The pull at Braymer MO.

Truck pullers, how's the truck working ?

I think he needed to be a little meaner to the clutch at the starting line to keep the rpm up more. The sled was set up tight. No one in our class went 300' we went 291 and change.

Got that truck crankin' for sure. Sounds good to me. Don't know much about pulling, but the truck looks planted the whole run no hopping and jumping. I see what your saying, did seem like he rode the clutch out, maybe some more initial wheel speed would get it up and moving quicker.

Do many people run automatic trans? Just wondering how a well built glide or TH400 would work in an application like that.

Not very many people run autos around here

We’ve talked about ifs before how’d it work
I know there’s a big truck that’s trying it out it will be the true test see how it handles 1200hp

The Milan pull.

Change of tire pressure, q16 maybe, wouldn't have needed much to pull 2 inches farther.

2 way tie for first place in prostreet points now.

Yes it's hard on parts. :)
Diff gear is 4.10
sm 465 trans.
Dual clutch discs

He didn't let off the clutch till 200' on that run.

The clutch comes in on it's own. Just hold it to the floor and rpm will engage it. Set up to come in about 8000 rpm right now.
