Alright... School Me On Turbo's...
Ben and I have been sitting here on the couch debating what turbo I should run on the truck... That's right... The goofy SOB has been here all weekend drinking my beer and eating my food. While it is months away, I would like to have it by June for the Dyno Day but there is ALOT of crap around the house here that needs to get done before I drop more $$$ on the truck. I like to set goals though. The truck is more of a Street terror then a track truck. Steph has been driving it to work everyday and would like to continue to do so. I also want to be able to toss 10,000lbs behind it and not worry about lag or it being a dog so stock or better spool up is a MUST. Not looking for all out power just something better then stock. And also don't just toss up numbers... Explain to me what they mean and how they effect the truck.
Thanks!

Welcome to Turbo School
When in the process of bombing a CTD you will have to increase your fuel. With the increase of fuel comes an increase in heat. You can safely run 1200° once in a while but major failure can occur if your running at high heat conditions for a period of time. To keep things cooled down and to accommodate the added fuel You will need to Upgrade your Charger. There are Many Options and each have there own benefits and are designed for specific applications some are single charger set ups while others are twin charger systems.

The PDR HX35 is a hybrid or modified HX35 turbo. It is recommended as a replacement for the existing turbos on 1994 - 2002 Dodge RAM diesels. The PDR turbo is intended for stock trucks that tow and/or for those running up to 350hp. Above 350hp you should consider the PDR HX40, B1 Series or PDR Twin Turbo systems.
The PDR HX35 takes the stock turbo and installs a bigger pinwheel on the compressor side, then machines each housing to very close tolerances that match each individual pinwheel. The result is a turbo that spools up faster than the stock unit and stays within its efficiency range much further. Since we are modifying the compressor side of the turbo, our turbo works the existing 12cm, 14cm, or 16cm exhaust housings and exhaust down pipes. There is no need to buy additional housings or exhaust systems for many applications. This also allows our turbo to retain the use of exhaust brakes as well. For trucks with higher horsepower, we do recommend a 14cm wastegated housing and a 4" exhaust system.
Be sure to specify what year truck you are ordering for. On 1994 -1998.5 Dodge RAM trucks the wastegate actuator bolts to the exhaust housing, and on 1999 and newer trucks the wastegate actuator is bolted to the compressor housing. We have a design for each.
The PDR HX35 can be used with 2001-2002 automatics with HY35 turbos. A complete turbo with a 12cm to 16cm exhaust housing is required. The turbo will not fit a 9cm housing.
The PDR HX35 can also be used with older 1989-1993 Dodge RAM trucks with WH1 turbos.
The improved air flow from our modified turbo has many benefits. The decreased spool up time improves low end throttle response, reduces turbo lag, reduces smoke at low end acceleration, up to 100 degree reduction in EGT's, and quicker turbo cooling at shutdown.
The PDR HX40 turbo is designed for increased reliability and faster spool up, over a stock HX40 turbo. The PDR HX40 turbo is recommended for trucks that are running between 350hp and 450hp. For trucks under 350hp you should consider the PDR HX35 turbo. For trucks over 450hp you should consider the B1 Series or PDR Twin Turbo systems. The PDR HX40 is also a good choice for medium horsepower trucks that do a lot of towing, and for customers who would prefer less turbo lag and more streetable driving manners versus customers looking for all out performance. Trucks intended for high performance street applications should consider the B1 Series turbo or PDR Twin Turbo systems.
Each PDR HX40 is custom made to PDR specifications, including modifications to the oiling of the turbo shaft. These modifications along with zero balancing have lead to a significant increase in reliability.
The PDR HX40 comes with your choice of either a 16cm or 18cm housing. Both housings are specially modified for faster turbo spool up. Our proprietary modifications allow a 16cm housing to spool like a 14cm housing, while still maintaining the top end airflow of a 16cm housing. Our 18cm housing spools like a 16cm housing, while maintaining the top end airflow of a 18cm housing. For most applications we recommend the 16cm housing. For heavily fueled and racing applications the 18cm housing is preferred.
With HX40 exhaust housings, the flange is 4" straight out of the turbo and does not use an exhaust elbow. For most applications, this will require the use of a new down pipe. Our kit comes complete with a new down pipe and all gaskets necessary for installation.
Typical turbo mount exhaust brakes are not compatible with HX40 exhaust housings and down pipes. The use of an exhaust brake with a HX40 turbo requires a brake that mounts downstream in the exhaust, such as a 4" remote mount exhaust brake.
Fits 1989 - 2002 Dodge RAM Cummins Turbo Diesels.
The B1 Bomber Series turbos are a complete line of turbos intended for medium to high horsepower trucks, who want to stay with the single turbo design. Low to medium horsepower trucks should consider the more economical PDR HX35 and PDR HX40 turbos. For the extreme horsepower trucks, you should consider the PDR Twin Turbo system.
The B1 turbo line is renowned for its toughness, and its ability to move a large amount of air for the compressor size. The B1 line is built from quality Schwitzer components using a large shaft diameter, at least 1mm larger than an HX40. The hub area extends out further, lending greater support to the turbine blades and the blades are zero balanced. The B1 hub also features a second oil groove on the hub, whose purpose is to sling oil and keep the bearing cooler. The B1 turbocharger bearings are of a much heavier build which allows better cushioning for the vibration of the shaft as it spins at high RPM.
B1 turbos are available in the following turbine configurations. All B1 turbos utilize the same compressor wheel ( except B2 and Big Bother ). Different exhaust wheels and exhaust housings are used for the different configurations.
B-1 Bomber Mid to high hp std transmission
B-1-2 Mid to high hp, faster spoolup than B-1
B-1-EX3 Same as B-1 with HX35 outlet
B-1-EX4 Same as B-1 with HX40 outlet, can use the HX40 down pipe
KSB-1 Bomber Mid to high hp with faster spoolup than B-1-2
KSB-1-2 Very fast spoolup, high altitude, automatic transmission
KSB-1-2-03 2003 bolt in turbo upgrade
B-1-2-tow Recommended for the tow vehicle with manual transmission
KSB-1-2-tow Recommended for towing with an automatic
B-2 Turbo Used as lower turbo in twin application 600-700 hp
Big Brother Used as lower turbo in twin application 800-900 hp
