Stock Turbo over S475 (75mm-S400) Compound Turbo Kit



*With this kit you use your stock turbo as the small turbo.*

Diesel Power Source, Twin/Compound Turbo Kit, performs excellent when Racing, Towing, or Sled Pulling,but is very mild mannered.

SPOOL UP IS COMPARABLE TO STOCK, while raising airflow significantly. Customers are amazed at the spool up, and driveability. Again, SPOOL UP IS COMPARABLE TO STOCK. While most twin setups are sluggish off the line, this kit uses your stock turbo as the small turbo, allowing for very quick spool-up, which makes boost right off idle. Then a large volume S475 Turbo comes in to produce all of the airflow you'll need.

EGT's are typically reduced by 250-450 degrees, over a single turbocharger.Making towing with these Twins a dream. At 60 psi boost, drive pressure (exhaust) is appx. 70 psi, imagine how easily your engine is breathing, at nearly 1:1 ratio at 60 psi boost. Horsepower, and torque are increased throughout the entire RPM band, and significantly increased in mid and upper range.

Specifically tuned for 300 to 600 horsepower applications. This kit is the most unique and innovative Twin Turbo Kit available today, with features like: ••Direct bolt-on application, no cutting or fabrication needed. ••Uses only the stock oil return (no need to pop out freeze plug for the second return line), all oil returns in the single, stock block return line. ••Bolts directly up to the stock exhaust. ••The absolute largest air filter on the market. ••Air tubing is Silicone with Kevlar embedded, you don't have to fight to the a steel air lines. Tubing is flexible, and tested to over 100 psi. Tubes are sticky so they don't blow off, under pressure, and come in a variety of colors. ••Steel braided oil feed lines. ••S400 with 75mm Compressor Wheel on Secondary charger. ••3-Piece pulse manifold included in kit.

Head studs are highly recommended for boost pressure over 50 psi, and fire rings recommended for boost pressure over 60 psi.

This system is capable of over 60 psi, depending on truck, most trucks with a "Hot" chip, will see 55-65 psi boost.
