I'm thinking of dropping a set of FMS 4.30's in the car when I get it....

Does anyone have any times before and after a gear swap? What about on radials?

 

If you want any benefit out of the gears, you need to get drag radials. It's the general consensus around here that Mickey Thompson ET Streets (biasply) have the best traction for a DOT tire. The 3743 model fits on the stock GT tire.

You will pick up 2-3 tenths at least and 3 tenths with the slicks. With an intake and tuner your mods will put you in the 12.7-12.8 range.

 

Anyone want to take a stab at what kind of gains i will see with swapping out my 3.31 open diff with a 3.73 truetrac diff (and adding the gt takeoff rims tires)?
My ET before was a 14.73

 

I don't know anything about v6 performance

 

So if I'm not planning on running drag tires, gains would be quite minimal? I'm looking for a pure comparison, same tires, etc...

 

With stock tires you will see .1 or less of a gain, people say. You will be losing traction.

 

I would think it could be more than that on stock tires. At least I hope so...

 

I went from 13.6 with an automatic completely stock to 13.2 with 4.10 gears and a tune on street tires. I am going to add underdrive pulleys and hope to run 13.0 or 12.9 with stock tires.

 

Again I'm not speaking from personal experience, that's just what people have said here.

 

How did you run 13.6 with a completly stock auto? You must have some special trick, i wanna know.

 

I went 13.73 Bone stock. I could have gone quicker but it was my first time at the track.

 

how thouh, lower pressure? what did you launch at? i wanna get quicker like that, did you leave it in D?

 

I really wasnt trying to get a good time.I wanted to see how well the car ran. I left it in drive and with the traction control on. The 60' time sucked as you can see.
