Being the gluten's for punishment that we are, CPS has decided to test the old 'There's no replacement for displacement' adage on this 2011 Ram.
The truck is a 170K mile 2011 Cab and Chassis that we've used to develop our emissions equipped tuning. After reaching 505rwhp and putting the Aisin just about to its useful end we've decided to retire the 6.7L powerplant in favor of its big block counterpart.
Here she is before we initiate our shenanigans.
The Donor: A freightliner M2106 Businessclass will offer its heart for transplant.
The build will retain common rail fuel injection and hopefully a decent amount of driveability. Our goal is to build a very high horsepower truck that spools quickly and is somewhat more reliable than a very high horsepower ISB.
Facts about the 8.9L Cummins
1. It's heavier than the 6.7
~500lbs (per cummins)
2. It's 3 inches longer than the 6.7
3. It's taller and wider as well
4. Forged crank, big rods, and 2 piece monotherm style pistons (stock)
5. 540 cubic inches!
6. The control and fuel system isn't that much different than a 6.7
7. Needs an adapter plate unless using SAE #2 compatible trans
8. 14mm head bolts... stock
9. Wet sleeve engine, potential to go 47/8ths bore (640 cubic inch!)
First thing- Get our Freightliner running and see where it's at.
Guess we have a good reason to tear it down now... hah. .
More to come.
