Any feed back on Banks Power Pack for a 1994 Cummins B5.9L engine. Is it worth the expense?

goncolgo,

Welcome to the FMCA Forum.

Couple of questions:

Do you have the Allison 4 or 6 speed transmission. If the 6 speed, it CAN stand a HP boost. 4 speed, you would have to verify with Allison using your transmission model number.

Do you have the 190 or 230 HP Cummins B engine?

Do you know the weight of your loaded motorhome? Toad?

[goncolgo]

Thanks for your reply! I have a 190 hp engine with a 4 speed Allison tranny. I think the toad weighs in at around 18,000#, Oshkosh
chassis.

Then the first step is to give Allison a call tomorrow to see what the maximum HP/torque your transmission can handle.

Allison help line 800 252 5283

Thanks Brett for the info and advice. Wife and I just got this RV and are new to the life. Motorhome needs some TLC which we have both been hard at it. Its a Damon Challenger 34 foot and we are having problems getting chassis wiring info etc. since Damon is no longer. I just got RV and Maintenance Book by Bob Livingston and hope it will help troubleshooting some issues we have. Again, thanks for your reply. Kent

I sure hope you don't really mean your toad weighs 18,000 pounds!

I had a Banks PowerPack installed on my 2000 Itasca Horizon with a Cummins 275 ISB a couple of years ago. I can generally hold one gear higher when climbing a hill. Power spools up much quicker. Overall I am happy, but a bigger engine to start with would be better.

I had that basic coach and modified the engine for more power. Several things happened. I ran out of gears-- no overdrive. The engine overheated because the radiator is too small. The inter cooler is too small. I finally changed the engine to a ISB 275 with a MD 3060 6 speed Allison and the radiator and cac. Solved most of my problems.

goncolgo,

I did find this link that connects to other Damon web sights for parts and information.

I will see if I can find any leads to some wiring information. Oshkosh was bought out by Freightliner so they might have some chassis information.

Rich.

As Brett said the trans may be the first limiting factor, then the cooling system and intake next.

[goncolgo]

General consensus, bad idea, Allison even chimed in. Now a follow up, without the additional torque and HP do you think I could still tow a 3500# toad?

Oh, we are talking a Cummins B5.9L 190 HP pusher.

Merry Christmas to All

Thanks to all of you for your reply's!

I'm the one that said that.

It will tow but you won't be very fast in the mountains. Level road it will be just fine.
