this thread was very misleading

yea for a play truck it would be ok but for any soft off road work... good luck Im with Herb 80+ if the 237 can keep up. it will however get you back from the truck shows on time!

here in the US we had some GM and Cat engiens sneak into the long hood superliners R700 and RS700L cummins was the most commonly off breed engine found under the hood. I remember roadway having alot of R700s with 318 detroits

The old girl can get up .. nice video!

welcome back David.. was wondering where you went?

Most twin stack superliners I have seen had 90 degs at the bottom and ran under the cab to a Y pipe. the diffrence in mounting would be if the truck had an air ride cab vs solid mount. some stacks had frame mounted brackets wile the older superliners were cab mounted like the west cost R models had.. this is just what I notice. My RS700 has twin cab mounted stacks. the top of the mufflers are level with the rain gutter at the top of the cab. the muffler bottoms end about 14" above the frame hight. just about the min amount of space needed to get a 90 bend under the cab Trent

just a heads up. save your torn door panels and have them remade at a local shop.Alot of interior parts seam to be NLA from mack, I had one remade last year for around $80 looking good!

yea he posted this a year or so ago but its still fun to watch. I like how he backs all the way to the hill side to get the speed for the hill.

953 and 963 always liked them, 953 was good for small jobs and the 963 could load a truck real fast and push most piles down in just 2 passes.

nice looking RS looks like you took pride in her

some guys up here use a 3rd gladhand for the tailgate open/close operations on a dump trailer. ???

I think the mack gliders are done? I havent seen one in a few years? EPA might have killed it?

Rob I must say you live a intresting yet simple life.

best way to learn is too watch, listen, and then give it a go. Keep you ego in check and your attention on the important stuff your doing. I remember driving the first full day by myself it was a little wierd but after an hour I felt comfortable with all the basics. After a week I was in tune with the truck and withing a month I had discovered most of the tricks and was good at most of the tricky things that came my way. Good luck Trent

rob stop blaming it on the trucks you need rehab

or did you find a home?

the E9 was used in the Superliner,MH,CL, i think the RM and RD800s possibly the cruise liners as I cant recall? the older ENDT865/866 were used in everything from R700s,RS700s Cruiseliners,F models,C models B models I think some early R600 even had them? The E9 was a better design than the older endt 8xx models and was a stought engine if cared for. For real high HP some mods are needed to keep the main caps in place. also valve spring work is a good idea for High RPMs. I think the Detroit would be a lighter engine and because of the 2 stroke design it might be a better drag strip engine for as it seams many can wind those engine out pretty high and take advantage of larger RPM range. Compairing a V8 detroit vs the E9 for pulling ...Hands down the E9 has the torque needed to pull weight....

Thats the one I was thinking of... Thanks for finding it, I was thuming thru my WOT tonight but could not find it. Trent

the story that I think was in WOT? had a write up on what motors and gearboxes were in the truck thry the years of ownership. Also a few storys of running the truck out on the road with some risky runs etc... If you dont get a reply from the current owner look over at the ATHS you might find someone that remembers that mag issue. II just looked at the covers of My WOT issues and could not find it. It might have just been a write up on the internet that im thinking of??

-20 here this morning . I had to put my jacket on

i think wheels of time did a story on that truck a few years ago?

Intresting set up there theakerstwo. so that B model had an air to air,and the tip turbine with water core on that. thats alot of cooling there!! If my motor in the RS700 was slid back a few inches i could get the air to air in front of the rad but it would be to much of a PITA to move the rad back and engine back just for the Intercooler set up. what I notice with my tip turbine is that when im lugging around 1200 RPM in 3rd or 4th gear up an on ramp. the EGT temps climb to around 1000 Deg but as soon as the turbo starts to come alive around 1300-1400 the turbine winds up and brings the temps down to 850-900. I like the 1-2 up shift from a dead stop. First gear is to short to get the turbine going but 2nd does the trick. It sounds like twin turbos between the shits as you can hear both the turbo and turbine fan working together.

Thanks thad ! I couldent find that pic in my searches

Brandon you are correct the coldest air that passes across the core to cool the boosted air is that of the outside air temp. In the days of short WB trucks every inch counted. I assume Mack used the side mount charger as it was a compact engine design and the need for a front mount was not needed for the HP rating at the time. When the 300 maxidyne came out I believe is when the air ro air front mount was used. There was also a design on the 300+ engines that used a water core on top of the air charger core. this was a tipturbine but the core was taller to house the water core on top. The water came from the engines cooling system. because the engine water is cooler than the boost temps it helped reduce the intake temps along with the tip turbine air flow. water also carrys away heat better. I dont know how much better it worked but it worked and lots of people liked the 285 and 300+ motors.... If the water had its own tank to remove the heat it would have been a more complex but better design IMO. The air bleed pipe has a one way valve it allows air to flow to the turbine but it closes if unfiltered air trys to reverse back flow thry the turbine and into the engine this valve can also be adjusted to flow more or less air by "bending" the valve door stop. allowing more boost will spin the turbine faster as it has more volume to push it. the disadvantage to this is that it also will bleed off more boost its a catch 22 so to speak. an easy way to spot a 285 or 300+ is to look for the air cleaner. If it has 2 intake tubes that go under the hood or has a hood scoop on the passenger side near the turbo it might be a tip turbine. canadian macks alsi used twin tube on some air cleaners to draw in warm air so it could be either.? Its a neat design for what it does Trent

ill try to explain. the outside filterd air enters the turbo, then it is forced fed into the boost pipe that runs over to the side mounted charge cooler. there is a "bleed pipe" that comes off this boost pipe and sends some of the boosted air into the tip turbine. the rest of the air in the boost pipe goes through the cooler fins and into the engine to be used in combustion. the air that entered the "bleed pipe" enters the turbine, speeds it up under boost, and is ehausted to the outside air. As the other side of the turbine spins it draws in cool filtered air in and routes it over the charge cooler fins to cool the boosted air on the other side of the core. this air is also exhausted to the out side after it has passed through the core. the only air that enters the engine comes from the turbo and makes it past the "bleed pipe". I think it was the first charged cooled diesel engine but someonce can correct me if im wrong. They were compact and did not take up any more room infront of the engine. I think after length laws relaxed and bigger engines evolved the larger front mount air to air became the standard. Also to remove all that piping to perform a simple repair is a real PITA. Hope this helps?
