Specter 100mm intake
Hurst short throw shifter
Mickey Thompson et streets or Hoosier bias plys on 16 inch pony rims 27inch tall
Full eibach suspension
Also what are the estimates with all those plus long tube headers and ***** thumper cam or frpp hot rod cams
Also what's the stock drive shaft length is there a different one I can put in other then an aluminum one I don't really wanna spend 6-800 on a driveshaft
Thanks for all the info
Just my personal opinions, some of which are based around previously owning an 07 GT and helping build some other friends GT's
Stock RWHP will be between 255-260
The exhaust + CAI + tune should get you back to the 295-297 HP range
Not sure what brand of 3.90 gears you are looking at, but if they are Motive or Yukon, i'd stay away, stick with FRPP gears. For a manual, 3:55 or 3:73's are plenty for the track and DD.
I also wouldn't skimp on the tuner and get the SCT as they are light years ahead of Diablo tuners and a good chunk of the tuners write for the SCT programmer, which makes things easier when it comes to upgrading or re-writing your tunes.
Look into one of the package deals offered by Brenspeed, Steeda, VMP, Lethal or AM.
UDP's may get you 5-10 HP
Long tubes and cams may get you another 20
all in all your looking about 310-320 RWHP, the biggest benefit will be the drag radials, which begs the question...why would you put all of that extra HP into the car and not put in a one-piece drive shaft?
There aren't alot of options, but what you are doing is replacing the 2-piece for a one-piece, which means more transfer of power to the rear wheels.
With this setup and practice and a couple really good launches you should be hitting high to mid 12's. I would expect 12.8's on average, given driver mod and elevation, air density, etc etc
