    Help! Need advice in lowring my 1/4 mile time

    I have tried just about everything and I can't get my 60 foot time below 2.1. I've launched at various RPMS, different tire pressures and even tried Traction Control, and found that I get too much wheel spin if I try to launch higher than 2500 RPMs. Basically, my car needs more torque and grip...

    Going to the Track

    The information I posted above is what I have experienced firsthand or what I have read and heard from others. I did state that lowering tire pressure on street radials probably doesn't make that much of a difference. But it has made a difference for me when I have done this at night. My times...

    Going to the Track

    I would go with 38 pounds in the front and 28-32 in the rears (depends on how cool the track is, at night drop pressure). I tried 28-32.5 in the rears and 32-38 in the fronts and my best run was with 38 pounds in the front and 32.5 in the rear. I have heard you could drop the pressures down to...

    Help! Need advice in lowring my 1/4 mile time

    Thanks. The Shaker Hood is supposedly good for a 2-3% increase in horsepower (6-9hp) and with K&N filter (1-4 hp). So I am getting about 10hp gain from this combo and why I am reluctant for springing for a C&L CAI. I am not sure how much it would really help over what I've got. Thanks for the...

    305 hp?

    From what I have heard, the 2007 Mustang GT is about 100 pounds heavier than the 2006. Supposedly, the 2007 is using the Thunderbird platform and this was done so that Ford had one platform that could handle the 4.6L and 5.4L engine used in the GT500. I don't know if this is BS or not. Just what...

    305 hp?

    I am guessing that Ford claims that the new 2007 Mustang 4.6L produces 305 hp. I have heard that they understated the horsepower before but retracted from their 325hp claim on the new Shelby GT, which they now say produces 319 hp. Also, the 2007 GTs are heavier than the previous 2005s and...

    Are corsa mufflers worth the $$$

    Thanks for the info. I was told that I would have to spend about $800 to add a Pypes O/R H pipe that would correct the check engine light problem.

    Are corsa mufflers worth the $$$

    I have also heard that if you add and offroad X or H pipe, you will have a continous "Check Engine" light on because of a catalytic converter sensor.

    californa package

    In my opinion, it is not worth the money. Even my salesperson thinks the same.

    Help! Need advice in lowring my 1/4 mile time

    I recently got my new 2007 Mustang GT (automatic) down to 13.682 @102.29mph in the quarter. The only mods I have are CDC Shaker Hood Scoop, Superchips 91 Octane tune, and Corsa Axel-Back exhaust. My goals are to get into the low 13s and then eventually break into the 12s. However, I don't...

    Weight of new 2007 Mustang GT automatic

    Does anyone know the exact weight of a 2007 Mustang GT automatic? If I remember what I read correctly somewhere on the Net, the 2007 Mustang GT is heavier than the 2005-06 models, something to do weight added with an suspension upgrade. Plus, an automatic is a little heavier than a manual. I...

    Are corsa mufflers worth the $$$

    I put Corsa Axel-Back exhaust on my 2007 Stang recently for about $800 and something including labor and tax. I am happy with them even though I think they are a little too pricey but they were exactly what I wanted. They are loud when they need to be and no drone. And an upgrade over stock...

    My 2007 Mustang GT (automatic) turned 13.682 tonite

    Yeah, that is a great time Kooldawg and where I would like to be right now. I think my next step is buying an extra set of wheels and putting Mickey Thompson Street ETs on them. Then changing the tires when I go to the strip. But I will need a jack and a torque wrench too.

    My 2007 Mustang GT (automatic) turned 13.682 tonite

    Thanks. What's DA? Density Altitude? I think I could slip into the 13.5 range if I were to run in 60 degree temp. My best times seem to correlate with temp. 1st outing: 75 degrees, best time 13.867 2nd outing: 72 degrees, best time 13.740 3rd outing: 70 degrees, best time 13.682

    My 2007 Mustang GT (automatic) turned 13.682 tonite

    :lol: @102.29mph. Crap, I ran against a highly modded Trans-Am, cut a better RT but lost by a whisker. Two words: automatic. If I would have had a manual, I could squeezed out more and won. Here is a link to the video on Youtube: http://www.youtube.com/watch?v=7FSxYM-brjI

    My best ET, what next?

    It's heads up "Grudge Racing Night" but some are there just to test and tune for points drag racing events they have there every month.

    My best ET, what next?

    I hooked up real good on that run for some reason. The 60 foot sensor wasn't working in the left lane all night. I ran higher than normal trap speeds all night so I believe that I could have slipped into the 13.6 range with more attempts in daylight hours. I just don't run as well at night as I...

    My best ET, what next?

    I lowered my 1/4 mile time tonight to 13.740 and set a new high trap speed of 101.48 mph. I had 38 psi in the front and 32.5 psi in the rears of my stock street Pirelli radials.

    Optimal tire pressure for drag racing?

    Are these street radials? What is the normal recommended pressures and what pressures do you run on the fronts? I have heard that it is better to run higher pressures in the fronts due to less resistence during rollout.

    Optimal tire pressure for drag racing?

    So what did you find with lower pressures?
