My roommate has a bone stock 99 cobra with 5 speed. Only mod is gutted cats. I have tsp lts ls6 manifold tune lca lca relocation brackets sfc panhard and new tires. Every time we race i see nothing but tail lights from him. Wtf. I don't want to risk messing up my car by manually shifting so I put it in D. We do a 25 a 30. I just can't beat him. Is it because I floor it on the 3rd honk and it take a second to kick down and by then he's already taken off? I don't spin or anything. Any ideas? I don't see why his stock vs my mods beats me. Any idea?!?!?!

Manually hold the proper gear. You will out run him then.

There's no hidden shot. Iv worked on the car with him. He swears I should beat him. I'm just scared to do it manually cuz Iv never raced by manually shifting. Idk how to do it.

Good lord. You have a 01 z28 with lt's and can't outrun a stock 99 cobra? We can't tell you if it's because your flooring it on the third honk but it should be pretty obvious if he is getting a head start that way. Now if it was a Mach 1, you will get beat by about 15 lengths.

No way a troll. Serious wtf moment. Take your "troll" ass somewhere else.

Think it's the second for it to kick down where he gets the jump?

Had this same thing happen in my Mark vs my brothers CROWN VIC cop car..talk about embarrassing.

You need to start in the proper gear (most likely "2", but I'm not familiar with LS1 gearing) and then carefully manually shift over to "D" at redline. Make sure O/D is off.

Practice this on a few wide open stretches.

for a 60 roll( 2.xx gears), I select second, wait for beeps, got wot on third beep and then click it back into OD before I get anywhere near my shift.

I NEVER keep it in OD and wait for kick down, sometimes it will go to third and not second at first and thats an instant loss of a race.

But, you should be able to punch it after him and still run him down.....you should be WAY up on power.

hit it on the second honk so by time it drops down and goes its the third, I lot of my auto buddies do that. Anyway your car is either fairly unhealthy or he isnt telling you about something on the cobra.

Now if it was a Mach 1, you will get beat by about 15 lengths.

My dad had an 01 z28 completely stock and beat our neighbors Mach1 that had exhaust and tune. Mach 1's are fast but theres not as fast as what people think and my neighbor will tell you he lost.

idk how true that is. Checking casting numbers. Even if it were true and say it were a mach 1 engine, it should still be a close race stock for stock.

That was only for 2003 and early 2004 32V Mod motors (Cobra & MACH). The passenger side head would develope a tick supposedly for an overheating or lack of oil to the valves on the cylinder nearest the firewall. Ford would do a replacement on the head. The later 04 head had a colored mark to designate the new version heads. I was not aware of this on the 99 or 01 Mod motors. My 2004 MACH has the markings on the head since I ordered it in March of 2004.

...like someone stated above...you buddy's car could have replaced the Cobra motor with a MACH motor at some point.

what would some things to look for to see if its a mach engine?

LOL..Not trying to be funny..but the whole shaker assembly and intake. I just could not see someone taking off the intake of a 99 Cobra and putting it on a MACH 1 motor. They could remove the shaker from the MACH motor but you would still see the mounting points on the manifold for the shaker. Other than that, I think it would be difficult since the mods were really to the redesign of the heads. Many of the parts from the 99 Cobra motor such as the Coil covers and cam covers were interchangelable...so I think it can be hidden nicely.

Don't know if anyone would go that far though..but you never know..

Maybe your tune is f'ed up.

Before your race slow down to 20 or so, put it to the floor and wait for it to down shift. Once it has, drop it in 2nd. Once the race starts bump it back into D.

No matter how you race you take the chance of breaking something.

OP my friend bought a stock 99 cobra last weekend and after some research I did for him about his car here are some things I found out. In 99 the Cobra's had an issue with not making the power that Ford advertised it to make. Ford would replace or acid dip the intake manifold reflash the pcm and change out the cat back exhaust. Ford said that this would 100% provide the power that Ford had advertised. The green dot that has been mentioned was to notate that Ford had did the power recall to that motor. In some severe cases Ford would actually replace the motor but in most cases just the parts I mentioned before.

08-11-2012, 11:53 AM
And was it making more or less than what ford said it was making?
I'm Gunna race him again today.
I'm not scared to race any mustangs except the termis and gt500s I haven't had a problem before with mustangs. Iv been with him when he's raced a trans am with similar mods and same outcome as our race but the ta was further behind. And he said he raced a SS same outcome. Idk wtf.

This was with the first batch of Cobra's released, and even after the fix they were still high 13 second cars at 103-ish in the 1/4 mile. No monsters for sure. A stock A4 LS1 should have no problem running door to door or pulling slightly up top.

OP is probably just having a little fun here. lol

even so those are losing times to a stock ls1 car, let alone a modded one. Op do you have any track times for either car? Id take my car to a tunner and see whats up.

BigBirdLS1
08-11-2012, 02:35 PM
They are definitely losing times to a stock f-body from a dig. But two different cars with very similiar 1/4 times from a roll the advantage is in the M5 > auto everytime.

But I agree the tune needs looked at. With the longtubes the A/F may be a little off and the 02's could be lazy.

93 LT1 Vette
08-11-2012, 02:51 PM
Take it to the track and come back with some times. You should be in the low 13's maybe 12's with 3.73's, exhaust and intake. If it's greatly slower it's hurt in some way.

Dude your car to begin with should trap several MPH over his. My car with a lid M6 draged a 104mph car from a 20 (spun pretty bad), and 40 roll with the car running shitty. Your car with the bolt ons it has and the tune should walk past it. Take it to the track if it traps shit MPH, do a leak down test.

Edit: OR the guy can easily be spraying and just not saying anything, which is something needed in the ford world.

Both of these... the best times I've ever heard from stock '99-'01 Cobra were right around 13.4 @ 103mph. With a great driver it should be very close with a stock A4/2.73 LS1 F-body, but from a roll or when the F-body has gears and LTs it really should be no contest.

14K..there is nothing wrong with your car or your driving. Don't let the haters on this forum make you feel like sh*t. The fact that a "Ford" gave you a run for your money is the reason for all the hate on your thread. Don't pay no attention to these guys....just mod up and go run him again. No shame in losing.

Just remember..you are on LS1Tech and the hate for Mustangs preceeds all logical thinking so don't expect anything more than crap talking from your fellow GM guys.

When you run him again..get it on vid and maybe some of the more "rational" guys on here can give you an idea on what is going on. :cheers:

If your race are less than an 1/8 mile you aren't giving your car a chance to catch him. And btw if you are doing a roll in an auto make sure you don't slow down from say 60-30 accelerate from 0-30 that way your trans WILL already be in first or at least downshift to first. That what a friend with a A4 T/A said helped him out.

Less than an 1/8 from a 30 roll, does it ever shift out of 2nd? Run him up to 120 or 130, then tell us the outcome.
