  2. you cant have different ratios in the same tandem. assuming you have 11r22.5 tires 3.87 ratio will get you to 70mph at 1750rpm (68.72mph @1700rpm) 4.17 at 1700rpm with a 12 speed will put you at 64mph
  3. Rip Ed... glad i got to chat with him recently.
  4. from what I know You can mount a used R model cab air suspension. or if the DM sits up higher look at a superliner air bag set up. Biggest issue will likely be mounting the lower bracket to the frame. I did a air ride kit upgrade to my RS700L I used a superliner set up as my cab sits up high. I had to fabricate up lower mounting as my fuel tank brackets were in the way.
  5. I was asked I think Trump should run again and I said no. Not that I did not like him but for what he and family had to deal with the last 4 years, no Person deserves to go thru that again. Yes Id support him again but I dont blame him one bit if he enjoys the rest of his days out on a golf course.
  6. Ed I hate to think your leaving us soon. I think I can speak for all when I say we are all glad that we got to share the many years of stories and topics of help with you. If I can just ask one favor from you . Please make sure to look down at us from time to time and give us a sign. Because I know there will be days we will be looking back up at you. As my grandfather once told me when his end was near. "Words dont always need to be spoken when you can feel them in the air." Take care my Friend
  7. I used a commercial grade carpet entrance mat with rubber backing. cut it to the shape needed. cost less than $50 and helped quiet the truck at the same time
  8. you will want a 285 turbo. We run a 237 at work and at best its around 15 psi of boost where my tip turbine pushes 25psi.
  9. I messaged him about a month ago and he said he was bed ridden and not doing great. He was thinking about all of us and was happy to know we are too.
  10. Lots of odd ball stuff the more i look at it. the engine bay looks crowded how it was layed out with the tip turbine filter and intake set up. way more troublesome to work around that engine. The passenger side air tanks and battery box are missing and the air tanks were moved to the other side. The passenger side fuel tank is much larger than the driver side and its moved forward. The driver side fuel tank is smaller and has some sort of filter between the batt box and fuel tank. Extra short rear frame the under cab exhaust routing and muffler mounting is not cab moun
  11. that offset Grill looks horrible. like it was a mistake.
  12. you said you dynoed some of the VmacII E7s and they would put down 20% more than advertised. was this with the mechanical pump and injectors? The full Mechanical E7 macks I have driven always outperformed the electronic versions. They pulled and you could feel it. the electronics were all very sleepy. I know the later E7 may have been better on fuel but they were guttless in the hills.
  13. I think There was a option for a wider bench passenger seat in the R model. This may be it?
  14. I can tell you that the newer trucks are nice and comfy, quiet and soft on the inside but they will take you to the bank every time the check engine light comes on and has to be dealership reset or has a emission related issue. Seams 80% of the problems with new macks (and every other truck mfg)are electrical or emissions related. I cant give you all the specific years to avoid or what years were prone to what failures but I hear the same basic issues repeated here. someone with detailed info should chime in shortly.
  15. YES IT SHOULD. put a superliner air bag under it and you will thank yourself.
  16. WELCOME TO THE ELECTRONIC E7.. they just lack power and are sleepy. you will need injector upgrades and possibly a ECM tune to get them to wake up and run like they should. I have only driven one E7 that performed well in stock form and I dont know why it was better than the other 10 I have driven
  17. a 300L is a low RPM motor that has a max loaded rpm of 1750. you can pull the pump and have it re-calibrated to 2100 RPM. for a few $100 bills....it will then be a 70+mph truck. and it will drive better than that junk 1750 spec.. you will burn more fuel but it will drive like it should
  18. ok great i will look for the housings that accept the rd style lights as that can be found in led as well.
  19. I want to put some LED lights in the CH truck I drive at work. not looking for just a bulb upgrade. im trying to figure out if this SBA CH in the pic used a factory housing without the clear lens removed or if there were different versions of housings that may have offered a square halogen light that was recessed. Thanks for any help.
  20. this was my first time out for a drive in it in about 6 years. it was good to get out for a 30min cruise with another truck nut.
  21. I was using gulfway but switched to Hagerty... Gulfway claimed I missed a payment and they would not be able to cover me even after I expressed I would pay for the hiccup...I was not aware of the issue. I had recently moved and think I forgot to change my billing address. I had not used the truck last year but was willing to make it right and pay for my mistake... they still did not want to work with me so went to Hagerty. too bad as they were good to me for many years.
  22. The truck is very clean. Has a 3406 400 Cat. she turns heads for sure received_214592666501212.mp4
