Turbochargers

   Selecting the best turbo for your application is a matter of choosing the right turbo for your intended power level and your intended application. While too much horsepower can easily push a turbo beyond its efficiency range, it is also important to consider your intended usage. Are you willing to sacrifice some EGT reduction for better spooling? Are you willing to give
up some bottom end for overall peak performance or sacrifice a little top end performance to maintain some bottom end spooling and towing performance? Can you afford the cost of twins to get both? There are tradeoffs associated with each turbo and exhaust housing combination. Choosing the right turbo and exhaust housing combination requires careful research and planning.

Selecting the best turbo for your application is only one part of managing EGT's. Effectively managing EGT's requires considering other components such as air intake and exhaust systems as well as camshafts and ported heads. In many cases just adding a larger turbo will not eliminate EGT problems. In most cases a larger turbo will lower peak EGT's and/or increase the length of time it takes to reach peak EGT's.

HX35

The  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.

The  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.

S300

The Super S300 is part of the Schwitzer S300 family. It is recommended as a replacement for the existing turbos on 1994 - 2002 Dodge RAM diesels. The Super S300 turbo is intended for moderately upgraded trucks that tow and/or for those running up to 400hp. Above 400hp you should consider the B1 Series or the PDR Twin Turbo systems.

Think HX40 air flow with HX35 spool up.

This is achieved by using Borg Warner's unique extended tip compressor wheel technology and low inertia, full-floating journal bearings. The result is a compressor that flows a decent amount of air, and yet has excellent spoolup. On the exhaust side, the Super S300 turbo comes with a dual volute wastegated exhaust housing. Like an HX40, the exhaust housing is a 4" outlet and requires the use of an HX40 downpipe and clamp.

HX40

 The HX40 turbo is designed for increased reliability and faster spool up, over a stock HX40 turbo. The HX40 turbo is recommended for trucks that are running between 350hp and 450hp. For trucks under 350hp you should consider the  HX35 turbo. For trucks over 450hp you should consider the  HX50 or Twin Turbo system. The HX40 is also a good choice for high 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 and racing applications should consider the  HX50 turbo or  Twin Turbo system.

Each  HX40 is custom made to our 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  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.

The Super PhatShaft series was designed for trucks that have multiple fueling upgrades used to tow large loads and trucks that frequent the track.  Super PhatShaft chargers are available in two size 62mm and 66mm  extended tip.  What makes the SuperPhat turbos special is the 71mm exducer exhaust wheel and modified exhaust housing.  We invested one year researching and developing the 71mm turbine to handle the aggressive fueling demands of our customers.  From this research the Super Phaft Shaft Series of turbochargers was born.  We were the first to develop the 71mm large exhaust wheel for our turbochargers and also set the standard for the rest of the turbo industry.  We found that the large exhaust wheel improves performance for 2 reasons, first; it lets the exhaust gasses expel from the charger more efficiently reducing cylinder backpressure and lowering EGT’s.  Second, it accelerates rotor speed to optimize compressor speed for more mid to top end performance required high performance. The wastegate has custom dual oversized passages and a wastegate spacer plate for maximum effiency.  Like all PhatShaft turbochargers it is equipped with dual grooved bearings and an adjustable boost elbow.                                      

 

 

Another first! The Silver Series PhatShaft is our latest effort to achieve perfection.  Much like the Super PhatShaft it was designed to handle multiple fueling upgrades and comes in three sizes 62mm 64mm, and 66mm.  What separates the Silver PhatShaft from the SuperPhat Shaft is our new technology 74mm turbine wheel.  To improve on the Super PhatShaft turbos we needed improve performance at a lower rpm range and we needed to reduce compressor surge.  We came up with is the 74mm turbine which is the latest in turbine trim design technology.  The new trim design transfers exhaust gas energy more efficiently than any other turbine on the market. It also allows for better exhaust gas expulsion which results in lower EGt’s and quicker rotor acceleration.  The most important benefit of the 74 mm turbine wheel is that it gets rid of turbo surge and broadens the power band range.  Another identifying characteristic of the Silver series PhatShaft is the polished compressor housing.  The Silver series utilizes the proven 14cm exhaust housing in which we modify the angle of the exhaust nozzle. We also maximize the wastegate ports and enlarge the wastegate chamber for full wastegate travel.  Like all PhatShaft turbochargers they are equipped with dual grooved high performance bearings and an adjustable boost elbow.  Our Sliver chargers have been proven to support up to 800hp and are the best turbochargers on the market today. 

The Compound PhatShaft turbos for the Cummins 5.9L are offered in two different kits, Towing and Racing.  Compound PhatShaft towing turbos are built with a PhatShaft 62 as the primary charger with the K31 as the secondary charger. Both the primary and secondary turbo’s on the towing Compounds are wastegated for ultimate control of boost and back pressure.  This unique combination offers quick spool up and unmatched towing capabilities. The Compound PhatShaft racing turbos are built with a Silver Bullet as the primary turbocharger and a modified Big Brother as the secondary charger.  The racing compouns are a perfectly matched set of turbo's for over 800HP

HTB turbo series features strong, large shaft turbine wheels along with extended tip compressor wheels for intercooled Dodge Cummins engines. 

With a 4" exhaust system, free-flowing air box and fuel enough to burn, 325-625 HP is the comfort range for these turbos. Since the introduction of the HTB2 turbo in July 2003,the HTB line-up has featured extremely durable and responsive chargers. Even after the initial quick spool-up, HTB turbos build boost even quicker than other hybrid turbos so that there is plenty of boost at low-end, for towing and, well, for sheer fun. The result is minimal smoke as well as even lower Exhaust Gas Temperatures (EGT's).

They offer 4 compressor choices culminating in the 66mm inducer of Sled Puller. The turbine wheel has a 65mm exducer. You have the choice of 2 different high-flow wastegated turbine housing set-ups as well. You can get great spool-up, as well as drive pressures down to 1:1 ratio at 45 lbs boost.

*A note about compressor choices -The 57 and 62 compressors are the best choice for all around streetability / towing.
The 64 and 66 compressors are primarily competition compressors. Approximately 10% of our customers have witnessed excessive "surging" issues  at lower RPMs (below 2000) and higher boost (above 20 PSI) conditions when using competition compressors for towing or daily driving.

All turbos are covered by a 1-Year factory warranty

Twins

The  Twin Turbo system is recommended for trucks that are running over 450hp in high performance street, racing and pulling applications. Our system is ideal for high horsepower trucks that tow and high horsepower applications concerned with minimizing turbo lag. Or if you simply want your truck to have it all. For trucks under 450hp you should consider the  HX35 and HX40 turbos. For higher horsepower trucks that do little towing and don't need to spend the costs of a twin turbo setup, consider the HX50 turbo.

The  Twin Turbo system consists of a HX40 with 16cm housing for the primary and PDR HT3B turbo with a 26cm housing for the secondary turbo. Both turbos are custom built to specifications, including modifications to the oiling of the turbo shaft,  extreme heavy duty bearings, and zero balancing.

The Twin Turbo system starts with a  HX40 with a 16cm exhaust housing. This allows our system to provide the optimum balance of quick spooling for street and towing needs, yet allows the system to breathe enough for the large volume of air flow that 65+ psi of boost can produce. Our modified 16cm exhaust housing is designed so the wastegate works on all 6 cylinders. This prevents over speeding of the primary turbo and maintains proper drive pressures. The wastegate is adjustable from 50 to 65 psi.   HRD recommends no more than 45 to 50 psi without O-Ringing the head. With various combinations of O-Ring'd heads, special head gaskets and our complete  intercooler boot kit up to 70 psi is can be achieved.

The Twin Turbo kit comes with a 5" downpipe that is long enough to run just past the transmission bell housing area. It is the customers responsibility to complete the exhaust system from here. We recommend a complete 5" exhaust for all high hp / high boost applications. For those needing an exhaust brake, the kit can be combined with a 5" remote mount exhaust brake from PacBrake ( not included ).

The  Twin Turbo system uses large aFe air filter with 5" inlet. The intake curves up and around sitting in the same location as the the stock airbox. Because of the 5" inlet, existing air intake systems such as an aFe Mega Cannon or Scotty2 will need to be replaced with the aFe filter that comes with our kit.

The  Twin Turbo system allows the customer to keep the second battery. For trucks equipped with automatic transmissions, the heat exchanger down by the transmission bell housing will need to be removed. This will require the use of an aftermarket transmission cooler to keep tranny temps in line while towing with heavy loads. This is not included in the kit.

The  Twin Turbo kit can be sold as a complete kit including both turbos and exhaust housings, all plumbing, air intake system, oil return lines, clamps and mounting hardware.

The  Twin Turbo kit can be sold as an upgrade for those who already have a HX40/16 turbo and ATS manifold. The existing 16cm exhaust housing will need to be exchanged for the one that comes with the twin turbo kit.
