Tom’s Tech Tips – Vacuum Pumps
Now you can see the entire GZ setup as installed the 8-second Duster. Breather tank was easy to mount. Be sure to mount it where you can drain the tank after each weekend.
Did the GZ Vacuum Pump Kit make my car faster?? Damn Right it did! Here are four ET slips: the two on the left are with the GZ pump not working (belt removed) and the two ET slips on the right are with the pump belt on and engine pulling about 11-lbs of vacuum during the run. How often can you pick up a solid tenth on a already powerful engine for under $800.00? Thanks GZ.
