I recently finished up a bunch of dyno work at Westech Performance using my GMPP 350 crate engine, including one of the coolest products I've used in a long time.
You're gonna have to wait for the first story installment in the March '10 issue of Jp for the full skinny, but until then, check out the new Powerjection III system from Professional Products, http://www.professional-products.com.
Looks like a carb, doesn't it? It 'aint. It's one of the slickest fuel-injection systems we've come across in a long time. And we think it's a natural for the off-road market. Installation couldn't be easier. You just bolt in on like a carb, hook up the throttle linkage like a carb, and plumb in the included high-pressure fuel pump and filter to the injection's fuel inlet and return ports. The adjustable fuel pressure regulator comes pre-set at the requisite 45psi, which you can verify with the built-in fuel pressure gauge. And check the boost-referenced vacuum fitting in case you wanna plug and play a supercharger or turbo charger.
Yeah, we know what you're thinking - what about tuning it and wiring in the nightmare of electrical connections, worrying about converting to an electronic distributor, and so on. Sorry, not needed.
The wiring harness technically only requires 3 wires to make the system run. There's a positive to battery, a key-on positive, and a connnection to your tach signal (coil signal). Of course, you'll want to hook up the included O2 sensor (no welding required) so the unit can operate in closed loop and the coolant sesnsor so it can adjust for cold-engine drivability. Make your electrical connections, hook up your laptop, and answer a couple questions like how many cylinders your engine has and how much torque it makes. Then unhook the laptop, fire the engine, and drive it.
That's it. You just added fuel-injection to any engine ever. The Powerjection III comes with 4 62lb-hr injectors, so if you're installing it on a 4-cylinder or smaller V-6 you may want to step down the injector size. But the point is, for less than half the cost of most complicated injection systems on the market you can have an easily-installed injection system that requires no tuning, no complicated installation, no special manifold (mounts to any square bore 4bbl manifold), and makes more power than a dedicated dyno carburetor.
The March '10 issue will include a full overview of the Powerjection III and what kind of power it can deliver with a street-oriented dual-plane intake as well as a swoopy Professional Products single-plane. We'll also cover how the system sets up, learns by itself, or can be manipulated for custom tuning if required to compensate for bad cylinders, poor intake flow, or for any other reason you could dream up. Then, the following month we'll cover the full installation in our '68 M-715 and head out on the road and into the mountains for a full on-and off-road driving evaluation. Tune in 'cause at this is one slick fuel-injection system that offers the power of MPI with greater ease than TBI. It's truly a genius invention we're stoked to share with you.
