This 3rd gen Cummins compound turbo kit is designed for maximum spool-up and great EGT control during towing, all while supporting up to 700 hp. This twin turbo kit uses your stock HE351 and an Aggressor S476. Many compound turbo systems usually employ a box S475 in their towing kits. While it does work, it is far from ideal. The turbine wheel in the S475 can support over 1,000 hp. It doesn’t make sense to suffer the lag of a 1,000-hp turbine if you are only after 700 hp. When compared to a typical compound kit with an S475, we typically see over a 100-degree EGT drop at the same power levels. The spool-up is, of course, much quicker.
The components in this compound turbo kit are all top-shelf items. The silicone boots we use are the best we've found. We have blown up many different brands of boots over the years, but we've never been able to blow up one of these! Our clamps are 13 mm clamps that have a torque spec that's 3 times higher than typical clamps. Basically, we have broken a lot of stuff over the years and have found the highest-quality components that will work for a long time.
Depending on what items you already have, you can custom option this kit to get only what you need. This kit uses a third-gen-style manifold.
