A lot of good interesting info/stories in this thread

As for my opinion...I think there are WAY too many factors to say, "OHH EMM GEE, with 4.10s you will be burning through 1st and 2nd like nothing"(in general)...Here are just a few that I have noticed....



-Tire inflation
-Tire/wheel size/tire stickiness(sp? lol)
- Road conditions....you all know what turns/roads/surfaces you know you can rip 'em up in....and then there are some that just grip and gooo
-**DRIVER**
- Temp, humidity, elevation, etc.
-**Heat soak/ AC on.....First starting up and driving feels MUCH more stronger than driving home in traffic for a while in 95+ degree heat, etc.
- Etc. etc.....

Too many factors....YES, I believe a GT with 4.10s will light them up much easier than 3.31's/3.55's in the same conditions/driver.

....Just today, driving back from chiropractic school....I know there is this turn/road that seems like it was built to do a strong a$$ burnout....I will try the same procedure on another turn and will not get half the results

My two pennies

 

While valid points, maybe you should go read the first 7 pages? He covered about every thing you asked there.

 

lol were you on a oil slick by chance? I think the you have 3.55 so I find that very hard to believe that u light them up in 2nd gear from a roll with the mods you have listed. If so You must have been on that pavement mention like at mcdonalds lol..... chirped them sure but lit them up from a roll in 2nd with 3.55.....thats impressive with under 300 hp....

 

If it hasn't already been mentioned, have you checked your traction control? Needs to be off.

Oh nvm saw the response on pg 7.

Odd, manual having a hard time breaking loose. I can do it all day long in my Auto. Drop into D1. Turn off the TCS gently press the brake just to keep the car from rolling forward and just give it all she's got for a few second then let off the brake, let it start moving and tap into 2nd to get a little sideways.

That's on 3.31 gears btw.

 

Derf, we are talking about only using the throttle and not shocking the drivetrain by a clutch dump or in the case of an auto - powerbraking. I think everyone has a different definition for spinning the tires. A little chirp is not spinning the tires, its chirping the tires. If you get a solid second or so where you are actually spinning and you can see the revs go up faster than the car can actually accelerate, then you broke them loose. I think besides a few people on here, most are either exaggerating or they have mods that kill traction such as lowering springs, low profile tires, ect.

 

I have the stock 3.31s and stock tires... From a 1k-1.5k roll my tires grip until i hit 4k+ then they start to squell and sometimes break loose. If I drop the clutch I can spin all of first, most of 2nd and chirp 3rd i've i'm shifting very aggressively. And I don't have much more for mods than you. But I do drive at 400ft sea level, altho it gets to 110 degrees here so DA can get up there. But either way.. tires wont break loose from a roll. Gotta pop the clutch to make it happen, and you can do that with ANY gears.

 

In that case then a manual should be a cake walk with 4.10's I would think...? Of course tehre are a ton of factors to consider, street conditions, type and size of tire, rim (weight - unsprung) suspension etc.

Most likely the electronic throttle drive by wire system is to blame also. I have noticed these cars seem to have a 'progressive' throttle as opposed to 0-WOT. More like someone mention 0-25-50-75-WOT

 

Nah, it's just that these cars don't have a ton of torque down low, and once it starts kicking in, it's like "where did that come from?"

 

Lol.
Imagine if his car had better traction... he'd go in the 10s!

 

another factor that plays a big part in traction is the power band of a car.

If a car has a very smooth progressive power band it would make it more difficult to burn rubber even with short gears and a good amount of power.

On the other hand if a car has a very peaky power band then its a different story.

Take the toyota supra turbo (mkiv 93-98). These cars can make huge amounts of power but their powerband is also very peaky, and thats why they have issues hooking.
I have seen 500rwhp supras melt their tires on a 3rd gear roll, while doing so in a mustang with the same amount of power would be much more unlikely.

why?

V8 motors tend to have good low end torque , and a good high hp as well. This equates to a smooth thick powerband that grows well with rpm.
The supra (and many other imports) can't do this. The supra has a tiny 3.0 inline 6 that is basically dead up until 4500 rpm. They produce no low end torque. So what happens is that the supra will bog hard if you slip the clutch and roll the car off of 2nd gear, and it will slowly creep along at full throttle until 4k+rpm then in a matter of about 600rpm the powerband goes from about 180lb/ft tq to 500lb/ft tq. this is an explosion of power that destroys the ability to grip of even the stickiest tires.

Musatngs and other v8 cars, do not go threw this, and this is why it is sometimes hard to smoke the tires on a Mustang on a roll. not that they can't, if a v8 car is putting down 800rwhp it would smoke the tires at will. But even then said car would be able to cope with its power better than an 800rwhp supra. Thats why we kill these Toyotas at the track.

Gripping is not a bad thing friend.
