Now keep in mind, that is a engine dyno with nothing driven off of the crank pulley. They also used a stand alone Fast pcm's witch is much better tuning. Adding in drive train and accessory drag (a/c, alternator, power steering, water pump, tc, trans, rear axle, brake drag, ect...) and that will drop the hp/tq quit a bit. Minimum loss of 100 to 200hp/tq especially if you have a 4x4. There will be hp/tq loss just by using the oem pcm. A good rule of thumb is 18 to 20hp/tq (per pound of boost) gained by adding boost to a stock 5.7 Hemi engine. 20 to 22hp/tq per pound of boost to a built turbo 5.7 Hemi engine. Even more hp/tq per pound of boost on a stroker built engine.

WARNING: Boost is addicting... Once you've gone boosted, you'll never want to go back. :D

Has anyone noticed that these high powered, high boosted (18-22psi+ boost), twin turbocharged Hemi's have been running the stock oem plastic intake manifold with a stand alone pcm? One of them even with the small port plastic car intake manifold. Also a twin turbocharged 9 second truck with shorty headers. Take a look at Richard Holdener vids using long tube vs short tube headers with a turbo. See anything interesting?

In this video these guys did what I am trying to do with the Thottle Body!! (drive by cable) I am not sure, but I think they may be using a stand alone Computer :ermm:
