Race with a COBRA.......Would I win?

[JEly]

Ok heres the deal... ... ... I work with a guy that is a HUGE FORD fan and he has a 04 Cobra with a few mods and he has "offered" me a race and here is the deal... ... ... ... ... ... ... We will race for 1 mile----he will give me a 1/4 mile head start what do ya think my chances would be.

Oh yea he wants to make it for $500 bucks.

I think my truck has some giddyup but just not enough to last a mile.



Thanks

JIM

he'll eat your lunch...

 

[WStoops]

I agree, he'll eat not only your lunch but your $500. Since you outweigh him by probably 3,000 lbs tell him he has to hook up a 3,000 lb trailer then do it. You MIGHT have a chance then. Why not just send me the $500. I could use it more than him.

 

[BApple]

No chance for you, unless you are HEAVILY modded. I have to say though, offering a truck to a race against a supercharged V-8? I could understand if you offered the race but him offering is a joke. That's pretty funny. He must only want to race others who have no chance of beating him. These are the types of guys I love listening talk trash but once I tell them what I'm running they don't want any part of me. Maybe he should just stick to racing opponents who are twice his weight, he should win those

If you uprade your trans and 1/4 mile lead, light"en up everything, with the mods you have it would be close. . O! remove the 315"s and go to 265"s

 

[moolie]

get yourself some mach 6 edm's and then go for it

 

[SRadke]

You don't have enough turbo to stay in it that long... . The wise choice, say no and keep your money.

[WyattEarp]

keep the money

I agree don't take that offer, now if he wants to race you in another truck then i would say probably yes but in an '04 cobra... no no no... . yeah sounds like one of those guys that thinks he has the ultimate under the hood, sure sounds sweet on his end, * I will just race this truck since he his 3000lbs heavier than me and he can pay for my dinners for the next month* type of guy... .

Tell him the local police dept has a chevy impala that would love to race him anytime anywhere LOL>. . :-laf

What about the 60 foot times?

Yea, the Cobra will "walk" on the top end, but can the 4x4 (4x4 engaged) pull him out of the hole. If so structure the race at a race track, (it's legal there) and race for the 60 foot time provided by the drag strips timers. What do ya'll think? Just my two cents.

 

[mr.billh]

I would race him... ..... but I get to pick the day. Fresh six inches of snow would do nicely... ..... uuuuRah... ..... $500 for more toys

 

[ScottBrown]

If you stomp on his snake before he lets it out of the cage, you would win. May Steve Mcqueen could help you out

 

[J.Davy]

It depends on what type of head start you mean. If you are side by side and he lets you pin her for a quarter mile,then nails it,by the time he is going you are almost up to speed . This means you only have to travel the last 3960' at a rate of (for the sake of easy math)120 mph or 10560' a minute or roughly a mile in thirty seconds or . 75 of a mile in 24 seconds. So can he start from a dead stop and cover a mile in 24 seconds taking at least 13 seconds to cover the first quarter and leaving only 11 seconds to cover the last three quarters fo a mile?I think if you talk him in to doing it this way you might be 500 bucks richer.

 

[J.Davy]

I did the math the other way,and to make a long story short, from a dead stop you should roughly take 30 seconds to cover 3960 feet if you could get up to 120 mph. If he could get up to and average 150 mph fot the last 3960 feet it would take him 18 seconds to cover that distance plus another 13 or 14 to do first 1320 feet, that puts him 1or 2 seconds behind. This is all based on both of you starting from a stop but you a 1/4 mile ahead. You guys do the math and let me know if I am wrong.

 

[wxman]

J. Davy, I generally agree with your math. In your first example, the Cobra would have to average over 240 mph to cover 3/4 mile in 11 seconds!

 

[DaveMorris]

I have had these kind of guys talk trash to me also with my Cherokee on 35"s... I tell them that we will do two races (one designed for thier car and one designed for mine): (1) on his conditions, and (1) on mine... we can time the difference and see who has the biggest time between the two :-laf ...



Now if I was in your shoes, I would make race (1) on a dry stretch and of course he would win, the race (2) would be at the local sled pulling track a good 5K on the sled should allow you to zip down the track... and then time him and see if when he finishes it :-laf ... . then everyday after can you walk buy him at work and say "still counting :-laf " (since he would never even get the sled started, much less finish) ... .



A horse is a horse, you are racing a Clydesdale against a through breed... he is going to smoke you on speed, but couldn't even bat an eye if you evened the playing field... .



PS your truck will never do 120, 108 is the limiter (unless you play with the computer)...

 

[Big MAK]

If he doesn't start until you reach the 1/4 mile marker -- you're already doing 92mph (134 ft/sec); you'll cover the last 3/4 of a mile in 25 sec.



The snake bit pony will probably run the 1/4 in just over 12 sec at about 120mph.



The problem is in the top speed department. The cobra has a top speed of 175. Against your 108. There's a gear issue here!



But you have a substantial head start!



Cobra (top speed of 175):

0->1/4 : 12 sec

1/4->1/2 : 5 sec (227ft/sec * 1312ft) - now at top speed 255ft/sec

1/2->1 : 10 sec (255ft/sec * 2625ft)

------------------

27 sec



CTD (top speed of 108):

0->1/4 : 0 sec (doesn't matter)

1/4->1/2 : 9 sec (145ft/sec * 1312ft) - now at top speed 157ft/sec

1/2->1 : 16 sec (157ft/sec * 2625ft)

--------------------

25 sec



the CTD would WIN by 2 seconds.



Surprises me!



Just past the finish line; stay out of the way; he'll blow by like you're standing still! Make sure the course is well measured and he doesn't jump the start.



IMO; the cobra is going to have a hard time reaching it's top speed by the 1/2 -- little torque to fight all the drag at that speed -- and the CTD will easily reach it's top speed by the 1/2. So I think this is a safe calculation. But you never know; what if he has more gear; etc.



The accuracy of the calculations depends on the accuracy of these assumptions:

1. the CTD is doing 92mph at the 1/4; and 108mph at the 1/2.

2. the Cobra is doing 120mph at the 1/4; and 175mph at the 1/2.

 

[Forrest Nearing]

hmm... I thought he was setting you out 1/4 mile and you were leaving at the same time... didn't realize you were doing 85mph when he leaves... that's a totally different story.



Forrest

 

[Big MAK]

Yep; it depends entirely on whether or not it's really a HEAD START! If they're starting at the same time; but the CTD 1/4 mile ahead; totally different story for sure.

 

[Steve St.Laurent]

The hard part will be making sure that he gives you a full 1/4 mile head start. I've drag raced against someone that was dialed in 7 seconds slower than me (which put him at about 1/2 track - or an 1/8th mile away) and it seemed like I was waiting FOREVER!! You'd need to have someone be a starter with a spotlight or something that can be seen and put him/her at the 1/4 mile point and start him as you pass them. I think you'd have a pretty good chance but I'd try it on your own at first to see what your EGT's would be. I know my truck would be dribbling aluminum out the tail pipe by the end of the 1/4 since I hit about 1550 at the end of the 1/4.

 

[rashwor]

See if you can get him to do it just for grins. I doubt you could win... too many things have to be just so and I would not be comfortable putting $500 on it. If the Cobra is anything other than stock, you can't win with his criteria. They are truly bad*** cars and 7000lb trucks were not designed to race them.



I just smile in admiration when one streaks by me at 90+mph and I am loaded. It means the weights and measures guy down the road will be busy when I get there!
