Hubby says we need more power!!

Be careful with that one. According to the 2003 Neptune Brochure you have the Cummins ISB Low Torque engine rated at 275HP/600 lb/ft torque mated to an Allison MH2000 transmission.

Looking at the Allison Specs shows your transmission is rated for 300HP MAX with 780 lb/ft torque MAX.

HP wise you're close to the limit, and seeing as HP is a calculated number using torque and RPM, you really don't have a lot of room to play with that set up.

Bottom line - if you really want more power it might be time to start looking for a MH with a bigger engine and heavier transmission.

Am I helpful? :B :h

Are you helpful? Probably not, but, you are correct!

chuckftboy and olylin are giving good advice. These will make a difference, not break the bank, or anything else.
Good luck and let us know what is decided.

like I said if your serious get the banks kit they know what their doing they know what your Mh is capable of handling.I did a 350ISC and it was awesome

QUOTE: we want more power can someone suggest a upgrade

I see you just joined last month. You are going to have a heart attack on here if getting off subject bothers you. It has always been a problem and I suspect always will be.

You have to assume we are all sitting around a campfire and talking to each other. Lot's of things come up during those conversations.



How to make your signature so we can serve you better:

1. Log on and click "My Preferences".
2. On the "My Preferences" page click the middle box and enter your rig info.
3. Scroll to the bottom and click "Submit Changes"
4. Exit and you're done.

First thing I would do is don't listen to half on hear that just throw a lot of $$ at it and hope it will take the load. Then again if you have the xtra $$$ for a new trans and motor go for it, it's you $$$ and their advise. I would get a Scan Gauge D and see if your getting boost and temps are running low enough on climbs to add power, talking $150 and it plug and play. Then if you have enough trans add a bit of power 50HP and 50-100# of torque will make a difference and you will still have an arm and legs left to work with.

I can suggest an upgrade on power. Take the coach to an Oasis dealer and let them do a program upgrade. My son did just that 6 weeks ago for a cost of $400.00. His coach was 300hp and 650 torque and the software took it to 325hp and 750 torque.
Only Cummins can tell your husband how much power your rig can handle safely. My son said it made a big difference

FIgured out what you should do (JOKE ALERT)

You need to trade it in on a brand new 2018 BINFORD Motor home from Tim Taylor RV sales.....

(Ok, Running and hiding now.. Good night all)

upgrades have been suggested
but with the caution note
that it might not be advisable to do this, the tranny has too be able to handle the increased torque
