DIY TURBO 440-MOTORHOME GETS BOOST!

FULL BOOSTED RESULTS. TURBO 440 MOPAR. DIY TURBO KIT. Boost is what every low-compression, Motorhome 440 needs. We ran this test on pump to illustrate how well the 440 responded to boost from our single turbo. Using stock (cast) exhaust manifolds, I fabricated a kit that included a Y-pipe with dual Turbo Smart wate gates and a single VS Racing 7875 Gen 2 turbo. Big Torque!
