see the hauck setup was faster et and mph than my best Drag N Fly setup Also the the Drag N fly was better pulling lower rpms both in et and mph. Now this was a 1000ft not lake race. In a 1/4 mile or less my testing shows lower rpms is better. The same was with the hauck setup.

11.27 11.48 11.38 Avg 11.37 to 10600 mph 112-113
Pulled weight out of the tip to get rpms up to 10800 and it was a little slower in et and turned 112 on top so as you can see pulling it a lower rpm is better in a 1/4 mile or less. I cannot say this would be true in a lake race.

As you can see very much the same in et but still lower mph. This was with the drag n fly engaging at about 3700.

Final test drag n fly with black primary spring vrs best hauck setup

As you can see the drag n fly setup was better. The drag n fly with the white primary spring was the slowest. The drag n fly with a lower engagement spring was about the same but had lower mph. The drag n fly with the black primary spring was the fastest and also had a couple mph increase. This was the best setup to date probaly will try the new super rat weghts next year vrs this drag n fly setup. My conclusion is with hauck or drag n fly in a 1/4 mile drag or less distance keeping the rpms 10700 or less is better et and mph. This doesnt mean it will be better mph vrs higher top rpms on a full lake race. These were my results with my 07 attak with ram air lid and 23/40 gearing running 162 studs with cobra track. Also the mph were on speedo not gps. Thanks just wanted to share my info I have been testing the drag n fly for the past four years with many different combinations. Thanks again Kurt

Are those speeds gps or speed trap speeds,if so that is impressive in 1000 feet,was it still 1000 ft. for 110-111 mph or was that just flat out top speed,was it ice/hard snow and yes,the blk. spring always run cooler on my apex,w/23 top and at 10,800-11,000 best speeds and hole shots,mine was set up with 5.2 5.2 4.8 and 5.2 OD this i posted two years ago,and alot told me it did not work,but for me,it was awsome. Very good write up. pete

The engagement with the black spring was about 3800 rpms but was pretty smooth. It did shoot out of the hole unbelievable. Best holeshot setup to date. The 110-111 mph was on the speedometer. The track was a trail which was a good hardpack temp was 23 degrees and not exactly sure on distance seen this was not my regular testing site it was an actual snowmobile trail on my dads land. I measured with my truck, from my starting point to the end and was about the 150 ft less than 2/10 of a mile. This would put it about 900-925 ft. Thanks Kurt
