Pusher Low Mount Compound Turbo System for 1998.5 - 2002 Dodge Cummins 24v Trucks
Watch the Low Mount Compound System be assembled in under four minutes.
- This kit can safely support 750HP to over 1000HP depending on turbo and fueling configuration.
- Proven to increase fuel mileage 1-2 MPG during daily driving and 2-4 MPG during towing and highway use.
- Unsurpassed EGT control, reductions over 200F are common in mild applications.
1. Aren't compounds for race trucks?
No, absolutely not. A
properly size compound system can drastically improves every performance aspect
of your truck. A turbo charger has a fairly narrow efficiency range (a set of
operating conditions that yield a good amount of boost for the amount of
exhaust used). The stock charge is pretty efficient at the low-mid range of
power that the engine makes from the factory. Above that range, it requires
exponentially more power to spin. Thus by letting the atmospheric turbo in a
compound system do the top end work, the engine becomes much more efficient
which yields more power to the tires, lower EGT’s, better MPG’s, longer engine
life, etc.
2. How long should I expect the install to be? This setup installs extremely fast
for compound system. We generally recommend customers set aside a day to do the
install so they don’t rush it. Just for reference, we can install this setup in
about 6-8 hours working at a normal pace because we don’t need to read
instructions and are familiar with the process.
3. Do I need to buy anything additional to be able to install
this system? No, this is a turn-key setup that
only requires simple hand tools and knowledge. It comes with extensive
instructions so once you start the install, you should not have to go to the
hardware store, the auto parts store, etc. DISCLAIMER: if you have some sort of
“out side the box” mods done to your truck, it’s always a good idea to check
with us prior to purchasing this setup.
4. What size exhaust should I use? We’ve found that 4” works
quite well and keeps drone in check. That being said, the second turbo works
much like a muffler and significantly cuts down individual cylinder fire.
Generally all you can hear over anything more than a few PSI of boost with
compounds is….boost.
5. Is my factory turbo really going to work in this setup? Yes absolutely, the factory charger
is setup great for compound systems making up to about 700HP. It has a smaller
turbine housing which works great for low end spool time and a large internal
gate which works great for bypassing enough exhaust flow to the atmospheric
turbo.
6. Where is the waste gate? The waste gate is built into your
factory charger. It is critical to any compound system as it allows the primary
turbine wheel and housing to be small for good throttle response. It allows
this to happen by bypassing exhaust flow around the primary turbo in the
mid-top RPM range so the atmospheric turbo can do its job. If you’re
considering a compound system without a waste gate, don’t.
7. Do I need bigger injectors or any other increased fuel
delivery to run this system? That depends on how much
power you want to make, more specifically what you want the truck to do. This
system works great at 300-750HP. If you’re looking for a tow oriented setup
that makes great power and are looking for a 300-600HP truck, then we would
recommend a S471 with the stock charger. If you think you’re going to shoot for
500-700HP we’d recommend the S475 with the stock charger, swapping in a small
S300 based charger later can take the S475 to over 750HP. Lastly if you have a
highly modified stock charger and/or are planning to swap to mid sized S300
charger in the near future AND are concerned mostly with peak power, we would
recommend the S480.
8. Do I have to flip my stock exhaust manifold? Yes, flipping the stock exhaust
manifold creates the necessary room for the atmospheric turbo.
9. Do I need an aftermarket exhaust manifold? We have found that the factory
exhaust manifold works quite well with T3 chargers at around 700HP and less. If
you’re planning to make well over 700HP down the road, considering a manifold
and a primary configured with a T4 flange is probably a good idea.
10. Do I need to buy
anything additional to be able to install this system? No, this is a turn-key
setup that only requires simple hand tools and knowledge. It comes with
extensive instructions so once you start the install, you should not have to go
to the hardware store, the auto parts store, etc. DISCLAIMER: if you have some
sort of “out side the box” mods done to your truck, it’s always a good idea to
check with us prior to purchasing this setup.
