Dragy is sweet.

[TD Max]

New modern incarnation of the old Gtech/Gtech pro. I actually used my old Gtech (accelerometer version not GPS) on my Sportsman ATV when doing PC-V tune testing and clutching work and it was quite consistent and repeatable on my 0-60 runs. I prefer to make a minimum 3 runs and if they are consistent I keep and average. If not I run again until I see a pattern, but seldom had to run more than 4 runs. This was asphalt for consistent traction. Looks like Gtech is still around as well and much more modern now using GPS like others.

They have a refurbished one on eBay for $119.00 may have to get one for my summer toys or my toy at work when I get back.

Anyone know how the dragy works in the cold?

I usually wait for a warm day with cold temps coming. Then I groom very wide on my 660' track so I can do three passes with each change I make to the sled and then average. That way I can do many pulls on very consistent vergin hard pack. If I don't have those conditions on snow I don't test. Otherwise you can end up chasing your tail. I think the dragy will be easier to use and better to store data on.

Out this morning on decent snow pack, but not perfect. 260 map with stock muffler. Thoughts? Good or bad.

@KnappAttack
Mike you have one of these right?

Others also.

I recently bought one. I have the TD unit also. The Draggy is a lot more convenient! I tried it the other day on my 2020 f250 with the 7.3 10spd. 2.44 60' 15.60 1/4mi at low 91 mph. Lol Had covid followed by a stroke so haven't been on the sled yet.

The G chart(brown line) shows my lack of traction at the start.

Lol my truck picked up .2in 4x4. My 18 ltx is stock except muffler, manual boost controller and fuel box. With the TD timer on hard snow i ran 1.57 60' and if I remember correctly 6.7 6.8 660' at 101. Anxious to get the Tapp dialed in and on similar conditions with the dragy. A little more setup and the Tapp maybe low 1.5's on hard snow?

Where did you mount the dragy? I have one but haven't been out yet. Waiting for mother nature to give us some more snow.

Yes, more bite needed.

Obviously not ideal, I was in a hurry.
