Most high HP pullers are running lower boost numbers than drag racers. They also overfuel and run water to fight heat.

Motors
You can not even compare what a motor takes drag racing vs pulling! You will never load a motor pulling like you will drag racing. Pullers hurt'em also just not as often. Pulling your motor is up and never comes down. Well it shouldn't come down at the end
. Drag racing the motor goes up then down many times with a big load in the big gears! That's why so many drag guys want to run the 1/8. They hardly ever break at that point of the run. Same goes for trannies! Pulling is a hole lot easier on a tranny than drag racing. Jeff

Id agree, pulling is a lot easier on a motor, Although i did see some pretty high boost numbers, and the tracks around here you will pull your engine down at the end if your geared right, i managed to completly expand a set of big bellows, the same ones Rick puts on his up pipes, i could never expand the aftermarket ones with the twins drag racing, but i had a pretty hard season of drag racing on my cut pistons too. When they fail ill def go forged, if i get another season out of them ill be happy, it sounds like some forged pistons dont get much more than 2 to 3 seasons.
Mine is not tore down yet. It will be in the next month or so.
We are down on compression a bit and I'm just assuming it's the rings.
I'll post up what I find after we get the heads off
I got three seasons on a new set of OEM cut LB7 pistons with 16.8:1 compression. During the pistons third season (2009) I torched a hole in one and a couple months later I cracked another one. I think the cut cast pistons will only last only so many hooks, 1/4 mile runs and WOT passes.
Talk to Fingers. He has some testing and stock pistons are actually WEAKER when delipped/cut. Also there are people staying with higher compression pistons and having some very good luck. I dont really know why everyone assumes a stock cut/coated piston is the way to go?
the way i look at forged is if you want a race truck DONT try and use stock pistons that are not intended for racing.....no matter what you do you still have a stock piston JMHO
I dont think anybody is saying they're the way to go, the debate here is wether or not the 2k plus is worth it to go forged, and what brand of forged pistons to run.
Stock pistons will last more than 8 passes tho.
Sorry Rob but ive had well over that
Besides I cant afford stock pistons
Pistons
Rob, First I didn't mean you were not making any power because you are making a lot! Anything can be broken in short order is something is not rite. It's just crazy sometimes to think something making 1000hp will last a long time. Take any motor and make 3 times the power and see how long they last. Jeff

Oh i didnt take it as that at all, i was just joking around! I want to go with forged in my motor, im just not in a hurry to do it. If i can get 3 seasons out of cast pistons, (which im not saying that will happen everytime) what would be the benifit of going forged seeing that some are only getting 2 to 3 also? It seems that Arias are holding up better than that, so that might be my option when i go that direction, but if its not broke, im probably not going to fix it.
Any more info on this? I seem to be hearing more and more about trucks running stock un-cut pistions
Of course they are. You are removing material, that some engineer got paid big bucks to put there. I don't mean to rain on anyone's parade, but come on.
