I have a 1998 Ford Mustang cobra svt that has a 4.6 dohc 305hp and all i did to it was put 373 gears in it, put a bbk H pipe with magnaflow catback exhaust which opens it up and a JLT cold air intake. What will my 0-60 be and what will be my quarter mile time?
your engine was rated at 305hp at the crank and perhaps turns out about 275-280 at the wheels (cold air intake and exhaust adds a little power at the crank, but really need headers and re tune of engine management system to get the increase to the rear wheels).
3.73 gears help….so your 0-60 time may be in the range of 5.8 (which was rated time of a new 98 cobra….but your engine is of course older now so and maybe a touch over 6 sec.)
in terms of the 1/4 you will run in the range of this guy, his convert is generally slower, but he is running with a chiphttp://www.dragtimes.com/Ford-Mustang-Ti…
you can get into the 12′s on a stock engine’s internals…like this guyhttp://www.dragtimes.com/Ford-Mustang-Ti…
but you will require short shot of nitrous.
he got into low 12′s with nitrous, minor engine modifications and better exhaust set up than yours, plus he is running 4.10′s
the other answerers (especially Sandy G) are seriously clueless and have no idea what it takes to run in the 11′s

You may have lowered your 0 to 60 MPH time by 1/2 second. You may not have any improvement in your quarter mile time if your SVT was properly tuned prior to your modifications. You will have to go to a drag strip to measure the benefits of your modifications…..if any.
I would say with a set of drag radials and some practice on getting the perfect lauch, you would be in the mid to high 13′s. My buddy had a 98 with 456′s and launched at 6g’s and ran 8.40′s in the eigth,
This is a light car so hp to weight ratio will be pretty good. Your 0-60 should be 5 to 7 seconds, making your quarter mile time in the 10′s and 11′s.
