The
Aurora Turbo System is a first in the industry for true performance
gains while maintaining low EGT's and are designed using the most
efficient compressor wheels available. All ATS Aurora turbo chargers
utilize the most advanced compressor wheel designs offering high levels
of boost pressure wile maintaining low compressor discharge temperatures,
this allows for a larger density of air to enter the engine providing
huge power gains. All of the Aurora turbo kits come standard with
a 4-inch exhaust discharge pipe, unlike other aftermarket turbo kits
on the market using only a 3.5-inch down pipe, the Aurora 4-inch down
pipe allows the turbine to exhaust all of the exhaust necessary to
relieve the restrictive back pressure. When looking for extreme performance
with unsurpassed reliability, the Aurora turbo kit is the only choice.
ATS offers a wide variety of different Turbo Charger kits for the
Duramax LB7, LLY and LBZ Engines.
Up-grade Packages for the Duramax 6.6L Diesel for special
applications such as heavy towing or extreme performance race
applications. ATS offers two frame sizes in the Aurora Turbo
family.
Aurora 5000 Turbo
For maximum power and boost, there is just no substitute for The
Aurora 5000 Turbo. The Aurora 5000 utilizes a five inch compressor
intake and is capable of boost levels of over 60 PSI. This is the
only single turbo production kit available that is capable of producing
power levels of over 700 HP on diesel fuel alone while still allowing
street manners. The Aurora 5000 turbo is not intended for heavy
towing applications, due to it's very large compressor any towing
should be done in lower gears such as 4th.
All Duramax
applications are available from 2001 to 2006, the 2004.5 and later
LLY and LBZ GM Duramax engine were produced with a Garret variable
turbo charger that has proven to be a very sluggish inefficient
"emissions regulated" turbo charger. The later variable
geometry turbo charger suffers mainly due to its poor turbine design.
As exhaust is pushed from the engine to the turbo chargers turbine
housing the exhaust energy is forced to make a 90 degree angle being
directed into the turbine of the turbo charger. This violent 90
Degree redirection of exhaust causes a pressure wave to form in
the accelerating exhaust gas exiting the engine creating dangerous
unwanted back pressure. The high back pressure creates high exhaust
gas temperatures, The stock variable Garett turbo design causes
approximately 200 Degrees higher exhaust gas temperatures over a
conventional turbine housing due to it's inefficient turbine design.
The poor factory turbo charger design is the primary reason the
2004.5 and newer Duramax engine struggles producing reliable power
wile maintaining reasonable EGTs. The ATS Aurora Turbo system corrects
all of these problems and delivers unbelievable performance.
NOTE: Head Studs are recommended whenever generating
boost levels of over 45 PSI.
