ekennedy21 Posted September 27, 2015 Share Posted September 27, 2015 What year did Mack come out with the e9 and what was the v8 prior to it? Quote Link to comment https://www.bigmacktrucks.com/topic/41971-e9-engine/ Share on other sites More sharing options...
AZB755V8 Posted September 27, 2015 Share Posted September 27, 2015 1978 the E9 was in prototype as the 1000 and 1005 and not intercooled. In 1979 the intercooled E9-400 went into production and ended in 1999 with the E9-500 in the USA. The engines pre E9 where the ENDT 865@325hp Maxidyne and ENDT 866@375hp Thermodyne. Both were not intercooled. Produced between 1970 and 1978. Quote Link to comment https://www.bigmacktrucks.com/topic/41971-e9-engine/#findComment-305332 Share on other sites More sharing options...

Dirtymilkman Posted September 28, 2015 Share Posted September 28, 2015 I'm pretty sure when I ordered my CL in 2000 I could've ordered it with the E9. But I wanted cruise.and didn't want an air throttle. Quote Link to comment https://www.bigmacktrucks.com/topic/41971-e9-engine/#findComment-305373 Share on other sites More sharing options...
Timmyb Posted September 28, 2015 Share Posted September 28, 2015 In Aus we got an electronic e9 in later years, hp ratings of 525, 575 and 610. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/41971-e9-engine/#findComment-305395 Share on other sites More sharing options...
ekennedy21 Posted September 28, 2015 Author Share Posted September 28, 2015 Did the e9 always have an air throttle? Quote Link to comment https://www.bigmacktrucks.com/topic/41971-e9-engine/#findComment-305399 Share on other sites More sharing options...
Dirtymilkman Posted September 28, 2015 Share Posted September 28, 2015 In Aus we got an electronic e9 in later years, hp ratings of 525, 575 and 610.A VMAC E9? Quote Link to comment https://www.bigmacktrucks.com/topic/41971-e9-engine/#findComment-305428 Share on other sites More sharing options...
bbigrig Posted September 28, 2015 Share Posted September 28, 2015 Yep. VMAC E9 was available in Aus. Long after it was killed in North America. The E9 I was told was killed off due to not meeting emissions. Never made sense though, as there was no new regs between 1998 and 2002??? The last year you could order an E9 was 99 so it could have been built in a 2000 truck. I believe that was when they started switching over to Cummins and deleting the Cat option as well.

AZB755V8 Posted September 28, 2015 Share Posted September 28, 2015 I believe the air throttle came out with the inline pump around 1990 or so. I don't think many guys liked it but it was suppose to saved a lot of broken drivetrain parts. Even with it the 94 CL I got for parts had clutch, trans (twice), drive shaft and front diff replaced by 400K miles. The E9 is still in great condition though. An E9 is a one driver engine not just give it to the new kid to learn on.... unless you want big broken parts. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/41971-e9-engine/#findComment-305450 Share on other sites More sharing options...
ekennedy21 Posted September 28, 2015 Author Share Posted September 28, 2015 is the air throttle reliable? seems like it could be a lot more finicky then a cable.

AZB755V8 Posted September 29, 2015 Share Posted September 29, 2015 Well for reliability?? Do you trust stopping every time you hit the air brakes? Same air and cylinder concept as brakes.It just seems a little mushy to me and lags compared to a cable. No real snap... Think there is a air restrictor to slow pressure build-up.If you have a diesel pick-up truck built in the last 10 years your pedal is not directly connected to the pump ether. I went to work on my kids car and the throttle is actuated with a motor and not connected to the pedal at all. There's a switch on the dash for "sport" mode that doubles the movement in the throttle motor.
