This may sound dumb, but oh well. I installed a new boost gage, and I don't get any boost until around 2300. At 70 mph it says vacum 10, and no boost, but when I push it to the floor it will hit 10 pounds of boost. At 4000 it makes 10 pounds of boost, and I wanted to know if this is right.

i think it sounds about right, but not totally sure since i don't have a s/c truck

somebody will be around to help ya shortly though

 

I'm getting gauges install on Friday, I'll let you know.

 

The boost curve should be linear with the RPMs.

Yes that's right

 

Thanks 1JT. It just didn't look right. I always thought that a supercharger would always make boost, regardless of engine RPM.

 

if you are just cruising, you wont get any boost..
as soon as you start to get heavy with the lead foot, then the boost will start to climb..
