Here's the deal with the 5.0 Cobra's. They were underrated at 240hp. The computer is literally costing them 20+hp. The computer they have stays in closed loop for 7 sec, or nearly an 1/8 mile before it goes out of emissions mode. That kills the acceleration curve. LOL. The car is still trying to pass emissions at 70mph with the pedal to the floor.
The reason why the Cobra's got 24 lb injectors is beyond me. 19lb injectors are fully capable of supporting 350hp. I think it was just a "cool" thing.
Most people are able to dyno 260rwhp with the 5.0 Cobra's with just exhaust, and a couple other little bolt ons. Adding an E cam to the Cobra can produce over 300hp, and that will put you into the real low 13's/high 12's with gears and traction.
You may want to run the idea an SN95 needs cam, heads, intake to run 13's past Mustangbelle306. Her 94GT was able to rip off a 14.0 run with 4.10's & exhaust. How many times have you seen your car quoted as a mid 14 car 90dpscoupe? I know for a fact there are a ton of people running 15's with their fox 5.0's. Even some people with SD. I can't fathom for the life of me why, but appearently they do. My tired 87GT pulled off a 14.19 on the Gtech at 103.8mph. Take 4mph off for high reading, and that's still 100mph trap. I wasn't even tuned. The dumb plugs, cap and rotor were so bad it had a slight miss on low rpm acceleration. Air filter needed cleaning, and I had 100lbs of **** in the back. Running near stock with 146k. In fact, with my 2.95:1 1st gear ratio, I was actually a lot slower out of the hole than with the stock tranny. If the Gtech is anywhere near accurate, with a gear swap, and a tuneup (which has now been done) I've got a mid 13 Stang. You never know until you run it, but that's crazy for the kind of mileage I have, and the feeble amount of mods.
If you put a cam/heads/intake combo on an SN95, and you do it right with a matched combo, with a good driver it's inexcusable to run anything higher than a mid 13. The car is well capable of running high 14's from the factory.
