14-15 with an E cam. The Stage 1 should be a little less than the E.

im guessing ur talking about me...it varies around 850-975 according to the stock gauge. Weird thing is it used to be around a consistent 13hg at idle then i took on the highway for the first time with the new motor and since after that it stays around 14-15. My stang has the weirdest situations, one i have right now is I have 65 degrees of timing with the spout connector in or out haha

haha holy ****, that doesnt sound right. hey mustang darren has it always been that low? Ive had more than one person tell me that 10 inch of merc is too low for a cam like a stage 1 or ford alphabet cam.

It's probably due to the supercharger. It quickly goes to 0 when I get on the throttle and starts making boost under load.
 

Look Its Aaron

Your car looks like it came straight from Mexico.

9-10" with my fairly large FTI custom. Around a 950 rpm idle. I may have a slight leak at the lower manifold though due to my heads being milled around .035" and my block being 0 deck.

The 408 in my sig has 14" at cold start, and 16" once its nice and warm.

My general cam specs
Lift w/ 1.6RR .513/.526
Duration @ .050" 230/236
LSA 112

When do the factory vac accessories lose effectiveness?
What is the min vac needed for vac assist brakes?
