okay guys here it is. Remember how everyone said not to do the 4.08 final drive gears????? Well I did it, and let me tell you its GREAT. Pulls ALOT harder and its sweet with the vortech so I would sudject everyone do it. Well just an update so let me know what ya think

 

Can you post an in car video? What pulley are you running?

 

i dont' knwo how to post videos yet and im running the 3.12 its goign to get tuned wed so I will post everything after that with dyno pulls and all

 

i wanna see

 

let me just say its badass maybe forged will post a video of the dyno run

 

I'ld really like to see some track numbers. Did you ever track your car before adding the gears to compare? I would be willing to bet that you shaved off close to a half a second.

 

In for the results~

 

+1

 

I always figured for the 1/4 mile, it's better to trap near the upper rpms in a stronger gear with high boost than right after you shift into a weaker gear with lower boost

IMO it'll make a pretty sizable difference at the drag strip. I mean I really wouldn't be surprised at all if it knocks .3 or even .4 seconds of someone's time.

I run a 3.9 FD and as far as I know, was the first to use it (at least on the forums) in conjunction with the vortech over 2 years ago. I'll always recommend shorter gearing with the vortech as long as you have good enough tires to get traction

 

^^ +1 hate having to shift into 5th @ the end of the 1/4....

 

Personally IMHO 3.7 gears are the way to go if your running vortech!

 

You will be shifting into 5th with the 4.08 in the 1/4. I have wondered about the 3.7 but it just seems like such a small step and replacing the gear is not cheap. I would love to know if a 4.08 even though another shirt is involved, if it lowers the ET and adds MPH in the 1/4

 

no i havnt' tracked the car yet i wanted to get at least 425hp befor I did so wish me luck

 

Just keep in mind you can select the wheel size for your drag radials appropriately to get you through the 1/4 mile without that last shift. You're not necessarily stuck because of the gears. The tire *is* the true final gear. Would love to see a video also!
