Powerjection I

Does anyone here have any experience with the Powerjection I TBI? I posted this question in the Carb discussion board previously, by mistake and it got closed rather than moved here.

Re: Powerjection I

It looks like its basically a 4 barrel TBI with 4 injectors inside the faux metering blocks. This is similar to the accel system. It also looks like its kinda pricey. $1800-$2200. Thats a decent chunk of change for a system that essentially works the same as the stock TBI system since its still wetflow. It's probably better to just get a larger TBI. Even a new 2" 670 CFM TBI can be had for around $450 from holley and is enough to feed most street setups.
