5 gen whipple vac leak

[sigintel]

I got my car back today. The throw out bearing ended up completely grenading so that caused a small delay. The shop ran a smoke test on the car and could not find any leaks. I'm kind of at a loss for why my 3.875 pulley is only making 8 PSI.

Measure the pulley and see if its actually a 3.95 or 4.0?
Measure the crank damper?
Stranger stuff has happened....

Is there any update on this? Where you able to finally find the source of the leak?

From what I know, it was putting down 716whp. You won’t do that at only 8psi from a PD compressor. It was making making 10-10.5psi guaranteed. So the signal to his gauge was probably leaking, or not reading correctly.
