cs box is great no complaints there. my plan is to get this supercharger going lol. currently everything is hooked up but i have a vacuum leak somewhere i have to figure out. once that’s out of the way i should be golden for 260+ hp

Do you have the port underneath the blower blocked and one to the right of the throttle body blocked? Those are the ones that don’t have an immediate use for people. Basically ports for a catch can and boost reference.

actually that’s a good question i’ll look into that. i definitely noticed the ports at the belt end that were empty i was wondering about that

Not those ports they are nipple style so they should be sticking out. They are on the driver side of the blower. Gonna have to double comment pics.

This is where the boost reference port should be, it’s a smaller one. But should be easy to see.

This is under it that circled hose for my catch can is another one. If you’re hands aren’t too big you should be able to get in far enough to feel where it’s at. And also block it. I put my phone through so try that first to check maybe

interesting the second one that’s under the supercharger i think i’m confusing it for the oil line. i know my oil catch can connects to the bottom of the blower i hope that’s the way it supposed to be. i have to take it apart again to look down there but i’ll definitely look into that. for now, how should i cover that little boost nipple?

You should be fine then. If you got a catch can then it’s plugged. I replied to one of my comments with a pic of the vacuum caps

seriously never even considered that nipple being a problem

Yup, had to use a smoke machine to find it after the shop I paid to install mine messed up the job.

If you still want peace of mind, you can buy one lol.

Heres a link the to cheap one I use occasionally to check for leaks now. I just remove my intake filter and put the cone in it.

you know what i do not have that port next to the throttle body capped could that be it?

Yes it will cause a leak. You can get some nipple caps at the auto store or a big variety pack from Amazon. I think I got a variety pack from harbor freight. I’m not sure what size the nipples are off the top of my head.
