2000CL713 Posted September 28, 2017 Share Posted September 28, 2017 (edited) hi. im a new member here. been looking at this site for a few weeks now and though id join. i have a 2000 CL713 dumptruck with E7-427 and eaton 8spd. coming up on 600.000 miles. iv owned it for almost 10 years. just about every opt other then the wood dash and power windows. has all gauges. dual exhaust. alum air tanks. alum battery box covers. full length steps. dual alum 100gal tanks (think they are 100? cant recall). alum rims on 24.5 tires. lighted and heated mirrors.... and so forth.... you get the idea lol im wanting to get some more power out of it without blowing it up obviously (lol). whats the safe number to shoot for and how would i go by getting there? as in what things should i do to it upgrades wise. i been reading on there but its a bit confusing on what i can and cant do and what parts to use or not to use since some years and models need to swap this or that. any help would be grateful!

Mackpro Posted September 28, 2017 Share Posted September 28, 2017 (edited) Good thing is you have a regular ETECH engine. Better thing is your already at the 427 HP level. On the ETECH engine ( pre-CCRS and pre-ASET) the 427 and 460 and 460XT use the exact same turbo, injectors and cam key way. So really a factory HP download upgrade to 460 HP would be easy if you have a good dealership to work with. They can submit a HP change request via E-service. I dont know if Mack is still doing the 460XT program. We do lots of HP upgrades but now mostly on red motors.

880joe Posted September 29, 2017 Share Posted September 29, 2017 KandS diesel out of Schofield WI or Rochester Diesel out of Rochester MN both have better injectors that will get you more power Quote Link to comment https://www.bigmacktrucks.com/topic/51180-2000-cl-e7-427-upgrades/#findComment-381152 Share on other sites More sharing options...
2000CL713 Posted September 29, 2017 Author Share Posted September 29, 2017 I rather go the 460xt route if I can. What is all involved in running bigger injectors route? So I need a aftermarket computer tuned for them? How much power would I see above the 427hp?

Mack Technician Posted September 29, 2017 Share Posted September 29, 2017 You can injector swap with no other additions or EECU flash. K&S says 30 hp.

Mack Technician Posted September 29, 2017 Share Posted September 29, 2017 Those engines were such a good stock, reliable, money making motor. Be careful with it.....,with normal product improvement updates, you have one of the best stock engines Mack made. Good luck!!!🍀 Quote Link to comment https://www.bigmacktrucks.com/topic/51180-2000-cl-e7-427-upgrades/#findComment-381157 Share on other sites More sharing options...
2000CL713 Posted September 29, 2017 Author Share Posted September 29, 2017 Yea that's why I rather go with the 490hp program. Mack made it so it should be just as reliable then some modified aftermarket stuff.

880joe Posted September 30, 2017 Share Posted September 30, 2017 I ran the 75hp injectors from K+S for 4 years without any issues. About a month ago I put Rochester's stage 2.5 injectors in and new eups my driver said he about had to learn to drive it again it made a big difference. I'm driving a 355/380 with injectors from Antrim Diesel and 460 turbo I will loose 18 to 20 mph on the same hill my driver said he looses 2 mph Quote Link to comment https://www.bigmacktrucks.com/topic/51180-2000-cl-e7-427-upgrades/#findComment-381167 Share on other sites More sharing options...
2000CL713 Posted September 30, 2017 Author Share Posted September 30, 2017 (edited) All that gets very expensive lol hoping mackpro gets back to me with some good info lol What did those 2.5 injectors and eups cost you all together?

880joe Posted September 30, 2017 Share Posted September 30, 2017 I bought the new eup's off eBay for 200 each Rochester injectors will run you about 150 each K+S injectors are 85 a piece Quote Link to comment https://www.bigmacktrucks.com/topic/51180-2000-cl-e7-427-upgrades/#findComment-381215 Share on other sites More sharing options...
2000CL713 Posted September 30, 2017 Author Share Posted September 30, 2017 (edited) How much HP you think you where pushing with that setup? Also any reason why you went with the stage 2.5 over stage 3? Was there reason why you swapped all the eup? Did you need new ones or are they needed for the modified injectors?

MACKTRUCKS4 Posted October 1, 2017 Share Posted October 1, 2017 I have a 2000 Rd with a 400hp stock motor. Added super flow injectors (90 hp increase) and only changed the turbo to a 427 (which you already have) giving me around 490 with no other changes. Very few tri-axles around can run with it. My mileage is a lot lower, about 300,000. A friend has a 525 Cat and one day I was running with him and I out pulled him on a long hill. So either mine runs better or his runs weaker.

2000CL713 Posted October 1, 2017 Author Share Posted October 1, 2017 You have link to the injectors you used? Sounds like you have a good runner. What sort of mpg are you seeing?

880joe Posted October 1, 2017 Share Posted October 1, 2017 I changed the eup's because I had put some used 1's in in the past and never had the cal code done on them and some were leaking a little fuel also had 2 or 3 people tell me they got week over time mine probaly had a million plus miles. I belive I sent my old 100hp injectors from K&S to Rochester for cores and they compaired to there's and said 2.5 were just a little bigger and the stage 3s you would need to watch your egt's and water temp Quote Link to comment https://www.bigmacktrucks.com/topic/51180-2000-cl-e7-427-upgrades/#findComment-381290 Share on other sites More sharing options...
880joe Posted October 1, 2017 Share Posted October 1, 2017 I'm thinking 525 or 550hp probably need a little more turbo to cleen up the smoke and get a little more power Quote Link to comment https://www.bigmacktrucks.com/topic/51180-2000-cl-e7-427-upgrades/#findComment-381291 Share on other sites More sharing options...
2000CL713 Posted October 1, 2017 Author Share Posted October 1, 2017 I see. Stg3 wouldn't be for me then if I do go down that road. Living in FL my truck runs in hot weather 100% of the time. Don't want to do something that will make it worse. Would consider stg2.5 to be a reliable stg for my motor or would you have gone a diff route if you could do it all over again? My eups are orignal with about 600k on them. Quote Link to comment https://www.bigmacktrucks.com/topic/51180-2000-cl-e7-427-upgrades/#findComment-381294 Share on other sites More sharing options...
880joe Posted October 1, 2017 Share Posted October 1, 2017 I have not run the Rochester injectors long enough to know how reliable they are going to be. I ran the K&S 100hp injectors and did have a few of them split the tips. the Rochester 2.5 are supposed to be a little bigger but they claim they do their injectors different some how and don't have that issue guess time will tell. I never had any problems from the 75hp injectors from K&S they have been the most reliable ones and cheapest that I have used so far only been using Rochester for about a month now.

MACKTRUCKS4 Posted October 1, 2017 Share Posted October 1, 2017 http://www.reedysdiesel.com/ Never checked mpg. Sometimes you have sacrifice power for mpg. Where I run, it's nothing but hills and valleys. It did increase my egt's and water temps, but still in the safe range. Where you live it is for sure hotter but you don't have the hills to climb (except for overpasses, LOL) Quote Live every day like it's your last, because one of these days, it will be.
