blackfang said:No according to the statement you made, it is 100% false. You never stated redline top speed. The fact is you take a modular Mustang with stock gears and run it to a top speed on a clear road for 3 miles. Then take that same car with 4.10's or 4.30's and it will hit a higher top speed than when using the stock gears. The gears allow 4th and 5th gears to be more usable and allow the engine to pull the car in higher gears at a higher mph where the stockers won't.

i have seen people on stock tires LOSE 2 tenths by adding 4 10 gears. this is why i dont have a gear yet because i just dont know which way to go 3 73 or 4 10 and its a 600 $ big step. i have been waiting for someone with 3 27 to get a 4 10 with the same set up and go to the track and see if they gained or what was gained.
i just want to see some timeslips from someone so i can buy gears

and that video of me vs. jasonh_86, while awseome because I won () is flawed as well. Not flawed, but our cars arent identical. VERY SIMILAR, but not identical. I looked at a few of our slips, there was 1 race where he actually pulled on me VERY, VERY slightly (I still won ), and another where I pulled away from him quicker than he pulled on me the previous race.
So what Im trying to say is, there are too many intangibles that a computer cant take into account. I appreciate the time you put into this thread, but Im sorry it is flawed. I will race a stock geared GT with identical mods any day and beat him. end of story.
With stock tires, it takes more skill to launch with 4.10's than with stock 3.27's. However, a skilled driver will be quicker with 4.10's. A non-skilled driver may actually be slower with 4.10's because he will spin the tires more, losing the advantage of the 4.10's. That's why I say the first objective should be traction. After you have traction, horsepower and gearing become important. Without traction, you might as well be driving a Honda Civic.ilbehaved said:all this is nice but where is the real timeslips of 2 modded cars one with 4 10 and one with 3 27 on stock tires not drag radials.

Justin03GT said:here is an example..its not perfect given the 6 month period in between runs...but with stock gears my 1/8th time was
60' - 2.02
1/8 - 8.81
the weather was better for that run than it was for my next comparison run with 3.73 gears, other mods being equal.
60' - 1.98
1/8 - 8.50
for that run, the temp was in the mid 90s with high humidity, clearly not optimal for the best times..but i picked up .3 by adding gears and slightly dropping my 60'- not enough to make THAT big a difference...
like others have said, computer simulations are fine for estimates, but they cant do real world and can only be taken with a grain of salt..

after switching to 4.10s, my first pass down the track was SLOWER than with my stock gears. SOOOOOOO, I adjusted my driving, and I was running .5 faster with the 4.10s on the same tires, same driver, same mods as before the 4.10s. Now Ive added a TB/Plenum and some better driving, and I'm running .8 faster.
