Features & Benefits of Fummins Compounds:
Reasons Why Our Compound Turbos Work So Well:
Head Studs Recommended For:
Our Compound Turbo systems are all capable of over more than 55 psi, but are adjustable depending on truck.
EGT TEST RESULTS: The following test results were to test different single turbochargers against our Twin Turbo Kit (this test was on our HT3B twin kit which has less air flow than the S400 series kits). Each test consisted of a sustained 400hp dyno pull. The test truck was brought up to a 400hp on the dyno, and then loaded to hold a sustained loaded pull, equal to pulling a trailer up a grade using 400 hp. The EGT's were read pre-turbo. The results follow:
**While a downpipe is not included in this kit, we do include a machined exhaust adapter/reducer which v-band clamps onto the exhaust outlet of the S400 turbo, so that a 4” or 5” exhaust pipe can be welded onto it. We also do offer for $175 our 2nd Gen Dodge downpipe which is a close fit but may need slightly modified.
Our Fummins Compound Turbos, fit Ford Cummins conversions including Ford 6.0 conversion to Cummins, 60 to 12swap kit, Ford Super Duty Cummins Swap or a Ford Cummins Twin Turbos on Ford Gas engine to Cummins projects. Whether using a Ford 6.0 to Cummins conversion kit, a 6.4 to Cummins conversion, or any other Ford Cummins conversion. Our Fummins Twin kit will fit awesome, and run amazing.
Please note: Ford/Cummins, Chevy/Cummins or any other conversion kit are considered a custom application. The hardest part of these conversion kits are getting both turbos to fit in the truck and clear the heater core. Our compound kits are specifically designed to get both turbos to fit nicely. In most cases the intercooler hose will fit to a factory intercooler, and will allow the intake to fit as well, however because all of these conversion kits are so custom in nature it is the responsibility of the installer to tie in the intercooler, exhaust and intake tubing into the truck. This is because the engines, alternators, batteries, intercoolers, etc. can be done in some many different configurations it would be impossible for any single kit to universally fit every swap application. In most of the conversion applications, expect to do some fabricating to exhaust pipe, intake and/or intercooler tubing.
Thanks so much guys, fummins compounds fit like a glove. 97 f350 with 74k original miles , 6k on 24 valve Cummins & 47re swap ,shackle reversal , cross over steering and around 10 inch of lift .rolling on 37s .funny thing is I built this to pull our toy hauler. Can’t wait to pull with compounds. By the way I have to tell you I was skeptical of a fummins compound kit due to the lack of space but your guys on the phone assured me this kit would work. Wish I would have found you guys before I first installed my Cummins with a single BD turbo
This kit just fits! I went with the smaller 62/65 with s475 for my 2002 Excursion conversion. Best family tow vehicle. The kit fit and you told me I would have to modify the downpipe to fit and I just had a muffler shop do a custom fit downpipe and exhaust for me. We look forward to many more years of family camping with this new setup! Thanks DPS
