Cummins 315 HP In crease HP

[Pappie]

I have been trying to increase my HP in my 2000
diplomat, 40', Cummins tells me my nubers are one of the many that CAN NOT be increased in HP.
They said I would have to change all the pistons!!!
Got to be a better and cheaper way. I checked and can not find a computer chip that wii work on the 8.2 Cummins.
Any HELP??

Have you called Banks Power
http://bankspower.com/
Is that an 8.3 or an 8.2 dsl?

I would also give serious thought to calling these people and asking them about the UltraPower Upgrade. If doable, the cost might be about 1/3 that of the Banks System.

Suppose Cummins is right? As they increase horsepower & torque specs from time to time, they also beef up the engine components to handle it. It may be that your 2000 engine is indeed at its limits and needs beefier pistons, connecting rods or crank shaft to handle any additional load torque or horsepower. Risking a major engine failure to gain 5-10% more horsepower is a bad bet.

I don't know if Cummins is being ultra conservative or giving great advice, but I would be very cautious about ignoring them. Talk to Brazell and tell them what Cummins said about your particular engine.

Banks Power supplies all the items need to increase power safely with each application. If the motor is not deigned to take the increase in power then Banks will not do it. Installing Banks products will not void your warranty.

I have a "EZ 1000" on a 5.9L 275 hp and I am well satisfied!

With all due respect, one might want to take a look at the experience of Cummins/Dodge Ram users at dieseltruckresource.com or turbodieselregister.com before taking this statement to the bank.

Just my $.02 here.

We have a 1998 C8.3 and while yours is newer, I would bet that it is an ISC 8.3 or an 8.3L.

On our coach, the authorized Allison trans rebuilder in our area (So Cal) looked up the specs for our specific combo which is rated at 275HP/800FT# and said that while the engine might possibly be able to be increased to 350HP with a Banks kit or similar, the MD3060 trans was only good for a maximum of 800FT# of torque.

Allison also makes an MD3066 (which is only determined via the serial number) that is good for up to 1050FT#. I asked what might happen if I added the Banks Stinger kit which changes our numbers to 350HP/950FT#. I was told that it could be fine but they had seen similar setups and all had to have their transmissions replaced with rebuilt 3060's or upgraded to 3066's. The cost is right around $7,000.

I suppose it depends on how you watch the EGT (exhaust gas temperature) gauge/pyrometer but remember that the older ('96-00/01) 8.3 engines are I believe all 12 valvers while the 5.9 ISB's are usually 24 valvers. I am not sure the 12 valve engine can safely handle the excess HP. Later versions of this engine, possibly yours, have stronger internal components and were uprated by Cummins. The key is to call Cummins, give them your engine serial number and ask them what you might be able to get out of the engine re: HP. I would do the same with Allison and the trans.

It is all a guessing game as many others have modified their engine/trans combos. I don't happen to have the $1600 for the kit (nor the $750 for the installation and dyno tune at Banks) and while I can install and "tweak" the kit myself safely, I am ok with taking a bit longer to get to my destination.

After all, I/we are on vacation when in the coach.

Sorry so long winded but I have only found one comparable coach to ours that did the mods so far. His runs great BUT if I remember correctly, you do have to watch the pyrometer on long hill climbs with a toad.

I am not sure when the DW drives it that she will remember this critical factoid as she is busy driving.
