2001silverado364 Posted October 7, 2011 Report Share Posted October 7, 2011 Go out and stop at a red light, floor it until you reach the speed limit(at least get out 1st gear), and report the highest value you saw on the gauge during that time.

Huh? I should probably mention its a boost/vacuum gauge so what number do ireport at idle its at the 20 on the left Quote Link to comment Share on other sites More sharing options...
2001silverado364 Posted October 7, 2011 Report Share Posted October 7, 2011 Do what? You don't make boost at idle, you may be pulling 20 in. of mercury. But that numbers, not needed. Quote Link to comment Share on other sites More sharing options...

SSThunder Posted October 7, 2011 Report Share Posted October 7, 2011 Let us know the pulley size and we'll tell you what your boost should be. If it's got the stock pulley you should hit 5 on the boost gauge. I went with a 3.0 pulley and could hit 7 on my boost gauge. Some se a little more. I think the pulley should have a number on it telling you the pulley size. Quote Link to comment Share on other sites More sharing options...
