I ran 7psi for a while with this setup. I had an intercooler on the shelf, but it needs to be completed. I will tell you that even without an intercooler I had lots more power!
14.3@102.5 MPH with just that 7psi with no intercooler.
That was with babied take-offs in first gear to save the transmission. No wheel spin, no slipped clutch...just a normal take-off like you'd do on the street. I wanted to see what it would do without any extra transmission abuse. I have a torsen LSD and spec stage3 clutch sitting on the ground next to my transmission right now so I will be able to push for some better times in a few weeks.
My best N/A time was
14.86@95.96 MPH and that was with a full blown take-off with wheel spin all the way through 1st gear and little into second gear.
A gain of almost 7MPH in the trapp speed and a minimal .5 second in the quarter given the conditions is very good for a mild boost non-intercooled SVT. Yes, there is room for improvement that is why I have just about everything for the intercooler now. I will put everything back together, then I will install the intercooler.
