  1. If my grandfather had an old quad that ran 62mph. That was flying then.
  2. Family had 5 70s dm800 673t One 85 685sx with a 675 tip turbine with a 6spd. It would do 67mph. But for the setup.... pulled like a savage.
  3. Yes. Seems to be pretty accurate too. I think I'm gonna do 4.17. If it was a bigger motor I wouldn't be so concerned with the loss of tq but I think 3.87 is gonna be a bit much in terms of loss of pulling power. So now that I have the mph figured out let's talk about loss of pulling power. I guess experience is gonna have to answer this questions.
  4. 3.87 is a big jump from 4.17. I was going to do 4.17 but 3.87 would be great if it doesn't kill the torque all the way.
  5. If I go 4.17 with 78 final with the 11r 24.5 where would that put me
  6. 5th gear is 78. Yes it pulls very well. Have a little timing thrown in there as well. Problem is we( as time goes on) are running more highway. At 65mph its up around 1700rpm ...1800. I want to get those rpm down. I would also like to be topping out around 80mph. It's not necessary but I would like. As I said before...the tires are 11r 24.5. Again. Any help.is appreciated
  7. My concern is loosing a lot of pulling power. It pulls well for a little 400. I know I'm gonna lose a little but I don't want to lose whole lot. If it was a cat.. no problem 3.91 here we come. I've ran 120k with that setup but it's a mack. 11liter. Trying to keep balance.
  8. Not quiet following. It's a dump truck. They still go off road. I have a rear going so I figure try to kill two birds with one stone. I'm unfamiliar with that ratio because all the macks I ever driven were quads, 6, and 7spd and the rear ratios are up in the 5s so some advice is still needed. Are you saying the 12 doesn't go good with 3.87... what are you saying
  9. 11r 24.5. It's also a dump truck so I kinda feel I'm gonna lose the bottom with a 3.87 rear
  10. Right now I'm running 4.42 in my 97 rd with 400 and 12spd. Problem is now I'm running the highway and I don't like 65mph at 1700rpm. I would like it to be at 70mph at 1700rpm. I would like to run 65mph at 1600ish if not a little lower. Will I achieve this with a 4.17 ? How much bottom end I'm I gonna lose? I'm running 11R 24.5. Also can I run to different ratio rear ends like a front 4.42 and a rear 4.17?
  11. There is no power to box.. still very bad draw on batteries.
  12. ok...with ground wire disconnected from all batteries. With test light hooked to ground terminal on battery... I'm getting power at three wires attached to left side of box. Is that because its just searching for a ground at that point? If i hook test light to ground terminal on battery snd then to ground wire thats suppose to be on terminal i have power. If i disconnected that box i lose the power on ground side. Does that mean that box is bad. I also have power to wire tree on all wires on left hand side with key off. Relay in dash is wrking to par. Cab fan turns off with click in dashboard
