Default What size injectors for blower setup?

I'm working on a roots blower setup for the TA and need to know what size injectors I should go with. Right now I'll be running around 5 or 6 lbs of boost on a stock internal motor but in the end I will be running 10+ lbs on a blower motor. Any ideas??

This going on a LT1? You dont see many roots blowers on LT1's. How dare you post this without details. I hate getting hard ons for nothing.

A cowl hood won't be necessary AND there is no cutting of the cowl area at all. Does that get yer interest up anymore??

Not much to tell really. I have no clue what kind of power it's gonna make, it's being putting on a stock internal motor for now with the lowest boost pulley there is, I'm assuming around 5 or 6 lbs, but eventually I'll build the motor for it. If there is enough interest I would entertain the thought of building a few kits but I gotta road test it and all that before I would consider doing that. I still have the intake ducting to build (hope to get that done tomorrow) then a few small details as in wiring extensions for the sensors, moving the water neck on top of the water pump out of the way etc etc but I hope to at least fire it up by the weekend. I'll try to get some video of it if I do and post that up. Stay tuned..........

Keep up the good work. I not a huge fan of roots blowers because of thier efficiancy but they do make decent power and gobbs of Tq. Cant wait to see the final product.

I dont see the big deal with the heat. Cobra and Lightnings dont have injector problems caused by heat from their Eaton when theyre maxing them out unported.
