so you dont have a Mack shift knob with the range switch in front and a gray colored splitter on the left side, that is horizontal?   what year are we talking about here?  

I do. I want to change shifter but I see no aftermarket support for it. All the designer shift knobs are for eatons

Folks on here know more than I do.  But, I would assume you could change over to an Eaton knob.  As long as the air pressure goes where you want it to go, I don't think it matters what the knob looks like.  I mean, you just have a range shift and a splitter, right?  Shucks, you might could even go old school and separate them into 2 selectors; one on the knob for the splitter and one on the shifter shank for the range!

A friend of mine did two old school splitter valves on 8spd.

I have an 18spd maxitorque. I want to change shifter head but splitter goes up and down. Not side to side. Does anyone know where I can get aftermarket shifter or can I switch to an eaton style shifter knob?

hell,  if you have mack build it, I bet $32,000.00 is going to be the final bill.   jojo

Cat platinum rebuild. I can buy another rd with that 💰.  I love my rd.

Mack seems to be very high on their internals. A lot of cat guys use PAI too I think for that reason. Haha 

Your absolutely right. PAI has come a long way. I believe some of there stuff is better than oem

673 was a 237 ,250 turbo.  I've seen guys take them to 300 but not much more than that. 675 I believe is a 300. I know you can take 675 pistons and put them in a 673. 676 I believe is the tip turbine and I'm not sure what changed internally.  I do know the 676 comes as a 350hp as well as what they call a 285/315.

Hopefully someone else will chime in who knows a little more.

Mack prices are insane. 9200 full inframe with heads. Pistons treated. Pai.

Mack wants 11k for inframe and they want the old pistons back. ( I believe sleeves too). That price didn't even include heads. If I have to use Mack parts; mind as well own a kitty kat.

Sounds like you may have found your issue, good to hear!

So far. Im to look under intake manifold like jo suggested and then some filters and see we're we at after that.

yes sir.. I'm Ok..  I have built more than 30 of these engines, and I have many 'correct' engine tools for E-6 and E-7/E-Tech..  I hope to build more engines in the near future, because new trucks are insane and a lot of guys are trying to buy older trucks. I can build an E-Tech at a reasonable price. I have to use PAI parts to keep it realistic, but they run.  Ive done a few that way..  Jojo

We won't by any new trucks. There is 7 etech between me and my friend. One vmac and one cat. The price for trucks is insane. Doesn't pay just to satisfy the driver. These macks make the same money. I look for good rails and at least 400hp

I assume you have a 2 pc. intake manifold..  if not look for a blown out gasket.. i have seen more at #5+#6..  do the best you can to look under the manifold..  jojo

I will do. I definitely found two boost leaks already. It's suppose to warm up this week so I'm gonna dive into it.

PAI is actually very good from what I understand. A lot of very good engine builders use there kits. Sorry bluie dm for us kinda hijacking your thread. 😕

I love it. I can talk to you guys all day. I grew up in dm. I'm only 42. I say a 673 motor. None of my friends who drive even know what I'm talking about. I say quadbox. They say they saw them on YouTube 🤣🤷🏾‍♂️. My grandfather had 5 of them. Way out of my age group but learning on one of them made me a driver

We just did an e7 with PAI. I was impressed with quality. A lot of there stuff is coated which can take a little more heat. Did exhaust manifold from them as well. Was a bitch to get started with all the air in system but she is running great.

Looks like your in New England area with those patriots stickers 👎🏻 Make sure that road salt isn’t beating the hell out of your radiator/intercooler. We see a lot of that down here in PA. A lot of radiators get replaced….

I brought trick from New England. I live in N.Y. same deal though with salt. Truck has brand new frame rails. Thatz why I jumped on it.  I'm a cowboys fan. Radiator is leaking now

I love a 12 speed mack! Eaton 8ll is good but I have found they have 3rd/7th gear sliding clutch issues

 

 

Yes. 3rd and 7th. For what ever reason. Seems really common in Rds

Ahhh double wall frame, we just got rid of one. Awesome truck!

Yes. I put the 4:17 in there. Forced me to use deep reduction a little more but she was a runner. It was time for engine rebuild and frame. It was more of a time thing. Can't find no one to drive an 8spd never alone having an old mack 12. Easiest; straight to the point tyranny. 

Understood 

I sold my 97 e7 400 with a 12spd and 4:17 rears. Had a bad frame but dam. She was a runner.

We BS Alot Here!  you know! 😂

It wouldn't be fun without it🤣

It donest have any blow by. It has a new cam and few other things in that area.  Does anybody know what turbos they replace them with. It's already a borgwarner so I'm assuming the same one if it was weak?

Also cold air is going to provide more power 

True indeed. Our turbo cars run amazing in the fall at night😁

Timing 

I'm assuming in the computer. I read that offset key for cam was in all etechs after a certain point.

Just now, Onyx610 said:

Start with getting an air filter and a filter kit (should be done anyway) and then put a load on it and see what happens. If you still have the same results pressure test the charge air system and check for exhaust leaks. 

I am. I hit 30lbs one time and truck is not loaded. Changed hot side boot from turbo to intercooler. Definitely filters tomorrow. 

Well it's a 2000. I haven't ran it loaded. I guess my confusion comes in is this. I've driven quiet a few e7400 with s400 on them. On a cold night loaded I've seen 32ilbs of boost. It's only suppose to be a 400 tho. 95 percent of the time 28 -30lbs of boost. If 30 to 32 is it for a 460; how is mack making the extra 60hp?

Ok.... I'm going to throw out, what may be a dumba$$ question... do you here this info on the C.B. Radio?  or from mechanics?   sorry,  I started my 'Period' today so I pull out some B.S.    Jojo

🤣🤣. No jojo. I read it hear.
