Somewhat Bummed about my new engine

[jdredpony]

I have a 93 lx Mustang. I just purchased a 5.0 e303 gt40X head 340hp Ford Crate engine and its installed. I went to the track last week and was very dissapointed in my times. The best I ran was 13.5 @104 with a 2.03 60'. Last year I ran a 13.8 @99 or 100mph with my original 5.0 with boltons. In addtion to the stock motor was new Nitto 555r and a new h/d trac loc diff and 31 spline moser axels. I was hoping to be in the 12's with this set up. Do you think I need this car Dyno tuned? Do I need a new computer? I just cant imagine I went from a 225hp engine less bolton to a 340hp engine and its not a ton quicker.Shouldnt I be able to smoke the tires in 2nd gear?? I have a cobra intake on my engine and Im wondering if its robbing power? Should I go with the edelbrock intake or is the cobra good enough. I have the timing set @ 14deg and fuel pressure is set about 38lbs. Ford racing told me to use 30lb injectors but the people who installed the enigine disagreed and used 24lb. Could this be a problem?? Im sure the amount of fuel in different if Im using 24# injector @ 38lb fuel compared to using 30lb inj. with 38lb fuel press. right? I need help!!!! My bolts on extensive. 76mm C&L mass air 70mm throttle body, underdrives 3:73 gears, Alumin. drive shaft, elec fan, moser 31 spline axles, boxed rear upper and lower control arms, Steeda sport lowing springs(which I know dont help with drag racing) Cobra intake, shortie headers, highflow cats with X pipe, Magnaflow cat back, MSD coil, K&N cold air intake. This car should be in the 12's in my opinion. What do you think??
Sorry, I know this is long but I did not want to not leave anything out
Thanks

Rico or Jim will have something useful to say but not me lol other than I think you should be doing mid 12's.

Get more seat time.

you need to get it tuned, i was running 46 psi fuel pressure, and a hell of alot more timing on my stock bottom trickflow toped motor, never tracked it but it was a big difference over stock.

is the maf set for the 24 pounders? what fuel pump are you running?

[American Psycho]

If he repsonds, Rico i will be amazed

[jdredpony]

yes i really need it tuned. So you think an increase in fuel and timing could make quite a diff.?
yes the maf is calibr for 24#
255 on the fuel pump.
I know I need more seat time, but I thought with that much extra power I would really feel so much more power..
Thanks guys

just on a stock 5L if you bump the timing a few degrees from where ford left it makes a difference. you need a tune, a better 60' would be nice but the tune is what your missing.

if you are capable, bump the fuel pressure to 40 and advance the timing a few degrees at a time, if you have some free track time to test your changes or go by the seat of the pants dyno aka adjust till it pulls hard, or a real dyno if you want.

ps post pics of your car.

your 60' is terrible..

yea those times accauly look about right with your 60 fooots. 2.0 ........ lol learn how to drive it. i was also gona say get it tuned. get some mickey tompsins in the rear.

[jdredpony]

I know my 60' times sucked. I didnt heat the tires. I only did a small dry burnout. I was trying to launch at different rpms. I started out at 3000 then jumped to 3500 (severe tire spin) then back to 3000 rpm's I want to get the tune and heat the tires in the water and see what happens.
Thanks for the info
