Banks Power

I have a 2013 Itasca Meridian 34B; cummins 340 and I am thinking about having a Banks Power system installed. I am looking for more torque and pulling power for steep up-hills. I also pull a toad. I would like some opinions.

Ask Banks for the torque & hp curves with and without their mods. I don't see any Banks kit for the 6.7L engine after 2009, so there may not be much left for them to improve upon.

Yep, a lot of what Banks did is no longer allowed without recertification and it's too expensive for a relatively small outfit and return for Banks to do anymore. The Banks Power Pack on our 2002 DSDP w/ISC 350 really helped it but that kit is no longer made either.

The motor is tuned to the size of the transmission. If you have an Allison 2100, you are at the safe amount of torque. Too much torque could cause a lot of tranny problems

I bought this thing read'n about how every body had so much power with the diesels...

LOL. The diesel advantage is that it develops the torque at low RPMs, so you have the full horsepower on tap at low speeds and can accelerate well from a standing start. A gas engine has to wind up the RPMs to reach its rated hp. Other than that, 340 hp is 340 hp, whether made with diesel or gas.

The weight/horsepower ratio is the key factor for overall peppy performance. Most motorhomes are spec'ed at around 100 lb/hp and that ain't gonna be snappy. Your car is probably more like 20 lb/hp.

If you have one of the 2000 series Allison transmissions the torque is electronically limited to protect it. Find out what series the transmission is. If it's a 3000 series there is no imposed limit.

The Allison 3000 does, however, have a limit. Last I read it was 450 hp and 1250 lb-ft. More than enough for the ISB engine, though.

X2. That is correct.

Thank you for all of the information, I have to admit that I don't know much about horse power vs. torque, and I am still a little confused about whether or not I should pay the $4K to have it installed. My MH has an Allison 2500 MH transmission. Should I be concerned about overpowering the trans? Question: should I or shouldn't I move forward on this costly fix? I need more pulling power; especially going up hills. Thank you for all the help

Elycas,
I think you missed the point. Banks does not have any product to fix the 340 hp ISB. I have that engine also and have yet to find any add-on to give it more get up and go. I discussed the disappointing performance with a Cummins rep at last years Winnebago rally. All he could say was to take it to a Cummins shop and have them run a performance scan on it. I haven't done that yet.

Our new to us Magna is about 75 lbs per HP and it's very peppy for an almost 50,000# MH. Well, at least it was till the engine blew up. Cummins has a known problem with this engine doing exactly what happened to ours again.
