What you think?
 

I was wondering about my 87 mustang.....Im gonna put underdrive pulleys,flexlight fan.and a cold air kit,then im gonna put a set of either mac shortys or hookers on it with an h-pipe and 2 1/2 inch pipes out the back,then im boltin on a set of street radials. What do you think i will run?

Oh its alos a 5.0 ho and a 5-speed.

I say a 13.9-14.0 with agood Driving
That flexlight fan might be Taking some of the power away But they do work good, Cool the motor Down better than the stock Fan Clutch does

depends on the weather and your driving skills but good weather and good driving ill say 14.3-14.5 throw a set of 4.10s and youll be plowing into the 13s.

im also puting a hays clutch and hurst shot throw shifter if it makes a differnce.

im thinkin i can run either a 14.0 or a 13.90

You will be surprised...I agree with Causing Havoc...low to mid 14s...its totally different from the street-launching is different...ect.

Not trying to knock your ideals -just a reality check from someone who was in your shoes...I was so confindent about my skills and mods that 13.8 seemed plausible..not..best I could muster in the 60ft dept was 2.1 and I ran a 14.7 ....by the middle of the summer(a while back) I had it down to consistent 13.9s on slicks with a 1.80 60...

Don't be dismayed-practice make perfection..thats where its at...plus slicks help!LOL

good luck

im thinkin a 14.0 or 13.90! I can drive the car pretty good to im able to launch at 4000 rpm with only spuealing the tires a lil bit.
