    Secondary Port Injection Set-up (Not tuning related)

    6th gen camaro, about to put on Holley Low-Ram Intake, and i decided to go with the port injection rails as well so i could run secondary port injection, so i can actually have enough fuel system to support more boost, as well as more ethanol. For the controller i decided to go with the system that TooHighPSI sells, the Reflex+, as well as their Siemens 840cc injectors.

    Has anyone used the Holley Port Injection? If so, how did you plumb everything? As far as elbows, what size fittings, etc. Our plan is to get everything all setup except for the actual plumbing, and then running up to a local speed supply shop here in the city and getting what we need based on what we end up finding seeing. Just wanting some food for thought. I Also posted on Camaro6 but no one responded on there so i figured posting on here wouldn't hurt.

    Thank ya

    Keep in mind that the plumbing also depends on power level and fuel supply. If you have single or dual regulators double or triple pumps etc. Fore has a very nice diagram of the plumbing depending on your requirements.

    Those looking for more control options look at our kit: https://briantooleyracing.com/gen-v-...ction-kit.html

    There will also be another iteration of this coming out with the better ECU's (R3/R5) with even more options.

    Ive tuned 3 too high psi port injection kits. If you questions regarding plumbing I would contact Mike, they have those kits configuration down to a tee
