Ta Da...14.94..now Heres The Problem....i Had Some Extra Parts Laying Around....bolted Them On...a 65mm Tb..spacer..76 Mass Air Cal..4 24 Lb Ers..installed 24 Lb Ers...timing At 10*....so Heres The $100,000 ? What The *&%! Happen...car Now Runs 16.10..the Car Runs Great...just Not Where
I Think It Should Be....any Thoughts........help...im Going Crazy...
Going Back To Stock Is Not An Option...

First off, go back to the 19 lb injectors. They are good till you hit about 300 rwhp. Bump your timing up to 13-15 degrees - or till it starts to ping on hard acceleration.

You will find out that bigger isn't always better, especially with a stock motor.

ok thats what i thought...but ...i am going to add ..heads.intake and cam..will this still be ok..

[frdfandc]

Yes, you will be good with the 24's, but I'd wait till the heads/intake/cam are installed.

Also, try running a short belt at the track...by-pass your air pump and power steering...another trick, I dropped 2 full tenths using an underdrive crank pulley and an electric fan...and I was going into a 15-25mph headwind...

I don't know if you're familiar with the 1-D-1 shuffle but that will help as well...I used to manually shift mine at around 4800 from 1st to 2nd and at around 5100-5200 from 2nd to 3rd

My 3250lb t-bird with my 230lb butt went high 14.30's into a head wind all night long...that was with a stock convertor, 3.73's, electric fan, underdrive crank pulley, K&N panel filter, 14* of timing(on premium of course), MSD coil, full-length headers and off-road h-pipe...there was NOT much money into that car...BTW, an aftermarket trans cooler ran in series with the stocker will help SOOO much.

Good luck,
Don

So your best is now a 14.60. Great! What type of Mustang do you have, 'vert, hatch or coupe? Do you know how much it weights?

I've got a '90 LX Convertible, 3400 lbs (3550 lbs with me). I did a best of 15.50 last summer with only a CAI, 65mm TB, 76mm MAF & electric fan as upgrades. I've got functioning A/C & 3.27 gear. I'm just trying to compare to others.
