I have stock exhaust too... Just modified

 

^^^ How is your stock exhaust modified? New mufflers?

 

The stock exhaust is not as bad as you may think. I'm sure I could pick up a little more hp/tq with a free flowing exhaust but I can't deal with the added noise. I used to run a T1R v3 70 then went 3in. The 3in produced so much noise and vibration that I was getting false knock voltage. We tried to work around this but it was not safe. I may go back to a single someday, but at this time it's easier and cheaper for me to run more boost.

 

I cut the mufflers open, sawzalled the baffles out, then welded the mufflers back together.

 

Now this is a thread full of titans and one I know I could a lot from on how to properly build my S!

 

I'm at 390 it was a warm day I probably be at 395 in winter
I am running Vortech, 12lbs of boost, aem ems, meth injection, stock motor exept for springs and retainers, I have an 07 so I had to modify a return fuel system, new fuel pump, 70mm exhaust and I have stock header and cat. All done and tuned at autowave HB by mike and Shane.dyno dynamics

 

Nice numbers but wrong dyno manufacturer. AutoWave has a Dyno Dynamics and not a Mustang.

 

What size is your pulley?

 

yes you are correct it is a dyno dynamics, the dyno at vortech was mustang!!ooppss
3.6" is the size i believe
