So, I have been running my compound setup for 3 weeks now, and I am impressed on all levels. For 1500$, I have instant boost, 24 MPG, and even when I fuel it like a dragster, The highest EGT I can get is 1280*. Because of my awesome experience, I have decided to share the entire installation and give a few tips for anyone who wants to go this way. The kit I purchased is the Evilfab525 kit, here is the website link : http://www.evilfabperformance.com/shop

Are Cold Air Intakes Worth it? There has always been a big hype about getting a cold air intake. Well its been brought to my attention that cold air intake doesn't work as expected on turbocharged engines. My second in command on the forum ISX is a wizard of sorts when it comes to figuring out math formulas and calculating different things on the Cummins engine. From his research in this, there is such a small difference in volume that you'll never see a measurabl

A BHAF Muffler - Uhh?? I like the Cummins engine, but I try to do anything I can to make the engine quieter. The BHAF air filter flows lots of air, but it also allows a lot of engine air intake noise to be heard in the cab – more noise than the factory air box and the factory air filter. This inspired the idea to experiment with a BHAF muffler on a big honkin’ air filter – in this case, a NAPA 2790. A BHAF muffler is not for everybody. If you like air intake sounds, turbo

thanks to @TFaoro Here I'm going to try to go through everything I did to put an he351cw off of a 2005 CR Cummins onto my 2002 24valve Cummins. There may be some redundant pictures in here, so bear with me! I started by buying the parts I knew I would need. 2 turbo mounting studs from Cummins (I bought the stock length for an 05) These screwed into the bottom of the manifold. The other two were plenty long. 2 longer oil return tube mounting bolts 2 90d

This will show the progress in installing the Holset he351ve into my 2nd gen Cummins Second Gen Cummins should be considered 94-02 but there may be some difference depending on year. I will update as I go along. This is not dealing with the controller needed for the he351ve. The thread that covers the controller can be found here The Holset He351 ve vgt turbo was found on the Cummins 6.7 L trucks on late 3rd and 4th gen dodge trucks. It is a very tough turbo and was selected for

Turbo Inspection Operation Exhaust gas pressure (drive pressure) and energy drive the turbine, which in turn drives a centrifugal compressor that compresses the inlet air (boost pressure), and forces the air into the engine through the intercooler and plumbing. Since heat is a by-product of this compression, the air must pass through an intercooler to cool the incoming air and maintain power and efficiency. Increasing air flow to the engin

Description The intercooler system (Fig. 28) consists of the intercooler piping, intercooler and intake air grid heater. The intercooler is a heat exchanger that uses air flow from vehicle motion to dissipate heat from the intake air. As the turbocharger increases air pressure, the air temperature increases. Lowering the intake air temperature increases engine efficiency and power. Operation Int
