The HTB turbo series features strong, large shaft, extended
tip compressor turbos for aftercooled Dodge Cummins engines,
Available in 12cm or 14 cm turbine housings. With a 4"
exhaust system, free-flowing air box and fuel enough to
burn, 450-525 HP is the comfort range for this turbo.
The HTB line-up features extremely durable and responsive
chargers. Even after the initial quick spool-up, our 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
You have a choice of two different high-flow wastegated turbine
housing set-ups. You can get great spool-up. You can get drive
pressures down to 1:1 ratio at 45 lbs boost. These turbos
feature ported shroud compressor housings, well as dual ported
wastegates with adjustable actuators set by our shop at about
40 lbs psi. Keep in mind that boost equates to turbine speed
and once you exceed "safe" boost levels of a turbo,
any turbo will become a candidate for failure. Engine head
gaskets and other components are at risk as boost levels approach
High Tech Turbo HTB2/62
HTB2 turbos for 2003-2006 trucks are pretty much "bolt-up"
except for the exhaust downpipe. If you have been running
an HX40W then our outlet flange will make connecting to your
HX40 downpipe easy.
The 03-06 do not require a downpipe though an 03-early 04
might since the stock exhaust elbow necks down a bit.
For 3rd gen engines, we machine our turbo exhaust outlet to
accept your stock exhaust adapter so no downpipe is required.
A larger, freer flowing airbox (as well as 4" exhaust)
is a prerequisite for these high flow turbos. Be sure you
get enough air to these turbos by replacing the restrictive
air box on the 3rd gen trucks. *Some "high flow filters"
only flow 450 CFM. Please allow for 1000 CFM.*
A note about EGT's.
Customers who have done side-by-side comparisons of our turbos
have told us that their EGT's drop about 200 degrees using
our hybrid turbos as compared with their stock turbos. They
have also witnessed an additional 200 degree drop using our
HTB2.Whether we're talking about air flow or EGT's, you must
keep in mind that no two trucks are alike. Comments made here
are based upon specific dyno results as well as real world
experience derived since October 2003 from customers who have
tested these turbos for us in the field.Horsepower ratings
provided above are real-world figures at 1400 max EGT's at
5000 feet of elevation. Sure, we could claim 700-850HP based
upon certain dyno results using Nitrous and/or higher EGT's
but that isn't the world in which most of us drive.Be aware
that power makes heat. We've had many positive comments regarding
the lower EGT's these turbos provide. Drivers that used to
exceed 1500 degrees on a hard pull on level 1 of an adjustable
power box now rave that they can run level 5 before approaching
these same temps. But you WILL heat up as you add fuel. Please
be aware that fuel delivery and timing changes made possible
by the multitude of performance injectors, "chips"
or "boxes" out there will tend to over fuel any
engine and raise EGT's regardless of turbo or induction system
under various circumstances. The problem may not be the turbo
so much as it can be performance chip programming. Also, be
careful with your timing adjustments as these will kill of
a turbo quicker than fuel adjustments.
