rsb502 Posted September 9, 2013 Share Posted September 9, 2013 uh, well the E9 is a 16.4 liter V8 the E7 is a 12.8 liter 6 cylinder, the E9 has a lot more torque and the mileage is actually about the same since the E9 isnt really working hard, at least it has been for me , got 6.8mpg with an E7 400 and 6.8mpg with an E9 440 that made more like 600hp. 2 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/32706-e7-400-and-e9-400/#findComment-205001 Share on other sites More sharing options...

ws721 Posted September 9, 2013 Share Posted September 9, 2013 I'm averaging @ 6.1 mpg with my E9. And that's pulling dropdeck, log trailer here in New England. A big cube engine wont have to work as hard. 2 Quote Remember if it's got a hood it's no good!

Mack Doctor Jr. Posted September 10, 2013 Share Posted September 10, 2013 I have never pulled a load with my E9 yet. I have been told if u keep ur foot out of it and dont show off with the smoke, the E9 is way better. I have drove tons of pumped up E6 350 and they will eat fuel on windy days. Im sure the E9 dosent even notice the wind blowing. lol Quote Link to comment https://www.bigmacktrucks.com/topic/32706-e7-400-and-e9-400/#findComment-205086 Share on other sites More sharing options...
e9500v8 Posted September 10, 2013 Share Posted September 10, 2013 You will throw rocks at the E7 after you pull a load with the E9 !!! Quote Link to comment https://www.bigmacktrucks.com/topic/32706-e7-400-and-e9-400/#findComment-205172 Share on other sites More sharing options...
Popular Post mack mhe9 Posted September 10, 2013 Popular Post Share Posted September 10, 2013 Driving an E9's like owning a weapon you have to be responsible. If your out to race everyone or show off there will be a price to pay. But if you let it do its job it will last a long time. 5 Quote Link to comment https://www.bigmacktrucks.com/topic/32706-e7-400-and-e9-400/#findComment-205186 Share on other sites More sharing options...
rsb502 Posted September 10, 2013 Share Posted September 10, 2013 an E9 could be a weapon of mass embarrassment to Paccars! lol 2 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/32706-e7-400-and-e9-400/#findComment-205258 Share on other sites More sharing options...
BAD DOG Posted September 11, 2013 Share Posted September 11, 2013 Yeah I agree I you treat an E9 with resect it will is very efficient and will last you a long time. As for parts if you have patience to look you can find anything you need or with modern technology someone can make anything you can't get from Volvo. By far the best engine Mack made. The guy from NY told me at MATS that I had a far superior setup with my E9 with the Robert Bosch injection Mack E9 to any Cat. And there are alot of good pulling Cats everywhere. I've pulled up the Niagra Escarpment grossing close to 140,000lbs with my E9 450 And the only thing I know that is done to it is the fuel plate is slid up as far as it will go and a slight adjustment on the screw on the aneroid valve, and I have climbed it a good 10mph faster than 600 Cats. And I got as good of mileage as any of them. As far as cost of fixing try working on any of these new engines. I drive a 560 ISX Cummins in. W900L KW and every hill I climb I wish I had my E9 plus the Cummins is always in the shop costing big $ to fix. Give me a n E9 any day. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/32706-e7-400-and-e9-400/#findComment-205284 Share on other sites More sharing options...

Jamkar Posted September 11, 2013 Share Posted September 11, 2013 G'day all, I don't think anyone really answered the question, is one 400hp engine better or more thirsty than the other 400hp engine?

rsb502 Posted September 12, 2013 Share Posted September 12, 2013 ok ok sorry my stupid fingers got the better of me, an E9 450, im sure im making over 540 right now but well go for the Mack paperwork to go in the brochure. Bad Dog, if you have a chance go get it copied at a local copy shop that can make it look good and mail it to me, Ill send you a check or paypal or something for it.

Lmackattack Posted September 13, 2013 Share Posted September 13, 2013 What was the better pump..... the inline pump or the "V" ? Quote Link to comment https://www.bigmacktrucks.com/topic/32706-e7-400-and-e9-400/#findComment-205795 Share on other sites More sharing options...
Mack Doctor Jr. Posted September 13, 2013 Share Posted September 13, 2013 Inline for the most part. Some beg to differ. Inline was easier to put barrels in and the V pump leaked if u changed the barrels and cranked it to hard.
