butchs18 Posted January 24, 2013 Share Posted January 24, 2013 Let me give you a little history about what I have done in the past two years:When I bought the truck, it was a 330/350 E-Tech Engine, so I decided to have Mack upgrade it to a 355/380 after reading post on this web site which was a big help. The upgrade gave me 1560 ft. pounds of torque at 1100 rpm's and 380 horse power at 1600 rpm's. Then, I decided to go up to the 400 horse power upgrade, which at the time I didn't realize that it would drop my torque back to 1460 ft. pounds. Later in the year, I decided to have Mack upgrade to 427 which would give me the 1560 pound of torque back. I already had the right turbo but needed the injectors that I have not installed yet. So, when I pulled my truck into the Mack shop it would produce 27 pounds of turbo boost with the 400. Now, when I took the truck out of the shop after the 427 upgrade, I only could get 22-23 pounds of boost. I was very disappointed. I haul bulk cement with my truck and gross 80,000 pounds and haul in the mountains of Tennessee. It seems like Mack punishes you every time you upgrade. What would you recommend I do next? Change injectors or put the Blixton 200 on the truck? The last six digits of my vin. # is: 123854I appreciated any help you can give me.Thanks,Butch Quote Link to comment https://www.bigmacktrucks.com/topic/29582-2000-mack-ch613-power-upgrade-to-427-very-disappointed/ Share on other sites More sharing options...
Mackpro Posted January 24, 2013 Share Posted January 24, 2013 Yes, something went wrong. Did they pull the camshaft out and put the off-set key way on the cam gear?

Mackpro Posted January 24, 2013 Share Posted January 24, 2013 when I get to work Ill look at my HP upgrade chart and see what turbo, injector and if cam key way does need changing. Usually on the 427-460 ETECH (non-CCRS engine 2002+) you have to install a off set cam key-way to prevent over heating. And with your VIN I can see what datafiles have been downloaded to your truck, but the mack dealer website is down tonight for some reason.

butchs18 Posted January 24, 2013 Author Share Posted January 24, 2013 Mack did not suggest the cam key change .... only turbo and injector change ... the turbo I already had. Sure have lost horse power. There's no way that it has 1560 foot pound of torque. The 400 that I had will outpull this 427 hands down.

butchs18 Posted January 24, 2013 Author Share Posted January 24, 2013 Is the E-Tech Engine and the E-7 Engine the same? The tag that they put on my motor says E-7.

Mackpro Posted January 24, 2013 Share Posted January 24, 2013 We tried boosting a RD from 350 to 460 with out changing the cam key way but it overheated in the summer time. We did a the same on a CH that had a new radiator and a air fan and it barely survived a summer, we later changed out the cam keys.

Mackpro Posted January 24, 2013 Share Posted January 24, 2013 You should be getting around 30 psi of turbo boost now. It shows your engine ECM has been set to 427.HP. However doesn't look lke no one has updated the vehicle ECM in a long time. My screen shows it could be bumped to the "Step 12B" program. I figured while the truck was there they would have done that. It would help alot on throttle responce but would not keep you from getting the correct boost pressure. Also do you have the part numbers of the turbo and injectors they installed when they went from 400HP to 427HP?

butchs18 Posted January 24, 2013 Author Share Posted January 24, 2013 They did the upgrade yesterday. Did not install injectors yet. Turbo # 5153m. I was hoping the 427 upgrade would give the 1560 fp of torgue back but now has less then the 400 Quote Link to comment https://www.bigmacktrucks.com/topic/29582-2000-mack-ch613-power-upgrade-to-427-very-disappointed/#findComment-159536 Share on other sites More sharing options...
butchs18 Posted January 24, 2013 Author Share Posted January 24, 2013 I think that going back to the 400hp and then changing to the 427 injectors would give me what I need Quote Link to comment https://www.bigmacktrucks.com/topic/29582-2000-mack-ch613-power-upgrade-to-427-very-disappointed/#findComment-159538 Share on other sites More sharing options...
Mackpro Posted January 24, 2013 Share Posted January 24, 2013 The download and turbo upgrade are useless with out changing to the bigger injectors, gotta change the injectors , their probably more important that the turbo. The turbo number we use is631GC5173MX on the 427 and 460 but the number you gave does cross over and will work. The new injector # should be 736GB415M2X. The 427 and 460 HP all use the exact part numbers on everything ( except the 2002-2003 CCRS engines) , the only difference is the download. We always shoot for the 460 cause its the same money.

butchs18 Posted January 24, 2013 Author Share Posted January 24, 2013 (edited) Thanks for the imformation & thanks for guys... like you... for helping owner operators like me trying to get up the hills faster. You are right on the money about the upgrade without bigger injectors installed. Had the truck to mack today,They checked the upgrade, said everything was ok just need injectors. I'll install them in a few days. I did try for thr 460 upgrade but mack said my tranny was not strong enough. check out the attachment.

They are just covering their ass if something goes wrong. And it mostly for warranty reasons so if you do blow a rear axle that was rated to low for the HP and try to get it warrantied. We let the customer know what Mack said and let the customer decied if its worth the risk. 99% say go with it. Its not like these engines are every gonna put out 2250 Ft LBS of power and tear something up. We always tell Mack, yea we changed the rear axle or clutch or whatever ( as long as the customer knows) and they crank the HP up.

I know a lot of guys that have done the Mak upgrades to get more HP only to be dissapointed after spending a fortune. I say go spend a little over a grand on a computer reflash and a set of injectors and if you have a 427 up turbo rock on and watch the pyro so you dont melt it down on a long pull, there is a lot of hp in those ecm's.

I will get you my vin # and turbo #. I am running 300h.p. injectors right now. I changed motors(through a rod out block) this one was used out of a garbage truck. I used my ECMS and electrical harness, turbo but did not change injectors, I still got my original ones. Used motor was rated at 300h.p., I do have that ECM as well.

rsb502 Posted January 26, 2013 Share Posted January 26, 2013 Gotta get the fuel in there, actually changing to bigger injectors would have the capability to make more power than all the rest.

keg1 Posted January 31, 2013 Share Posted January 31, 2013 I also have a 2000 CH613 with a 400 that is sick. Ive had it to 2 different Mack garages and another garage thats good with Macks and was told you cant do anything to turn these up. So where do you guys go to get this done? I live in northwest PA. They tell me its as good as it gets but my Superliner with 350 runs circles around it. Any help?

WILL THEY WORK IN MY ENGINE?I realize your going with all Mack factory parts, call Antrim Diesel in PA to get some info from them, believe it or not buying aftermarket stuff is much cheaper than OEM in most cases and will make more power if you get the right parts. I know several people have contacted Antrim for their power upgrades on BMT ask around most I have talked to are very satisfied with the results. 717-597-7963/7964/7965 Quote "Any Society that would give up a little LIBERTY to gain a little SECURITY will Deserve Neither and LOSE BOTH" -Benjamin Franklin"If your gonna be STUPID, you gotta be TOUGH" "You cant always get what you want, but if you try sometimes you get what you need" Link to comment https://www.bigmacktrucks.com/topic/29582-2000-mack-ch613-power-upgrade-to-427-very-disappointed/#findComment-160763 Share on other sites More sharing options...
Finnish mack guy Posted December 6, 2016 Share Posted December 6, 2016 i have a mack etech 12litre with 480horsepower originally. No i have changed eup:s and injectors to bigger ones and an holset hx55 turbo. We made a new software to it on a dyno . Now it's pushing 611rwhp 3110newtons on 1600rpm. The difference is outstanding and performance and fuel economy is better Quote Link to comment https://www.bigmacktrucks.com/topic/29582-2000-mack-ch613-power-upgrade-to-427-very-disappointed/#findComment-354180 Share on other sites More sharing options...
