just a quick review.....before the tune and full fuel upgrade,my truck was making 480RWHP from a combination of heads,cams,full exhaust,supercharger with 10LB boost and a 100shot of NOS.
i decided to upgrade the fuel system by changing the 42LB injectors to 60LB and add a second 255 fuel pump(discarding the 255 inline fuel pump)and changing the supercharger pulley to get 14-15LB of boost.
i wouldve been happy if i could get 450RWHP but with so much tweaking..we ended up with 487RWHP and 490WTRQ.
my main concern was that we had to up the RPM redline to 6500RPM(from 5500-6000RPM depending on which gear im on)
having a stock bottom end(except for the forged crank)after the final numbers were in from the dyno..we decided to back the RPM redline to a decnet 5000RPM with 13LB of boost until i can bulletproof the bottom end next year.
heres pretty much he we set it up..
WOT
1st gear = 0-45MPH
2nd gear = 45-80MPH
3rd gear = 80-120MPH
4th gear = 120-????MPH
i had to try it out on the interstate but it was hard to go beyond 120MPH without getting into traffic.
so heres my dyno sheet and a small video.
(the SUV 's speedometer tops out at 100MPH but my navigation system also keeps track of my speed via GPS)
my GPS readout(max MPH is recorded)(i didnt have my videocam when i hit 120MPH on top of 3rd gear)
video..
BTW..this is a full size ford expedition :D :D
