Ok guys. This morning I pressure tested the boots and intercooler. No real surprise there. Some small leaks but nothing earth shaking. I know that all leaks matter but there was no real difference after we fixed them. So we moved on to plan b. We swapped over to my brother freshly rebuilt (and benched) pump today. It seems to move through the low rpm faster but the mid to top is still not great. I will say that his pump pulled much harder than mine did so my pump will be going to Seth soon to get worked over. I feel that today was a slight victory because we determined that my pump was defiantly hurting the low rpm power and responsiveness. We also checked out the waste gate and sett it to open a little higher.
But, even after saying that it is running better, I have to tell you all that it is still not even chirping the tires a little. Nothing. not in 2nd, 3rd, 4th... The full set of my bald testing tire are on it so, Fellow Dually owners, CAN YOU SLIP YOUR TIRES? Because I cannot. At About how many HP do duallys start to have traction issue on dry pavement, at 500ft above sea level, with bald tires, on a 75 degree day?
Now that the truck is not so sluggish down low, I am thinking that it really might be a good time to get a nice set of DV for this pump to see if it changes up top.
With this new pump (my brother's), it really feels like it would take off if it just had more fuel through the mid and top range. I could only manage like 35 psi in 3rd before I had to shift and lost it all.
The only things we haven't swapped out yet is the dv and we are still using the super b special. I am half tempted to just slap the compounds on there and see if that changes anything.
