I have no idea I dont even know were the extra alternator sits. I am assuming next to each other? If it doesn't interfere with the bracket and procharger i would assume your good if not procharger definitely has the answers. But transmissions I am sure this would kill it in time. The transmission the 66rfe is a decent trans it uses some parts of the diesel version the 68rfe. But the diesel guys have had there issues with them so alot of extra power and one may find out just how much it can take. If it was me the transmission would be the first thing I worry about going boom.
I definitely would feel better about it with the ZF you have in your 2019 vs my 2018 66rfe. Hell one day when I get close to my warranty being over I may procharge mine especially when its paid off.
I meant to tell you transmissions are rated for torque not hp and believe it or not your transmission isn't the same as the hellcat. Yes it's a ZF transmission but yours is the 8HP75 not the hellcat 8HP90. The hellcat transmission is rated for way more torque raughly 737 lb-ft. You have to convert NM to FT LB. So yours the 8HP75 has 750 NM coverted to 553 lb-ft of torque which is still plenty. I will post a chart below of your trans highlighted. Now mine is a 2018 so I have the 66RFE. So converted the first number stands for the number of forward gears 6 and the second 6 means 600 lb-ft of torque and the rest is RFE Rear wheel Drive Fully Electronic. I am actually shocked the RFE has a slight edge on the ZF transmission in the torque department but not by much. If anything is going to break things when adding power it's going to be torque more so than horsepower.
oh yeah I see what you are saying. thanks for the chart. I know the Hellcat is not offered in AWD so I was bummed and stopped drooling over it so much and frankly I did not research its drive train but clearly I was wrong in the assumption that the ZF was only built with one model and used on multiple platforms.
At first I was thinking the ZF in the truck could handle a ton like the one in the hellcat not saying the ZF cant handle alot or isn't durable. I didn't realize it wasnt a 8HP90. But it makes sense they also use the 8HP90 in some Bentleys so I imagine its cost is crazy to put into every truck. I am sure ZF saves a ton of money by being able to switch the internals per whatever application they want to use it for. Still a ZF transmission is solid and very reliable from what I hear.
Yeah no doubt. But... could the drive lines and axles handle the 800 hp if 4wd was engaged?? What the heck is the Diesel guys using. Those trucks boast of 1000 lb numbers (not sure it it is torque at the crank or to the wheels)
When they are using the High Output cummins which is the one that is a 1,000 they now put in the Aisin transmission with 3500's. If it's a 2500 without the high output they still use the 68RFE. The Aisin transmission is a Japanese transmission that is a beast. The 68RFE is an in house transmission for Ram. The 66RFE I have uses some parts from its diesel counterpart. I believe you can only get the Aisin in the 3500 now with that cummins or may have always been that way. Gotta have a beast of a transmission to handle that torque.
You’re right. Aisin has always been in 3500. I walked away in 2013(may have been 2014) from a new Ram because the salesman told me the 2500 I was looking at had an Aisin. I always verify what they are saying and discovered that only the 3500/4500/5500 had them. That was too big of a mistake(benefit of the doubt but probably just lying) for me to give them business.
All about cost. I remember the Aisin used to be an option that obviously costed more and has the PTO function the 68RFE doesn't have. Probably saves them money still being able to put there in house transmission into the 2500 diesel instead of putting the Aisin into everything which is Japanese manufactured. The Aisin only is mated to the HO cummins not the regular cummins. But I agree its stupid keep one beast of a transmission for all of the diesels especially one that durable.
I finally read this link. It looks like I won’t be “tampering with the Emissions system” apparently I live in a stricter state then I realize. But the thread was fun anyways.
