    1st Performance Mod Completed! (Magnaflow X-Pipe & Cat-Back...) "Wow"

    Thanks for the write-up. :flag: You have a good start on helping your stang breathe better on the exhaust side. LT headers, of course, should be next. I did not notice any intake modifications. You may want to consider a K & N filter, along with a larger throttle body and plenum. A...

    4.10's without dragracials?

    My 4.10s by themselves didn't cause too much traction problem. When I added some horsepower through bolt-on mods, I now have a problem. It's time for some drag radials. My situation may be different than yours; I have a convertible with an automatic.

    300rwhp from a 99-04 GT, what's it take?

    260 rwhp from these mods: C&L Plenum C&L 85MM MAF C&L True Flow Pipe BBK 75MM TB MAC ProChamber If a stock 5-speed dynos at 218 rwhp, that means that you added 32 rwhp with the mods listed above. Without a tune, that hardly seems possible.

    Exhaust Question: Which increased hp the most

    On the exhaust side, most horsepower is gained from LT headers (15-20 rhwp)and a performance mid-pipe (8-10 rwhp). The cat-back exhaust system is primarily for sound, although some gains can be expected. At www.mach1review.com, they compared the performance gains of three cat-back systems on a...

    Got my GT dynoed!

    I am assuming that you have a manual transmission. When stock, these dyno around 218 rwhp. That means that you've added 22 rwhp with just intake mods. That's great! A mid-pipe will give you another 8-10 rwhp, while LT headers will gain 15-20 rwhp. The catback exhaust will be around 6-8...

    0-60 times are not good, is it me or my car?

    A stock GT with a manual transmission can run 0-60 mph in 5.5 seconds. These results are listed on a website that posts the 0-60 mph times and 1/4 mile times of a variety of cars: www.ssmoparmuscle.com

    12-sec Mustang under 2500?

    Jay, that's incredible. You engine mods probably added only 20 rwhp, yet your are able to run a 12.8 quarter mile. Congratulations! What do you think is the greatest factor(s) in improving your time?

    Picking long tubes headers

    If you have an automatic, you can use Hooker, Kooks, and MAC. BBK appears to be the header of choice for those with manual transmissions. I chose Hooker for my automatic because of its reputation for quality.

    Cold Air vs. More Air

    I'm still trying to decide whether to say n/a (heads and cams) or go with a supercharger. Playing with the air filter gives me something to do in the meantime.

    Cold Air vs. More Air

    I agree that there are bigger fish to fry. You can see from my signature below that I've fried many of these fish. I understand that horsepower gains come largely by making the intake and exhaust more efficient. Aside from a catback exhaust, I've done all the major bolt-on mods. I'm...

    Picking long tubes headers

    I bought the Hooker LT headers with ceramic coating. I also bought the matching o/r x-pipe. With this combination, I gained 23 rwhp. I've been very pleased with them. I still have the stock cat-back exhaust but the headers and x-pipe by themselves made the car a little louder.

    Cold Air vs. More Air

    Anyone else remove the airbox? My car seems to be running fine. It has been cold here in Minnesota though so its hard to tell if the heated air in the engine bay will hurt performance. I like that fact that my engine has access to more air but I suppose that could cause it to run leaner. I...

    Cold Air vs. More Air

    I drove my car tonight with the open air filter (minus the air box). It ran fine but I could not tell if it had any more power. It's interesting that the better aftermarket MAFs, like Pro-M and Granatelli, use open air filters. On the other hand, it is hard to argue with basic chemistry...

    Cold Air vs. More Air

    That's the plan but I wondered if anyone else had done it.

    Cold Air vs. More Air

    I know that there is a lot of debate about the air silencer, whether to remove it, keep it, or shorten it. How about removing the air box? Rather than worry about grabbing air that is a few degrees cooler, allow the air filter to have access to more air. For example, the Steeda High Flow Air...

    Anyone with a C&L Trueflow inlet pipe?

    I have the C & L True Flow Inlet pipe on my 2002 GT. When I installed the Steeda strut tower brace, it fit with 1/4" clearance. I think that the Steeda brace is taller than some others.

    Why do Grand Prix try to race me?

    I do have a friend who does this with his 2004 Cadillac STS. He just wants to see how fast the other car is. I doubt that the kids I run into are that sophisticated.

    Why do Grand Prix try to race me?

    I can understand why no one wants to race a Cobra, Corvette, or Viper. It's because the race will be a total embarassment. It's futile to race cars that are totally out of your league. That's why I don't understand why family cars and ricers want to race the Mustang GT. I don't have the...

    Why do Grand Prix try to race me?

    There is an internet site that records 0-60 mph times and 1/4 times for most cars: www.ssmoparmuscle.com. I have found them to be fairly accurate. For a 2004 Pontiac Grand Prix GTP Comp., they list 6.6 seconds for 0-60 mph and 15.00 seconds for the 1/4 mile. This is a definite improvement...
