All,

What would it require to bump a 330 ISC to 350 HP? Any negatives to doing it?

Any idea of approx. cost?

What the heck- you can bump it to 400HP. The negative is it'll set you back $250K+. Seriously, I'd check with a Cummins dealer.

You're looking at about a 5.6% increase in HP.

You would never notice the difference.

IMHO, the cost/benefit would not be worth it.

Banks is popular for ISC upgrades. I think they have multiple packages, one with an advertised 119HP/284Tq bump.

I had a 330 in 1999 (2000 model year). I inquired for the same HP increase. Cummins checked my motor ID and told me that on my engine, it would require a piston change. Apparently, there was a 330 engine built that required only a chip (+ something) to make the increase. Mine was not that simple.

Bob, Jim & Mary Jo have the answer. Banks is the way to go and they are a high class outfit.

Cummins can take care of the additional 20 hp by reprogramming your ECM

Thanks all.

After 3,000 miles averaging 9 MPG by miles driven/gallons used and not having any real trouble with hills, I think I'll leave well enough alone.

Bob and Peg,

The only time I want more HP and torque is when I'm running with the new coaches with the ISL.

Hi Tom,

I don't know as I want to run with the new Coaches. Mine is fully de-bugged and I don't want to take the risk of catching anything

You have chosen wisely, Grasshopper.

Once upon a time, when I owned a '94 250HP mechanical Cummins, I asked a Cummins shop manager (in Biloxi) about adding a Dr. Performance Kit to my engine; was to up the HP by about 50+, and he simply asked me "What do you want it to do that it doesn't do now?"
That's a helluva good question. He went on to say, "yeah, you can boost it up at the expense of seeing it start to fall apart in half the usual time.

I decided, like the 9 MPG, to leave it alone.
