Monster-Ram 6.7L Power Difference
Gale Banks Commented:
I can tell you this, when we hot rodded the first 5.9L common rail back in 2001, the Cummins guys sent us a lab engine that they had put an HX-40 Holset on and some bigger injectors. The engine made 402 hp. We dyno'ed it again on our end and got 405 hp so our dynos matched. We sawed off the stock manifold, made the first ever side draft intake casting, cleaned up the ports and picked up 135 hp at the same air/fuel ratio with the same turbo, 540 hp was the result. So there's a dyno comparison doing the same thing as the improved horn, only better. We then installed a Banks cam and a larger VG turbo and brought it to 735 hp, put it in a Dakota, towed our trailer to Bonneville with it dropped the trailer and ran 222 mph!
