I have driven a lot of heavy spec CL's but here is my old 2000 CH. It was double frame, 14,000 front, 46,000 Eaton rears on Mack air leaf. E7 460 with an Eaton 18 speed.

One of the smoothest riding and best handling trucks I have ever driven. Also the best factory headlights I ever had. Never even had a need to use the extra 100W auxiliary lights.

It just inspired confidence driving it. No matter if it was white outs or freezing rain, it never did anything that made you feel uneasy.

That truck sure worked good. Used to haul bark and logs with it. It was like a bulldozer. I had the temp sensors ripped right off the diff pots and it never got stuck. I can't explain it, but that truck just worked better than most I have had.

 

The downfall.....the E7 full of casting sand and electronics gremlins. When it decided to run though it pulled good. I ran with guys that had same loads and trailers and they had Series 60 500's and 475 Cat's. Yes they could pass me on the hills, but I could keep them in sight.

Yea i agree about the smoothest and best handling truck I've been in. FL classic, 379, t800, crapcadia....all don't compare.

Do you have a gauge for boost?  What are you reading on those long pulls when pyro goes up?  My boost snaps up to 35 PSI and stays there.  Rochester's turbo is $2,200.  Well worth it.  Have you smoke tested the truck since the new injectors?

Could of got a s475 (1.32ar on ours) for 700 or less and pull 42 or more psi. On the 93 with stg2 injectors and blixxton it pulls 35 @1250-1300 and 42-43 @1400

 Mack Tech pointed me to this thread 

I ended up using his same turbo which I believe was a borg warner S467 with a billet wheel.

Its a little bigger than the s300 and definitely spools earlier and flows nicely.

Im no expert but the larger exhaust manifold and GR pipes in conjunction with the turbo and injectors from K&S have really made this truck a pleasure to drive

 

 

How much boost you pushing with that s467? On our 93 with the S475 (171702) we see 42 psi. Have you considered getting the blixxton 200? We have on the 99 460 E-tech and boy it brought that baby to life. 

https://youtu.be/LMps1A4uf5Q ok reviving this thread since i found out how to upload vids. If you go back and re-read you'll see what im talking about but the short of it is this

Factory 350 vmac1 with 16.9:1 compression. We went with the lower comp 15.3 pistons and stage 2 injectors from Rochester + blixxton. It never smoked/missed before the rebuild and bigger injectors. And it only smokes under no load or light load conditions. 

We swapped out the pump and econovance to rule that out and still does same thing. Checked each injector and they're good also. Were going mechanical anyways (pump being built now) but figured a video would help with my explanation

What's the specs on the turbo you got? Looks like it will flow a ton better and keep egt's in check

I don't believe Hannaford or Hogan had Mack's before.

Yea i can't ever remember seeing a Hogan mack until now

I thought the ch had a set forward axle That one looks like a set back like a cl?

You could get them in either set up. The 99 we have is set forward. Imo the set back axle is a better riding setup but the set forward is better setup doing off road/oilfield work

We've been using Gliptone polish with good luck. Have coarse-med-fine-ultra fine and good ole fashioned elbow grease and micro fiber rag

Cool video. Out of all the Ch styles i think the mid roof with fairings/cab extenders looks the best. They don't look right w/o the visor. 

Just got got done giving the a good wash and polishing 

UPDATE. And long post

Monday were taking a ride to Trovei and sons (huge mack graveyard in port jervis ny) to see about getting pump, lines, pedal, linkages everything to convert the 93 to mechanical. We found a local guy that does nothing but P pumps. From stock rebuilds to sled pulling 12 valves. My dads already been on the phone with him, explained the setup were running. Running the 15.3 pistons with big injectors and the s475 he figures lock it up around 25-26. He mentioned going flat top plungers and maybe different cut delivery valves. Either way the pump is gonna be rebuilt. 

Hooked up the prolink while pulling a loaded wagon. Says it has a 400 file in it. Anyways under full load it was getting 16-17 right on point for the 93 400 specs. The 350 file has 22 deg of timing full load and the 300 has 25 deg at full load. We tried getting cook bros mack in Binghamton ny to see about putting the 300 file in it. Going down in hp you think they would.......nope. 

Another strange mack quirk. The 1993 tune up manual we have lists specs and pump configuration for all E-7 and E-9s for that year. The 250 to 400 E-7 all have the same compression ratio of 16.9, but in most other literature it lists 375 and up 15.3 and below that 16.5. We hadn't heard of 16.9 until that tune up book. Bear with me

So thats a big jump 16.9 to 15.3 plus adding big injectors and the huge S475. To compensate for the "extra" space and more fuel in the combustion chamber shouldn't the timing be bumped up more? I would think it would need to be and the pyro is telling me that too. The exhaust heats up faster than it should on a pull. Almost like before the inframe with stock turbo and the blixxton.

16-17 degrees is too far retarded for the setup we have now. We would love to stick with variable timing vmac but so far no luck getting a file from VoMack. I know someone here works at Watts, forget who but if i give u a vin can you try to work your magic? We'd be down there in a heartbeat. 

Thanks in advance and ill post pics of the 93 tune up book if you guys want. It even has the data file # and all the tech specs on the diff hp levels for 93

Possible!  was the pump redone?

Got one online along with an econovance, both rebuilt. 

Since it was originally a 350 from the factory could the data file have something to do with it after upping the hp and going to lower comp pistons? The thing is that it only studders/smokes at light or no load. Once you step on the peddle it runs like a pissed off dog. No blow by and we haven't had to add a drop of oil on both changes so far

Ah! my mistake  So In my opinion you should be looking into an injector with bad or low cracking pressure or a valve hanging up! check your valve set first! does the engine have much blow by?

No not even 20k on the inframe and injectors from rochester. Possible we got a bad one?

Yup I agree haven't ever seen much improvement on the smoke issue advancing the timing unless it was it was a retarded blu colored smoke ! in this case he claims to be getting black smoke in which case if the smoke don't clear up with 38 psi boost something else is a miss!I However I  believe if I'm reading this right the idea is to get a quicker spool and still keep that nice boost out put!

No its the blue nasty smoke with a miss at no/low load until you step on it and the timing advances on the 93. 

Edit: it will roll coal until the turbo catches up but it clears right up 

The turbo question was for the 99 etech

You may be correct however.In my mind the software assumes you’ve set your base timing correct so you set it 3-4 advance it would be adding.  to the twenty or so it adds when the econovance operates I could be wrong but in my mind it works in that fashion!🤔

Yea we found that didn't really work either. Well not like we hoped, might of got a few degrees 

On 4/28/2019 at 9:40 PM, 880joe said:

How much did the blixton improve the 99? Did it improve fuel milage and power or just power?

Its no 30% more horse like they claim. Maybe +60-75hp and 0.3 increase in mpg in the highest setting  Its not user friendly either imo, ill post pics later when we go into work. Directions could of went into more detail.

David if you have your truck reset to a 355/380 you will have 1560 torque same as a 427 instead of the 1460 you have now with the 400 setting

Or 380/410 that has 1660. 5173M4 im almost positive is on our 99 460. That turbo was put on a ton of E-7s as a factory replacement....don't quote me on that someone else will have to verify that.

Fooling v Mack ! You could try tweaking your base timing two or three degrees and see how it is  that will advance you to 24-25 under a pull , ,changing to the mechanical pump means a total line swap ect

No emmisons or smoke checks out here in the woods of north east PA. Hardly ever get on the big road. Running frac sand locally

Yea my dad is set on going full mech. Lines are about 900 give or take. We did tweak the base timing 3-5 degrees and didn't make a bit of difference. 

@AZB755V8 we don't want more power necessarily on the 93, just want it running right. Its hardly broke in with ~20,000 miles on the rebuild. Under light load or no load it studder's and smokes until you step on it and the timing corrects itself. I've been running it in the 1400-1800 range. I don't want to stress the bottom end and lug it. Not to mention the ancient RT double over .62   13 is only rated for 1450. 

Could be gremlins possibly in the harness somewhere? We swapped injection pump for a rebuilt one and a rebuilt econovance to rule that out, New TEM and pretty much every other sensor along with the blixxton. The pro-link with cartridge says no codes. 

The pump guy were going to has a very good rep. He'll know how to set it up to run optimum. Were both happy with the power it has now. Pump guy just got done building a pump for a 2500hp 12V. He mentioned something about flat top plungers and quick fill cam? It makes sense your not looking for max volume. With higher pop off pressure fuel would be going in too late and not getting a proper burn. 

Thanks for taking the time to reply, really appreciate it. I'll have my dad read over this tonight  

We found a mech 350 entire engine/pump/lines/manifolds for 1500$ a hour away. who knows what's wrong with it but they say it turns 360 deg.

Just did a quick check on the BW 171702. It is available new $759. Just get it from a turbo shop, it will not be Mack but you can tune it. It comes with a 1.32 A/R turbine housing just as the one you have. If yours is a bit laggy go down to the 1.15 A/R housing and it will pull better than your 93. Boost will come on at 200-300 lower RPM's and it may make more boost than your current BW475 so be carful. Total with 1.15 housing should be around $1000. Have fun!!  

When the boost comes on it hits like a train. Most hills on 81 in pa it will pull it in 8th L @65+mph loaded 70k +. If only it were a cat or 60 series the info would be all over. 

My dad is going to put a mechanical pump and get rid of the vmac1. Since we dropped the compression from 16.9 to 15.3 (the 93 tune up book says it 16.9 but almost every other site says 16.5. So IDK) the timing is off. It needs to be advanced a little more with the big injectors, turbo and blixxton. We heard about a resistor to fool the intake temp and supposedly it will help advance it a little.

Edit: finding someone to work with us isn't a problem. Its just getting info on little tweaks/hp mods is the hard part. We do all the work on the trucks, don't trust any new "mack techs". But we did manage to get the local cook brothers mack to sell us non vin low comp pistons instead of the oem. Wanted mack not aftermarket. 

The reason were going to a mech pump is to get the timing right. Too far retarded now. It shouldn't be rollin clouds of coal like it is now and even with that huge turbo the pyro will get 1050 on a long pull. No boost leaks any where, checked and checked again. New CAC less than 20,000mi on it same as the inframe.I know advancing timing will bring egt down and itll run better. Unless someone knows how to fool the vmac1 mech is the best option. 

Were looking for a R or superliner to be our spare truck. By the end of this summer will have the 99 the same paint scheme as the 93

Ok thanks that's what I was wondering. I didn't know if it was a mack specific exhaust housing or not. For the work we do the 1.32 is good all around. Sees 32 by 1250 and 42 on a real cold day. I haven't talked to anyone running the setup we are yet. Before the summer is over we'd like to have Antrim dyno it

That grey one is really sharp. 

It used to be about 2ft + longer. Someone shortened it up before my dad got it. 

Not 100% sure but I think its the s400 series with a 1.15 or 1.25 ar. Not sure on compressor specs. The s475 is 75/96mm. 

If it helps any you can take the aux off an old RTO like we did with a 14613 and put it on a RTX14609B giving you .62
