I have been to 3 pulls this year ever one of them with both attemps I have bad wheel hop right away. So bad I have to stop. On hard clay tracks it isn't even wheel hop I get the whole truck off the ground, I'll see if I can't get the videos up
Anyway I have been listening to people about tire pressure and this and the other and watching other guys in my class with trucks like mine to see what they are doing and trying to figure this out but I get no where. Not trying to sound cocky but I think it is cuz I have alot more power than the others and my wheel speed is greater, I'll put up a video of another truck like mine to show what I mean.
I have an 07 5.9 with 1" stops thats the rule 6 speed pulling in 4lo
The video of the other guy is same deal 6 speed 4 low. This guy has dynoed 552 at wheels horse.
I haven't dnyod so I don't know what I have but I have done better than him in the past. If I had to guess with what I have done I am think over 600 horses.
The first video is with mud tires 30psi in rear 25 in front, Yes its low but I ran that last year and did really good, I also had less power though. Also in this video and the 2nd one I had 2 extra plys in the rear springs. I took them out for the 3rd thinking that with the stiffer springs I wasn't fully loading the stops.
Second video is new bfgs with 50 rear 30 front
Third is bfgs 50 rear 30 front but back to stock rear suspention so that it hits the stops better, so I was hoping anyway.


I have no clue anymore what to do besides take the stops off. I didn't run the stops last year and didn't have any wheel hop issues. I don't want to take them off though cuz I think with them on and my truck connecting the way it should I will be able to pull harder futher.
I guy in a class above me with a truck just like mine only bigger charger and sticks I'm sure, Its a very good pulling truck, anyway he told me to go to 70 psi in rear. He has seen me at all the pulls and said thats what he would do. I am thinking about it but not sure what to run in the front, He said the front doesn't seem to really matter however in the videos it looks like the front comes up first most the time.
Tires are 315's maybe since they are bigger I do need the added air pressure??
I'm about ready to just call it quits on pulling, So frustrated!!!!:bang

Videos should be up tomorrow

and yes I do have traction bars
 
I'm no expert but i always run between 70 and 80 psi in the rear tires i tried 45-50 psi one time and i had really bad wheel hop on the video you could see the tires flexing and as they would unload it would make the truck bounce up. I at that time had rules of 1'' of travel. I had no extra leafs or anything just the blocks. The sled will put every bit of down pressure you need on the back to make it hook to the track from my experince
 
I'll be honest. Wait to you see the video is beyond ladders I think. whole truck is off the ground. I mean you can see the bottom of the sled from the front of truck
 
The front depends on the track and horsepower of the truck a good starting point i feel is 25 lbs and go from there depending on track conditions
 
we used to run 18psi out here CA, but the tracks are sandy, loose for the most part, so Tony R's recommendation sounds pretty smart to me, but trust me on the ladder bars---I had mad hops until I put some 8' long ones on my truck and bingo gone---so if you don't have them you need them and don't build them out of pipe they need to be DOM or chrome moly---chris
 
if it used to hook up smooth last year and now it doesn't, which is how I'm reading your explaination, go back to exact setup you had last year and start there...

regardless, you are going to want traction bars.

your not kidding about all the wheels being off the ground ... it was nuts on your first run you had the front wheels at least 6" off the ground.

From the runs I saw at the buck and mason dixon It looks like you were side stepping the clutch, have you tried to ease into it? Also you need traction bars if you don't have them.

yea i was standing at the fence right next to him headed back to get my truck for the drags, u got some air under the front end when it hopped....but id say more air in the rear, but i cant even get into the shot out in stock class so what do i know :what:
 
I agree about the ladder style bars also. Last year i had a hook that the truck hooked so hard it started bouncing and bent my single bars to a u i built a ladder style set up and reworked the hitch a bit and after that. It hooked so go it started to flex the frame between the bed and cab and that to me means that you are getting the power to the ground. But im no expert so take my words for a grain of salt

do you have any pic's of how you mounted the bars? have you checked to see if there is any pre load on them?

I'm running a set of BFG 33x12.50's with 50 in the rear and 20 in the front and I came out of the hole very clean.
 
I was slipping it some in the first pulls and it did the same thing. I should have the videos up here shortly for you to see.
Hell the one pull I even got the tires rolling like they should be and 15ft into it bounce again
 
I do have bars. I bent the set I built 3 years ago really good on my first pull, so we built some bigger ones. I do have some pics of the old ones if I can find them. The new ones mount at the same spot though
 
did have two extra leafs in the pack, now it is stock leafs whith a small 1" block just to give me a little more tire clearance.
