JBR injector air scoop

My question is has anyone ran a JBR carbon fiber injector hat on a roots blower with the airscoop? If so, how much did it pick up, boost wise? I'm sure Jeff knows the answer but didn't want to bother him with just one question. Thanks for the help, hopefully.

 

Whats an airscoop? you talking about that lip deflector? If so you can ask Pizza Joe I gave him one to run on his car, he said it picked up some

 

Yes Shawn, I wasn't sure what the exact name for it was. I've seen them on quite a few screw blower cars but not any roots and was curious. Thanks for the reply.

 

i use one and it picked up a little but mine was the earliest smaller one
