Revisiting our FPE roots, and feeling the Cummins was needing a little drop in replacement love, we've added another turbo to our lineup. Starting with an HE351cw (HE351ve in process, to be released at a later date), and tested on an EFI Live tuned 2007 6.7CR, sporting 120hp injectors, an FPE prototype stroker pump, and a stock 3rd gen manifold, plus all supporting mods to keep the head on LOL...
Initial testing with the same mods on the stock VGT turbo yielded 592/1208 RW on a Dynojet 224LC dyno. The test charger built off of an HE351cw found stock on 2005-2007 5.9s, and features an FPE custom billet 63mm Compressor and a high flow 65mm turbine wheel, as well as a larger internal wastegate. (21mm vs 24mm) Both the stock charger and Cheetah ran at a set 45psi of boost. The stock charger made 85 psi of drive at 45 psi of boost, while EGTs were 1900* @ 3000 RPM. The 63mm Cheetah made 45psi of boost and 55 psi of drive while only hitting 1550* @ 3000 RPM.
Final results showed nearly a 100 RWHP, 300 RWTQ gain over the stock VGT turbo, plus a significant drop in drive pressure and EGTs. Street mannersims are excellent, with great spool up, no annoying compressor surge, and outstanding top end power gains; all while still being a drop in replacement option on a stock or aftermarket T3 manifold. More dyno testing will be underway in the coming weeks on a heavily fueled 5.9. This charger is an option for near every model Cummins on the road today, and can be built to appear stock on all trucks from 1st gen to 4th gen.

PS. Ill get a dyno graph comparison up when I get a digital copy.
