ive been thinking about challenging this rich kid in his 2001 Cobra vert. the fastest ive seen him go was 13.7. then about 2 months ago, he claimed he went 13.2, and now he says he went 12.7. i think this is complete . so i did some detective work and found out what the car has done to it:

- pulleys
- hypertech power programmer
- cold air
- hpipe
- cat back
- 4.10 gears

the best part is hes not running any kind of stickier tire! no drag radials or anything! so what do you think the car is capable of with an average driver?

 

Not to burst your bubble but a guy I know with a red 99 Cobra has flowmaster mufflers and cut off his cats. He ran a 12.9 swear to G0D. I didn't believe thats all he had done and I figured he had gears, nitrous, blah blah. But I looked his car over VERY hard and found nothing. Went for a ride and he has stock gears. Now he can drive and he has gone through 3 transmissions doing it but he did pull a 12.9 and he is around a 13.0-13.1 all the time. On stock radials too and he pulls a 1.7-2.0 60'. Just letting you know, don't let your guard down yet. Especially since he has 4.10 gears.

 

average driver that vert would be lucky to see low 13s. Good driver he could be in the 12s.

 

i dont doubt it. those cars do have great potential. but like you said, it takes a skilled driver with a high rpm launch to bring it out. i dont think this paticular guy has what it takes. we probably wont race until the track reopens sometime at the end of Feb. so ive got until then to get my combo sorted out.

thanks for the honest response, Monkie

 

Well, MM&FF got a 2001 convertible to run 13.3 Bone stock, but we all know Evan Smith (who drove that car) is a professional driver.

But i have seen other '01's in the 13.6-14.0 range stock with average drivers on the Mustang boards. The '01 motor has a legit 320HP so it is pretty fast. A good driver should solid 13's.

Biggest mod that the Cobra's love is 4.10's. Those DOHC cars love to rev and stock 3.27's are way too low. With the 4.10's alone could knock .3-.5 off the ET.

With the mods you listed, he would have the potential to run at least a 13.0 if he can drive or hook up.

But most younger Mustang drivers can't drive worth a damn. I say 13.3-13.5 for him.....slower if he really sucks

 

Not really. All the 4.10s are good for is your sucky drivers. The reason being it leaves alot more help for the driver. You can launch from idle and still make off with a good launch. Now obviously if you are running sticky tires with a solid axle lower gears will help you there too but we are talking about street driving with street tires. I put in 4.10s because everyone on the Cobra board was "OMG BEST MOD!" and they are nice. Makes your car feel alot stronger than it really is. But since he has 4.10s and if he slips the clutch at say 2,000rpms and comes off with very slight wheel hop you will be in serious trouble. Launching on the street is alot easier than launching at the track on street tires and launching a DOHC Cobra engine with 4.10s on the street is easy. Launching a DOHC Cobra engine with the stock gears is much harder. But most of the time it will result in better mph and better ET. Reason being is you can stay in your power curve alot longer than you can with 4.10s.

What are you racing him in? You Corvette? He will murder you out the hole no doubt. If I were you I would get gears for your car or something. I don't know much about automatics but I see you have 3.07 gears...yuck. If you really want to humiliate him go from a 75mph roll. I'll keep it my secret but it will be funny. I had a 200hp turbo Eclipse hang with me from that kind of roll. Just do it and post the result. :sillylol:

Actually his Vette is pulling 1.9 60's consistently, and since you think the track is worse than the street for launching, he will be pulling near 1.8s on the street, with the 3.07 gears! I would put my money on the Vette, because there is alot less room for error, and it sounds like there is a better driver behind the wheel!

 

maybe, maybe not. i consistantly pull 1.87- 1.90 60fts at the track. this is with the stock 1300 stall converter and with a light burnout on my BFGoodrich DRs. did i mention i also have the tranny out and a 2500 stall converter is going in? thatll enable me to launch at about 2000 rpms instead of 1000. alot of guys on the Corvette Forum use the same converter and they get mid - high 1.7 60fts consistantly. after the converter swap, i should be pulling 12.8s or so. i think the race will be close, coming down to the driver.
yeah, at first glance it looks like... YIKES that dude needs some more gear! but 3.07s arent all that bad for a TPI motor. like you stated about the stock gearing on a Cobra, the lower gear ratio helps keep my motor in its powerband longer (2000 - 4500 rpms). alot of Vette guys are deep into the 12s with stock 3.07s. not only that, but its a major PITA to change gears in a C4. we have all that IRS stuff and the leaf spring in the way of the diff. its not easy like on the fbodies. in fact, short of drilling a hole in the rear, the only way to change gear oil is to stick a syphon (sp?) pump into the fill hole and suck the old fluid out!

 

4.10's + power + average street driver + street tires = ridiculous wheel spin

 

I'm pretty sure you will beat him. He has to shift alot but if you can get the lead by the time he hits mid 2nd you will have him. Post the results if they come.

 

Couldn't have described it better.

 

Not with a Cobra. You have to remember it doesn't have near the torque a single cam V8 has. But yes if you rev it up in the slightest with 4.10s it will light them up. But if you punch it from idle you would be fine. When I was N/A I found slipping the clutch at 3,000rpms the best way of launching.

 

dude your missing the key variable....average street driver. thats like your mom driving. i dont care what kind of car it is....

besides its not like the cobra has 20 ft/lbs down low, if you launch the car hard with street tires its gonna roast the tires bad. i watch rejects with cobras do it all night long up at NED. what the car is capable of doesnt come into effect until you bypass the "average street driver" level

especially with 4.10's

 

i smell yet another flame war with monkie.

back to the original post, tpi vette you shouldnt have a problem beating this mustang.

 

It'll probably be a pretty good race, if he can drive. Once you get the converter you should have no problems at all.

And 4.10's do help cobras lanuch, but they certainly dont make the car launch itself.

Last time I was at the track with my buddies '97 cobra (that has 4.30's and Nittos) I was still able to completely bog the launch and pull a lousy 2.0 60'er. It still takes a good deal of clutch slip to launch perfectly.

And Monkie hit the nail right on the head...after dyno we found out that his torque peak came in at around 5,000rpm.

i want to say you might take him..
