classj,
To not be a total dick I'll say if Brent says he did it I'll give him the benefit of the doubt, but I'll still be doubting it... this means we have a lot of under performing Cobra's running around.

I think Brent addressed this already in a past issue. He claims it is true. He was running street slicks or slicks at the time and it was a hard launch at very high RPM. I think he said 5 grand or so.
Seems a bit of a stretch. But if he ran the time and is not BS ing. God bless him. But I wouldent expect times like that without a ton of track time, a really nice day, a perfect launch, and some sticky tires.
But I have seen a couple guys turn 13-13.2, on 18" street tires with a tune and intake, so you never know. Best stock times I have seen are 13.5's so knocking off .3-.5 for 30 RWHP doesent seem too unreasonable. Add slicks and good conditions and driver and it might be possible.

The part that sticks on one's throat is the claim that a Mustang GT went 12.8 @ 105 mph full weight "with only this air intake, our custom tune, and a pair of MAC mufflers", while according to well informed sources it also had street slicks that are not mentioned in the claim. And if that's the case, then it's possible that other mods were also installed, e.g., undersized pulleys, off road H or X pipe, lower gearing, aftermarket clutch, and who knows what else.

I was told that his car ran 12.50's with the 4.30 gear, underdrive crank pulley electric waterpump combo, the CAI and a 93 tune, MAC axlebacks, and the ET Streets. 11.90's on the sauce.

Have you actually put your car on the dyno? You should see closer to 25rwhp gain with the CAI and tune. When I had mine on the dyno it made 267rwhp stock and just over 290rwhp with the CAI and tune. Now why in the world is your car so heavy? I have weighed mine after the built engine and S/C and it weighs about the same as what you say yours weighs. Your ET is just on par with what our cars can run stock but your trap speed is much higher so your ET should be better then what they are. Now you have to remember that every run is different especially since there are so many variables that will affect your times.

So now our cars have lost weight and the Cobra's have gained weight... lets see, an '03 CObra... 390 crank hp and 3600lbs, my car weighs 3560 and makes maybe 325 crank hp but it stands a chance to run as good as the Cobra. Not in this lifetime.
Yes, my car runs about the same trap speed as Brent's but that does not mean my car has 12's in it at full weight with street tires and 3.55 gears, maybe a 13.3 with a perfect launch and great tires, but no way a 12.8.
Are we so gullable that we believe our cars to be that fast with so little done to them?

The cobra makes more power but it weighs about 200lbs more. The curb weight for our cars is around 3450 while the cobra weighs in at 3665. It also has the IRS to deal with, which is great for handling but not so good for drag strip runs. Now I don't see why you think it is so impposible when your trap speed is equal to Brent's.

Ok, 25rwhp, so how does this shave so much time off the car? Also, how is my trap speed MUCH higher? I know this, my car, your car, Brent's car and everybody else's Mustang GT WILL NOT run 12.8 at full weight, stock gearing unless God himself gave her a push. Agreed, many variables affect elapsed times and trap speed, but as I said, these cars will not go 12.8 with so little work done to them in full weight trim.
MAYBE 13.2 with a freak of nature run but the power needed to go 12.8 at near 3600lbs in our cars is beyond what a CAI, Tune and Mufflers will provide. Hey, I want to say my car can run 12's as much as the next guy, but experience and facts say it won't.

RE: Can this be true?
I don't know, I don't see this claim as being THAT farfetched. If a bone-stock car with the street tires ran a 13.8 with a great driver behind the wheel, I don't see how it's impossible that Brent ran a 12.8 with tires, a CAI, and a specific drag tune. Is it improbible? Yeah, but get a great driver in there and a tune set up JUST t drag, I can see it.
Just ny 2 cents.

OK I know this is not 100% accurate but it will give you an idea of what a perfect run should get you if you take 3600lbs for the car and 290 for the hp plug it in and it gives you 12.87 for an ET.http://www.nationaldrivetrain.com/calcs/dragcalc.html Now that is without driver weight but it also doesn't take into account the drag radials. And as I've said before our cars are not as heavy as you think they are, I have actually taken mine to a weigh station and weighed it and with me in it it still wasn't as heavy as you think it should be. I even have the shaker 1000 unit which adds weight, spare tire, and full tank of gas.

Brent left me a voicemail stating he's leaving at 6100rpm on drag radials, power shifting and THAT's why he runs 12.8, I'm going to return his call but I still don't agree that it's possible with the following to run 12.8, ET Drags, CAI, Tune, Mufflers, 6100rpm launch and power shifting, this means his car stock prior to any of this was already under 13.5 and his 60ft's are where cars making much more power are... this should be an interesting phone call.

Please update us after the phone call...
All this energy about 1 sec, does it matter? I'll give Brent his due, he sure works hard at it. Maybe he should have put a disclaimer at the end of the post "Individual results may vary,yada yada, yada."
I have the set up he mentioned with the exception of Borla axel backs and an 89 tune.
Incredible performance, all I'll ever need. I don't plan on taking my car to the track, just don't see the need to abuse it for an ego boost. But to each his own, and what ever trips your trigger, and I say that in all due respect.
What makes the "car enthusiast" effort so interesting, is we all have different styles, tastes and interests.
