Vortech Btm - The Details

[stang89bidges]

Looking for the specifics guys.

1. How do I set timing?
A: Do I need to turn the boost control knob to 3 when setting timing?

B: It's mentioned in this article to set knob to 3 to begin with but for what reason? Supercharger Ignition Boost

2. Final setup?
A: I'm thinking of setting initial timing to 10°, total timing to around 25ish, and setting my BTM knob to 1° retard. Sound good?

Get the car warmed up, find the spout connector it's on the wiring harness leading to the dizzy. Pull the spout and put it in your pocket not anywhere else IN YOUR POCKET they are hard to find. Loosen the bolt on the dizzy hold down, get your timing light hooked up. Start the car and point the light at the right side of the timing pointer looking down on the balancer. Twist the dizzy till you get 10* btdc.
Shut her down reinstall the spout connector.

Set the btm to 3* drive the car if no pinging or detonation is present then move too 2, then to 1 take it slow and feel it out. This will keep thing from going boom!

How much boost are you running?

Don't forget to tighten the dizzy back up

I'm not running the H.O. pulley so I'm doing 6# boost max.
