Bottom Line
High Performance Diesels
The King of Engines

The biggest, baddest on-highway truck engine ever produced has just been purchased by OOIDA member Frank Hieden of Houston, TX. Frank is now a member of the exclusive KTTA-HVT club that has only about five members in the U. S.

The Cummins KTTA-HVT is the King of Engines. The K, of course, is the mechanical K series 1,150 cubic inch engine; the TTA indicates that is equipped with twin turbos and after-cooler. Of course, hydraulic variable timing is HVT. The stock factory horsepower rating on this engine is 750.This engine at 750 hp, however, is only starting to release its potential. Pat Sharp, the fuel pump technician and Brian Moan, the injector specialist at Diesel Injection of Pittsburgh, have the combination of fuel settings to enable this beast of an engine to produce between 1,000 and 1,200 hp. As far as I know there are only five of these truck engines in use throughout the U.S.What in the world would you do with this much power? The heavy haulers of our country would greatly benefit from this engine. The people who spend a lot of time in the Rockies, Sierra Nevada, Grand Tetons (maybe hauling rock, gravel or any commodity 80,000 lbs. plus GVW) know what to do with it. This engine has the strongest bottom end of any engine ever produced, or in highway use. And, what a great engine this would be for the Australians to pull their trains!

This is a mechanical engine and there are only a few available. Please keep in mind, they quit building the mechanical engines in 1992. So, what's the price tag on one of these bad boys? The price of the mechanical KTTA-HVT is $44,000. If you don't have a KTA to trade in, the core charge is another $15,000. So raise your freight rates, order your special K and you too can be a member of the exclusive club of truly large-car owners carrying big sticks.

If you recall, in the past, I have written about Butch Shuman, another OOIDA member from Tye, TX. His re-worked 1978 A model Kenworth has this same engine and will break the tires loose at 84 mph using 52 lbs. of turbo boost pulling an empty bull rack. Now, Texas - the Land of Big - has two KTTA-HVT Cummins engines roaming the streets, and Frank and Butch happen to be very good friends. Frank Hieden's truck is also a Kenworth A model, which he purchased new was equipped with a KTA 600 single turbo Cummins engine. The 81 A model is equipped with a two-stick 6x4 transmission and 3:55 gears on 24.5 tall rubber. While Frank is replacing the engine, he's also installing new frame rails.

Now, on to the high performance diesel computer. In the last issue of Land Line we mentioned that the "Pittsburgh Power" computer would increase the total engine output horsepower by 140. For those of you who had questions, we have now increased the power to 175 hp at 25 hp increments. The dial on the LED readout, which will be mounted above your instrument panel, will have seven power levels. Each click of the dial will increase the horsepower by 25. Settings one through four, 25 to 100 hp, the LED readout will remain the same. Level five and six, 125 to 150 hp increase, will have a red light to keep you informed as to the power level. At level seven the LED number will blink to remind you that the horsepower has been increased by 175.

Please keep in mind this computer is for the N-14 Celect engines. We are working on the Celect plus and Cat 3406E engine as of this writing.
