Supercharged VQ37 Goes BOOOM

Kyle@STILLEN · 03-22-2011, 07:27 PM

Hey Guys,

Just wanted to drop in here and post up real quick. Obviously seeing as how fresh this is, we're looking into it as well. As it has been mentioned, this kit is intended to run at 8 pounds of boost. Why it was running over 9 psi and then even further, why it went up to 10 psi after the installation of headers is very unusual and we don't have all the answers yet. Many of you will remember that when we developed the supercharger we mentioned that most of the time the addition of headers will lower boost pressure. We have found this to be the case. Now we're curious why boost actually increased after installing headers.

The kit was designed and tuned for 8 psi. We need to know why the car was running over 9 psi and then even bigger question why it went over 10 psi!
