If you let the car run for about 5 seconds then turn it off and start it up again, the noise isnt there the second time.

I was told the computer acommidates for the timing advance because these heads operate with different amounts of EGR gases. I heard that I could probably use the heads without the computer by using a timing adjuster. I'll be using a supercharger with 10 psi and a custom chip to change the rev limit, so how much do you think I should advance the timing with the supercharger to keep from having to use the computer or what exactly should I do?   On 02.17.2004 Anonymous wrote: I HAVE JUST GOT SOME LONG TUBE HEADERS FOR MY 2003 GT DO YOU THINK I NEED TO USE A BETTER HEADER GASKET OR SHOULD I JUST USE THE ONES THAT CAME WITH THE HEADERS THEY ARE BBK.   On 02.17.2004 Anthony Johnson wrote: What type of MAF do recommend for a stock '03 Mustang GT Convertible 5 speed?

In addition they were instructed to weld the axle tubes nearest the differential cover. When I showed up to get my car (4 1/2 days later) the shop ended up only bolting in upper & lower torque box reinforcements and welding the axle tubes. They complained about how much work it was and admitted that additional work needed to be performed because they ran out of welding material. Anyhow the mechanic who did the work said that he drained the gear oil to make the welds and that it was really low. About 2 weeks earlier I installed a heavy duty aluminum SVO Motorsports 8.8 girdle and filled with new gear oil & friction modifier. I seriously doubt this is accurate (no leaks & plenty of gear oil was added). Immediately following the shop's work the car made grinding/rubing noises from the rear end when the car is powered (normally accelerated) with the wheels turned to lock either left or right. No noise/rubbing/binding is noticed while coasting or decelerating. My friend who happends to be a former racer says that my differential is most likely shot but also pointed to the possibility that the tubes could be warped from the welding or even a possible bearing problem. The car just hit 40K and has never been raced on the track and rarely on the street not has it been in any accidents. I've checked exhaust & it's not rubbing. Any ideas?

So they pretty much told me that I needed to have a chip or a timing adjuster to correct the timing. Long story short...I had them put the stock pulleys back on just to make sure the car was fine. That did the trick. My question is....I thought the pulleys were just a bolt-on upgrade with no additional modifications? Would a timing adjuster do the trick? Do I need a chip?

Now that I have changed to mac h pipe and flowmasters my car has come to live down low, and when I added the upper intake afterwards it really made a difference. question one is why is my car running so rich now, and what is the difference in running lean and rich. Second question is why would my car run so much better with the h pipe and they swear the x -pipe will produce more hp? I had no exhaust leaks before and I have no means of a dyno. I have to go back to drag radials, because my car now spins on nitto 555's from a 25 mph roll and through second thats on the street, it did not do that before the h-pipe and upper intake.

I noticed, while we were talking, that your cowl hood is wide open at the rear. I assume you know that the original purpose of the cowl hood is to allow the high pressure area at the windshield base to pressurize air into the intake. Since Mustangs don't have fender vents like T/A's and Vettes, I was wondering if you or anyone you know has tried blocking off the upper grille opening and the rear of the cowl hood to prevent air building up in the engine bay. The lower grille should provide plenty of cooling air for the track, and you might see 1-2 miles per hour.
