I posted this question in another forum but responses are few so I decided to put it here as well. I just put on a Fast Big Mouth 92mm throttle body. Does anyone know if it only has the 4 corners bolted or is there a bolt that's supposed to be top center as well? I only have 4 on it and I have what sounds like a vacuum leak possibly caused by not having this 5th bolt? Anyone familiar with this? I didn't have extra parts left over after the install though.

Don't know if it helps or not; but the nitrous plate kits for these do not have a hole for the 5th bolt, so I wouldn't figure it to be necessary.

Could very well be the problem
