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

Rip Ed... glad i got to chat with him recently.

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.

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.

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

Im offended......

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

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.

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.

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

that offset Grill looks horrible. like it was a mistake.

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.

I think There was a option for a wider bench passenger seat in the R model. This may be it?
