Good idea or not???
I was thinking and I've been doing this for a couple weeks now. As soon as the truck starts I step on the throttle till about 1500 rpms then let off. Oil pressure goes up so much faster then starting it and letting it idle. Oil would be getting to the bearings a lot faster, right? Which in turn would be better for the engine. Or I'm I all wrong?

Oil may be getting to the bearings faster but you are also turning a lot more "dry" revolutions than if you would let it idle up to pressure. In my opinion, the faster rotation of the crank etc. would have a greater chance of galling a bearing. I never rev an engine right after starting unless I have been cranking it for a while trying to start it in cold weather or some other reason. I'm sure others will chime in on this one. Good topic of discussion.

Eugene could probably give you some good specifics, but IMO I am with Mark on this...

I see what your saying.
Example, some of the john deere tractors rev up a little on their own when you start them. I have a JD 4440 you can have the throttle pulled all the way back, and it will still rev to 1,500 or so then return to idle. I was always told that was to get oil pressure up faster, to help the engine last longer. So I figured if thats the case, why wouldn't it work on our trucks? Maybe I was given false info I don't know, but I'd like to find out

I'll ask my son-in-law about John Deere's idea. He's done quite a bit with Deere engines.
My NH 8970 does the same as your 4440. Certainly wasn't comfortable with it when we first got it but guess that's the way it is.
Clay, I too was thinking that this would be one for Eugene.

Maybe not, they all have their own personality. This is about how ours starts, worse in cold weather as it'll romp a little more. 'Cept no way in hell would we straight pipe any of our tractors, who wants to listen to that all day?

I was surprised to find out how many farmers video their tractors and put it on the internet. Weird.
