i guess in a perfect world on paper all motors are as buildable as the next, but given the fact its already blown and only has 3 tenths on a n/a stock ls1, you might conclude that it just doesnt perform as good as an ls1 mod for mod.
either way though, i love the car.

"You might conclude that it just doesnt perform as good as an ls1 mod for mod."

I have to disagree. For less than $100(lightning pulley), 40 more RWHP is had. Do that with an LS1. My friend's car ran that 11.70 for less than $1000. That's one hell of bang-for-the-buck! I've thought about trading my Z in for one, but can't seem to do it. Me<<<<<A HUGE fan of the LS1!!

 

The reason why the mustangs are only .3 tenths faster than a stock ls1 is because of weight. That iron block is heavy. And most Mustang owners I know weigh over 300lbs <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> I'm sure that that doesn't help either. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

I can already see this post turning into one of those 10 page arguments about which motor is better.

They both have their strong points, and if people will keep their heads out of their brand loyal asses they'd actually realize it (Mustang/Fbody guys alike).

I watched a friend of mine this past weekend at Gainesville run 12.02 @ 117mph in a 03 Cobra with a shifter, cold air kit, catback, and Xpipe. He pulled a 1.83 60ft on the factory Goodyears. It had the stock pulley (believe it or not, we actually measured it to make sure he wasn't lying). It was good weather, very cold and a sticky track. He paid less than $700 for all those parts. That Lightning pulley would have put him solidly in the 11s... next week <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I've seen LS1s run mid 12s with a converter, lid, cutout, and drag radials. A nitrous kit puts them in the 11s. I've seen a friend's full weight cam/intake/shorty header/converter/3.73... 99 TA run 11s @ 114mph on motor, with Nittos.

We all know how potent the LS1 is, either behind the wheel, or when we've stared at tail lights as they left us wondering what the hell happened.

We're finding out how potent the 03 Cobra is now also. Sorry, but 600+rwhp for $4000 in parts on the stock bottom end doesn't seem like it's lacking in the potential department to me. You can say it comes with a blower stock, you can say it has a "built" motor stock. Seems to me it was built for more potential out of the box.

Mod for Mod doesn't really add up because one is blown the other isn't. One was built for boost, one wasn't.

Roarin - Most LS1 owners I know couldn't drive a greased noodle up a dog's ***... but that just makes it more fun for me at the track <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

*fears he just opened a huge can of worms, lol

I thought I was the last bastion of sober reasoning and clear memory. Thank you!

Perhaps not many here ACTUALLY remember the 60s and 70s, but there were a number of FACTS back then. One is that today's most vaunted motors and cars were NOT the quickest on the street. The street Hemi was dog snot on the street. The 440 was quicker. The LS6 was so rare that no one gave a crap about it. There was more fear in the 396 versions because they were common and easy to mod. And the Ford 428 was about the quickest stocker on the road. The 68 428 SCJ drag pack was STUPID fast.

The point? Blind brand loyalty is just ignorant, yesterday AND today. It's denying the fact that fast FAST street cars existed with about every badge imaginable, and I didn't even cover the Bu's, Olds, AMC (yes, AMC), and the 03 Cobra is no less deserving of respect.

These things are just silly fast and powerful guys.

Although most '03 owners opt for the VASTLY cheaper 2 1/2" exhaust instead of the 3"; I'd say that makes a decent difference and probably why there are some slower '03's out there.

3" REEEEEEALLY opens up their cars <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

BUT . . . ONE THOUSAND DOLLARS for just the stainless exhaust is highway robbery <img border="0" alt="[bomb]" title="" src="graemlins/gr_bomb.gif" />

 

$1000... what the hell kind of exhaust is that ?

The good part is that 99-01 exhaust fits the 03s. That friend of mine got a $450 Magnaflow catback for $300 <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

It ain't a Mustang unless you can buy cheap used parts for it <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Having dual fuel pumps only add to the power that is available. Pushing 600rwhp with the complete stock injectors, and fuel pumps is no problems for this car. And with a built Manley h beam connecting rods along with forged pistons and the steel cobra crank(best 4.6L crank you can buy for these modular cars) the bottom end can take the 600rwhp.

Im ot sure who said that these heads flow good, but they truley due. DSS a big company for these modualr engines also does head porting work for the 2/4V 4.6L's. They can take the stock 4V head and make it flow 57% better for only $1200. Imagine then how the heads would flow along with 20 lbs of boost.

Must be nice.. When the prices come down on those 03 Cobras I might consider one for a daily driver.. I will keep my SS for racing.. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

Fellas, the exhaust you are talking about, the 3inch exhuast, is the one I have ordered. Its a very nice setup and from what I've seen, the strongest 03 Cobras are using it. You can check it out at www.LS1Motorsports.com/cobrapage.htm
Mr. Raymer sells a very nice exhaust, its not cheap but the best parts are never cheap.
