Now that the truck is broken in, I have been getting on it testing everything out before I go to the dyno. My pulley combo on a stock engine should produce around 13 lbs of boost with Novi2000. My engine is not stock. My heads are fully ported and intake has been cleaned up, x-metal tb, forged pistons/rods, bassani headers, no cats, true dual 3" exhaust, custom cam for blower, etc.
With the boost gauge hooked into manifold vacuum (along with brakes, and everything else that needs vacuum or boost) I am getting a max of 5lbs of boost. This doesn't seem high enough. I next get a reading at the pipe from the blower to the intercooler and this shows no vacuum and constant boost pressure of between 2-5lbs, even while just driving normal. When on the gas hard I got max boost of 10lbs. So to see if it is my intercooler causing the problem I get a reading from the pipe that goes between the intercooler and the TB and it goes to a max of 7.5lbs of boost.
My intercooler is costing me 2.5lbs of boost?? Does that sound right?? And then I am loosing another 2.5lbs once into the intake??
Is this normal or what the heck is going on???
