I ran an 8.98 in my new edge with the mods in my sig.. And that was on street tires and it was my 3rd pass ever..
Im not sure WTF you were looking at, but I went to mustangspecs.com and this is what they have for the 1999 GT:
http://www.mustangspecs.com/years/99.shtml
They even have the 96-98 Cobra's running 14 flat, only a tenth quicker than a PI GT. The NPI GT's are way behind.
My P.I gt ran a 13.8 stock with only welded in flows. Others have have squeezed out 13.7s. you said you were messing around sleeping at the light, but you reaction time has nothing to do with your et just reaction time has to do with the race with the guy next to you. You could have a 20 second reaction time and still run a 12 second pass. You et doesn't start until you roll of the staging line. Why/how would you mess around with racing and not run the car to you fullest? Bracket racing and dailing in a time is different, and I doubt you were doing this. I don't know if I have ever went to the track and not ran the hardest I could, I have always tried to get the best possible time out of my car if I go and pay to race my car. But that's me and my take on that. What's you et with your p.i. motor. Add that up, or did you downgrade from your bolt on npi to a p.i. motor
Back on to the OP congratts on the cams,

Nope I did not try to convince anyone that shortys were a good mod. Its a pi motor from a 2005 crown vic smart ass, read the beging of the post replies, I simply said I'm not spend 800 or so dollars on LTs and midpipe to gain a minimal amout of hp
With LT's and a mid pipe my car put down 255 rwhp, but that was with the slipping clutch past 3500 rpm. I haven't dynoed and tuned since the new clutch went in, but I imagine there's are a good amount of ponies left between 3500 and 5500 rpm. I wouldn't say exhaust work gives "minimal" gains.

PI cams, PI intake, 3.73 or 4.10 gears depending on highway driving, long tubes, x-pipe, cat back, tb/plenum...OR...used vortech supercharger

Hey nightfire checkout the the time for the 2002...14.7 hehehe yea you mean to tell me there's a full 7/10s of second difference between two cars that are almost mechanicly identical, with the same hp and tq, yea we need to find a site with more info, look all I said was the npi cars aren't much slower or the pi cars were that much faster. Hell you made it sound as if there was a 2sec difference in the 2 cars. The most in difference was most a full second.

It's well known that PI mustangs run low 14's stock, that 14.7 is an errant time, it had to be bad track prep or a bad driver.

Ok this is ridiculous. I was gone for a few months....did the number of newbs on here double?
EVERYONE on here who has a 4.6 should know that the PI mustangs typically run a low 14 and and NPI's run low 15's or high 14's AT BEST. This is common knowledge. There haven't been any new breakthroughs. These engines have been around for a long time and are well tested.
Sorry but um......
That's never happened. I don't mean to disrespect but no NPI GT in basically stock form is going to touch 13's. Steve McQueen couldn't run a high 13 in one. It either didn't really happen, or you've got more done to your car than flows.
How has this debate gone on for 3 pages when the facts have been well known for year?

Oops, yep I just read it again and it clearly says "My PI GT..." and I even quoted that part. My mistake man. Well yea a PI can run in the high 13's stock. I've seen it several times.
Still doesn't negate the other part of my post though:
Why are so many people still arguing about this?

I never said they where sooo slow, I SAID there as fast as nightfire made it out to be. Read again there only a 7/10s to maybe a full second faster, in the 1/4. I haven't even thought about the 1/8, but anyway I agree to disagree the a full bolt on npi is slower then the stock pi car
You ran a 14.1 with bolt ons and 4.10s.. I ran a 13.8 stock, what are you trying to argue with? You need atleast a set P.I. cams, and bolt ons to run with a stock P.I car. I think 98cobra has shown what npi headed car are capable of. He was running high 13s with bolt ons, P.I cams and intake with 3.73s. There is no comparing. End of conversation.

Not to mention 0.7-1.0 seconds is a lot in a 1/4 mile race...
I will say that a FULL bolt-on NPI would probably beat a bone stock PI, but I'm talking LT's, 4.10's, plenum/tb, and good tires. And well.....that's just not that impressive to me.
