little puppy Posted January 17, 2018 Share Posted January 17, 2018 2011 MP8 1650trq. Eaton ultrasound 10spd I want to upgrade HP and bump trq. to 1850, local dealer submitted it to mack, they refused cuz of tranny, its not under warranty, I don't Care about tranny rating, I own it. Can any of you dealer guys tell me how to get around this issue? Do I have any options? I'll gladly sign a liability waver.

fjh Posted January 17, 2018 Share Posted January 17, 2018 Unfortunately they hold all the cards what you want don’t matter.thats the way it is.And it’s been that way for years even before the sweds got there hands on it! It’s not all a Volvo thing. Quote Link to comment https://www.bigmacktrucks.com/topic/52231-mp8-power-upgrade/#findComment-389830 Share on other sites More sharing options...

Maxidyne Posted January 17, 2018 Share Posted January 17, 2018 Any reputable truck dealer or manufacturer would give you the same response- They will not give you a power increase beyond what the truck's drivetrain was built for. They look at it from a liability point of view- If they turn up the engine and it grenades the transmission, they'll be liable for the damages.

little puppy Posted January 17, 2018 Author Share Posted January 17, 2018 I disagree, I've have a isx, and 2 c15's upgraded, I signed wavers for all, they wasn't under warranty. On both C15's. I upgraded the clutches for 2000 ftlb, eaton trans, are rated on the conservative side, of you drive it like you have a brain in your head your never break it. With a waver and no warranty, for them not to do it, is ridiculous on there part, 1 Quote Link to comment https://www.bigmacktrucks.com/topic/52231-mp8-power-upgrade/#findComment-389838 Share on other sites More sharing options...
Maxidyne Posted January 17, 2018 Share Posted January 17, 2018 What they're worried about is the next owner who abuses the truck, then blames the power upgrade when something blows.

HeavyGunner Posted January 17, 2018 Share Posted January 17, 2018 Kenworth turned up the Cummins I had in it above what he transmission was rated for no questions asked. They gave me he facts and said here's a waiver if you'd like the upgrade. Truck had lots of power mileage was a little better and nothing got destroyed because common sense was used. If you want to do something with your truck that you payed for and its not under warranty you should be able to in my opinion.

little puppy Posted January 17, 2018 Author Share Posted January 17, 2018 C15 18spd rated 1850trq. This load grossed 149,000lbs. When we had motor custom built for heavy haul, installed a 2250trq clutch, motor dynoed 670hp on the ground. I personal drove this truck 2yrs, never broke it.

Mackpro Posted January 17, 2018 Share Posted January 17, 2018 In cases where there is the small Fuller trans, we do the 505E download where you get the HP but not the torque. It helps. We havent ordered anything with a Fuller in a long time because of this issue. Jumping up to the higher torque Fuller is quite a bit more money when ordering new.

Mackpro Posted January 18, 2018 Share Posted January 18, 2018 On the MP engines , Mack charges the dealers any where from $200 to 1500 for the download then the dealers will usually mark them up a little. 95% of them seem to be in the $200 range ( dealer cost). The dealer submits a request form to Mack via E-service ( email type program) and Mack responds back with the available HP levels that engine can be raised to and cost to do it. We do about one a week. Quote Link to comment https://www.bigmacktrucks.com/topic/52231-mp8-power-upgrade/#findComment-389963 Share on other sites More sharing options...

GoldDog44 Posted February 10, 2018 Share Posted February 10, 2018 When I bought my truck it had a 445 MP8 with an mDrive and S38R rears. I wanted it bumped up to 505 and 1860. The dealer sent in the request and it was approved however the ECM in the 2014 CHU613 was to old for the 1860 so I ended up with 505 and 1760 which is still sufficient. No issues getting it done.

Pitchfork Posted January 24, 2021 Share Posted January 24, 2021 Any problems with the upgrade? I have a 2013 cxu613 with 445. Mack in Vineland nj approved the upgrade but I haven't done it yet. Other dealerships have advised to let it be. The difference isn't that noticeable and may open pandoras box to problems later. Any thoughts?
