Default Intake pressure tester

I want to put one together and was wondering if anyone knew of a writeup for the TT to make one. I need to know more precise measurments for the outter diameter of the maf where the tip connects. I did a rough measurement and got about 3.5 inches.

Thanks,

Ian

You can make your own or just get a built one for $30 here.

I sorta copied teh design of the one sold at the modshack. Most expensive part was teh gauge I put on it, and you don't even need one, just regulate your air to a reasonable number (no more than you'd boost is smart). Got a 3" PVC fitting, and a screw in cap.

lower fitting in this pic, with a cap that would screw in. Make sure the smooth end is the 3" part if you have a 225, or 2.5" if you have a 180. You'll also want a radiator hose clamp big enough to clamp your intake to this, and it doesn't hurt to find a way to texture the fitting, or put a small lip on it so it can't slide out, theres still a chance, even if its hose clamped. Oh, you'll also need a male air fitting. Careful drilling the PVC, or at least don't do it like I would, because the last 2 times I've drilled PVC, I've cracked the ****.

It's so funny that was your idea. I went Lowe's and found the exact same thing male smooth end and female screw end. I already glued thescrew cap in. I'm going to autozone tomorrow and buying somevalve stems so I can try and use a traditional electric tire pump. I don't have a tool compressor so an npt fitting would be kinda useless to me. I'll just use my boost gauge to measure the pressure. Total cost is going to run me about $11. Awesome :-)
