i know of a couple people who have 03-04 mustangs, and they both have 3.8L or 3.9L's, i asked them if cobra and they said maybe, the didnt know...?

A Cobra is a 32V V8. Nothing more, nothing less.

wraitherx · February 23rd, 2009, 10:39 PM

No they are not cobra's.

Fuggle, please feel free to ask questions, but please don't start handing out tech advice if you aren't sure about what you're talking about. This is the 4v Forum, it's for Ford vehicles with the 8 cylinder 32v DOHC engines.

all and any cobra mustang is a v8. the 03 and 04's are supercharged.
the t bird has an m 90 supercharger not an m112. you CAN upgrade the m90 to an m112 however it is not really efficient nor worth the money. Not to be a dick, but please do not post in the tech section and give tech advice unless you are absolutely sure what you are talking about. Everyone was new to mustangs at one time. This is a tech site though and misinformation can lead to broken motors.
If you however have a question regarding mustangs or fords in general feel free to shoot me a pm or ask it in the correct section here.

First read some past threads if you have any questions as many have been answered a few times in the past. If you still have questions fire off a thread or PM HMUSN since he kindly offered.

I do like the pic in your av though. Got a full size?

in mid 2004 ford went from the 3.8 to the 3.9 in the v6's

am i seeing things? or was that dude banned or something?

03SonicBoom · February 24th, 2009, 07:39 AM

I have a honest question about the Cobra. The Cobra puts down ~370rwhp and runs a high 12 w/ a good driver. Somewhere on here somebody (I don't remember who) is running a New Edge w/ HiTech Stage 2 cams and puts down ~300rwhp. I've seen the video of him running low 12 (I believe it was 12.1 but don't quote me on that).

Why is the Cobra so much slower w/ much more HP (they seem like they would practically be the same car except for power)? Is the torque curve not as good? Does the Cobra weigh a decent amount more? Is it b/c the Cobra is IRS? Is it just a stock traction issue? With just some suspension mods could the Cobra hit 11s?

I just don't understand why two cars that seem VERY similar (except for engine) are running such different times.

03/04s unlike 96-01 Cobras have an Iron block which is heavier. They have a T-56 6 speed which is heavier. They have IRS which reduces unsprung weight but is still heavier. Supercharger weighs more, and so does the larger cooling equipment.

Result is a car that has much more power, but runs nearly the same 1/4th as my 100% stock 97 with 305 crank hp and extreme weight reduction. I think they would run faster if the IRS was changed, mainly because they cant launch as easily. Now they have a mean top end which really makes it a faster car. I dont doubt that if the track was longer my car wouldnt fare as well. A mod or two and they are out of my territory until I get more work done.

They respond VERY well to mods though and its easier to get them much faster before you need to tear into them.

several cobras have pulled off mid 12's...

but a better answer to your question would be that the one your talking about (probably trevors?) had suspension work with a built rear launching at 6grand on slicks

Right. So with suspension mods and slicks on a "stock" 03/04 Cobra (motor is stock) could it hit 11s? Or is it a weight issue and the Cobra is to heavy?

Smoothgrandmama · February 24th, 2009, 04:05 PM

Slicks, cai, exhaust, anti wheel hop kit, pulley and a tune and you should be in the 11's with very little seat time

That's not what I'm trying to understand. You're telling me that increasing power and suspension will get them in the 11s.

I'm wondering why a 300rwhp New Edge is running 12.1 and a ~370rwhp Cobra is running 12.7ish. The answer is suspension and the Cobra can't hook as well.

Now I'm wondering if it's possible to "fix" the Cobra suspension so it grips and put it into the 11s w/out engine modification. Obviously you can add more power to the Cobra and a few suspension mods to get it there. But if a 300rwph New Edge w/ suspension can get 12.1, can a 03/04 Cobra w/ suspension break into the 11s? If not, I guess it must be a weight issue?

Smoothgrandmama · February 24th, 2009, 04:28 PM

That gt has a crapload of suspension and prob some weight reduction as well. and yes if you go and spend 2k on suspension with some sticky tires you can put a cobra in the 11's

rk_2000_Z/28 · February 24th, 2009, 05:50 PM

A 300+ hp GT running a 12 flat has probably got some serious tire on the back, and I'm willing to bet quite a bit of weight pulled.

Put the same wheels and tires on the Cobra, and see what it runs. I bet the gap is quite a bit smaller.

And yeah, the Cobras weigh a crap load more than the GTs.

SilverFreakGT · February 24th, 2009, 06:17 PM

Cobra = heavy =) not to mention more of a top end car like someone mentioned earlier. My buddy has a stock 03 cobra and his car doesn't feel significantly faster than my car until the higher speeds. Obviously he has way more power but my lighter weight and shorter gears makes the low speed gap smaller than it should be. So the 1/4 mile heavily favors a 0-100mph (geared cammed full supsension GT) car where the cobra is probably more of a 60-150mph car as far as sweet spots go.

futureMACH1racer · February 27th, 2009, 01:24 AM

This threads smells of good tech. Keep it up boys and girls

.

Suspension and chassis mods always prevail IMHO. That is why I build my cars from the ground up. wheels, tires, brakes, suspension, chassis work, and weight reduction are the first mods that any of my cars will see.

NeverEnuff · February 27th, 2009, 03:37 PM

Ill take the IRS over the Solid anyday. the ONE and ONLY drawback is weight. If you build the IRS right, and KNOW how to use it at the track and on the street, it will 60ft better. At least mine does...and a few others I know of.

Def on the street for sure.

+1...the IRS can be built correctly to handle the power if you like it and don't want to swap it. As stated the only down side is the extra weight.
